Foundation Contractor

Harrowgate’s package includes survey, excavation interfaces, groundwater control, bearing preparation, mud slabs, formwork, reinforcing, footings, walls, piers, pile caps, grade beams, embeds, anchors, waterstops, concrete placement, curing, stripping, repair, drainage and waterproofing interfaces, backfill, testing, survey, and closeout as defined by the issued documents.

The project’s geotechnical consultant or engineer confirms bearing in accordance with the design and inspection plan. Harrowgate exposes and protects the founding surface, controls water and traffic, provides safe access, documents conditions, and holds cover until review is complete. Unsuitable or disturbed areas are corrected only through issued direction.

Harrowgate uses coordinated anchor plans, rigid templates, independent survey checks, secure supports, and controlled concrete placement. Bolt group location, spacing, projection, elevation, and orientation are checked before and after the pour. Surveyed deviations are reported before connected steel or equipment is altered, avoiding hidden field fixes that transfer problems forward.

Backfill starts after concrete reaches the specified condition, forms and ties are addressed, the wall has required lateral support or bracing, waterproofing and drainage are inspected and protected, and the engineer’s sequencing requirements are satisfied. Harrowgate places fill in controlled lifts and avoids damaging or unbalancing the wall.

Harrowgate diverts surface water, implements approved dewatering, protects excavations from freezing, removes ice and softened material, and uses specified enclosure, heat, insulation, and temperature monitoring for concrete. Groundwater pressure and discharge are managed through the project plan so bearing, concrete, membranes, adjacent assets, and receiving systems remain controlled.

The 2024 Ontario Building Code, structural and geotechnical design, CSA A23.1 and A23.2, CSA A23.3, applicable masonry standards, and project specifications govern the work. Municipal permits and inspection requirements also apply. Harrowgate confirms the issued criteria for each foundation rather than relying on generic dimensions or concrete strength.

Records include bearing reviews, survey checks, pre-pour inspections, reinforcing and embed photographs, concrete mixes and tickets, field tests, cylinder results, curing and temperature logs, anchor surveys, membrane and drainage inspections, backfill tests, non-conformance reviews, and deficiency closeout, organized by grid, element, and pour.
