EWS1000 Res-Tec Flexitec 2020 System


This is an assessment of Res-Tec Flexitec 2020 System, a multi-surface GRP roofing system used for waterproofing of roofs, balconies and walkways. The Flexitec 2020 System can be applied to almost any roof surface including felt, asphalt, concrete, GRP, PVC single ply, OSB3 TG4 and metals.

The system is primarily used to overlay existing roofs and consists of Flexitec Primer (where required), 1st Coat Flexitec 2020 Resin with Fiberglass CSM Reinforcement (10 year system) and 2nd Coat Flexitec 2020 Resin (20 year system).

Res-Tec will provide a detailed application manual and offer certified training to Installers.

A 10 or 20 year guarantee between Res-Tec and the installer is provided, subject to the system used and the terms and conditions.

The Flexitec 2020 System relies on other construction products, materials and components to form a complete roof, balcony or walkway; overall compliance will therefore be dependent on final specification.
