Manhole Joint Wrap Seals


Infiltration and Extravasation Prevention


Manhole and pipe joint rubberized mastic wrap seals: press into the joint and pours of concrete to make a waterproof seal..

The rubberized mastic bonds permanently with the structure wall and prevents infiltration into the precast system.

Joint wrap seals for RCP Pipe and Manholes is an advanced external joint wrap seal specifically designed for preventing infiltration.

Joint wraps may be used on reinforced Concrete pipes, Manhole sections, and other round or elliptical concrete structures.

The joint wrap exceeds ASTM C 877 (Type II), standards for external joint seals, Specified use for RCP and structures in a customized external sealing band. 

A mastic base layer adheres aggressively to concrete, and continues to “cold flow” at typical ground temperatures. Back filling actually increasing its bonding capability.

An internally laminated layer of high shear strength woven polypropylene increases puncture and shear resistance. Flexibility of the joint wrap will accommodate some settlement at the joint gap.

Manhole seal infiltration barrier are protected from corrosion, acids, alkalines and other commonly entrained pollutants by a heavy duty backing.

Seal reinforced concrete structures.


Reinforced concrete structures joint wrap, is an external joint seal used on a variety of precast reinforced concrete structures.

The wrap prevents infiltration and exfiltration at both vertical and horizontal connections and joint gaps


Seal joints on storm-water retention systems, box culverts, junction boxes, septic and many other precast structures.

Pipe Joint wraps prevent infiltration at connections of Reinforced Concrete pipe.



Custom backings are available to resist and prevent infiltration of high concentrations of hydrocarbons.

Joint wraps are also available for permanent above ground installations.

Pipe sealing wraps may be used on most pipe types. Leaking Bells and damage leaks of pipes with low pressure media may be externally sealed using compression strap pipe wraps.

Groundwater enters the sewer collection system through leaky manholes joints. Inflow into the manhole can be prevented by installing a joint wrap seals.

External Joint Wrap is a custom compounded butyl-based sealant specifically designed to create a high performance seal in precast structures and pipe joints.


By applying and external tape seal, manhole joints are protected against water infiltration. The sealing tape provides a complete watertight seal.

External Joint Wraps provide excellent adhesive and cohesive strength, they are self-priming and self-healing. Highly resistive to temperature extremes and acid or caustic environments. External joint wrap remains permanently flexible is easy to applied, are high-performance seals.

In addition to leaks occurring at the section joints, the pipe-to-manhole connection points also may be a leaking problem. See Pipe-to-Manhole Connector Seals: ; and LPS link sealing of pipe connections


Manhole Test Plugs


Manhole most common size is DN 600 - 1000

For manhole leak testing a air inflatable plug is used.

The plug is relatively short and light, equipped with eyelet bolts for simple vertical positioning of a plug.

Standard accessories available for testing tightness with air.
