Although concrete is water-resistant, it is not waterproof in its original state. It is porous and permeable and tends to crack under pressure. Even then, some of the most important structures in a building, like the foundation and pillars, are made from concrete. Thus, concrete waterproofing is important to keep water out and preserve the overall strength of the home.

Let’ take the foundation, for instance. The vast majority of foundation problems are caused by water penetration. As water penetrates the foundation, it causes cracks and fissures to develop. The soil around the foundation can also swell or become lose. Consequently, the dampness typically causes mould to grow in below-ground interior spaces like the basement, making them unpleasant to stay in.

These are not easy problems to solve. A foundation problem is the worst thing that can happen to a home since it is literally what the house stands on. In a residential building, issues with the foundation can ruin vital equipment and disrupt workflow, leading to wasted time and money.

Similarly, in a residential building, such issues can damage finishes and furnishings, and if left unchecked for long enough, the structure itself goes down. This is without mentioning the expensive costs that accompany foundation repairs in buildings. Thus, keeping water from reaching the foundation and seeping into the concrete is essential to the structure’s durability.

This is typically done through a combination of drainage systems that direct water away from the foundation and waterproof the concrete.

Other structures that require concrete waterproofing include swimming pools, concrete water tanks, and concrete roofs.
