Concrete Finishing

Floating levels ridges, fills small voids, embeds coarse aggregate, and prepares the surface after strikeoff. Trowelling follows on specified interior floors to compact and densify the paste through progressively tighter passes. Exterior air-entrained concrete generally receives a float and textured finish rather than aggressive hard trowelling.

Working bleed water into the surface raises the local water-to-cementing-material ratio and can trap water or air beneath a closed layer. The result can be dusting, low abrasion resistance, blisters, or delamination. Harrowgate waits for bleeding to end and bases each pass on concrete response across the pour.

A transverse broom or specified tine texture commonly provides traction and drainage without deep grooves that impede cleaning or snow removal. The exact texture depends on slope, vehicles, pedestrians, exposure, and maintenance. Harrowgate establishes the ramp profile first, then applies a consistent texture at the correct concrete set.

Concrete is placed consistently, struck to elevation, floated after bleeding, then machine trowelled in multiple passes as it gains strength. Blade angle and timing increase gradually. Harrowgate synchronizes edges, applies specified hardener or densifier-compatible cure, cuts joints within the window, and protects the floor from premature traffic and contamination.

The coating, adhesive, densifier, or polishing system determines compatibility. Some curing compounds interfere with bond or colour and require removal. Harrowgate coordinates the final assembly before pouring and uses an approved wet, sheet, or compound cure, then completes the specified mechanical preparation and moisture checks before treatment.

Cuts made too late, insufficient depth, wide joint spacing, re-entrant corners, high shrinkage, rapid drying, restraint, base movement, and thickened transitions can let stress choose another path. Harrowgate follows the engineered joint plan, starts cutting within the actual window, adds planned details at stress concentrations, and maintains uniform curing.

Some high spots, texture issues, surface contamination, and localized defects can be ground, profiled, patched, or overlaid. Low areas, delamination, scaling, and tolerance failures require investigation before a method is selected. Harrowgate surveys and sounds the surface, identifies the cause, and executes an engineer or finish-consultant approved correction.
