Frequently asked questions

  • How to prepare for waterproofing?

    First step before waterproofing an area is to clean the surface to remove dust, grease, rust, paint and any other material which may affect the adhesion of coatings. After cleaning the surfaces, verify the dectivity and if necessary fix it in order to avoid water stagnation. Lastly, prepare the surface (the preparation process will depend on the type of surface).

  • How long can waterproofing last?

    A properly installed waterproofing system should last you anytime between 10 and 15 years. On the contrary, a poorly installed waterproofing system can cause water leakages almost immediately after it meets water, avoid such waterproofing mistakes. Roof waterproofing can last longer, especially torch on waterproofing.

  • Can you repair waterproofing?

    Depending on the extent of damage on your waterproofing membrane and the age of it, you can choose between simple patches or a complete replacement.

  • Which method of waterproofing is best for flat roofs?

    The most common way of waterproofing a flat roof is by torch on waterproofing.

  • Which membrane is best used for waterproofing flat roofs?

    Reinforced bitumen membranes are the most commonly used material to waterproof flat roofs on residential properties. The process involves laying down two or three layers of the material across the full surface of the roof. These are then bonded together by hot bitumen.
