For most home, waterproofing the basement from the inside will be the best option. This is because it’s more cost-effective and less disruptive than exterior excavation.

We’ll do this by digging a small trench along the perimeter of the basement floor, and we’ll install a drain and sump pump to move water out.

We’ll normally use Polyurethane foam injections to fill cracks that pose no structural risk to the foundation. Polyurethane provides an extremely good solution for sealing cracks in your foundation. For cracks that are bigger we could use epoxy injections and different kinds of sealants.

These techniques will effectively prevent water and insect from getting inside your basement.
