Non-return valve for a resin injection system and resin injection system incorporating same

The present invention provides a non-return valve for a resin injection system, especially for use in electrical cable joints, comprising: a valve housing which includes an outlet for a fluid flowing through the valve; and a valve body which is held by the valve housing and is freely movable between a closed position, in which the outlet is substantially sealed or closed to fluid flow by the valve body, and an open position, in which the outlet is substantially open to fluid flow. Thus, with the present invention, the valve body can be loosely held by the valve housing and the valve need not include any spring means to bias the valve body to the closed position. The invention also provides a resin injection system for sealing a localized breach in an object, such as an electrical cable joint.

SEAL MEMBER, SYSTEM AND METHOD OF SEALING A MICRO TRENCH

A variety of spoolable gaskets are configured to seat within a micro trench to form a water tight, damage-resistant seal. In some aspects, the seal may be removed to allow for subsequent access to utilities installed therein. The seal has a suitable compressive strength to support the trench walls without damaging the pavement and accommodates expansion and contraction of the micro trench and pavement caused by changes in temperature. Systems and methods involving the seal member are also disclosed.
