After the first row, we recommend the assembling of the elements in groups of three rows, which is foolowed by the concreting up to the middle of the topmost row of elements. Of course more skilled executors may concrete a wall as tall as a storey, provided that they have adequate support. For filling in use at least C16-20KK concrete. When placing concrete, protect the elements from damage and scattered concrete: cover them with a 2 m long downspout, cut in half lengthwise, or with a U-profile used for the installation of plasterboards.
