Less disruption and damage to surfaces worth conserving (road surface, water courses, railway embankments etc.) and minimal restoration – giving economic advantages Low social impact because, diversions, half-sided barriers, traffic signal facilities etc. are avoided Acknowlegded pipe installation technique Short setting-up times - short installation times The dynamic impact when ramming can shatter obstacles and easily overcome difficult starting resistance after standstill periods. The aiming accuracy is improved because the dynamic impact penetrates various soil formations within the diameter range and obstacles do not have to be displaced or pushed aside in one piece No jacking abutment, no auger cutter required, which could get jammed The soil core remains in the pipe during ramming, i.e. no rush of water when rivers or areas with a high water table are undercrossed Minimal ground covering, i. e. no large-scale pits Simple operating technique Adaptation to all pipe diameters with

Substitution of steel spring by S-Ply® leaf spring   Due to their  greater spring action, steel spring packages can be replaced by fewer or even one S-Ply® leaf spring for many applications.   Example:   a) Substitution   b) Cost calculation   Steel leaf spring: 155 x 25 x 2 mm 1 package of 10 springs   S-Ply® leaf spring: It is essential:   with: hS-Ply = Thickness of S-Ply® spring hStahl = Thickness of steel spring nStahl = Amount of steel springs EStahl = Modulus of elasticity (here 210.000 N/mm2) ES-Ply = Modulus of elasticity of S-Ply® leaf spring (here 28.000 N/mm2)   The result is that 10 steel leaf springs with a thickness of 2 mm each can be replaced by only 1 S-Ply® leaf spring with the thickness of 8,5 mm. Steel leaf spring* 10 pieces at 1,20 € = 12,00 € Intermediate package layers 18 pieces at 0,12 € = 2,16 € Total costs 14,16 € * purchase quantity > 1000 pieces, status 2009   S-Ply® leaf spring** 1 pc. at 4,13 € = 4,13 € shim plates (if applicable) 4 pc. at 0,12 € = 0,48
