BENTONITA G.B.

CHARACTERISTICS:
BENTONITA G.B. is a joint made of bentonite and butyl rubber used for waterproofing in construction joints.
It may be used in saline environments and contaminated water.

BEHAVIOUR:
While the concrete is setting, small cracks may appear in joints where water could penetrate afterwards. When the product gets in contact with water it expands up to 400% its initial volume thus providing excellent waterproofing. This way, capillary cracks and holes are waterproofed in an optimal way.
