The Gravel mat KM30 This is the perfect solution for creating gravel paths and surfaces that are always accessible and drivable. The KM30 gravel grid enables highly stable and unsealed surface design under all weather conditions. Even during heavy rain, rainwater is immediately channeled into the ground. This reliably reduces the localized accumulation of rainwater in a natural way. However, the smallest grain size should not exceed 20 mm.
Gravel mats are very popular with DIY (do-it-yourself) homeowners because they are incredibly easy and quick to install, even as a sub-base. Gravel mats are one of the most robust gravel grids (gravel honeycombs/ground honeycombs) for the sustainable stabilization of gravel with gravel, chippings, or crushed stone.
Thanks to the extremely water-permeable, micro-perforated levelling plate of the gravel grid, the natural drainage properties of the bulk material are fully preserved. At the same time, the levelling plate of the gravel grid prevents any gravel from penetrating beneath the grid and migrating into the subsoil. The highly resilient cell structure on the top of the gravel grid secures the gravel against lateral slippage, thus maintaining an even distribution of the gravel within the gravel grids.
Due to the unique construction of the gravel grid, there is hardly any other product with comparable properties. The micro-perforated levelling plate and the gravel cells are seamlessly and inseparably cast from a single piece. The levelling plate of the gravel grid is many times more robust, durable, and water-permeable than any nonwoven fabric.
This eliminates additional installation costs and the effort required for a nonwoven fabric. 16 connection points per gravel grid panel allow the individual gravel grids to be firmly connected to one another, thus creating a dimensionally stable overall surface. Without this connection technology, individual gravel grids could lift or sink, or even risk sliding apart. The optimal grain size for the gravel grid should be between 5 mm and 16 mm. However, the maximum grain size should not exceed 20 mm.
