A surface covering foundation includes a first covering element having a thickness and defining a first juxtaposition side; a second covering element having a thickness substantially equal to that of the first element and defining a second juxtaposition side, adapted to be juxtaposed with the first side, the first element having a lip that forms an outward extension of the first juxtaposition side and is adapted to overlap the second juxtaposition side in a juxtaposed configuration of the first and the second covering elements. |
