Site Investigation Contracting

SWG site investigation contracting service is second to none in the region. With the advantage of our own drilling plant and in-house testing facilities (both in-situ and laboratory), we are able to provide an unequalled service in terms of quality, expediency and versatilty that contractors from out of the region struggle to compete with.
