Seal Right Swellable Bar
Seal Right Swellable Bar :
Seal Right is a polymer based Hydrophilic water bar which is BTRA, ISO 4633, BIS approved.
These are used in construction joints which slowly swells when in contact with water and waterproof’s the construction joints.
The pressure of swelling causes the water bar to place itself exactly into the joint and effectively stop seepage even at high pressure.
Seal right water bar’s have a lifetime swelling capacity of upto 800%
Application of Swellable Water Bar
Used for concrete joints, and intersections of old and new concrete in the construction of pools, foundations, tunnels, manholes, retaining walls, garages, curtain walls, water deposits, water purification facilities and pipe penetrations into above-mentioned constructions.

Volume recovery after Swelling: As the Swell Bar is made with Hydrophilic polymer not with hydrophilic filler, it takes water with contact of water and after removing from water it releases water with time and come to original position within a certain time and it can be used again as swell bar. These cycles will go long as the polymeric material does not deteriorate its properties.
Shelf Life: As the swell bar is a composition of synthetic polymeric material, it has weather resistance properties, and shelf life ranges from 5-7 years in shaded area with controlled temperature from 23-30°C and with no stress on packed material.
