Revinex® Flex System

Revinex® Flex System is a multi-purpose cementitious waterproofing system designed for a wide range of construction applications, including basements, wet areas, terraces, and water-retaining structures. Its adaptable formulation allows different system build-ups to meet specific project performance requirements.

Suitable Applications

▪ Basements, foundations, and underground structures requiring resistance to water pressure
▪ Water tanks, retaining walls, and shafts exposed to hydrostatic pressure
▪ Wet areas such as bathrooms, kitchens, balconies, and terraces (under-tile waterproofing)
▪ Swimming pools and water-retaining structures
▪ Exterior walls and surfaces to be backfilled
▪ Exposed or demanding waterproofing areas when enhanced flexibility or UV resistance is required

Description

Multi-Purpose Cementitious Waterproofing System for Versatile Applications

Revinex® Flex System is a high-performance, cementitious waterproofing system developed to provide reliable protection across a wide range of construction applications. It is designed as a modular system, where the base cementitious component can be combined with different liquid components to achieve varying levels of flexibility, adhesion, and durability depending on project requirements.

The system can be configured into multiple waterproofing solutions — from economical one-component applications to highly flexible, reinforced systems suitable for demanding environments such as terraces, swimming pools, and exposed surfaces.

At Everkast, this system is recommended for projects requiring adaptable waterproofing solutions, particularly where different areas of the same project demand different performance characteristics — such as basements, wet areas, and external structures.

Revinex® Flex System forms a durable, moisture-resistant barrier that protects concrete and masonry substrates from water ingress, including both positive and negative hydrostatic pressure conditions. This makes it especially suitable for underground structures, foundations, and water-retaining applications.

Its excellent adhesion to a wide range of substrates — including concrete, stone, bricks, and ceramics — ensures strong bonding and long-term performance. The system also offers crack-bridging capability and water vapour permeability, allowing the substrate to breathe while maintaining waterproofing integrity.

Depending on the selected system build-up, Revinex® Flex can deliver:

  • High flexibility for movement-prone surfaces
  • Resistance to UV exposure for external applications
  • Enhanced resistance to hydrostatic pressure for below-ground works

This versatility makes it a reliable choice for both new construction and refurbishment projects across residential, commercial, and industrial environments.
