For structural repairs. we use a low-viscosity, rapid-setting epoxy adhesive often with an engineered pressure treated wood wall. Structural repairs very in pricing depending on degree the structural integrity compromised. When required I prefer to use outside structural engineers to avoid conflict of interest.
On non-structural repairs we use single-component, water activated, hydrophilic, low viscosity polyurethane injection resin. It's a closed cell, water tight foam that can be used to seal actively leaking joints/cracks in concrete structures - it expands to fill the path with an elastic deal that stops water but allows crack movement to protect against stress transfers.
We believe in the high quality of our work - that is why we are happy to provide all of our clients with a 100% satisfaction guarantee and a ten year transferrable warranty on all foundation repairs.
