Soil Resistant Split Coupler
Soil Resistant Split Coupler is a Clam Shell type coupler used in Non-Water Tight applications. We use them for perforated or solid style pipes at sites where the native soil is cohesive and stiff enough to minimize the probability of a loose soil infiltration into the pipe to prevent flow restriction.
Veekayplast wrap around style mastic couplers have an outer layer of cross-laminated polyethylene plastic and an underlayer adhesive surface of rubberized mastic material. We can find puncture resistant layer, and high strength shear and of woven polypropylene between these two surface layers. This third layer provides stretch resistance under earth load shifts of settlements and toughness against puncture.
