Commercial Interlock and Pavers Grimsby

Step 1, Review loads, grading, geotechnical support, drainage, utilities, pattern, units, edges, joints, accessibility, and mockups.

Step 2, Excavate and proof formation, install separation or drainage, and place compacted aggregate layers to surveyed grade.

Step 3, Set curbs and edge restraint, screed uniform bedding, establish lines, and place units without disturbing support.

Step 4, Make clean cuts, compact with protected equipment, fill joints with specified material, and correct settlement or rocking.

Step 5, Verify elevations, drainage, transitions, pattern, joint fill, edges, and protection before traffic and winter maintenance.

Harrowgate builds unit paving as a confined, drained pavement section. Each lift is proofed and compacted, elevations are controlled from the design grades, and the surface is laid and compacted without disturbing the uniform bedding layer beneath it.

Layout, excavation, and proofing. Survey control establishes finished elevations, crossfall, curb lines, and drainage. Existing pavement and unsuitable fill are removed to the required depth. The exposed subgrade is proofed for pumping or yielding areas, and soft zones are undercut and replaced under the geotechnical direction before base material is placed.

Separation and base construction. Geotextile is installed where the design requires separation or reinforcement, with overlaps and turn-ups kept intact. Granular base or open-graded stone is placed in controlled lifts and compacted to the project density. Elevations account for bedding and paver thickness so crews do not use loose bedding to correct base errors.

Drainage and edge restraint. Surface slopes direct runoff to drains, curbs, or approved infiltration areas. Permeable systems use clean open-graded aggregates, underdrains, and overflow connections without fines contamination. Concrete curbs, edge beams, walls, or manufactured restraints are installed firmly enough to resist lateral spread under turning wheels and seasonal movement.

Bedding and laying. Bedding aggregate is screeded to a uniform loose thickness and left uncompacted until pavers are placed. Units are laid from established lines in the approved pattern, blending bundles to distribute colour. Workers operate from the completed surface and do not disturb the screeded bed. Lines and joint widths are checked continuously.

Cuts and fixed-object details. Pavers at curbs, drains, poles, utility covers, steps, and walls are wet-sawn or dust-controlled to produce clean full-depth cuts. Small unstable slivers are avoided by adjusting layout or using approved infill. Covers are set flush with the finished plane and surrounded by restraint that prevents rotation or joint loss.

Jointing and final compaction. The surface receives initial plate compaction with equipment and pads suited to the paver. Approved joint aggregate is swept into dry joints and compacted in repeated passes until full. Permeable joints receive clean specified stone, not polymeric sand. Final review checks grades, rocking units, chipped edges, pattern, cuts, and restraints.

Harrowgate protects completed pavers from tracked soil, concrete slurry, asphalt tack, and construction loads outside the design. Extra matching units are set aside where requested for future utility work. Turnover documents the base and joint materials, permeable maintenance needs, approved deicing and cleaning practices, and areas where snowplow blades require skids or careful adjustment.
