Walking, wheeling a bike and pushing a buggy are far easier on Nidagravel than on normal gravel. It uses a special system that involves laying gravel on polypropylene sheets with a honeycomb structure. The sheets are laid on a suitable sub-base, and gravel is then spread on top, making them invisible. The surface is porous, so there’s no need for special drainage systems, and the fibreglass membrane prevents weeds from growing through. You are, however, advised to regularly inspect the top layer to ensure there’s sufficient gravel sitting above the sheets to avoid them being in direct contact with cars. The system is able to handle frost, but, if a snowplough is used, make sure the top layer of gravel isn’t scraped off.
