The best repair available is a true high pressure polyurethane injection completed with our ports. We never use plastic ports and low pressure injection or epoxy.

Because we use steel ports, our repairs completely fill the crack from inside to outside.

Fixed crack in basement. Very professional and detailed. Communication was excellent. I would call them again and recommend them to friends and family.

Quick, Professional, Quality Service

We moved into our new house and within a month had a leak in our basement. We called Accurate Construction and they were quick to respond. They explained everything they were going to do and why each step was necessary. It's been 8 months since the repair and we've had no problems. Thank you Accurate Construction. We would recommend them in a heartbeat!

My Mum had an emergency situation with water coming through the walls. From the moment I spoke to Jason, I felt that he would take care of everything in the most efficient, knowledgeable and timely way. He and his team, were amazing!! I cannot speak highly enough about the service and we would recommend them to anyone who asked. We are so grateful for his honest and expert service!
