COTTOBLOC is the registered trademark for the line of bricks and listels for outdoor paving. Made from 100% bioenvironmental natural clay with ANAB certification, all the products of the Cottobloc line are CE certified in accordance with the UNI EN 1344 reference standard. They can be used to lay surfaces suitable for vehicles and are durable, frost-resistant and nonslip, but above all they are elements of the highest aesthetic quality. Some formats have spacing lugs, which facilitate laying. In fact the projecting profiles on two lateral faces of the piece accelerate the work of laying the bricks with the recommended gap between them.
