Cinder block foundation walls are hollow, and can fill up with water. That's why on a french drain system "weep holes" are drilled into the bottom row of the blocks. Without these holes, the block wall can fill up with water and start to deteriorate and erode.
If ignored this process can lead to failure of the foundation wall, requiring restoration.
These are the main, basic steps when restoring a cinder block foundation wall due to water erosion:
- Excavate, Clean and Prep Deteriorated Wall
- Restore Cinder Block Foundation Wall
- Waterproof Foundation Wall
