Exterior Crack Repair
Depending on the age of your poured concrete foundation and the condition of the foundation or basement wall crack, we may recommend an Exterior Crack Repair as the best method for waterproofing. This treatment requires excavation down to the weeping tile so that we can also check the weepers. Of course this only tells us their condition at that location. If a weeper problem is found, a Weeper Flush may be required. In some cases a video scoping is required for visual confirmation.
If the problem is confirmed to be plugged weepers, flushing is only a temporary fix. A permanent fix requires that the problem that caused the tile pluggage to be identified and corrected in order to prevent future blockages. Click here to learn more about weeping tiles
Very few concrete crack repairs fail immediately. It is the long-term creep and fatigue of material injected in concrete cracks that can fail over time due to foundation movement. By cross-stitching concrete crack repairs with carbon fibre staples, this creep is eliminated and the long-term performance of the repair is guaranteed.
- The area is first excavated, usually by hand, down to expose the weeping tile.
- Weeping tile inspection is performed.
- The cracked is identified.
- A Bentonite Mastic is applied
- A Flood Boot is then installed
- An Air-Gap Membrane is applied as an additional waterproofing shield and to relieve hydrostatic pressure
- Drainage Stone is then added
- Native soil backfill is replaced and compacted.
