The Philippine government's public works department believes its new Italian-sourced under bridge inspection unit will offer "complete safety" during structural investigations. The ABC 110/L from Barin, based in Cittadella, north east Italy, has a 2-Axle Volvo FLL 240 42R Chassis and occupies just one road lane, to enable continued traffic flow. The machine has a bridge barrier clearance of 2.25m, a path clearance of 2m and a horizontal outreach underbridge of 11m. With a vertical depth underbridge of 6.60m

Naue Geosynthetics says its Secugrid offers a solution for a host of ground preparation problems, and for use in reinforced retaining walls. Secugrid is a geogrid made from extruded monolithic flat bars with welded junctions, for soil reinforcement in earth, landfill and road construction as well as in hydraulic engineering applications. Among its benefits are said to be its high strength and low elongation thanks to the extruded elements. "The monolithic flat bars give it a robust construction, an

Colbond, a leading producer of synthetic nonwovens and polymeric mats and composites, has appointed Jan Mahy as global director of research and development. He brings with him 18 years of professional experience and moves from Akzo Nobel, a former parent company of Colbond. "I am looking forward to join Colbond's vision to strengthen the company's postition as an innovative global player in technical textiles. Leading an international group of experts to develop and improve products for this industry

Demand for geosynthetics in the United States alone is projected to increase 4.4% per year through to 2010 to more than 727 million m². Geosynthetics, used worldwide in the highway sector for strengthening, include geotextiles, geomembranes, geonets, geogrids, geosynthetic clay liners, preformed geocomposites, geocells and geofoams. The US advances will be fuelled by a recovery in nonbuilding construction. Additionally, geosynthetics will continue to increase their use in a wider range of applications

An innovative new product, SD605, is said to help boost safety by cutting dust levels during manufacturing of pre-cast concrete products. The US-developed product can also be used for dust control in construction, roadway, haul road, erosion and soil stabilisation applications.

The powerful and productive DXB breakers from Doosan are said to suit a wide array of applications such as tunneling, secondary reduction, primary winning and demolition.

Infrastructure has been chosen to provide a sealing system for the world's longest immersed tunnel. China Communications Construction is said to have selected Trelleborg for the innovative design of its seals, which are claimed to ensure watertightness even through a seismic event. Part of China's prestigious Hong Kong - Zhuhai - Macau link project, the immersed near 6km tunnel will consist of 32 elements. The joints will be sealed with a Trelleborg sealing system including Gina gaskets, Omega seals and wat
