ABSTRACT:
The present invention provides methods of grouting a subsurface conduit whereby the hardened grout resists stress failures. The methods basically comprise the steps of forming a hardenable grout composition having elastomeric properties upon hardening, placing the hardenable grout composition adjacent to the outside of a subsurface conduit whereby upon hardening the grout composition forms an elastomeric solid support for the conduit and allowing the hardenable grout composition to harden into an elastomeric solid mass.
