Step 1, establish pavement demand. Harrowgate checks geotechnical recommendations, vehicle classes, fire and loading routes, pavement details, grading, drainage, joints, structures, curbs, lighting bases, accessible routes, testing, and phasing.

Step 2, build uniform support. Unsuitable subgrade is corrected, granular subbase and base are placed in controlled lifts, and the platform is proofed for stability, density, grade, and drainage. Utility trenches receive particular attention because differential settlement often follows their alignment.

Step 3, set panels and load transfer. Forms or slipform controls, dowel baskets, tie bars, reinforcement, isolation material, drains, and structures are installed to the joint plan. Re-entrant corners and pavement transitions receive the specified detailing.

Step 4, place and texture. Concrete supply and paving width are planned for continuity. Material is consolidated around dowels and edges, struck to grade, finished without trapping water, and textured for vehicle traction. Evaporation and temperature are monitored.

Step 5, cure, saw, seal, and phase opening. Curing begins immediately and sawcuts are completed before random cracking. Joint reservoirs and sealant follow the specification. Traffic opens only after the required strength, and markings and wheel stops are installed without damaging young pavement.

We strip unsuitable material, proof the subgrade, correct soft zones, and place specified granular base in compacted lifts. Utility trenches and catchbasin excavations receive added attention because settlement at these interfaces creates ponding and cracked slabs. Fine grading establishes uniform slab thickness and designed drainage. Forms, stringline, or machine controls are set from survey benchmarks and checked against curb, inlet, building, and roadway elevations.

Dowel baskets, tie bars, isolation joints, thickened edges, utility boxouts, light-base interfaces, and construction-joint assemblies are secured before placement. Concrete is delivered to the specified CSA exposure class for freezing, thawing, and de-icing salts. We place by slipform or fixed forms depending on geometry, strike the surface to profile, consolidate edges and dowel zones, and produce the specified broom or tine texture without tearing the paste.

Contraction joints are sawed to the approved pattern as soon as the concrete can hold a clean cut. Intersections, re-entrant corners, islands, drains, and changes in width receive a planned joint response rather than improvised short cuts. Curing compound or another specified method is applied at the required uniform rate, including exposed edges after form removal. Concrete is protected from freezing, rapid drying, rain, construction traffic, and de-icing chemicals during early service.

Traffic opening follows achieved strength and the project requirement. Harrowgate phases barriers and signage so businesses, emergency routes, and construction deliveries use only released areas. Joint sealing, pavement markings, wheel stops, bollards, and landscape interfaces proceed after cure and preparation criteria are met. Final review checks drainage, ride, texture, joint condition, transitions, and surface defects before full opening.
