Technical Literature

MiraSTOP NBW is a Non-Bentonite Waterstop that swells when it comes in contact with water. This high-quality, flexible, coiled waterstop strip is comprised of chloroprene rubber.

MiraSTOP NBW is designed for use in non-moving joints to create watertight concrete joints. MiraSTOP NBW 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 NBW prevents infi ltration of below-grade moisture in nonmoving joints. When water comes in contact with MiraSTOP NBW, it swells to form a strong compression seal. MiraSTOP NBW is ideal for a variety of applications:
