If you want to go deep make sure it's with the sub-base! It is recommended that a maximum depth of 50mm be applied as this provides good coverage of the sub-base whilst remaining shallow enough to prevent rutting. The gravel/shingle used on the driveway should be 20mm in size. Smaller sizes such as 10mm and 6mm should not be used for driveways as the smaller particles get stuck in car tyres and also provide a handy toilet for neighbourhood moggies!
1 A fridge should have a temperature of between 37Â°F(3Â°C) and 40Â°F (5Â°C). Any higher and the food will go off, any lower and youâll lose nutrients and fresh food can be ruined.  The ideal freezer temperature is 0Â°F (-18Â°C) which will store food safely and stop bacteria forming.
