Waterproofing FAQ's
If you’re considering a basement waterproofing project or require a concrete waterproofing repair, we hope that our list of frequently asked questions will help make the process of beginning to deal with structural repair problems as simple as possible.
- What is tanking?
- The term ‘tanking’ is often used to refer to waterproofing that takes place below ground level.
- How do cavity membranes work?
- Cavity drain membranes allow water to continue to penetrate a structure but control and then divert it to a suitable drainage point, sometimes using a mechanical pump. The dimpled profile of the membrane equalises water pressure and the air gap in the cavity increases the thermal properties and reduces the likelihood of condensation. Drying time is minimal as the membrane is usually dry lined, allowing for quick completion of decorations and finishes.
- What about cementitious coatings?
- Cementitious coatings create a dry environment by introducing a physical barrier to water entering a basement area. When cementitious waterproofing systems are used, which can either be layered renders or slurry coatings, the correct preparation of the substrate is critical. Water stops or PU Resins can be injected to stem the water flow. Layered render systems are then applied to achieve degrees of resistance to water pressure.
