Swellable Water BarSwellable Water Bar Description : Swellable Water Bar - Conventional Pre-formed water bars have not been user friendly and often failed because it hindered the concreting because of its bulky size in the shutter and the nailing of the water bars to the shutters to keep them in position, punctured the water-bars and made them ineffective. Swellable Water Bar,keeping this in view Siddhi Rubber Udyog introduces user friendly and most effective Hydro Swellable water bar for constructions joints which swell in the centre of the construction joint post construction under pressure when it comes in contract with the water from leakages, effectively blocking the leakages. Hydroswell is a neoprene based hydrofillic construction joint water bar which expands to 250% of its original volume in the construction joint when it comes in the contract with water post construction. Swellable Water Bar is user friendly,It only needs nailing in position at the center of the construction joint just before the subsequent pour.
Swellable Water Bar Installation: Make sure that the concrete is dry, clean the surface and make it smooth, free from any loose material . Just before the subsequent lift of the concrete is poured nail Siddhi Rubber at the centre of the construction joint at an interval of 30 centimeter C/C . When one piece of the Hydroswell has to be joined with the subsequent one at the end of the length do not over-lap Hydroswell but lay it close to the end in a butt joint. Hydroswell is supplied with a water retardant coating to guard against premature expansion or the swell of the product during construction. It is still recommended that the product is not used during rainy spells . Swellable Water Bar Specifications: Available Size: 25 x 20 mm; Free expansion in distilled water at least six times the initial volume without loss of cohesion of mass Density : 1.4 gms/CC Hardness: 50 HAD Swelling 300% Mass greater than 1.10 Kg / m. Pressure of swelling greater than 600 KPA after 48hours. Pressure of swelling less than 100 KPA after 6 hours. Stability in salt solutions, and aggressive resistance to inhibition of calcium and magnesium ions, Resistance to hydrostatic pressure, under both continuous immersion and wet / dry cycling.
