The geology to the west of Mold in North Wales has a long history of extractive industries. Mineralised veins within the rocks have been mined for lead, and mine voids have been used for drainage and storage, including munitions and explosives. At Cambrian Quarry in Gwernymynydd, underground workings extracted the… ∞
Engineering work on the weir of Ennerdale Water in the 1950s raised the level of the lake, increasing its storage capacity and ensuring a more secure potable water supply. As part of this work, one of the tributaries of the River Ehen (Ben Gill) was diverted to Ennerdale Water via… ∞
Working in partnership with Stormwater Management Ltd we have provided the technical support to assist in the design and construct an innovative sustainable urban drainage system – the Elevator attenuation storage tank.

Evidence of both deep seated and shallow instability had been reported on the Down slope of the Eltham embankment located approximately 300m to the west of Eltham Station between Eltham and Kidbrooke stations at ELR: BEX 8m 61.5ch to 8m 70ch. Remedial works in the form of soil nailing, track… ∞
An existing access road to the Piethorne Water Treatment Works had started to fail, and tension cracks were observed in the road surface. PaSCoE were commissioned by Eric Wright Civil Engineering to design a temporary access track to maintain access for deliveries to the Piethorne & Wickenhall Water Treatment Works…. ∞
Bookham embankment is located between Effingham Junction and Leatherhead Junction. A section of the line is built upon an embankment up to 5.5m high with a slope angle of 31°. The embankment was constructed mainly using remoulded soft clay, and a circular slip failure had resulted in movement of the… ∞
Baystone Bank Reservoir impounded the Whicham Beck and the Whicham Beck tributary. The total catchment area at the dam was 2.47km2, with approximately 93% accounted for from the Whicham Beck and 7% from the tributary. The standard average annual rainfall for the catchment is 1,780mm. A by-wash channel allowed reservoir… ∞
A former sandstone and diorite quarry on a 16hectare site near Nuneaton was to be redeveloped by Redrow Homes for new residential housing. To maximise the available land required the construction of a new retaining structure within the existing quarry. The existing quarry comprised a partially flooded Main Void and… ∞
The existing embankment pre-failure comprised of a clay slope at an approximate inclination of 1:1.5, with a height of approximately 8m falling to a stream at the base of the slope. Road drainage was directed to a ditch at the side of the embankment falling to the stream at the… ∞
