Hind Hydroswell is a flexible strip, fabricated from hydrophilic expanding rubber in combination with chloroprene rubber. As soon as it comes into contact with water or any other liquids, the ultimate result, it expands to make a water tight seal all around.
Hind Hydroswell when compacted in between prefabricated concrete elements or in-situ concrete swell and expands when it contact with water filling voids in the joints. Due to its flexibility and the capacity of swelling the movement of the construction is absorbed by Hind Hydroswell.
FEATURES AND BENIFITS
The swell-capacity of Hind Hydroswell is infinite and reversible, as a result the durability and the effectiveness for its application gets enhanced throughout the designed life span of the construction.
Hind Hydroswell is designed to resolve all waterproofing problem in the field of civil construction. It is used to make construction and cold joints water tight. It has its application in pipe penetrations , sewage systems , sealing of annular opening for pipe insertion in concrete walls and subterranean prefabricated concrete elements. Hind Hydroswell has already proved its efficient functioning in water reservoirs, swimming pool construction joints, underground car parks, water treatment plants and underground basements.
The surface of the joint should be even, completely dry and free from dust ,oil, grease and laitance. It should be fully ensured that the joint is dry before installing Hind Hydroswell. If moisture or humidity persists, use of a hot air blower is recommended to make the joint surface absolutely dry.
APPLICATION OF ADHESIVE FOR CONTACT
Application of adhesive (glue) is to be done on concrete and Hind Hydroswell. The adhesive should be allowed to become tacky before application to obtain complete adhesion to the surface. Hind Hydroswell is pasted with the smooth and even side towards the existing concrete surface by pressing it onto the tacky adhesive.
Hind Hydroswell is placed in the middle of the joints, between the inner and outer reinforcement bar. The concrete cover around Hind Hydroswell should be minimum of 7cm to counter balance the expansion pressure exerted by the strip. The ends of the Hind Hydroswell are to be butted together. When used in in-situ concrete, the strip can be nailed to prevent from slipping away during concrete pour.
