Garlock RISER-WRAP Installation Manual
RISER-WRAP®
Water Infiltration Sealing System
RISER-WRAP®
The Riser-Wrap® seal is a two-layer system designed
for corrosion and sealing protection on pipelines and
encapsulating manholes to seal joints against ground water
infiltration.
The first layer is a visco-elastic adhesive liquid sealant
covered by a heat shrink sleeve. The heat shrink is a thickwalled .098” (2.5mm),cross-linked, high density polyethylene
membrane.

TYPICAL SPECIFICATIONS
1.0 Scope
Apply RISERWRAP® heat shrinkable sleeve on exterior
concrete manholes or other structures at locations
indicated by the Engineer to protect manhole and reduce
infiltration or ingress of water and other contaminates.
The sleeve needs be applied over a cleaned, primed
surface.
2.0 Sleeve - High Density Polyethylene Membrane
The heat shrinkable sleeve consists of an 11” or 17”
wide wrap-around, 2.5mm thick, cross-linked high density
polyethylene membrane complete with a mastic. Peel
Strength is a minimum of 11 lb./in. per ASTM D 1000.
Tensile Strength is 3,300 psi minimum per ASTM D-638.
Mastic softening point should meet or exceed 400°F
in accordance with ASTM E-28. Sleeve will incorporate
permanent heat indicators, to assure proper heating.
3.0 Joiner-Strip
The material to close the sleeve consists of a high
density polyethylene fiber reinforced material to assure
sleeve pulls tight. Lap Shear on assembled system will
exceed 18psi per ASTM D-1002.
4.0 Primer
Primer is a Polyken 1027 or 1039. Primer needs be black
in color and applied at a rate of approximately 2 – 3 mills.
Must be able to dry with-in one hour.
