The Wecryl Surface Protection System OS 10 – 2.0 is a high-quality and highly flexible PMMA waterproofing system that is approved by the DAfStb guideline on the "Protection and repair of concrete components". This makes the waterproofing system suitable for areas subjected to foot and vehicle traffic when applied under protective and covering layers.

The surface design can feature a wide range of colours as well as patterns or markings. The fact that this system, with its high bonding strength on almost any substrate, is applied as a liquid kit makes it a cost-efficient and high-quality solution, especially for the refurbishment of multi-storey car parks.

System components:

Wecryl 171 - Low-viscosity primer for mineral substrates.
Wecryl R 230 thix - Waterproofing resin.
Wecryl 279 - Waterproofing resin under protective and covering layers.
Wecryl 333 - Self-levelling mortar.
Quartz sand 0.71–1.25 mm/ Emery aggregate 1–3 mm.
Wecryl 488 - Pigmented sealer (finish).

Features and benefits:

Highly flexible and crack-bridging even at temperatures as low as and including -30°C.
Class OS 10 approval according to the guideline for the protection and repair of concrete components issued by the German Committee on Reinforced Concrete (DAfStb), October 2001.
Waterproofing layer (PESPL) can be installed as waterproofing of a continuous area without an embedded fleece.
Reaction to fire classification Cfl-s1.
Able to withstand high mechanical stress (e.g. through heavy vehicle and pedestrian traffic).
Fully bonded to the substrate, therefore no flow paths underneath for water.
