Information About The Images Below Of An ICF Foundation Leak Repair
- This foundation was not sealed on the outside and had a large amount of honeycomb.
- We filled the honeycomb with a hydraulic cement.
- Ports were added with Epoxy to allow for injection of Urethane.
- The small plastic ports were used to inject the Urethane foam into the foundation.
- The foam running down the wall is the urethane expanding.
- A water test should be done to verify that all problem areas have been addressed.
