Sub-Grade and Pavement Drainage


Removing water to increase performance. A track or pavement structure can be weakened by water within, beneath or adjacent to it. Removing this water can improve track bed or road pavement performance. Recognising different requirements. Performance requirements will be different for an unbound pavement in a monsoon region, from an asphalt pavement in an area susceptible to ground frost…. Read more »

Weirs, Culverts and Transverse Structures


Over a century of experience in transverse structures. Transverse Structures are used to control dynamic hydraulic flows carrying solids or sediments. These structures obstruct the flow, changing its hydraulic behaviour and its ability to erode. We have over a century of experience in the selection of appropriate transverse structures, used to control water channel flow…. Read more »

Surface Strengthening & Support


Working to mitigate against unstable surface layers. Certain rock slopes have an unstable surface layer which often requires additional stabilisation. We offer a range of high strength mesh systems which are designed to work in conjunction with anchorages, to increase the stability of the unstable surficial layer. Key factors to consider in limiting unstable mass… Read more »
