Aquastop Waterstop is a flexible hydrophilic polymer rubber waterstop designed for sealing construction joints and precast panels. Its unique composition of tightly packed charged microscopic platelets attracts water molecules, causing the material to swell and create an impermeable barrier against water infiltration. This swelling action ensures a permanent pressure seal, even in high hydrostatic pressure conditions.

Uses:
Areas of Application Include:
- Underground structures, tunnels, underground stations, box culverts, pits, retaining walls, manholes, basements, precast panels etc.
- Aquastop is used to stop water infiltration through both vertical and horizontal non-moving construction joints, irregular surfaces and around penetrations through concrete.
- Aquastop should not be used as an expansion joint sealant. It is designed to replace conventional waterstops in construction joints.
- The sodium bentonite in Aquastop is the key to its success.
- Bentonite swells when in contact with water to form an impermeable barrier.
- A permanent pressure seal is formed.
Features & Benefits:
- Lightweight flexible coils easy to install
- Forms a positive seal, sealing cracks & small voids
- Eliminates seem welding & split forming associated with PVC/rubber waterbars
- May be used in potable water tanks
- Non toxic
- Butt end joining. Continuous waterstop
- Can be applied to irregular concrete surfaces
- Withstands hydrostatic head up to 70m
- Unaffected by repeated wetting & drying cycles
- Permanently active system
- Compressible and malleable allowing for good contact in precast applications
- Does not deteriorate
- Self healing
Application Guide
- Prepare surfaces by ensuring they are structurally sound, clean, dry, and free from contaminants.
- Apply Aquastop adhesive to the concrete surface with a brush.
- While the adhesive is still tacky (10-15 minutes), remove the release paper from the Aquastop and press it firmly onto the surface.
- Pay close attention to the highest coil end on vertical sections.
- Butt join the ends of Aquastop tightly to create a continuous seal.
- For specific applications like penetrations, joints to PVC waterstops, pile caps & grade beams, and irregular surfaces, refer to the detailed instructions in the product data sheet.
Limitations
- Not suitable for use as an expansion joint sealant.
- In areas with severe groundwater chemicals or salts, consult with the manufacturer.
- Not self-adhering and requires the use of Aquastop adhesive.
- Standard Aquastop should not be used with contaminated groundwater (saltwater or organic).
