Product presentation:

“YUHONG”Brand SAM-921 Wet Installed cross-laminated self-adhesive waterproof membrane is a composite waterproof material formed through cohesive combination between the strong adhesive sealing layer and the strong cross-laminated film at the entrance. The strong adhesive sealing layer should be reactive to cement mortar. The upper surface of this material is strong cross-laminated film and the lower surface is an interleaving paper or isolating membrane which are easy to be removed. This material not only has the excellent performance of cross-laminated film, but also has the perfect cohesive performance with cement mortar.

Advantages

·American Valéron ® (Valéron ®) strong cross Polyethylene film is applied in this product, therefore it has the following excellent performances: Strong puncture resistance, high push-rod tearing resistance, high ripping resistance, high elongation, and excellent dimension stability and low temperature resistant performance.
·We select strong sealant and high quality bitumen and adopt scientific formula for all the ingredients, each base material has perfect cohesive performance, when combined with cement mortar, it forms a mechanical interlocked force through physical absorption and diffusion, in order to have a durable cohesiveness.
·Since the sealant in the product has strong creep property, it is very adaptive to base deformation, and able to meet the construction requirements under many surroundings’condtions. It has a perfect“Self-Healing”performance, which can make up for the only-rigid waterproof performance of concrete , to form flexible and rigid double waterproof effect.
·Cement mortar is fully adhibiting with structure base layer, therefore this product has strong damage resistance and excellent waterproof performance. It prevents liquid water and water vapor from going into structure; and there is no need to apply primer and hot melting, no fire risk, and we don’t require treating the uneven layer, the construction is convenient, safe and environmentally friendly.

Application Range

·widely used to all non-exposed layer, underground and indoor waterproof engineering constructions of various buildings, as well as open-cut subway, tunnel, water pool and canal etc, especially to those which fire is not allowed.
