The ABEM Terrameter LUND imaging system provides fast, accurate and automated resistivity imaging in 2D and 3D. |
ABEM's Terraloc Mark 6 seismograph has been especially designed for the full spectrum of shallow seismic applications. |
The VIBRALOC is an intelligent vibration monitor that analyses both vibrations and air shock waves. |

In Hampton, Peterborough, a Stren-Cor 6m span x 1.8m high x 60m long environmental tunnel structure. |
Multiplate MP200 galvanised arches protect cables for the Newport Southern Distributor Road (SDR) scheme - the tunnel is 103m long x 4.25m span with elbows. |
ASSET International's tunnel applications offer solutions to a variety of placements, from underground road tunnels for urban environments to environmental preservation passages for conservation projects. Here at the Port Talbot Peripheral Distributor Road (PDR) project, 43m long corrugated steel structure is used for a cycle path. |
An ellipsed Tunnel Liner Plate shaft, this can provide rockfall protection for mining applications. |
A2 / M2 Junction 4 widening: perforated MP200 Multiplate soakaways with depths up to 30m were used. |

The TRTX12 is a 12-channel FM in-tunnel rebroadcast system which rebroadcasts FM stations, on the same frequency, into two tubes of a road-tunnel system, via leaky feeders or other transmission mediums. |
The system includes an audio break-in facility for emergency announcements, and can be expanded from one channel to 12 channels or more with the addition of combiners, splitters and translators. |
The FM translator's performance is that of a high-end system with exceptional audio-distortion, signal to noise and spurious specifications, and it has a bandwidth of 100kHz. |
