PRE-APPLIED WATERPROOFING MEMBRANE WITH INNOVATIVE TECHNOLOGY
that bonds integrally to poured concrete for use below slabs or behind basement walls on confined sites
Why High Density Polyethylene (HDPE) sheet?
High-Density Polyethylene (HDPE) sheet is a major component of the PRE-TEC MEMBRANE. The functions of the HDPE are to
1) provide a portion of the waterproofing protection for the structure
2) provide increased resistance of the waterproofing adhesive from environmental exposure and backfill.
HDPE membrane was chosen for this purpose because it has excellent mechanical properties required for this application including high puncture, tear, and tensile strengths as well as good elongation for bridging any post formed cracks in the structure. The other advantage of HDPE is that it is extremely resistant to attack and degradation from most chemicals. Consequently, it is typically a leading candidate for use in geomembranes including landfills containment systems, pond liners, and holding tanks for waste liquids.
Why Fully Bonded to Concrete?
• In case of damages in waterproofing layer, no pene tra on of water between membrane and concrete.
• Reduc on of water leakages >98%
• Cracks s ll occur, but no water penetra on
• Less crack injec on is required • No bonding to blinding concrete
ADVANTAGES OF SEALING MEMBRANES TECHNOLOGY
Fully bonded to poured concrete, which forms an integral bond to poured concrete by pressure-sensitive adhesive and remains in place if settlement of the substrate occurs.
The unique continuous adhesive bond to concrete poured against it prevents water migration and makes it unaffected by ground settlement beneath slabs.
Prevent water from leaking into gaps between waterproof membranes and structure.
Excellent adhesion to vertical and horizontal surfaces.
Designed with advanced bond technology.
CRYSTARM technology helps to protect the environment during the manufacture, and use of the product.
No lateral water underflow.
Excellent resistance to water, chlorides, sulfates, dilute alkalis, acids, and any other and chemical attack.
Excellent tear and puncture resistance.
UV-resistant for more than 60 days depend on the weather situation.
Highly crack bridging.
Effective against extreme hydrostatic pressure.
Gas resistance and restriction of the ingress of Methane, Radon, Benzene, Toluene, Gasoline & other VOCs.
Permanently waterproof and active for long lifespan.
No need to use fire at project site.
No welding, no open flame, and no special equipment.
Self-protecting no need for a protection layer.
Trafficable membrane immediately after application and ready for immediate placing of reinforcement Membrane is unaffected by wet jobsite conditions.
Reduces construction scheduling time.
Simple overlapping jointing.
Can be applied on dry or wet substrate.
THE HIGHEST PROTECTION FOR HIGH SAFETY
Used for all types of waterproofing in:
PRE – TEC MEMBRANE WATERPROOFING DESIGN
In the case of the concrete layer being damaged, PRE-TEC membrane effect can still be achieved to waterproof concrete due to its comprehensive functions
ORDINARY WATERPROOFING DESIGN
When foundation settlement occurs, the waterproofing layer is damaged, disabling the waterproof functions.
PRE-TEC MEMBRANE WATERPROOFING DESIGN
When foundation settlement occurs, the PRE-TEC waterproofing layer can still exert functions (FULLY BONDED)

PERMANENTLY WATERPROOF TECHNOLOGY AND ACTIVE FOR LONG LIFESPAN
The basement structure tends to get damaged because of the situation it is situated. i.e., below the ground level. The level of water, the pressure of rising water, moisture ingress into the structure, chemicals in the soil, the root of the plant/trees, heat in the soil, movement, etc., are the main causes of failing the sub-structure; but, can be sorted out by the process of waterproofing treatment. Waterproofing treatment means, making the structure waterproof or water-resistant using Waterproof chemicals like liquid-applied or sheet-applied membranes.
The liquid waterproofing membrane system in basements is difficult if a substrate is damp from water as it inhibits the bond. On the other hand, Sheet-applied membranes that are self-adhesive or installed using adhesive also face the same problem. If the retaining wall is confined (blindsided with no space between the soil and the structure), no chance of doing positive side waterproofing using these products.
The best product is the one, that can be loosely laid before the raft / horizontal surfaces, and after the installation, the membrane should get bonded to the basement structure. This will completely cease water movement between the membrane and the structure, creating a building envelope.
