Standards and regulations
Simplex piles are designed and manufactured in accordance with Eurocode 7 and DIN EN 12699 and the recommendations of the “Piles” working group (EA-Pfähle). Diameters range from 42cm to 61cm. Pile lengths of up to 40m are possible.
Simplex piles are in-situ concrete driven piles with a reclaimed driving tube. This is sealed from below with a watertight base-plate. The pipe is driven into the ground by a hydraulic hammer via the head. The driving work involved, measured in blows per metre, is a measure of the load-bearing capacity of the soil at the pile site in question. Once the desired depth is reached or the driving criteria are met, a reinforcement cage is installed, concrete is poured in and the casing tube is retracted.
