Introduction

Water is the enemy of a building. In fact, it’s one of the biggest threats to human health, safety, and comfort. It causes mold growth, rusting of structural supports, rotting of wooden structures, and electrical hazards due to poor insulation. Waterproofing is an important part of construction decisions since it helps prevent water damage. This includes waterproofing materials such as concrete and brick or concrete blocks

Question: How does this work?

Waterproofing is accomplished by sealing the cracks and seams of a structure or material with a watertight sealant. The expanding foam is sprayed into the cracks and seams of the walls and ceiling, and then it expands to fill the gaps.

This is how it works:

Waterproofing is accomplished by sealing the cracks and seams of a structure or material with a watertight sealant. The sealant is a flexible material that expands and contracts with the movement of the structure or material. Sealants can be applied as a liquid, spray foam, caulking, or insulation (such as closed-cell spray foam). For example, when John waterproofed his bathroom he used an expanding foam to fill all of the cracks in his wall joints before caulking over them. Now they are completely waterproof!
