Basement Crack Repair Toronto
Do you have a poured concrete foundation? Here’s how to fix it.
- When a crack is evident, it can readily be repaired from the outside by hand digging 2.5 to 3′ on either side and right down to the footing or weeping tile, creating a hole measuring about 5′ across by 6′ deep.
- Before digging, place a tarp on the ground in front of the measured area. The tarp is used to hold all the dirt from the hole you are about to dig. It’s important to keep things as tidy as possible.
- Once you’ve exposed the wall, it is necessary to clean and dry the entire area. This is done with water and a wire brush. All masonry must be primed before hydro shield can be applied.
- Hydro Shield, the rubberized membrane, is applied to the complete opening of the wall with a trowel.
- After membrane has been applied, drainage board is installed in front of entire repaired area.
- The drainage board is applied from above grade, right down to the weeping tile, preventing water pressure from building up in front of the repaired area.
- Cover up weeping tile 1′ deep with ¾” gravel.
- The hole is backfilled by hand.
- A hand compactor is used, at the end, to level the dirt for a more smooth even finish.
If you have a Concrete Block Foundation, here is how to fix it.
- When repairing a concrete block foundation, apply the same steps above. The only difference is that you must make your opening 4′ to 5′ on either side of the leaking area, as cracking often occurs horizontally.
