Icopal Enviroflex Reinforcing Fabric

Enviroflex™ Reinforcing Fabric is a polyester based reinforcing fleece intended to be used as the reinforcing layer within the Enviroflex™ liquid waterproofing system.

The fleece, available in a number of widths in a standard 135 gsm weight grade, is embedded into the Enviroflex™ liquid applied waterproofing coating in a ‘wet-on-wet’ application

The Enviroflex™ system is suitable for use as an exposed membrane in both new and refurbishment projects, particularly where traditional methods of waterproofing may prove difficult.

It is intended for use where limited foot traffic is anticipated, but may also be used in conjunction with the Enviroflex™ Walkway System where clear designation of anti-skid passageways is required.

Surface Preparation

Ensure the substrate is sound, clean, dry and free of frost, dust and debris, and any material which would hinder adhesion. Residual moisture in concrete substrates must not exceed 5% in the upper 2 cm.

Application Conditions

Apply only when atmospheric and substrate temperatures are greater than 5 °C. The surface of the substrate should be clean and dry and must be 3 °C above the dew point. If the surface is below or at dew point temperature then moisture can form at the surface and affect coating adhesion and curing.

Personal Protective Equipment (PPE) should be worn.

Coverage Rates

The Enviroflex™ System is applied ‘wet-on-wet’ allowing full membrane application in a single process.

The total application rate of Enviroflex™ Liquid Waterproof Coating should be approximately 1.2 to 1.4 L/m2, depending on porosity and texture of substrate.

Application Method

Prior to the application of the Enviroflex™ Liquid Waterproof Coating, prime the substrate with an appropriate Enviroflex™ Acrylic Primer or Enviroflex™ EP1 Primer, and allow to cure.

Apply approximately 1/3rd of the Enviroflex™ Liquid Waterproof Coating above the primed substrate as the base layer using a brush or roller.

Immediately apply the Enviroflex™ Reinforcing Fabric into the base layer and roll the surface with a perlon roller, eliminating potential air bubbles. Overlaps in the reinforcing fabric should be a minimum 75mm.

Apply immediately the remaining 2/3rd of Enviroflex™ Liquid Waterproof Coating above the reinforcing fabric as the top layer.

Roll out evenly until complete saturation is achieved. Ensure the overlap areas (above and below the overlapping fabric) are fully saturated to maintain continuity of the waterproofing system.

See Enviroflex™ Liquid Waterproof Coating product information sheet for coverage rates and installation guidance.
