Bridge Deck


tráfico rodado

TECNOCOAT and DESMOPOL offer perfect waterproofing and protection of concrete structures for civil engineering works. In addition to being certified by the European Standard EN-1504.2 for "Products and systems for the protection and repair of concrete structures", it has recently obtained the ETE certification according to the EOTA "Liquid applied waterproofing system for bridge decks" (16/0680).

In this way, using our pure polyurea or polyurethane system, a total protection of the concrete structures on bridge decks is achieved, as well as the commissioning of the wearing course (asphalt), avoiding the risk of damage, quickly, effi ciently and therefore reducing the costs of execution.

1. Surface preparation

Our finishes for flat roofs designed for vehicle traffic can be applied on a wide range of existing surfaces, typically concrete, using a simple preparation process, and are designed to meet aesthetic demands as well as waterproofing considerations.

2. Primer

A primer resin should be first applied to ensure adhesion to the surface.

3. Waterproofing membrane

The TECNOCOAT waterproof membrane is applied directly over the primer resin.

4. Primer + Silica Sand

Optionally, apply a thin layer of PRIMER PU-1000 polyurethane resin and lightly sprinkle the aggregate over the surface while it is still wet. This forms an additional layer of protection.
