Injection |
|
Tim is starting the injection process. |
|
|
|
|
|
|
|
|
|
|
|
Material |
|
The low viscosity liquid urethane is being injected. The material is leaking out of the crack prior to reacting. |
|
|
|
|
|
|
|
|
|
|
Reaction |
|
The urethane is reacting with the water and foaming. The flow of water has now stopped. |
|
|
|
|
|
|
|
|
|
|
More. |
|
The injection process continues. |
|
|
|
|

|
|
Almost done. |
|
The crack is now filled. |

Beam pocket |
|
Beam pockets, where the support beam rests on the foundation wall, are a source of water leaks. |
|
|
|
|
|
|
|
|
|
|
|
Beam Pocket |
|
Injection of urethane on both sides of the pocket seals off any water infiltration. |
