When to Use Waterproofing Materials in United States of America USAn Construction

Essential Areas Requiring Water Protection

Waterproofing is the process of making an object or structure impervious to water. While it adds a cost layer to construction, it is a non-negotiable step in high-risk areas to prevent structural decay, mold, and damp-related health issues.

Critical Areas for Waterproofing

• **Wet Areas (Bathrooms/Showers):** The floor slab and the lower section of the walls in all bathrooms and kitchen areas must be treated with a liquid waterproofing membrane before tiling. This prevents seepage into lower floors or surrounding walls.
• **Foundations (Below Grade):** The external surface of the foundation walls (below ground level) should be treated with a damp-proofing membrane or bituminous coating. This prevents capillary rise (moisture wicking up) and lateral damp penetration from the soil.
• **Flat Roofs:** Any roof that does not shed water quickly (especially reinforced concrete flat roofs) requires heavy-duty waterproofing materials (e.g., torch-on membranes) to prevent leakage during heavy rainfall.
