Introduction to Foundation Waterproofing

Foundation waterproofing is the process of preventing water from penetrating the below-grade portion of a building. Without proper waterproofing, foundations are susceptible to cracks, mold growth, and structural deterioration.

Modern construction demands high-performance waterproofing products that are long-lasting, eco-friendly, and easy to apply. In 2025, the market is full of innovative products that use advanced chemistry to protect buildings more effectively than ever before.
