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.
Normally a domestic freezer is best set to â18 Â°C (0 Â°F) or colder, as that's what the expiration dates for many food items are based on. It's also a requirement for freezers in restaurants, supermarkets & other places that sell food (at least here in Europe) to maintain a temperature of at most -18 Â°C.A general purpose domestic fridge should be at around 1-4 Â°C (so, just above the freezing point, and below 5 Â°C).n order to keep food out of the Danger Zone, your fridge must be set between 32-40Â°F (0-4Â°C). Your freezer must be below 32Â°F (0Â°C). I keep mine as cold as it will go.
