What is Preprufe made of?
Comprised of a robust HDPE film, pressure-sensitive adhesive and protective coating, PREPRUFE® forms a robust, permanent and aggressive adhesive bond with any concrete slab.
What is Preprufe 300R?
PREPRUFE® 300R Membrane — heavy-duty 1.2mm grade membrane designed for horizontal and vertical use. Designed for use below slabs and on rafts (i.e. mud slabs) and for vertical blindside1 applications. Designed to accept the placing of heavy reinforcement using conventional concrete spacers.
How does preprufe work?
The PREPRUFE® pre-applied waterproofing membrane is a fully bonded adhesive membrane. The bond is continuous below the slab and behind the walls, to form a fully sealed structure. This seal prevents the lateral migration of water into and around the structure.
Is Preprufe a vapor barrier?
Applications. Typical applications include garages, plant rooms, utility grade basements, tunnels; vapor barrier for ground bearing floor slabs with moisture sensitive finishes, e.g. schools, hospitals, wood flooring, etc. For more critical waterproofing applications consider PREPRUFE® 300R.
What is the Preprufe membrane?
GCP PREPRUFE® Plus pre applied waterproofing membranes are unique composite sheets comprised of a thick HDPE ﬁlm, pressure sensitive adhesive, and weather resistant protective coating.
How long does bentonite waterproofing last?
In about 45 minutes, the Bentonite clay sets up resulting in a fairly solid, putty-like material. The Bentonite continues to expand for about the next 30 days as it forms a high-performance watertight membrane against the structure.
Can bentonite get wet?
Bentonite Waterproof Membrane is a high performance self swelling, self healing waterproofing membrane. The bentonite used in its manufacture is capable of repeated cycles of wetting and drying without deterioration of its sealing properties and has a life expectancy measured in thousands of years (BBA Certified).
What happens when bentonite gets wet?
What happens when bentonite gets wet? Sodium bentonite expands when wet, absorbing as much as several times its dry mass in water. The property of swelling also makes sodium bentonite useful as a sealant, since it provides a self-sealing, low permeability barrier. It is used to line the base of landfills, for example.
What is preprufe® 200 membrane?
PREPRUFE® 200 Membrane is a composite sheet membrane comprised of a robust HDPE film, an aggressive pressure-sensitive adhesive and a weather resistant coating. Using patented Advanced Bond Technology, PREPRUFE® 200 Membrane provides a continuous seal that resists water ingress and migration between the membrane and the structure.
What is preprufe 275 membrane?
GCP Applied Technologies’ (“GCP”) PREPRUFE® 275 membrane is a composite sheet comprised of an HDPE film, an aggressive pressure sensitive adhesive and a weather resistant protective coating. Key Benefits. Forms a continuous adhesive bond to concrete poured against it.
