Soil Engineering and BachySoletanche develop a win, win, win solution for grouting sites

Soil Engineering Geoservices have implemented the use of a dust free mixing system on one of their bulk infill grouting sites.

As part of the on-going works currently being undertaken for Network Rails Borders Rail scheme, SEG were asked to carry out grouting works adjacent to a hospital.

In order to minimise noise, vibration and air pollution and improve the working environment for the site staff, SEG worked with the intergroup expertise of Bachy Soletanche to develop the dust free mixing system. The outcome is a system capable of mixing up to 200t of PFA grout per shift, with minimal dust produced. The computer controlled mixer produces a consistent grout, of reliable characteristics, mix after mix after mix after mix. The system controls its own material silos and water supply, using a MAT SC20K mixer station and requires only a single operator to manage the plant, whilst the 6m3 storage pan allows a significant buffer quantity to minimise delays in grout injection.

In testing, commissioning, and now in full production, the dust output of the system is virtually nil, and the electric power plant ensures low noise levels and reduced vibration, thus providing a much improved operator environment. The self-weighing system incorporated with in the plant ensures accurate material control, and minimises wastage whilst providing a high quality product consistently.

Not only is the system sympathetic to ever increasing environmental demands it also improves production and reduces waste ensuring a win, win, win situation for grouting sites.
