Providing Bespoke Engineering Solutions Designed Around Your Project Needs

Our solutions are practical, innovative, safe to construct and, where possible, simple to install.

We work in close liaison with our client to provide bespoke solutions to their problems, often working within tight logistical, budget and programme constraints.

In addition to designing systems to lower the water table and piezometric head, OGI has the skills and experience to undertake risk based analysis to assess and mitigate the wider impact of groundwater control, such as potential settlement of adjacent buildings, ground stresses on surrounding infrastructure, and the environmental impact on water resources.
