How to Design and Install a Paver Patio

Designing and installing a paver patio can add beauty and functionality to your outdoor space. Pavers come in a variety of shapes, sizes, colors and textures, allowing you to create a custom look for your patio. With some planning, prep work and basic DIY skills, you can install an attractive paver patio yourself. Here is a step-by-step guide to designing and installing a paver patio.

Selecting the Location

When choosing where to locate your paver patio, consider how you want to use the space and how much sun or shade you need. Ideally, locate it near the backdoor for convenient access to and from your home. Other factors to consider include:

Sun exposure – For sunbathing and growing plants, select a sunny spot. For dining or lounging in cooler comfort, choose a shady area.
Drainage – Allow for proper drainage so water does not pool on the pavers with heavy rains. Choose a slightly sloped area or plan for drainage gaps between pavers.
Access to utilities – If adding amenities like lighting or a fire feature, consider access to electrical and gas lines.
Views – Position your patio to showcase attractive areas of your yard or landscapes. Frame views by using the house and plantings as a backdrop.
Privacy – Consider proximity to neighbors’ homes and sightlines from windows when positioning your patio. Strategic fences, plantings and trellises can increase privacy.

Select a flat, level spot if possible, or plan to build up and smooth out the base as needed. Outline the shape and orientation of your paver patio with spray paint or landscape chalk before finalizing the location.

Choosing Paver Materials, Styles and Colors

Pavers come in a diverse range of styles, shapes, colors and textures to suit your design vision. Consider the following when selecting pavers:

Paver Materials

Concrete – Affordable and durable, concrete pavers hold up well to heavy use. Available in many colors and styles.
Brick – Classic clay brick pavers offer a traditional, elegant look. More expensive than concrete but long-lasting.
Natural stone – Flagstone, bluestone, travertine and granite provide a natural, organic aesthetic. Labor intensive to install.
Porcelain – Made to imitate natural stone but with more durability. Stain and fade resistant. High cost.

Paver Styles

Interlocking – Precut blocks fit together snugly and stay in place. No cutting required.
Tumbled – Pavers are mechanically tumbled to create an aged, worn appearance.
Stamped concrete – Molded and imprinted wet concrete mimics brick, stone, slate or cobblestone.
Geometric – Unique shapes like hexagons, circles and fans create visual interest.

Paver Colors

Select paver colors that complement your home’s exterior color scheme:

Neutral earth tones like tans, browns and grays blend well with most color palettes.
Bold or bright colors can make a dramatic statement and define the space.
Contrast the hue of the home siding with lighter or darker paver colors.
Match existing hardscapes like a front walkway for visual continuity.

Get free samples from suppliers to view colors and textures. Combine a patterned mix of colors and shapes for added visual appeal.

Determining the Size and Layout

Measure your patio space carefully, accounting for any curves or irregular shapes. Use graph paper to experiment with different layouts and dimensions. Determine the amount of pavers needed by multiplying the length times width.

Consider the following when planning your paver layout:

Purpose of the space – Allow room for furniture, amenities and circulation pathways.
Geometric, grid or angled designs – More complex layouts require cutting pavers to fit.
Incorporating curves – Curves require cutting but add grace and flow. Allow a wider gap between pavers on curves.
Paver dimensions – Available sizes range from 2×2 inches up to 24×24 inches. Combine sizes for visual interest.
Joint pattern – Tight, wide or staggered joints create different textures. Wider gaps improve drainage.
Border course – Frame the outer edges with a course of cut pavers or edge restraints.

Make a drawing of your patio layout to scale to determine how many of each size paver you need. Leave room for cutting waste. Have 10-15% extra to allow for breakage, cuts and future repairs.

Preparing the Base

Proper base preparation is crucial for lasting patio performance. The base needs to provide a solid, stable foundation to prevent sinking or shifting of pavers over time.

Remove Existing Grass, Plants and Roots

Start by removing all vegetation within the patio area. Dig down at least 6 inches to eliminate grass, roots and weeds which could grow up through the patio later. Dispose of the sod and excess soil.

Level and Compact Soil

Fill any low spots with additional soil to level the area. Use a tamping device like a hand tamper to compact the soil.
Water the soil then check for level. Fill in any depressions with soil and compact again.
Repeat leveling, tamping and watering until the soil is compacted evenly. The base should be 2-3 inches below the final paver height.

Add Gravel Base Layer

Spread a 4-6 inch layer of crushed gravel (road base) over the compacted soil base.
Use a vibratory plate compactor to tamp down the gravel thoroughly in 2 inch lifts.
The finished gravel base should be 2-3 inches below the finished paver height.

Install Edge Restraints

Place edge restraints around the perimeter before adding the final sand layer. Options include:

Plastic or metal edging – Versatile, affordable and easy to install. Just stake into the gravel base according to manufacturer instructions.
Concrete curb – Provides a sturdy border but requires more labor to install.
Brick or stone – Matches pavers but raises overall cost. Set on compacted gravel and level with sand.
Wood boards – Use pressure-treated lumber set into gravel base. Stake boards together at corners.

Edge restraints help contain the sand and pavers at the edges. They prevent spreading or creep of materials over time.

Adding the Sand Base Layer

A 1-2 inch layer of coarse sand or stone dust provides the final, smooth base for directly laying the pavers. This is often referred to as the bedding layer.

Choose the Right Sand

The best sand for pavers includes particles that interlock when compacted:

Look for coarse builder’s sand, sometimes called concrete sand.
Do not use play box sand or other fine particled sand which can shift. Always check gradation specifications.
Stone dust, also called screenings, also makes a quality bedding material.

Screed the Sand Flat

Spread sand evenly across the gravel base, keeping the depth around 1-2 inches.
Use screed pipes and boards to smooth the sand flat. Place pipes along edges and use a straight 2×4 board to sweep sand level between the pipes.
Compact the finished sand layer with rented plate compactor. Mist with water to help settle sand into the gravel course.
Make minor leveling adjustments, sweeping off high spots and filling any dips. The bedding sand should be smooth, even and 1-2 inches below the paver top surface when complete.

Laying the Pavers

Now the fun part begins – laying the pavers! Follow these tips for managing the paver installation:

Set the Pattern

Start laying pavers at a 90° corner if possible, or along a straight edge as your guideline.
Use chalk lines snapped on the sand bed to keep rows straight.
Follow your pre-determined paver layout pattern. Adjust as needed while installing.
Mix pavers from several bundles or pallets to distribute color variations evenly.

Cut Borders and Pavers to Fit

Cut border pavers as needed with a paver splitter or masonry saw. Use a hand chisel to nibble smaller pieces.
Make interior cuts with a masonry saw. Mark cuts carefully with a pencil.
Use a mason’s hammer and chisel to cut pavers smaller than the saw blade width. Wear safety goggles and gloves.

Set Pavers Snugly

Place pavers hand-tight against each other to minimize gaps. Use a rubber mallet to tap pavers flush together.
Fill gaps wider than 1/8″ with stone dust to prevent shifting. Remove excess dust from top when finished.
Use string lines across pattern rows to keep straight lines. Adjust as you go to match edges.
Begin paver courses at right angles to one another to avoid aligning vertical joints which can compromise strength.

Tamp Pavers As You Go

Use a plate compactor to tamp installed pavers frequently as you go to settle them into the sand bed.
Check for level often with a 2-4 foot long board. Make adjustments by adding or removing sand below high or low pavers.
Repeat compacting and leveling until the pavers are fully set at the proper finished height.

Filling Gaps and Sealing

The final steps include filling the joints between pavers and applying sealant.

Fill Gaps

Choose joint material to match your project:

Polymeric sand – For a firm, mortar-like joint. Just wet to activate bonding agent after sweeping over gaps.
Stone dust – For a more casual, softer joint. Works for wider gaps.
Gravel or grass – If planning open, planted joints. Allows drainage and growth between pavers.

Sweep chosen material over the surface, allowing it to filter down into joints. Compact again lightly to settle material into gaps. Avoid stepping on pavers during this process to prevent grinding material out of joints. Then sweep off excess from paver surface.

Apply Sealant

Sealant protects the beauty of pavers and joints.

Allow pavers to cure for 72 hours before sealing.
Use polymeric sand joint filler and sealer products to streamline.
For concrete pavers, apply concrete sealer following manufacturer instructions.
For natural stone, use a stone and masonry sealer suitable for the specific material.

Sealing may need reapplication every 1-3 years.

Optional Enhancements

Consider incorporating additional design features to enhance your paver patio:

Fire Features

Fire pits, fireplaces, chimneys or fire bowls add ambiance and extend patio use into cooler months. Have a contractor handle gas line connections.

Water Features

The sights and sounds of fountains, ponds or cascades bring relaxing sensory elements. Set level on compacted base; allow for pump access.

Retaining Walls and Planters

Integrate brick, stone or concrete retaining walls, raised planters and bed edging for extra design detail.

Overhead Structures

Provide shade and shelter from sun or rain with pergolas, gazebos and trellises. Match architectural style to home. Consider lighting and ceiling fans for added function.

Railings and Steps

Incorporate railings or steppers on sloped sites or to delineate separate patio zones. Use builders stone or pavers for attractive steps.

Lighting

Outdoor lighting extends enjoyment into the evening and adds dramatic ambiance. Choose LED fixtures rated for outdoor use. Highlight design features and pathways.

Furniture and Decor

Comfy, weather-resistant patio seating invites relaxation. Plan space for tables, chairs, lounges, umbrellas and potted plants. Anchor freestanding pieces for added safety on a paver surface.

Maintaining and Repairing a Paver Patio

With proper installation and care, a paver patio can provide years of durable service and beauty. Follow these maintenance tips:

Sweep or blow debris from joints and pavers regularly to prevent buildup.
Watch for ants, weeds or moss in joints and treat as needed. Reapply joint material after weeding.
Remove stains from pavers with cleaners made for the paver type.
Pressure wash cautiously at low settings to avoid dislodging joint material.
Reseal pavers every 1-3 years according to manufacturer directions.

For repairs:

Replace individual damaged pavers by pulling up carefully to avoid disturbing adjacent pavers.
Remove sand, level the base, set new paver and reapply joint material.
To resurface the entire patio, rent a plate compactor with a special paver attachment to prevent chipping. Lift pavers systematically, add or replace base layers as needed, and reset pavers.

With thoughtful design and proper installation, a paver patio provides an inviting outdoor living space to enjoy for years to come. Maintain your patio well and make repairs promptly to keep it looking its best.
