  • Quick Dams Frequently Asked Questions

    QUICK DAMS FREQUENTLY ASKED QUESTIONS Q: Quick Dams, what are they & how do they work? A: Quick Dams contain a super absorbent polymer (similar to what’s found in baby diapers and meat pads) that react and swell on contact with water. Once activated (typically 5 minutes if there is enough water), the water is contained as a gel within the black fabric, thus acting as a barrier and …
