A waterproofing membrane is a specialized layer of material that is designed to protect a surface from water damage or leakage. This material is typically installed on surfaces that are prone to water exposure, such as roofs, foundations, underground structures, and outdoor decks. The membrane is made of a variety of materials, including rubber, asphalt, and polyurethane, and can be applied in liquid or sheet form. The membrane's main function is to create a barrier between the surface and any water that may come into contact with it, thereby preventing any water from seeping through and causing damage.

Waterproofing is necessary in situations where there are signs of water damage. These signs may include peeling or bubbling paint on the walls or ceiling, indicating that moisture has penetrated the surface. Drummy-sounding tiles, which sound hollow when tapped, may also indicate water damage underneath. Water stains on the ceiling can be a tell-tale sign that water has leaked through the roof or plumbing. Black mould growth on grout and tiles can be harmful to your health and is often caused by excess moisture. Finally, a persistent smell or a musty odour in the bathroom may be another indication of water damage. In such cases, it is essential to take action to prevent further damage to your property and ensure the safety and health of those living or working in the affected area.
