Pasco Aquastop is a hydrophilic polymer rubber waterstop engineered to seal non-moving construction joints and precast panels in high-pressure underground environments. This sodium bentonite technology utilizes charged microscopic platelets that compact under pressure to withstand a 70m hydrostatic head while providing a self-healing seal that fills cracks and voids.
Potable water certified and resistant to repeated wet-dry cycling, it ensures continuous watertight integrity around complex penetrations and irregular concrete surfaces where traditional rigid waterbars often fail.
Q: How does Aquastop work to prevent water infiltration?
A: Aquastop contains sodium bentonite, which expands upon contact with water, creating an impermeable barrier. The expansion fills cracks and voids, forming a self-healing seal that prevents water migration.
Q: Can Aquastop be used in potable water applications?
A: Yes, Aquastop is non-toxic and safe for use in potable water tanks and other drinking water applications.
Q: What is the maximum hydrostatic pressure Aquastop can withstand?
A: Aquastop can withstand hydrostatic pressure up to 70 meters, making it suitable for high-pressure environments like underground structures and tunnels.
Q: How do I install Aquastop around pipe penetrations?
A: Install Aquastop around the outer diameter of the pipe or sleeve. For sleeved pipes with large gaps, install additional strips. Fill any remaining void with non-shrink cementitious grout.
Q: What surface preparation is required before applying Aquastop?
A: Surfaces must be structurally sound and free of dirt, dust, grease, paint, oil, form release, curing agents, and other contaminants. Remove standing water before application.
