The residential waterproofing market is huge and can be quite the cash cow for contractors who enjoy tending to a constant stream of smaller jobs. Let's review common residential waterproofing issues and the Alchemy-Spetec products you can use to address them.

Leaks - Concrete Walls

This is the most common problem in the residential market, most often found in basements. You can repair leaks in poured concrete and pre-cast walls with Alchemy-Spetec’s F400. This hydrophobic grout will not shrink after application, during spells of dryer weather. In addition, this product has a thin composition and can penetrate fine, hairline cracks. The application process involves injecting the cracks with the resin, which then reacts with the leaking water to form a durable watertight seal. 

Leaks - Non-Concrete Walls

Many basement walls are made of brick, block, stone or rubble. Leaks in these types of walls require a process called curtain wall grouting (a.k.a. “through-wall” grouting). Curtain wall grouting involves drilling holes in a grid pattern and injecting Alchemy-Spetec’s AP 700 through the wall to form a waterproof curtain on the other side.

Leaks - Floor/Wall Intersection

Sometimes builders will neglect to use a leak seal product at this critical joint in the structure where the floor and wall meet. Even if they do seal these joints initially, with a mediocre product there will be failure over time. When faced with these types of issues, you can inject F400 for a lasting, durable repair. This application process is similar to crack injection for leaks in concrete walls as described above.
