Grout Injection

Grout injection is a specialized repair technique that fills voids, stabilizes structures, and waterproofs masonry from the inside out—solving hidden problems in Ontario's aging brick buildings. This process involves pumping specially formulated grout into cracks, hollow spaces, or deteriorated cores under controlled pressure, consolidating loose material and restoring structural integrity. Applications range from filling abandoned chimney cavities to stabilizing multi-wythe brick walls where internal mortar has deteriorated. Modern injection grouts include epoxy for structural repairs, polyurethane for waterproofing, and cementitious grouts for large void filling. The technique requires precise pressure control and proper port placement to ensure complete filling without damaging surrounding masonry. Fix My Brick uses grout injection to save walls that would otherwise require demolition, often completing repairs with minimal disruption to building use. This cost-effective solution can restore 90% of original strength while preventing water infiltration and further deterioration.
