These systems allow you to work up to four times faster than conventional fastening methods. DX and GX usage does not require any electrical power and is therefore cordless. This provides each worker on the jobsite significant flexibility and safety. In conjunction with the new Clean-Tec cartridges, which have allowed Hilti to set a new standard for heavy metal cartridges worldwide, this underlines the environmental inno- vation that Hilti is striving to achieve. DX and GX fastening systems will allow more efficient, safe and environmentally friend- ly work to be carried out than ever before. Innovation Hilti develops innovative high performance fixings with close attention to the envi- ronmental benefits at an early stage in product development and right through the product lifecycle. Thus, the Hilti HVA resin anchor system and Hilti HIT-RE-500 are fully approved by the Water Regulations Advisory Scheme (WRAS) for use in contact with potable drinking water. Foams, firestopping and air sealing Furthermore, most Hilti foams and firestop products are dust-free applications. An example of this is cast-in products which are installed before the floors are cast. This means that there is no drilling necessary. The sustainability of sites is improved with Hilti products by supporting the following important characteristics of a building: movement capability, firestop and watertight- ness. Movement capability allows the tracing of building movement. Firestop proper- ties of Hilti products are tested to various worldwide standards to reduce damage due to fire, even during the building phase. Watertightness aids in avoiding jobsite damage due to water penetration, either through rain or during a fire. Thus, using Hilti tools and accessories can further improve the potential for BREEAM credits. page 11
