CWPA 800 Concrete Waterproofing Admixture

Each manufactured lot of CWPA 800 is produced under some of the most exacting chemical manufacturing processes available. CWPA 800 has been proven to significantly enhance the physical properties of ready-mixed concrete through extensive independent testing.

• Reduced Permeability (per ASTM D5084):
o 98% less permeable as compared to non-treated specimen
o Protects against alkali and efflorescence attack from the concrete
o Inhibits corrosion due to decreased permeability of concrete

• Mitigating Effect on ASR (per ASTM C1260):
o 10% reduction of effects of ASR compared undosed control

• Mitigating Effect on Shrinkage (per ASTM C157):
o 10% shrinkage reduction by day 28 from casting of specimen
o Reduces slab warp, plastic shrinkage cracking and crazing

• Rapid Strength Gain (per ASTM C39/39M):
o Achieves design strength in as little as three days after casing of specimen due to internal curing
o No thermal cracking

• Type S Admixture (per ASTM C494/C494M)
o Full compliance with published requirements

• Completely blocked water migration through hardened concrete
o Per CRD C48-92
