MiraSTOP™ BW

MiraSTOP BW is a Bentonite Waterstop that swells when in contact with water. This high quality, self-adhering, flexible, coiled waterstop strip is comprised of butyl rubber polymers and expandable bentonite clay waterproofing joint compound.

MiraSTOP BW is designed for use in non-moving joints to create watertight concrete joints. MiraSTOP BW is ideal for many types of cast-in-place and precast below-grade concrete applications, such as: construction joints in foundation slabs and below-grade walls, precast concrete wall panel systems, septic tanks, sanitary and storm sewer manholes, pipes, utility and burial vaults, wet walls, box culverts and portable water tanks.

MiraSTOP BW prevents infiltration of below-grade moisture in non-moving joints. When water comes in contact with MiraSTOP BW it swells to form a strong compression seal. MiraSTOP BW is ideal for a variety of applications:

• Vertical and horizontal concrete 8" (200 mm) thick or greater
• Shotcrete foundation walls
• High hydrostatic pressures
• Tie-back plates and penetrations
