Nidagravel is very easy to install, follow this simple guide for a perfect finish.
Nidagravel 125 is quick and easy to install. Firstly you need to lay a foundation. Paths and pedestrian areas need only a layer of compacted sharp sand.
Nidagravel can be cut easily with a power or hand saw to conform to any shape required and numerous trays can be laid in a matter of minutes and subsequently filled with gravel.
The area needs to be edged to retain the trays and gravel, using:
• Existing buildings and walls
• Metal edging systems
The edging must be at least 60 mm proud of the top of the sand layer which forms the sub base. The trays are filled with gravel (25 mm tray thickness plus 10 - 20 mm overfill to conceal the trays).
As a guide using 10 mm diameter gravel, 1 ton should cover approximately 10 to 12 square metres. The thickness of the sub base is ependent on local ground conditions and the envisaged load, and should be tailored accordingly.
