— FOUNDATION REPAIR
Core-Fill for Foundation Repair: Sudbury & North Bay
Core-Fill is defined as filling your foundation block cavity with concrete grout and reinforced with rebar to form a solid, poured foundation wall.
— WATERPROOFING & CRACK PREVENTION
What is Core-Fill?
Water gets into the block cavity, typically through foundation cracks, and this water will deteriorate your blocks from inside out.
Core-Fill removes the water, eliminates the void, and solidifies the block — all with a waterproof concrete grout. This procedure comes with a 25-year waterproof and foundation crack warranty.
