What is a PMT?

The prebored PMT test involves expanding radially a cylindrical probe inserted in a carefully predrilled hole. The pressures and volume expansions required to approximately double the probe volume are measured.

InSitu Tech Inc. conducts tests to ASTM 4719-87 and, based on their vast experience in soil interpretation, will add unload-reload cycles and/or creep sections when necessary to match the client's foundation needs.
