On the geotechnical trail

CIVILS 2005 - Catch up with the latest geotechnical developments with a tour through the Civils show.

Geotechnical exhibitors at Civils 2005 will be easily identifiable - all will be on the Geotechnical trail, labelled with a special 'green g' logo (as above) and picked out in green in the show guide listing.

Here is a sample of what you can discover: ABC Anchors will be showing its new addition, the ABC 350 lightweight anchor driver, designed to install helical screw anchors up to 3,500NM with a capacity up to 100kN.

One of the many developments on show at Civils from Dywidag Systems will be its segmental ductile iron pile. Sections are connected by a spigot and socket joint, which is quick to use and offers a high degree of stiffness. The piles are installed with a hydraulic excavator fitted with a jack hammer.

Screwfast Foundations will be introducing the Angel Pile at Civils. The system has been used to support signals for Network Rail and CCTV cameras for the Highways Agency. It can be used in poor ground conditions where multiple piles or a large gravity base would have been needed in the past. The wing section is driven with a hydraulic pecker as a sleeve over an installed Screwfast pile.

Ground improvement contractor Conform will be focusing on its new mobile batch plant and its innovative E-Found foundation. E-Found involves adding lime to marginal soils, particularly weak and desiccated ones, and compacting them to provide ground strong enough for pad foundations. The system was recently used on a contract for Wimpey Homes.

At Civils, Cofra UK will be explaining how its GeoflexR PVC sheet piles are an acceptable alternative to other sheet piling systems. And Uretek will be demonstrating its understanding of floor lifting and deep injection technologies, both resin injection processes for ground strengthening which provide a fast, effective and relatively non disruptive alternative to piling.
