Such concrete blocks though smooth and decorative are used to build load-bearing walls. The smooth texture allow for a perfect finish. Finishing blocks are decorative elements of great beauty, suitable for the construction of all types of facades and fences. The white and coloured pieces are waterproofed. The pillars are essential when building any wall, as these make possible the joining of different sections, giving strength and stability to the whole, bearing much of the burden of it and transmitting it to the foundations.
