Insulation and waterproofing for roofs and terraces

Solutions for irregular surfaces, slopes and difficult junctions. We combine the right application method with careful preparation to protect against water and improve roof insulation.

Insulation applied to an irregular roof

Irregular surfaces: details make the difference

Corrugations, changes of slope, corners and service penetrations make uniform protection harder to achieve. Cuts and adjustments around these details need attention: a discontinuity can allow water ingress or reduce insulation performance.

Sprayed systems and liquid membranes follow the substrate’s geometry. They can cover complex shapes, while every joint, connection and drain still needs detailing compatible with the full system.

A technique for each need

Polyurethane foam applied to a roof

Spray polyurethane foam

Expands on accessible, compatible surfaces to form insulation following their profile. It helps reduce heat transfer and energy loss. We select formulation, thickness and any exterior protection required; foam alone is not a complete waterproofing system.

Waterproofing with polyurethane and polyurea membranes

Polyurethane and polyurea membranes

Form continuous waterproof protection on a prepared substrate. Liquid application accommodates corners and junctions; hot-sprayed polyurea can cover suitable areas quickly. Primer, reinforcement and finish depend on the system, sunlight and expected traffic.

Efficient application on a prepared substrate

Following the surface can reduce cutting and fitting of preformed materials. Efficient work still begins with repairs and checks of cleanliness, moisture and adhesion. Weather conditions, thickness and waiting times between coats and before use must be respected.

Drains, upstands, joints and penetrations are detailed before the main area is completed. A membrane can accommodate movement within its limits, but cannot by itself repair structural cracks or correct falls that retain water. Clear drainage remains essential.

Benefits for your roof

  • Treatment of profiles and difficult details without relying on fixed-shape pieces.
  • Improved insulation or waterproofing continuity, depending on the system.
  • Potential to refurbish existing roofs where condition and compatibility allow.
  • Finishes adapted to regularly used terraces or maintenance-only roofs.
