Sections measure 48-inches high, but are stackable to accommodate any riser pipe height and cutting. Then a ratchet strap is used to temporarily hold the halves together, with supplied nylon straps used to hold them in place permanently.

Users install Riser Wrap by hand from the bottom up, making sure the top of the two halves align within the same riser rib. “In addition, the smooth outer wall of this product inhibits surrounding soils and frost from embedding into the pipe’s grooves, which can lead to heaving of riser pipes.” “The structural integrity of the interlocking foam sections also greatly strengthens grade-ring and riser connections,” he says. Read says the design and rigidity of the foam does more than insulate. The foam is formed with interior ribs to fit snugly between the ribs of existing PVC. Riser Wraps are molded with a tongue-and-groove system that joins halves with a tight, closed seam, securing the wrap around 24-inch ribbed PVC pipe.
The final product has an R-10 insulation rating. “When we designed the AWS Riser Wrap, we knew it had to be easy to install, and have a high insulating R-value,” says Kory Read, commercial sales rep for AWS. As a solution, AWS developed the Riser Wrap, a product made from expanded polystyrene, a rigid closed-cell foam, to insulate risers against frost. The team at Alberta Wilbert Sales noticed that septic risers can be prone to frost-heaving, compromising connections and seals and leading to water infiltration into tanks during the spring thaw.
Damage to pumps and fittings inside of tanks are an all too common result when proper precautions aren’t taken during the design and installation of systems. Freezing temperatures can be hard on septic systems.
