Exterior Basement Waterproofing

Keeping your basement and foundation safe from moisture and water can be quite an extensive project. There are so many features you can implement that will keep water away – but which one is right for you? Let’s talk a little bit about exterior basement waterproofing.

What About Damp Proofing?

You might be wondering why you should go through as extensive a fix as waterproofing if you could just damp proof. The thing is, both are very different from each other. They both have to do with sealing your basement and protecting your foundation, sure. The difference is that damp proofing is to protect your foundation from soil moisture. Waterproofing will protect it from running water and lead water away from your home.

So, damp proofing has its place. It’s up to you to determine which one is right for your situation. Waterproofing is usually used for completely underground basements on level ground. This is where water will usually collect and sit. Waterproofing will keep the water from collecting in the basement and will, instead, redirect it.

How Is It Done?

Waterproofing is done with multiple elements.

  1. The first step is making sure any cracks in your foundation have been fixed prior. Once the waterproofing is done, you won’t have access to them, so they have to be fixed first.
  2. Then, the drainage system is put in place. This includes weeping tiles. Weeping tiles are perforated drain pipes. The weeping tiles will collect water and divert it away from the house. It will either drain into a city storm drain or into a sump pump.
  3. Next, there’s the fluid membrane that coats the exterior of the basement wall. This is necessary so that the solid membrane will have a flat surface to adhere to. It fills in all the crevices and rough patches so that there aren’t any weak spots in the membrane.
  4. After that, your foundation is ready for the sheet membrane. This goes on top of the fluid membrane. It’s a heavy duty plastic sheeting that water won’t be able to get through. Our team will ensure each seam between membranes is sufficiently sealed to ensure there aren’t vulnerabilities.
