FeHDPlankTM

A method and apparatus for repairing a damaged host pipe, such as a corrugated steel pipe or other conduit. A plurality of interlocking plastic planks are positioned within the invert of the host pipe forming a liner. Rebar is first installed and attached to the host pipe for supporting the planks. A cementitious grout non-shrink grout for concrete such as VELOSIT  NG 511 is installed in the spaces between the liner formed by the interlocking planks and the host pipe so that the 5 mm basaltic coil is encapsulated with the concrete and so that the planks are immovably secured.
