Use Aquastop Hydrophilic Construction Joint Waterstop for: sealing construction joints, precast panels, and penetrations in underground structures, tunnels, and potable water tanks.
Aquastop is a high-performance hydrophilic waterstop made from flexible polymer rubber, designed to provide a reliable seal in construction joints and precast panels. Upon contact with water, Aquastop expands up to 300%, forming a durable, self-healing barrier. This unique mechanism ensures a permanent seal, even in irregular surfaces and around penetrations. Ideal for use in underground structures, tunnels, and potable water applications, Aquastop withstands hydrostatic pressure up to 70 meters. Its easy installation and non-toxic nature make it a versatile and safe solution for various construction projects.

Frequently Asked Questions About Aquastop Hydrophilic Construction Joint Waterstop
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.
