Measure the resistance of concrete with PWS 1000 to Chloride Ion Penetration

United States Testing Company, Inc. Tulsa Division

Untreated concrete had 15 times the Chloride Ion content than concrete treated with PWS 1000

ASTM 793-75

Measure the effects of accelerated weathering on Silicone Rubber

General Electric Company

After a total of 4000 hours, the silicone rubber showed no signs of deterioration. It was estimated that 4000 hours of accelerated weathering is equivalent to 30 years of actual weathering in the field.

GEOSCIENCE LTD

PWS 1000 withstood up to 2.8 atmospheres of hydrostatic pressure before compromise

ASTM E-303

Measure surface frictional properties of concrete treated with PWS 1000

United States Testing Company, Inc. Tulsa Division

No significant change was noted in frictional properties of concrete after treatment with PWS 1000

ASTM E-514

Measure the water penetration and leakage through masonry surfaces treated with PWS 1000

N/A

Measure the cured compressive strength of freshly poured concrete treated with PWS 1000

United States Testing Company, Inc. Tulsa Division

Freshly poured concrete treated with PWS 1000 experienced a 13.7% increase in Compressive strength over untreated concrete after a 28 day cycle

N/A

Measure the changes in gas permeability and water transmission of concrete treated with PWS 1000

United States Testing Company, Inc. Tulsa Division

Concrete treated with PWS 1000 was able to "breath" or pass water vapor through the sealant. Water absorption of untreated concrete was 91.7% greater than that of concrete treated with PWS 1000
