  • Water leaks through cracks in concrete causing more severe damage than the cracks. Corrosion, carbonation freeze/thaw damage, even structural failure can be attributed to cracks and water.
  • Crack Injection works in both wet and dry conditions. We inject non-toxic, polymer resin to fill the entire crack - even microscopic fissures to stop the leak fast. And permanently. We even stop flowing water.
  • Our polymer resin is permanently flexible and therefore will not re-crack.

Our Employees have a lot of experience and hold all the relevant training, including confined spaces
