ABSTRACT:
A method of bedding a load-carrying member on a supporting foundation in which one or more open-ended axially compressible moulds are placed on the foundation and a bonding agent which includes a thermosetting resin capable of bonding to both the underside of the member and to the foundation is placed in the mould or moulds. The member is then placed on the mould or moulds and, by its own weight, or by a superimposed load, compresses the mould or moulds axially until the member is itself pressed into contact with the bonding agent, which is contained laterally by the mould or moulds, the bonding agent then being allowed or caused to harden. The method is particularly useful for bedding manhole covers on a manhole wall.
An apparatus for carrying out the method comprises a number of open-ended axially compressible moulds, a container containing a liquid synthetic resin and an accelerator and a second container containing a mixture comprising a granular filler, which is inert to synthetic resin, and a hardening catalyst for the resin.
