Newton 303 PolyProof is a hydrophilic, thermo-plastic elastomer water bar, which swells when activated by moisture. It is characterised by high elasticity and high tensile strength. Newton 303 PolyProof can be used to seal the structure against water leaks to both poured concrete and precast construction joints.
Delayed swelling – will not swell during the installation process or during the concrete cure.
Swells up to 4 times its original size to quickly seal leaks at joints in the structure.
Very resistant to the high alkalinity of concrete.
Maintains very high elasticity and tensile strength, even when swollen.
Age resistant, no embrittlement.
Resistant to sewage, chlorine and sulphur.
Suitable for both ‘new to new’ joints and ‘new to old’ joints.
Retains integrity even through many wet/dry cycles.
Primary swelling water bar to seal the joint against leaks through construction joints, movement joints and compression joints to earth retained structures.The following joints can be waterproofed with Newton 303 PolyProof:
Raft – Raft
Raft – Wall
Wall – Wall
Slab – Steel Piled Cut off Wall
Wall – Deck
Slab – Slab
Slab – Wall
Protrusions through the structure
