| Mastic Banding: | | | |
| Description: The band is self adhering rubberized mastic reinforced with geotextile fabric and a polyethylene outer cover. Securing bands wrap around the pipe to form a positive seal. |
| Installation Instructions: Cut out the damaged area, make cuts in the center of the corrugation valley. Cut the replacement pipe section to the desired length. Trim any polyethylene burrs from saw cut. Excavate bedding from under the existing pipe cut ends. A protective peel away paper is removed from the back of the band to expose a tacky mastic surface. Ensure that the pipe is clean and free from debris. The band is then adhered to the entire circumference of the pipe. Straps on the band tighten to provide a positive seal. Carefully replace and compact bedding and backfill to provide proper support for pipe and coupler. |
| For cracks, joint defects and minor damage excavate from under the existing pipe to a width greater than the bands. Center the coupler over the damaged area. A protective peel away paper is removed from the back of the band to expose a tacky mastic surface. Ensure that the pipe is clean and free from debris. The band is then adhered to the entire circumference of the pipe. Straps on the band tighten to provide a positive seal. Carefully replace and compact bedding and backfill to provide proper support for pipe and coupler. |
