MGS (Marton Geotechnical Services) was formed as a partnership in 1988 by the two directors, Martin Clegg and Tony Osborne, initially to provide products to the UK on-shore drilling industry mainly wellscreen and Bentonite pellets.

The company grew quickly and began adding to its product range for drillers. The introduction of new landfill gas monitoring legislation through Paper 27 in the UK Landfill Industry led to a demand for HDPE wellscreen and other HDPE products.
