PolyproofX 1 is a state-of-the-art hydrophilic waterstop, with unmatched durability and water-sealing capacity. It is a swellable, thermo-plastic elastomer, activated by moisture or water, which is characterised by high elasticity, ultimate tensile strength.
The swelling property is achieved through special hydrophilic polymers, which are inseparably enchained with the carrier material (TPE). On contact with water, PolyproofX 1 will swell in a controlled fashion to 400 % of its original size and fills up concrete joint gaps, conforming to the gap variation, creating an effective compression seal. This occurs when the structure is exposed to water from environmental sources eg., rain, humidity, ground water etc.
When properly installed, PolyproofX 1 is capable of sealing heads of water up to 50m and finds wide application in the construction industry to seal horizontal and vertical construction joints of limited movement, for poured in-situ concrete, between new and existing concrete, as well as for precast joint sealing.
PolyproofX 1 comes in various profiles for concrete construction joints, including PolyproofX 1 Smooth, Ribbed, Square, Round, and Hollow.
PolyproofX 1 is treated with a delay coating gel (which is slowly activated by the components of wet concrete) to prevent it from absorbing water from moist green concrete. This stops any premature expansion occurring prior to curing of the concrete. When used against moist green concrete, the initial swelling is therefore time-delayed for approximately 72 hours, to ensure that the surrounding concrete has developed the necessary firmness to withstand such expansion. For use on fully cured, dry-concrete, the PolyproofX 1 Hollow can be use as it is free of the delay coat, ensuring immediate activation when water exposure occurs.
The swelling procedure is reversible. As with any hydrophilic water-stop, PolyproofX 1 will return to its original size if the water or moisture disappears or evaporates. PolyproofX 1 will then re-expand when water or moisture is again introduced into the joint, ensuring it remains water-tight.Some leakage may occur before PolyproofX 1 is fully re-expanded. Repeated wet and dry cycling of this nature does not affect the functioning of PolyproofX 1, and PolyproofX 1 is therefore applicable in areas of alternating water-exposure zones
Due to its high resistance to acids, alkalis, organic solutions etc., PolyproofX 1 offers a wide spectrum of possible applications (sewage treatment plants, bio-gas plants, rain water overflow basins, liquid manure bins etc.). PolyproofX 1 may also be use on uneven or rough surfaces which do not negatively affect the swelling capacity of the tape. It is recommended that Quellpaste X1 or Quellpaste Polymer X1 be used on uneven surfaces to bond the Polyproof X1 tape. These pastes are adhesive but also have hydrophilic properties.
PolyproofX 1 is to be used where watertight integrity is the prime issue. Typical applications where there is a need to achieve a water seal include:-
- Primary and secondary containment structures
- Retaining walls / Foundations - Slabs on grade.
- Sewerage treatment plants
- Water and waste water treatment facilities
- Pipe penetrations
- Subway stations
- Swimming pools / Storage tanks
- Dams, locks, canals, water reservoirs and aqueducts
- Tunnels and culverts
