KingSwell STD®
High performance hydrophilic waterstops.
Overview
KingSwell STD is made of bentonite free high performance polymer modified chloroprene rubber strips. The swelling action is the result between water and hydrophilic groups which are part of the KingSwell STD molecular structure. Expansion of the waterstop creates a positive seal against the face of the concrete joint and prevents the water entry into the structure through the protected joint.
Applications
- Hydrophilic waterstop can be applied against existing concrete and are simply installed by nailing or using a hydrophilic adhesive. In contact with water, KingSwell STD strips react and swell to form a compression seal
- Hydrophilic strips are suitable for installation in contraction and construction joints. KingSwell STD is used primarily for foundation walls slabs, slabs-on-grade, pre-cast wall panels, manholes, pipe connections, box culverts, utility and wet wells, and potable water tanks
Advantages
- Active protection- KingSwell STD hydrophilic waterstop swell in contact with water to form an effective compression joints
- Simple application and jointing techniques
- Slow expansion rate to prevent damage to freshly placed concrete during curing
- Retains original shape after repeated and contraction
- Swelling properties unaffected by long term wet/dry cycling
- Sustains effective seal in wet conditions
- METHOD OF INSTALLATION KingSwell STD can be installed either by suitable adhesive using KingSwell STDS or mechanically by nails
- When using KingSwell STDS adhesive, extrude enough materials on a sound clean substrates and immediately fix firmly KingSwell STD into KingSwell STDS adhesive

| resistance | Also KingSwell STD can be fastened in place using masonry nails at approximately 300 mm centers. Care should be taken however to ensure that the substrate has sufficient strength to enable a mechanical fixing to be securely driven without damaging the KingSwell STD. Alternatively, a groove can be cast into concrete to facilitate application. KingSwell STD is suitable for use in most weather conditions, but heavy rain or prolonged immersion will cause premature swelling. Should this occur, it will be necessary to allow it to dry out, or be dried with a hot air gun before concrete pouring takes place. KingSwell STD should not be used in expansion joints, or any concrete section of less than 150 mm width. | — |
