HYDROPHILIC BENTONITE STRIP FOR WATERPROOFING OF CONSTRUCTION JOINTS IN CONCRETE
SPETEC® BST300 is a black hydrophilic strip 25 x 20 mm made of sodium bentonite and rubber with special fillers and crystalline admixture. SPETEC® BST300 is placed where the joint will arise. The sealing of the joint is realized by crystallization of additives in, and the swelling of the strip. In contact with water and in confined conditions, SPETEC® BST300 will swell and stop the water infiltration.
FIELDS OF APPLICATION
SPETEC® BST300 is used in:
• Construction joints in concrete
• Cold joints
• Pipe penetrations through concrete
• Joints between pre-casted concrete elements like water tanks and manholes.
• Joints between floor slabs/walls and secant pile walls/slurry walls/ sheet piles…
CONSUMPTION
The consumption depends on the total length of the construction joint that needs to be sealed. Keep in mind that you need a lateral overlapping from 5 to 10 cm.
