Cementitious Waterproofing

Cementitious waterproofing is a popular choice for homes and offices. It consists of a mixture of cement, sand, and a waterproofing additive.

Liquid Waterproofing Membranes

Compared to its predecessor, liquid waterproofing membrane is a better option for bathroom waterproofing. This coating can be applied using a roller, brush, or spray, allowing for easy coverage of complex shapes and corners. Liquid membranes are available in water-based and solvent-based formulations. With excellent flexibility, these coverings are ideal for areas prone to structural shifts. However, water-based and solvent-based membranes depends on factors like ventilation, environmental concerns, and the type of substrate.

Sheet Membranes

Sheet membranes, made from materials like PVC, CPE, or bitumen, are applied as thin coverings on bathroom walls and floors. Sheet membranes are known for their durability and reliability, making them suitable for high-traffic or moisture-prone areas. The installation process is more labor-intensive and costly (special adhesives and sealants), but the results are worth the effort.

Polyethylene Membranes

Polyethylene membranes, used in conjunction with other waterproofing methods, are excellent at preventing moisture penetration. These plastic sheets are installed beneath the tiles or other surface materials to create an additional layer of protection. Polyethylene membranes are lightweight, easy to install, and act as a reliable defense against water damage. They are excellent for washrooms with tiled surfaces. Moreover, these coverings can be used in combination with other waterproofing processes.

Waterproofing Paints

Waterproofing paint is a cost-effective solution for bathroom walls and ceilings. It is optimal for bathrooms with limited exposure to moisture. Vice versa, it will require regular maintenance and reapplication if the area is moisture-filled. Waterproofing paint should be considered as a supplementary measure rather than the primary method of bathroom waterproofing.
