DESOI Piles

allow the realisation of foundations or foundation strengthening of a structure within very short time. The low weight and the easy installation enable the application in nearly all foundation grounds and at almost every place. The helical design of the DESOI Piles generates a unique ratio between cross section and total surface for a high transfer of the tensile and compressive forces into the foundation ground. The extremely corrosion resistant aluminium alloy permits the use in aggressive soil. As a result, even under the most unfavourable conditions a lifetime can be granted that exceeds the minimum working life of 80 years for permanent buildings. Micropiles DESOI Pile are 1m and available in two versions 60 and 100 mm, with different bearing load.

The installation of the DESOI Piles is carried out using hand-held or mini-excavator driven hydraulic hammers driving the pile into the foundation ground. Thus neither excavation nor earthmoving are required and nearly no vibrations are generated that may affect surrounding areas or buildings. Immediately after installation, the piles can be loaded. DESOI Piles are of multiple use and can be removed after the installation. In addition to making foundations for new structures, the piles are ideal for foundation strengthening of existing structures. The piles are available as 1 meter segments, in the nominal diameters 60 mm and 100 mm, and with different load bearing capacities.
The results of the pile load tests correspond with the calculated values in consideration of skin friction and end resistance for bored piles. For design, calculations taking into account the experienced data with a partial safety factor of h = 2.0 are applicable. An object-related load testing allows the application of lower partial safety factors as thereby possible errors and inaccuracies are omitted when the experienced values are transferred to the pile to be designed. The basis for a design are site investigations.
