Fiberforce Extra top layer geotextile is used as a top later in commercial and public riding arenas. It is manufactured using both needle-punched and thermally bonded technology which gives performance properties that specifically suit their use in equestrian applications where silica sand riding surfaces and mixes are to be used. Fiberforce Extra acts as a separator, but more essentially prevents the small particles (e.g. silica sand) that form the riding surface, from migrating of into the aggregate layer below, and allowing free drainage without clogging to avoid the arena becoming waterlogged. With its very small pore size Fiberforce is ideally suit to equestrian applications.
