In particular, in the EGB 2000® sheet, apart from the impressions, the dovetail ribbing provides maximum adherence between the sheet and the concrete.
The loft system is completed by the application 2 cm from the concrete extrados of an electro-welded net, whose standard dimensions (minimum) are provided afterwards and whose function is load distribution and inhibit the formation of cracks.
