Leader Rigs In recognition of the potential of pitch and drive pile-driving methods, we have invested in an RTG 19m sheet piling and three ABI Telescopic Leader rigs ranging in size from 17m to 14m - all with resonance-free vibratory hammers. This high output equipment can be rapidly mobilised, erected and folded down and emits reduced noise and vibration, allowing piles to be installed in sensitive environments. Kowan Silent Pilers We own and operate a fleet of environmentally-friendly silent pilers to install 400mm, 500mm and 600mm steel sheet piles on a pitch and drive basis. By pushing hydraulically, they produce zero vibration, minimal noise and are easily mobilised to and around sites. Driven Bearing Piles Dew Piling have invested in two Junttan PM20LC leader rigs equipped with 5 tonne accelerated hammers.  These versatile self contained rigs are ideally suited for the installation of precast concrete or steel bearing piles on large or small developments. Conventional Sheet Piling We own and operate a fleet of conventional hydraulic drop hammers which can be adapted to drive sheet, tubular and 'H' section piles. Both standard and resonance-free vibrating hammers and extractors are available. Where air hammers are the only solution to a specific driving problem, we can provide 'N' series hammers as required. Chowa CHV400 Dew Piling has jointly developed the new CHV400 Vibromaster to provide versatile and powerful installation of 600mm wide U section sheet piles, Z section sheet piles upto 620mm wide and H pile sections upto 400mm.  The new machine has the flexibility and long reach to install piles in even the least accessible locations.  It has been designed to generate low noise and vibration compared with the alternatives. CFA Piling Dew Piling now offers Continuous Flight Auger (CFA) Piling which is low noise and vibration free compared with Driven Piling.  CFA piles are installed using Soilmec CM48 and CM50 for pile diameters between 300mm and 600mm diameter.  Soilmec R625 and Juntann 18-30 machines are used for installation of piles with diameters between 600mm and 900mm and bored displacement piling.
