The surface needs to be compacted and leveled, with a finished smooth surface to install the tiles. Crushed stone is a common installation surface for outdoor rubber playground tiles. A crown on the surface for water drainage is also recommended.
how does one keep these lock over time. because it looks like its strinking and the seams are 2'' apart out on the playgrounds. its causing a tripping hazard.
The tiles are generally glued down to stay in place and the seams can also be glued, installation instructions are available on this product page.
Can this be installed over dirt? It is currently a grassy area that will be ripped out with only dirt remaining.
3 inches of crushed stone is recommended as a proper base with a geo mesh cover before the rubber tiles are installed.

The material is recycled rubber tires, we dont claim any safety beyond fall height ratings, its an outdoor rated product.
