Paver Patterns Explained: Herringbone, Basketweave, and Ashlar

Paver patterns do more than dress up a patio or driveway. The geometry affects strength under load, traction when wet, how easily you can drain stormwater, even how large or intimate the space feels. In Southern California, where clay pockets, irrigation changes, and hillside conditions all come into play, pattern choice can be the difference between a crisp, long lasting surface and one that creeps or ruts after two summers.

Across projects from Pasadena to the Palos Verdes Peninsula, three layouts consistently rise to the top for hardscape pros and design minded homeowners. Herringbone, basketweave, and ashlar are versatile, time tested, and customizable enough to meet modern demands. Each asks for different planning, different base prep in some cases, and different expectations for cost and installation time. Get those pieces right and the surface will serve for decades.

What actually makes a paver pattern “good”

People often pick a pattern by mood board, then discover during layout that a driveway cart path needs more interlock, or the patio joints do not align with a French drain. A good pattern solves more than style. It needs enough interlock to resist traffic, joint paths that work with your drainage plan, and an edge strategy that locks the system together.

Interlock is the quiet hero. Tight, directional interlock transfers wheel loads laterally from paver to paver, so no single unit gets crushed or shoved. Herringbone leads here. Basketweave and ashlar interlock well when sized and oriented correctly, but the performance changes with the joint alignment and the edge restraint. You also need the right base. In Los Angeles, patios usually carry a compacted Class II road base of 4 to 6 inches, topped with about 1 inch of bedding sand. Driveways typically need 6 to 10 inches depending on soil and vehicle weight. Hillside terraces may require geogrid reinforcement in lifts, and drainage layers tied to a daylight outlet or a sump. None of that flair shows in the final photos, yet it determines whether the pattern does its job.

Permeability is another puzzle piece. If you are exploring water wise upgrades that align with the Best Plants for Low-Water Landscapes in Los Angeles, permeable pavers can filter stormwater into an open graded aggregate base. That system changes joint width, joint infill, and base depth. On the last hillside project we completed in Studio City, the permeable ashlar courtyard used 12 to 18 inches of clean stone beneath the pavers, all wrapped in nonwoven fabric to preserve porosity, with joints filled in a 2 to 4 millimeter angular chip. The pattern looked random, but the substructure read like engineering.

Herringbone: the workhorse with presence

There is a reason herringbone dominates historic streets and modern driveways. The zigzag pattern creates a lattice of staggered joints that resist lateral movement from any direction. Laid at 45 degrees across a drive, it spreads braking and turning forces so well that tire scuffs and rutting decrease. Laid at 90 degrees, it reads more contemporary and can simplify cutting around rectangular features like a pool terrace or a linear outdoor kitchen.

Herringbone uses uniformly sized rectangular pavers. Common sizes include 4 by 8 inches in concrete or clay, and modular concrete units like 6 by 9 inches for a chunkier look. On vehicle traffic surfaces, I lean toward a thickness of 60 to 80 millimeters. If you plan to park an SUV or truck long term, 80 millimeters gives welcome insurance, especially over clayey subgrades that expand and contract through the seasons.

For patios, herringbone strikes a balance between visual energy and function. The eye follows the chevrons, which can expand a compact space if you run the pattern on the bias relative to the house. A client in Mar Vista had a small 12 by 18 foot sitting terrace that felt truncated when we sketched it in ashlar. Rotating herringbone 45 degrees added a sense of length and movement, and the border did the rest to hold the composition.

Edge restraint is critical. Without a rigid border, herringbone wants to spread. I prefer a concrete toe beam under a soldier course at driveways, with spikes set into the beam or concealed aluminum edging on patios where you want a cleaner line. Expect more cutting with herringbone. Waste usually lands in the 7 to 12 percent range, creeping higher on tight curves or if you choose 45 degrees on a perimeter with many jogs.

It is paver driveway Pasadena also forgiving for slopes. With joints oriented in multiple directions, herringbone offers reliable traction. Around pools, it pairs well with a light sand or dove color that stays cooler underfoot. In hot microclimates, a pale concrete paver can run 10 to 20 degrees cooler than deeper charcoal. That matters in August when a pool deck bakes by midday.

Basketweave: calm, classic, and deceptively strong

Basketweave alternates pairs or trios of bricks laid horizontally and vertically, creating blocks that look like woven strands. It is one of the few patterns that can read traditional or modern depending on color and border choices. We have installed basketweave patios in dusty buff and brown that felt lifted from a Craftsman bungalow, and the same pattern in smooth charcoal and platinum at a modern ranch that wanted graphic simplicity.

The pattern does not interlock as aggressively as herringbone, but it still performs well on patios, walks, and even some light vehicle areas when sized and supported correctly. I would not use a two piece basketweave of slim clay bricks on a driveway where guests crank the wheel at low speed. A thicker concrete unit, set in a tight basketweave and framed by a strong border, can handle cars just fine on straight approaches. On curves, pair the layout with an accent border that absorbs slight joint adjustments so you are not pinching or opening joints to force the weave around a radius.

Basketweave shines in courtyards because it quiets the field. The eye reads tidy blocks, not directional chevrons. That lets plantings, a fountain, or a fire feature lead. Homeowners in our 12 Backyard Water Feature Ideas for Los Angeles Homes often choose basketweave for the surround because the pattern does not compete with moving water. On maintenance, the fewer diagonal cuts make it friendly to a DIY minded homeowner tackling a small area, although base prep still needs to be right. Waste is efficient, often in the 5 to 8 percent range.

One caution comes up in Southern California clay soils. If you run long, uninterrupted stretches of basketweave without a border or control joints, minor seasonal movement can ladder up through those straight joints and telegraph as hairline separations. A soldier or sailor border set over a toe beam keeps the field in check. We also like to hide a control joint under an accent strip every 12 to 16 feet on large patios.

Ashlar: the modern classic with a crafted feel

Ashlar patterns use multiple rectangle sizes arranged in a coursed, repeating layout that appears random to the casual eye. They bring the feel of hand laid stone to concrete pavers or large porcelain modules, and they pair well with both Mediterranean and contemporary architecture. In Los Angeles, ashlar is our go to for expansive pool decks because it scales with the space and breaks up long lines. It also complements drought tolerant plantings because the varied joints feel organic next to gravel mulches and sculptural shrubs.

The trick with ashlar is control. Manufacturers supply a pattern sheet with a ratio of sizes that, when repeated, keeps cross joints from aligning. Do not freestyle your own layout unless you love fixes. The pattern usually repeats every 8 to 12 square feet, which is easy to miss as you lay but obvious in a drone photo. We dry lay a test panel to lock in the rotation and double check that pack ratios in the pallet match the plan. When crews skip this step, the install bogs down as they hunt for the next correct size.

Ashlar on driveways asks for thicker units and a focus on joint continuity. Where possible, align wheel paths so that you are not creating continuous transverse joints right under the tire track. We often shift the field by a half module at the midpoint of a wide driveway. The change is invisible, but the joints no longer stack under load. For permeable ashlar, the joint width can be larger to accommodate aggregate infill. That increases visual contrast, which is welcome on a modern home with smooth stucco and steel detail.

Cutting around round features like a fire pit is gentler with ashlar than rigid patterns because you can feather in smaller sizes at the curve. A round fire feature featured in 12 Fire Pit Designs Perfect for Southern California Entertaining used three ashlar sizes to keep cuts balanced, with a dark soldier ring tying the circle to the square field.

Borders, accents, and the art of restraint

Think of borders as both frame and structure. A soldier course, where pavers stand on end along the edge, gives a crisp termination line and contributes to edge restraint. A sailor course, with pavers laid lengthwise, elongates the border and can reduce the number of cuts along a curved edge. On modern projects we sometimes double up a border, a narrow soldier in a contrasting color set inside a tone on tone sailor. The inner soldier becomes the true restraint, and the outer sailor is the decorative reveal that allows millimeter scale adjustments on curves.

Color contrast belongs to the architecture. Deep borders around a pale ashlar field read formal. Tone on tone borders around herringbone feel modern and let the zigzag be the star. We choose borders with an eye toward maintenance too. A darker ring where rubber meets the road along a driveway apron hides tire scuffs. If you are blending artificial turf with pavers in a grid, a stainless or aluminum edge anchor beneath the paver border holds the turf infill neatly and keeps maintenance simple, a detail we often discuss in Artificial Turf vs Natural Grass: Which Is Better for Los Angeles Properties?.

Lighting belongs in the border plan. Hardscape lighting set into border pavers or capstones transforms the space at night. Done well, you get guidance, drama, and security with minimal glare, which aligns with the 10 Benefits of Installing Landscape Lighting Around Your Home.

Drainage, slope, and SoCal realities

Los Angeles soils swing from fast draining sandy loam near the coast to heavier clays inland, with countless pockets of fill and bedrock in the hills. The city gets modest annual rainfall, then a handful of big events. Your paver design should treat water as an early chapter, not a footnote.

Set slopes at 1.5 to 2 percent where possible to keep water moving. For pool decks, break drainage around the shell and plan for trench drains where grades pinch. Do not route runoff across long joint lines of basketweave where it can carry sand. Instead, integrate inlets and pop up emitters to collect water early, or plan a shallow swale in planted areas. If your site has hydrostatic issues or a seasonal river through the side yard, consider a French drain that relieves pressure under the hardscape. Everything You Need to Know About French Drains and Yard Drainage is a helpful primer, but match the trench depth, fabric type, and discharge to your soil and elevation.

Permeable pavers offer another path. They capture and infiltrate stormwater under the surface, which helps with local water tables and can ease permitting in some jurisdictions. They also require specific aggregates, a different base profile, and vigilant construction to keep fines out of the system. On steep hillside properties, infiltration must be evaluated carefully. Sometimes the right call is a conventional paver surface with subsurface drains that daylight safely. Why Proper Drainage Is Essential for Hillside Properties is not theory for us. It is weekly practice during design reviews.

Materials that suit Los Angeles light and heat

Concrete pavers dominate for versatility and price, with rich textures that mimic stone and a broad palette. Choose colors with a touch of variation to disguise dust and the mineral deposits that can crop up as efflorescence, especially during the first year. Clay brick offers saturated color that does not fade, a favorite for basketweave in historic neighborhoods. Porcelain pavers give a sleek modern look and run cooler underfoot than darker concrete, useful for pool decks. They are typically thinner and best over a rigid mortar bed, or on pedestals, not a standard sand set driveway.

UV is relentless here. If you love deep charcoals, pick a manufacturer known for integral color stability. On hot sites, lighter shades reduce heat and bring out plant greens. Pairing pale ashlar with The Best Plants for Low-Water Landscapes in Los Angeles creates a fresh, resilient palette.

Where each pattern shines

I think in scenarios, because most homeowners do. Here are typical applications that line up with performance and aesthetics:

Herringbone for driveways, high traffic walkways, and narrow side yards that need a sense of movement. It is also my default for a motor court that doubles as a hardscape play space. Basketweave for intimate patios, cottage or Craftsman architecture, and outdoor dining terraces where you want the furniture and plantings to lead. A subtle border keeps it tidy without shouting. Ashlar for large patios, pool decks, and modern facades that need a natural rhythm. Its scale options and mixed sizes tame broad surfaces and integrate with steps, planters, and retaining walls.

Base prep, joints, and the quiet details that extend lifespan

A pattern cannot save a weak base. Compact in thin lifts, test for 95 percent relative compaction, and proof roll the base before bedding sand goes down. In Los Angeles, I rarely place less than 4 inches of base for a patio, and most drives sit on 8 inches or more. Over expansive clays, add a separation geotextile between subgrade and base to keep fines from migrating. On slopes, step the base and use geogrid at prescribed elevations.

Jointing sand matters. Traditional joint sand is cost effective and easy to refresh. Polymeric sand hardens and resists washout and weeds when installed dry, swept aggressively, and misted correctly. In shaded or very wet spots, pick a polymeric product rated for those conditions to avoid haze. Expect to top up joints every 3 to 5 years on patios, hardscaping tips and more often on permeable installs that rely on larger joint stone.

Edge restraint is the unsung hero. A paver field without solid edges is like a puzzle without a picture frame. In curves, avoid over bending plastic edging, which can kink and telegraph through the border. We pour a concrete beam under the edge where vehicles turn or where tree roots will test the boundary.

Costs, timeframes, and what drives the range

Costs vary by site, access, and scope, but in Greater Los Angeles, professionally installed concrete paver patios often land between 18 and 35 dollars per square foot for a standard base and field pattern, with borders, drainage, and demolition pushing the number upward. Driveways typically range from 22 to 45 dollars per square foot as base thickness increases and cuts multiply. Complex borders, inlays, or porcelain upgrades add premium. If you are combining a new patio with an outdoor kitchen, plan the staging so trades do not trample each other. How Much Does a Custom Outdoor Kitchen Cost in Los Angeles? Depends on appliances and finishes, but tie the utilities and slab or footing needs to the paver sequence to avoid rework.

Timeframes track complexity. A 400 square foot basketweave patio with one border may install in three to five working days, including base work. A 1,200 square foot ashlar pool deck with step integration, trench drains, and two borders can run two to three weeks, contingent on inspections and cure times for concrete elements.

Common missteps and how to sidestep them

The most expensive mistakes rarely show in a sample booklet. People underbuild the base, skimp on edge restraint, or choose a pattern that fights the shape of the space. On a Brentwood project, a homeowner loved a 45 degree herringbone for a narrow, walled side yard. We dry laid a few courses and saw that every chevron ended in a sliver cut at both walls. The fix was a 90 degree herringbone with a clean border. Same vibe, zero slivers, fewer cuts, and a savings of about 8 percent in material waste.

Another regular is drainage shoehorned in after the fact. Retrofitting a catch basin into a settled patio is nobody’s lovely weekend. Design with water early, and set the pattern to cooperate with inlets, not defy them. For hillside designs, pull in a retaining wall specialist early. Retaining Walls Explained: When Does Your Property Need One? Ties directly to paver performance. A well designed wall with a drain behind it protects the flat space you worked so hard to create.

A short, practical guide to choosing your pattern

Start with use first. Heavy vehicles or sharp turning zones benefit from herringbone. Calm dining terraces or courtyards love basketweave. Broad pool decks often prefer ashlar. Match the architecture. Craftsman and Spanish Colonial welcome basketweave or ashlar with tumbled edges. Mid century and contemporary homes pair well with 90 degree herringbone or clean edged ashlar. Let borders do structural work. Pick a border that manages curves and offers anchoring. Design the drainage and lighting into it. Mock up before you commit. Dry lay at least 20 square feet of the pattern with border and jointing sand to judge color, joint line behavior, and scale against your house. Plan for maintenance. Choose jointing and sealing strategies that fit your tolerance for upkeep and the microclimate of your yard.

Tying pattern to outdoor living features

Pattern decisions rarely stand alone. If you want a pergola, its posts dictate layout breaks and footing locations, and your pattern has to respect those. 10 Pergola Ideas That Transform Outdoor Living Spaces shows how to use a border as a footing reveal so the pavers, not the footing, define the finished grade. Fire features work best when the pattern approaches the circle gracefully. Herringbone will look busy if you do not soften it with a ring; ashlar transitions beautifully with mixed sizes near the curve. For outdoor kitchens, we often rotate the field pattern to align visually with the counter face, then add a subtle inlay that acts as a drip line or defines a prep zone. Outdoor Kitchens: The Most Popular Features Los Angeles Homeowners Are Adding can guide appliance and layout choices, but the paver plan still frames the experience.

Landscape lighting integrates with the pattern too. Step lights set into ashlar risers or low profile hardscape lights beneath capstones accentuate joint lines without blinding guests. That dovetails with Outdoor Lighting Design Tips Every Homeowner Should Know and pays dividends during evening entertaining.

A field vignette from a Los Angeles backyard

One of our favorite recent builds was a sloped lot in Sherman Oaks where the owners wanted a family friendly yard that felt like a small resort. The driveway handled two cars and a turn into the garage, the side yard was their main play space, and the rear yard included a pool, a compact kitchen, and a fire lounge.

We used 80 millimeter concrete pavers in a 45 degree herringbone for the driveway, framed in a charcoal soldier course over a concealed concrete beam. The beam let us hold a perfect curve at the apron and gave the field the restraint it needed during tight turns. Tire scuffing was a concern, so the border color masked marks and the field color was a cooler mid gray that looked clean with little effort.

Along the side yard, basketweave in a warm buff made the narrow space feel calm. It ran straight for 38 feet, so we added a crisp accent strip every 14 feet that doubled as a hidden control joint. Drainage was set to a central slot drain that disappeared into the pattern. The kids ride scooters there; the weave keeps the area visually steady and performs well under the repeat traffic.

The pool deck used a large format ashlar with lightly textured faces for traction. We planned the pattern to avoid repeating joints at the tanning ledge and the kitchen edge. A low retaining wall, faced in the same paver color family, stepped the grade and hid a perforated drain that relieved hydrostatic pressure. Lighting tucked beneath the wall caps washed the ashlar joints at night, turning lines into subtle guides. The entire build echoed ideas from 15 Luxury Backyard Ideas Inspired by Southern California Living without feeling borrowed. It was personal, durable, and inviting.

Long term care and small seasonal rituals

Pavers are not maintenance free, but they are straightforward. Sweep or blow debris regularly so organic fines do not feed joint weeds. Rinse with a garden hose, and reserve pressure washing for stubborn stains, keeping the nozzle moving at a shallow angle to avoid blasting out sand. Most concrete pavers benefit from a breathable sealer every three to five years, especially in areas prone to leaf tannins or barbecue spills. Polymer sand joints may need topping up in high traffic spots after a few years. Efflorescence, the whitish bloom that can appear in year one, weathers out or can be cleaned with a manufacturer recommended solution.

Tree roots will find water and space. Where large roots approach the edge, we sometimes swap a rigid toe beam for a segmented restraint method that can be adjusted in future without tearing up a long stretch of border. On permeable installs, keep mulch out of joints and schedule a light vacuum sweep every couple of years to maintain infiltration, a smart companion to The Complete Guide to Drought-Tolerant Landscaping in Los Angeles.

Bringing it all together with design intent

Patterns are tools, not ends in themselves. The best projects tell a cohesive story across materials, plantings, and light. If you are after 15 Stunning Paver Patio Ideas for Los Angeles Homes, note how the strongest examples use pattern to shape circulation, frame focal points, and support everyday use. They also respect site realities. On hillsides, The Complete Guide to Hillside Landscaping in Los Angeles and How to Choose the Right Retaining Wall for Your Property intersect with pattern choice, because the substructure dictates what the surface can do.

A well planned paver layout increases property value not only because it looks good, but because it functions across seasons. How to Design a Backyard That Increases Property Value is really a conversation about clarity of use, solid construction, and timeless material moves. Herringbone, basketweave, and ashlar have earned their place in that conversation. Pick with purpose, build with care, and your hardscape will hold up to kids, parties, and the occasional downpour, all while making the daily walk to the mailbox a little more satisfying.
