Geotest can carry out three types of test:
Geotest use a range of hollow hydraulic cylinders designed to fit any diameter anchor to apply the pressure.
Accuracy is essential! - Geotest use a fully calibrated load cell to monitor pressure on the hollow cylinder. This is far superior to a pressure system where hydraulic oil pressure in monitored which can vary significantly over time.
Geotest can test vertically, horizontally or at any angle between. A hard surface is desirable to jack against, however is not always essential.
Geotest have carried out testing on a range of sites including:
Geotest carry a selection of fittings / extension bars, and can obtain fittings / bars to fit most types of anchor. Please call us to discuss your anchor system and see how we can help.
Non-Destructive soil nail testing at a former mining site in Cornwall. The works were carried out on behalf of a contractor as part of a multi-million pound regeneration project. Every anchor was tested and locked at the required tension.
Rock bolt testing was carried out on a small, cliff-side dwelling in Devon. The works were carried out on behalf of a contractor as part of an insurance subsidence claim. All anchors were tested and locked at the required tension.
Anchor testing was carried out at a dry dock in Cornwall, where a major private developer was installing a structure to cover the dock. Initially destructive tests were carried out on the concrete slab adjacent to the dock. A second round of non-destructive testing was then carried out on the anchor point for each column.
Destructive testing of test piles at a former power station in Cornwall for a private developer. Test piles were required to prove bond strength between the pile and the steel reinforcement bar.
Completed rock bolts on a site in South Wales for a private developer. Initially work involved overseeing installation, on behalf of the project engineer. Geotest were later asked to carry out non-destructive testing of the rock bolts, and to tension each to the required load.
Anchor testing was carried out on night shifts, beside a major trunk road in Devon. The works were carried out on behalf of a major contractor, acting on behalf of Highways England. An initial round of destructive testing was carried out on test anchors, to establish the required grout bond strength. A second phase of non-destructive testing was then carried out on selected anchors to establish suitability prior to the installation of safety barriers.
Testing of ground anchors was carried out on a difficult access site in Cornwall, for a contractor working on behalf of the local authority. Selected anchors were non-destructively tested after installation. The site was challenging because of ‘working at height’ and special precautions were required to protect the technicians.
