DESCRIPTION

KKS® HYPERSTOP DB is a high - performance hydrophilic Butyl Bentonite waterstop, which swells to form a long-lasting watertight compression seal. The swelling action is the result between water and hydrophilic groups which are part of the KKS® HYPERSTOP DB molecular structure.

ADVANTAGES

• Easy to install.
• Long lasting durability.
• Requires no welding or complex detailing.
• Economical - low cost waterstop.
• Conforms easily to irregular surfaces.
• Sustains effective seal in submerged environments.
• Compatible with common building materials, plastics, metals etc.
• Safe for drinking water.
• Non-toxic and zero VOC.
• Swelling properties unaffected by long-term wet/dry cycles.

USES                                                                   

KKS® HYPERSTOP DB is suitable for static construction joints, penetrations, or non-movement sections where there is any concern regarding water penetration.

• Construction joints.
• Concrete foundations and walls.
• Concrete slabs on grade.
• Elevated slabs and ramps.
• Elevator pits and equipment pits.
• Parking structures.
• Swimming pools and water features.
• Water towers, reservoirs and water storage tanks.
• Tunnels, pipes, underground vaults.

DIRECTIONS FOR USE

1. Prep work - carefully brush off all loose dirt dust and debris and apply a suitable contact adhesive. A general solvent-based construction adhesive will suit most situations. In addition, concrete nails can also be used but try to use these in conjunction with an adhesive.
2. Using moderate hand pressure, press a continuous roll of KKS® HYPERSTOP DB into position. Overlap ends approximately 25mm where the strips finish.
3. Peel the protective backing from the exposed side of the Hyperstop DB. Knead the overlapped ends together to form a continuous, uninterrupted seal.
4. Check to be certain the KKS® HYPERSTOP DB has adhered to the area fully.
5. Placement of concrete can proceed as soon as sufficient bond of the KKS® HYPERSTOP DB to the concrete has occurred. Care should be taken not to displace the Hyperstop DB during this process.
6. KKS® HYPERSTOP DB can withstand a slight amount of initial moisture but once fully immersed, swelling commences shortly after and reaches full expansion in approximately 3-7 days, thus placement time of concrete is critical in inclement weather conditions

NOTES/ LIMITATION:

• Do not leave product exposed to inclement weather conditions, which could cause the material to expand prematurely.
• Do not leave product immersed in water prior to concrete placement.
• Ground contaminants or salt water will hinder the amount of swelling achieved. Please refer to our alternative KKS® HYPERSTOP DB products.
