Proflex – Hydra Mat is a 3-ply waterproofing membrane designed to waterproof interior sub- floors and walls under thin-set tile applications. It can be installed directly over any cleaned and prepared surface including concrete, plywood, gypsum, cement board, or OSB board. The unique product construction sandwiches a polyethylene membrane between two polypropylene nonwovens to create an impermeable, waterproofing system that stops water from damaging the structure.
Hydra Mat is a pliable, sheet-applied, bonded waterproof membrane and vapor retarder with limited crack-bridging capabilities. It is made of soft polyethylene, which is covered on both sides with a special fleece webbing to anchor the membrane in the thin-set mortar. Hydra Mat was developed as a waterproofing membrane to be used in conjunction with ceramic and stone tile coverings. Tiles can be installed directly on Hydra Mat using the thin-bed method. Other trowel-applied covering materials, such as plaster, can also be used.
Proflex Hydra Mat is a bonded waterproofing membrane and vapor retarder with very low water vapor permeance for use in continuous use steam rooms and similar applications.
Pre-formed sections of Hydra Mat are available for inside and outside corners, pipe protrusions and mixing valve openings.
