Abstract

This invention relates to liner pipes and to their use in the repair of pipes, preferably in the trenchless reconstruction of underground pipes such as sewer lines.
The liner pipe of the present invention comprises two layers, an outer layer comprised of flexible thermoplastic material and an inner layer comprised of rigid thermoplastic material. When heated, the inner layer becomes sufficiently pliable to allow the cross-sectional shape and size of the liner pipe to conform to the inner cross-sectional shape and size of a host pipe. Because of its structure, the liner pipe of the present invention at least partially overcomes some of the disadvantages of prior art liner pipes relating to ease and expense of installation.
