Application

Cold Applied waterproofing systems particularly suitable for all areas that include joints or that are highly susceptible to cracking including:

  • New Build projects.
  • Structural waterproofing.
  • Inverted roof build ups.
  • Podium decks.
  • Balconies.
  • Refurbishment projects.

Description

A PMMA based, crack-bridging and joint-bridging waterproofing system that is able to withstand mechanical stresses. The waterproofing system's liquid application and high bonding strength on almost any substrate also allow breakthroughs and upstands to be integrated securely and seamlessly. These properties make the system a cost-effective solution for car parks and balconies, especially for refurbishment projects.


System components:

  • Wecryl R 230 - Waterproofing resin.
  • Wecryl R 230 thix - Waterproofing resin.
  • Wecryl R 230 TT - Waterproofing resin.
  • Weplus Fleece - Polyester reinforcement fleece.
  • Wecryl 112 - Resin primer.
  • Wecryl 176 - Resin primer.
  • Wekat Catalyst - Polymethyl methacrylate based catalyst.


Features and benefits:

  • Easy to apply.
  • Fast curing time.
  • Good adhesion on absorbent substrates.
  • Hydrolysis and alkali resistant.
  • Solvent-free.
  • Highly flexible and crack-bridging even at extreme sub-zero temperatures.
  • Fully bonded to the substrate, therefore no flow paths for water under the membrane.

Preparation

Wecryl 176 Primer.

Guidance for specification option:

  • Two-component, fast-reactive/ fast-curing PMMA-based (polymethyl methacrylate) resin primer.
  • Used for the pre-treatment (primer and barrier) of slightly absorbent mineral and timber substrates (concrete, screed, wood).
  • Available in white or clear (unpigmented).

Wecryl 112 Primer.

Guidance for specification option:

  • A pigmented or non-pigmented primer based on a two-component fast-reactive polymethyl methacrylate resin.
  • For the preparation of asphaltic and bituminous substrates.

Manufacturer guidance

Consult manufacturer and insert requirements.


Manufacturer recommends the following ancillary items:

  • Wecryl 333 Self-Levelling Mortar - For use in levelling rough substrates of less than 10 mm depth, levelling gradients, and as additional protection in trafficked areas such as roof terraces, communal walkways and balconies.
  • Wecryl 842 Mortar - For use in levelling rough substrates of greater than 10 mm depth and levelling of gradients.


Primer

Wecryl 176 resin primer.

Guidance for specification option:

  • A pigmented or non-pigmented primer based on a two-component, fast-reactive and fast-curing polymethyl methacrylate resin.
  • For the preparation of absorbent substrates such as concrete, screeds and timber.

Coatings

Wecryl R 230.

Guidance for specification option:

  • A polymethyl methacrylate-based waterproofing resin.
  • Available in RAL 7032 pebble grey and RAL 7043 traffic grey. Other RAL colours are available on request.

Wecryl R 230 Thix.

Guidance for specification option:

  • Two-component, fast-reactive and highly flexible PMMA-based (polymethyl methacrylate) waterproofing resin.
