When our team comes to your home to install an exterior waterproofing solution, their first step will be to dig down to expose the trouble areas on your foundation wall, clean the wall, grind out any cracks and open them into a “V” shape. We’ll apply hydraulic cement to the cracks (the cement sticks better if the crack is opened into a “V” shape), or, in the case of leaks through cinder blocks in the foundation, apply a cement mix to the entire wall.

Aqua block is next. This a rubberized tar, or foundation. Then we’ll apply  yellow jacket, which is a fibreglass mesh, that is squeezed into the aqua block. Then another coat of aqua block is applied (kind of like a sandwich – aqua block is the bread, and yellow jacket is the meat). On top of that our waterproofing contractors will apply six millimetres of poly, that sticks to the aqua block. A rubber membrane is also applied to the wall, so water can drop down into the weeping tile.

We’ll always replace the weeping tile system in any excavation work that we do. Weeping tile is the drainage system installed when your home was built, to re-direct water away from your foundation. Any leak between your home’s footing and the concrete foundation is taken care of by the weeping tile system.

Bottom line – as you can see, exterior waterproofing is the most complete and foolproof method of sealing your basement from water leaks or flooding.
