At Helitech, we use a specially formulated epoxy injection that permanently restores the structural strength to cracked concrete. In addition to being easy to administer, these injections are effective in a wide range of areas – from concrete basements to foundation walls to concrete structures.
Some foundation contractors will recommend a polyurethane injection instead of epoxy. These might make more sense is there is concern about material leaking out the back of a crack. These fast-setting foams begin to harden and foam within minutes, effectively reducing the chance that materials will flow out of the injected crack.
At Helitech, we’ll employ epoxy injections to create a sealant on some cracks, but other more serious ones might require extensive work. A professional may fill the crack, install carbon fiber material to help protect the foundation’s structural integrity and install benchmarks to monitor further movement or settlement.
You should note that if you have horizontal cracks or severe bowing walls, your home improvement project might need more attention than simple crack repairs.
