Site preparation and excavation
Clearing vegetation and topsoil creates a stable foundation. Remove grass, roots, and organic material extending 150 millimetres beyond your project perimeter to prevent future settling. Mark boundaries with spray paint or stakes, then contact Ontario One Call at least five business days before digging to avoid damaging buried utilities.
Excavate to required depth accounting for your gravel base, bedding sand, and paver thickness. For walkways, dig 200 millimetres deep. Patios need 225 millimetres, while driveways require 250 to 300 millimetres depending on soil conditions. Clay soils demand deeper excavation than sandy or gravelly ground.
Create a gentle slope of 2% away from structures for proper drainage. This equals 6 millimetres of drop per 300 millimetres of distance. Use a laser level or long spirit level with taut string lines to verify slope accuracy across the entire area.
Excavation sequence
Mark project boundaries with stakes and string, adding 150 millimetres on all sides
Contact Ontario One Call and wait for utility location confirmation
Remove all vegetation, topsoil, and organic material within marked area
Excavate to calculated depth using a flat shovel and wheelbarrow
Grade bottom of excavation with 2% slope away from buildings
Compact exposed soil lightly with plate compactor to create firm subgrade
Verify depth and slope with level and measuring tape before proceeding
Pro Tip: Use a laser level or long spirit level with string lines spanning the entire site to maintain consistent slope and catch low spots before adding base material.

Base installation: gravel layer and compaction
A properly compacted gravel base prevents settling and distributes loads evenly. Spread ¾-inch clear stone in a uniform layer 100 to 150 millimetres thick, depending on your project type. Walkways need 100 millimetres, patios require 125 millimetres, and driveways demand 150 millimetres or more for heavy vehicle traffic.
Compact the base to 95% Proctor density using multiple passes with your plate compactor. For bases exceeding 150 millimetres, compact in 75-millimetre lifts rather than all at once to achieve proper density throughout. Each lift should receive at least four passes in different directions.
Check compaction by walking across the surface. Properly compacted stone barely moves underfoot and produces a solid, crunching sound. Loose areas require additional passes until firm.
Base specifications by project type
Project type | Base thickness | Compaction level | Traffic load |
Walkway | 100 mm | 95% Proctor | Foot traffic only |
Patio | 125 mm | 95% Proctor | Furniture, light equipment |
Residential driveway | 150 mm | 95% Proctor | Cars, light trucks |
Commercial driveway | 200 mm | 98% Proctor | Heavy vehicles, frequent use |
Suitable base materials
¾-inch clear stone (most common, excellent drainage)
¾-inch crushed limestone (angular edges lock together well)
Recycled concrete aggregate (environmentally friendly, cost effective)
Dense graded aggregate (less drainage but higher load capacity)
Pro Tip: Lightly moisten gravel with a garden hose before compacting to improve particle bonding and achieve higher density with fewer passes.

Laying pavers: patterns, cutting, and alignment
Pattern selection affects both appearance and structural performance. Herringbone patterns increase load capacity by 30% compared to running bond layouts, making them ideal for driveways. Running bond or basket weave patterns work beautifully for patios and walkways with lighter traffic.
Set string lines parallel to your starting edge to maintain straight rows and consistent spacing. Begin laying from a straight edge or corner, placing pavers tightly together with 2 to 3 millimetre gaps. Check alignment every three rows using your string line and level.
Cut pavers cleanly with a wet saw to reduce chipping, especially for border pieces and curves. Mark cut lines with a pencil, secure the paver firmly, and make smooth, steady passes without forcing the blade. Always wear eye protection and ensure adequate water flow to control dust.
Paver laying sequence
Spread 25 millimetres of bedding sand over compacted base and screed level
Set string lines parallel to starting edge for alignment reference
Begin laying pavers from straight edge or 90-degree corner
Place each paver snugly against neighbours with minimal gaps
Tap gently with rubber mallet to set level, checking with spirit level
Maintain string line alignment, adjusting every third row as needed
Cut border and edge pavers last after field is complete
Check overall levelness across multiple pavers frequently
Tight joints between pavers create structural interlock that distributes loads and prevents individual paver movement. Gaps wider than 5 millimetres weaken this effect and allow excessive joint sand loss.

Joint filling and edge restraint installation
Stabilising joints and edges completes your installation. Sweep polymeric sand across the paver surface, working it into joints with a stiff broom. Make multiple passes in different directions until joints fill flush with paver tops. Compact the surface gently with your plate compactor, using a protective pad to avoid paver damage.
Polymeric sand improves weed resistance by 15% compared to regular sand and creates a semi-rigid joint that prevents insect tunnelling and sand washout. After compacting, sweep away excess sand, then mist the surface lightly with water to activate the polymer binding agents. Avoid heavy watering that washes sand from joints.
Install edge restraints along all perimeter edges using plastic or aluminium units designed for pavers. Position restraints against paver edges and anchor with 250-millimetre spikes driven through pre-drilled holes every 300 millimetres. Backfill behind restraints with soil or gravel for additional support.
Installation steps for joints and edges
Sweep polymeric sand across pavers, filling all joints completely
Compact surface with padded plate compactor to settle sand
Add more sand to joints as needed after first compaction
Compact again and sweep away all excess sand from paver surfaces
Position edge restraints snugly against perimeter pavers
Drive spikes through restraint holes into compacted base every 300 mm
Backfill behind restraints with soil, tamping firmly
Mist joints lightly with water to activate polymeric sand binding
Proper edge restraints prevent perimeter pavers from spreading outward under traffic loads, which causes joint widening and eventual surface failure. Skipping this step increases edge problems significantly.

Common installation mistakes and troubleshooting
Avoiding frequent errors saves time and ensures lasting results. Inadequate base depth causes settling within months as soil compresses under load. Always excavate to full calculated depth and verify before adding base material. Poor compaction creates the same problem, so make multiple compactor passes until the base feels rock solid.
Skipping edge restraints allows perimeter pavers to shift outward, widening joints and destabilising the entire surface. Install restraints on every project regardless of size. Using regular sand instead of polymeric sand invites weed growth, insect nests, and rapid joint sand loss during rain.
Installations without proper edge restraints experience up to 40% more edge failures within the first two years compared to properly restrained projects, leading to costly repairs and reduced lifespan.
Improper cutting with standard circular saws creates rough, chipped edges that look unprofessional and weaken pavers. Invest in wet saw rental for clean cuts every time.
Common issues and corrections
Insufficient base depth: Excavate deeper and add proper base thickness before proceeding
Loose, poorly compacted base: Make additional compactor passes until surface is firm
Missing edge restraints: Install restraints immediately before traffic uses surface
Regular sand in joints: Remove and replace with polymeric sand for durability
Rough paver cuts: Use wet saw with diamond blade for all cutting tasks
Uneven surface after laying: Lift affected pavers, adjust bedding sand, relay and compact
Check for settling by placing a long straightedge across the surface monthly during the first season. Address low spots promptly by lifting pavers, adding bedding sand, and re-levelling.
Understand the durability benefits of interlocking pavers to appreciate the value of proper installation technique.
Installation timeline, safety considerations, and expected outcomes
A typical 400 square foot project takes two to four days depending on your experience level and site complexity. Day one covers excavation and base installation. Day two focuses on paver laying and cutting. Day three handles joint filling and edge restraint installation. Allow extra time for complex patterns or challenging site conditions.
Safety matters throughout the process. Wear leather gloves when handling pavers to prevent cuts and blisters. Use eye protection whenever operating the wet saw or plate compactor. Dust masks reduce silica exposure during cutting. Ear protection prevents hearing damage from compactor noise.
Safety and workflow essentials
Wear gloves, eye protection, and dust mask during all cutting operations
Use ear protection when operating plate compactor for extended periods
Lift pavers using proper technique, bending knees and keeping back straight
Take frequent breaks during compaction and heavy lifting to prevent fatigue
Keep work area clear of tripping hazards like tools and excess materials
Start early in the day during summer to avoid peak heat
Work systematically from one end to the other to maintain quality
Properly installed pavers show no settling after six months and maintain stable, even surfaces for decades. Edges remain firmly in place without spreading or sinking. Weed growth stays minimal thanks to polymeric sand joints. With basic maintenance like sweeping, occasional joint topping, and periodic edge checks, your installation lasts 25 years or more.
Ongoing maintenance involves sweeping debris monthly, inspecting joints annually and adding polymeric sand where needed, checking edge restraints for firmness each spring, and power washing every two to three years to refresh appearance. These simple tasks preserve your investment and keep the surface looking new.
