Area of expertise

Waterproofing

A technical area with different solutions, chosen according to the substrate, the source of the leak and the exposure.

Solutions

There is no universal product.

The waterproofing solution is defined after assessing the substrate, the source of the leak, the exposure and how the area is used.

Joints, flashings and detailing

Many leak problems sit at junctions and detailing points of the building.

  • Expansion joints
  • Wall/floor junctions
  • Drains
  • Parapets
  • Flashings
  • Pipe penetrations
  • Skylights
  • Other critical points

Waterproofing systems

The systems we use.

We choose the system after assessing each intervention. None is best for every case.

01

Bituminous membranes

Sheet systems for horizontal surfaces and flat roofs.

02

Liquid membranes

Continuous application, suited to geometries with many junctions.

03

Polyurethane systems

Continuous coatings with high elasticity.

04

Waterproof and elastic coatings

Protection of exposed surfaces and external walls.

05

Joint sealing and treatment

Correction of joints, flashings and junctions.

06

Water-repellent treatment

When technically indicated, to reduce water absorption of the substrate.

Do you have a leak?

Start with the diagnosis. We identify the source before proposing the system.
