These mats are basically all-rubber mats with holes! They are used for a variety of purposes and are available in different sizes and styles. As an anti-poaching mat for horses, the mats can be laid onto grass and will offer a non-slip surface that helps against 'poaching' - particularly useful in gateways or for walkways. The same mats are also used for wet areas or wash-down areas for animals, enabling the free flow of water away from horse and groom while giving a safe footing for both. Laid onto grass in a play-area, also offering a good anti-slip surface.
