The PMH-Hall is anchored using slightly different methods, depending on the ground conditions prevailing at the site where the hall will be erected. As standard, shorter span widths are anchored with double anchor irons, at each leg, which are driven approx. 1 metre into the ground. Larger span widths are anchored with ground anchors that are driven down and where an anchor is folded out underground to guarantee that the design lifting forces are obtained.
If there is uncertainty regarding the relevant ground conditions, a tensile test can be performed, where we can see what anchoring method will be best on this substrate. Apart from these alternatives, which are suitable for gravel and asphalted surfaces, the PMH Hall can be anchored on a cast concrete slab or a concrete base. In which case, the anchoring is performed with embedded groups of bolts or expanders/chemical anchors. As an option, we can deliver a prefabricated base that is put in place in connection with other the site preparation works.
