Hydrophilic Swell Bar
Hydrophilic Swell Bar is used for sealing of concrete construction joints, pre-cast concrete segments, proofing of shafts and pipe penetration subject to continuous or intermittent hydrostatic pressure. It swells in contact with water to seal the gaps and pores in a concrete joint. It can swell up to 450%.
ADVANTAGES AND FUNCTIONS- Easy and secure application
- Good Swelling properties on contact with water
- Good Elastic Properties
- Permanent water resistance, no leaching
- Non-Polluting, ecological user friendly system
- Need no harding time

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.
