Our equipment

About 306x195 MEG truck new

Our site operations require a relatively small footprint. Generally all plant and equipment is fully self-contained within one or two shipping-type containers or one or two trucks. Alternatively equipment can be removed and relocated inside or alongside a subject structure. For all but the simplest projects, computer control involves fully integrated, robotic survey stations.

In the absence of third party contractors, we can assess sub-soil conditions before and after restoration by using portable hand-operated dynamic penetration devices, without need for vehicle access.

Our materials 

Mainmark (UK) technologies are built on the strength, longevity and certainty of cement and resin grouts.

Our Resources 

Mainmark (UK) has access to our Japanese Partner’s and Mainmark Group’s technical and project experience and know-how. All our work for you will be carried out by Mainmark (UK) using our own equipment, dedicated technicians and Quality Management Systems.
