The latex rubber is mixed with sand for making flexible facing bricks. These bricks were submitted to tests (flexibility test, lengthening test and usury resistance) and the microstructure studies to determine their mechanical performances and understand the effects using the latex rubber in the bricks. Bricks flexibility increases on the upper side when the latex content grows up to 16 %. It passes through an optimum at 16 % of latex before decreasing. On the other hand underside flexibility of the bricks increases with increasing latex content. Usury tends to be canceled with 18 % of latex. Strengthening the sand with the latex also shows that bricks have the ability to grow until 12 % and can resist to a maximum load of 65 N. The latex can link and coat progressively the sand particles. Microscopic observations of the bricks shows a variation of the structure of composites according to the latex ratio. It gives a good coating of sand particles with latex from 16 % with more related interfaces between 10 and 15 % of latex.
