Does grass or weed grow in the joints of rubber granulate tiles?

In rubber granulate tiles connected by plastic connectors, grass and weeds can grow in the joints because this system creates a relatively wide gap extending down to the load-bearing layer. However, by bonding the tile edges during installation, this gap can be effectively closed. In tiles with a puzzle connection or a concealed puzzle connection, weeds generally do not grow in the joints when they are properly used and maintained. The joints are either too narrow to support growth or do not extend to the load-bearing layer. To prevent unwanted growth, the tiles and joints should always be kept clean.
