Clevedon Marine Lake
A trip down to the seaside! TEC has been working down at Clevedon Marine Lake helping to investigate the condition of the existing roadway and wall, and the underlying ground conditions. Initially, non-intrusive techniques were used, including a GPR survey combined with an endoscope to assess for voiding. This allowed for more targeted intrusive investigation works to minimise disruption in this popular seaside destination.

Vivary Park, Taunton
TEC have recently completed a ground investigation in Vivary Park, Taunton Group. The existing bandstand, constructed in the early 1900s, was showing signs of movement causing damage to the walls and ironworks. The ground investigation and assessment focused on establishing the underlying ground profile and remedial designs for the bandstand. Not our usual kind of structure but an enjoyable change to help preserve such a picturesque historical feature.

This unique development is providing luxury, sustainable holiday homes, making use of the beautiful site setting complete with its own mineral lake and woodland glades. TEC has undertaken various works at the site over the years, predominantly looking at the ground conditions and slope stability during each phase of development.
