Abstract: 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.

Abstract: The present invention provides a compressible seal for installation in joints in concrete pavement, the machine for installing the seal and the method of installation. The seal is a preformed, closed cell, elastomeric cylinder or rope. The seal defines a round cross section in its relaxed, i.e., uncompressed, state somewhat larger than the joint into which it will be installed. The installation machine is a wheeled, hand powered device having a first guide wheel which is received within the joint, an aligned installation wheel which installs the seal in the joint, a second guide wheel which ensures that the seal is at the proper depth in the joint and a pair of contra-circulating belts which feed the seal to the installation wheel.
