IMPERSTOP “RR” with retardant coating
Bentonite re-inflating tape for low-cost waterproofing connecting concrete castings. The Imperstop “RR” inflating bentonite tape stands out for its new special patented coating that retards premature inflation due to rain by 2-3 days.
The special coating acts according to the pH value. Rain with a pH value of 7 (neutral) will not dissolve the coating for 2-3 days. The special coating is chemically dissolved during installation with fresh cement, which instead has a pH value=11 (alkaline, it may vary slightly according to the quality of the concrete).
