JK-M860 Joint Wrap
External joint wrap M-860 is a pre-formed, cold applied, self-adhering material that is impermeable to water and salt. The adhesive is manufactured from specially formulated elastomeric resins bonded to a woven highly puncture resistant polymer. Blended in the adhesive is an “integrated primer”. The adhesive is protected in roll form by an easily removed polymer release liner.External joint wrap M-860 has been designed to provide a watertight seal on concrete and metal surfaces. It has a tough woven polypropylene backing combined with an extra thick layer of synthetic elastomeric adhesive sealant with integrated primer. It resists severe soil stress on underground applications such as concrete pipe, manholes, septic tanks, vaults and works well on three sided bridges. It can be applied to clean, dry concrete without a primer. (Primer is recommended for temperatures below freezing.)
For use on:
- Concrete Pipe
- Manholes
- Septic Tanks
- Vaults
- Three-sided Bridges
