XYLASTIC® Swellable Waterstop 1.0

XYLASTIC® SWELLABLE WATERSTOP – 1.0 is a hydrophilic natural sodium bentonite and synthetic rubber compound which expands in a controlled fashion when exposed to moisture, forming a gasket and compression seal in concrete construction joints.

XYLASTIC® SWELLABLE WATERSTOP – 1.0 is ideal to be used in horizontal and vertical construction joints for cast in-situ concrete structures.

XYLASTIC® SWELLABLE WATERSTOP – 1.0 is manufactured from utilizing a specialized mixing process which encapsulates hydrophilic materials into a rubber base, creating a controlled, moisture-activated seal.

The product has the structural integrity of a rubber-based sealant, the long term durability features of a bentonite- sealant, as well as the ability to expand to create a SELF-HEALING WATERSTOP JOINT MATERIAL.

XYLASTIC® SWELLABLE WATERSTOP – 1.0 is a permanently active system, which swell up to approximately 300%. The first expansion is delayed to prevent the strip from reacting too soon with possible rainwater, before or after installation.

The swelling properties are created by the particle structure of the clay in contact with water and in confined condition.

PRODUCT ADVANTAGES

• Excellent for application onto rough or smooth concrete surfaces.
• For use in horizontal and vertical construction joints.
• Allows concrete to gain strength before expansion takes place (expansion delay system).
• Ability to expand over 300% or original size.
• Excellent adhesion to the concrete surface with the use of SOLVENT-BASED ADHESIVE.
• Can be bedded into the wet concrete of the 1st pour prior to the concrete set taking place.
• No compaction or displacement problems during casting due to the size and shape of the waterstop.
• Unaffected by repeated wet and dry cycles.
• Has the ability to bond to the 2nd pour of concrete to form a gasket seal inside the joint.
• Can withstand a hydrostatic water head pressure of 6 bar (60 metres) in potable and salt water conditions.
• No on-site welding required as with conventional PVC waterstops.
• Very easy to handle and to install.
• No split form-working required.
• Non toxic and requires no special handling and can be used in potable water applications.
• Very wide application and serviceability temperature ranges.
• Can be exposed to wet environments prior to the 2nd pour taking place due to the products expansion delay
  system which allows minimal expansion within the first 3 days of full submersion in water.
