MacWrap for Box Culverts

External C-877 Type II compliant coupler for full perimeter seal of culverts

Description

External wrap for box culverts, stormwater retention systems, and other four-sided structures.

Box MacWrap products are external sealing bands that create a full perimeter seal on all four sides of a stormwater detention system. A specially-formulated aggressive mastic combined with integrated compression bands makes MacWrap one of the best methods of preventing infiltration of subsurface materials into a box culvert. Box MacWrap is also designed to be leak and puncture-resistant against aggressive backfills.
