Terrace Waterproofing

Waterproofing is a critical aspect of any terrace — whether it’s accessible or not, and whether it covers a heated room or a garage.
Poor waterproofing can lead to leaks, mould, and even structural damage.

At Prestige Habitat Roofwork, we operate in Zaventem, as well as Sterrebeek, Kraainem, Wezembeek-Oppem, Evere, Woluwe, Auderghem, and nearby areas, to inspect, treat, or completely replace the waterproofing of your terraces, balconies, and flat roofs.

When Should You Redo Your Terrace Waterproofing?

Watch out for these warning signs:

  • Moisture marks or stains on the ceiling below

  • Swollen coatings or tiles coming loose

  • Leaks appearing after rainfall

  • Vegetation growing on the terrace surface

  • Waterproofing system over 20 years old

An early diagnosis can often prevent the need for a full renovation.
We’re here to help you find the most suitable solution based on your terrace layout and your budget

Our Waterproofing Solutions

We work with all modern waterproofing systems, each backed by a 10-year warranty:

  • Bituminous membranes (SBS, APP) applied with heat

  • Liquid waterproofing (PMMA or polyurethane) – ideal for complex shapes

  • EPDM: highly durable synthetic rubber, resistant to UV and extreme temperatures

  • Inverted insulation systems – for accessible or non-accessible flat roofs

  • Under-tile waterproofing (for terraces with tiles or slabs on pedestals)

Each project begins with a detailed assessment of the surface, slope, drainage, and critical points such as parapets, upstands, and joints.
