At Allied Water Services, we specialize in foundation crack injection and crawl space waterproofing that permanently seal non-structural cracks and stop water intrusion at the source. This process is ideal for cinderblock or poured-concrete foundations, particularly in crawl spaces where even minor cracks can lead to moisture, mold, and long-term structural wear. Our three-step crack sealing procedure ensures reliable, lasting results: ⚙️ Crack Sealing Procedure 1. Surface Preparation The affected area is thoroughly cleaned and prepared to ensure maximum adhesion and material performance. Proper surface prep allows the repair materials to bond effectively for long-term durability. 2. Epoxy and Port Installation A structural epoxy is applied along the crack surface, and injection ports are installed across its entire length to allow controlled and even distribution of sealant during the injection process. 3. Polyurethane Injection High-velocity polyurethane is then injected through each port, filling all voids deep within the wall. As it expands, it creates a flexible, watertight seal that adapts to minor foundation movement while permanently stopping leaks. 💪 Why Choose Allied Water Services - Experts in crawl space crack repair and waterproofing - Use of industrial-grade epoxy and polyurethane for lasting protection - Clean, efficient installations with full restoration after work completion Stop water where it starts.
