12/29/2015

The rule is that the foundation should not reach below the groundwater level. If the water is shallow or very shallow – then a foundation slab weighted with an earthen embankment is most often used (or shallowly buried “mushrooms”, i.e. prefabricated foundations of the F series, e.g. manufactured by Elbud Gdańsk). Cast slabs are also often used when just below the ground surface in areas…

There are three main issues in the case of lightning protection of telecommunications masts that must be taken into account. In our opinion, the best and cheapest way to discharge the electric charge is through the structure of the mast or lattice tower. Alupro solutions are equipped with a special eyelet in the lowest segment that allows the whole thing to be connected to the building's lightning protection system. In the case of painted structures, remember to remove the coating…
