The specified values for the possible external load-bearing capacity were determined for soil: loam, semi-solid (TL; TM). The information is only given for a first selection of possible screw foundation types in the design level. The basis for a final foundation design are load tests on site as well as a static verification of the internal load-bearing capacity of the KRINNER screw foundations. The Construction Products Act, the Construction Products Regulation, other regulations of the EC and the respective state building regulations must be taken into account.
The F-series ground screws are equipped with round or square flanges. The fixation of the bearing object made possible by this ensures the highest possible stability and safety, even with large or extreme structural loads.
