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.
Green Roofs.
Blue Roofs.

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 cold applied inverted structural waterproofing for podiums, roofs, balconies and terraces and certified for green roofs, blue roofs and stormwater attenuation.

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.
Flame free.
Cold applied.

Specification data - Cold-applied liquid waterproofing systems

Substrates	-
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.
Pointing and filling mortar	- 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.
Tanking	-
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. Wecryl R 230 thix is a variant of Wecryl 230 with improved non-sag/ thixotropic properties to reduce run-off when the waterproofing resin is applied to sloping and vertical surfaces. It is used primarily for the waterproofing of details. Available in RAL 7032 pebble grey and RAL 7043 traffic grey. Other RAL colours are available on request. Wecryl R 230. Guidance for specification option: A low-temperature installation version of the standard resin, with a modified cure system. For use to allow application between -15 to +25°C. Available in RAL 7032 pebble grey. Other RAL colours are available on request.
Reinforcement	Weplus Fleece. Guidance for specification option: A 110 g·m² polyester fleece.
Protection	-
Horizontal protection	- Manufacturer guidance Consult manufacturer and insert requirements or omit.
Vertical protection	- Manufacturer guidance Consult manufacturer and insert requirements or omit.
Jointing tape	- Manufacturer guidance If existing expansion joints must be waterproofed, a joint tape and two layers of waterproofing with fleecing reinforcement must be applied along the centre of the joint. Consult manufacturer and insert requirements or omit.
Pipe sleeves	- Manufacturer guidance Consult manufacturer and insert requirements or omit.

Integral accessories	Wekat Catalyst. Guidance for specification option: A polymethyl methacrylate-based catalyst, used with all three resin versions as a two-component system. Must be mixed with the resin for two minutes in accordance with the certificate holder's instructions using a mixing tool with twin-paddle stirrer at slow-speed setting. Supplied in a plastic bag or cardboard container.
Colour/ Finish	RAL 7032 pebble grey. RAL 7043 traffic grey. Other. Guidance for specification option: Other RAL colours available on request. Manufacturer guidance Wecryl R 230 /-thix /-TT.
