How Do I Work Out How Much Gravel I Need For An Area?October 11, 2016
One of the questions we often get asked as a merchant is: How do I know how much aggregate I’m going to need for this job? There are two ways of going about this.
OPTION 1 (the hard way): calculate it yourself according to a given formula.
On a driveway, for example, the gravel, stone chips or shingle should be a minimum of 4″ (100mm) deep. If stones are larger, say 40mm or more, you’ll need to have it deeper still. Then use this rough guide (courtesy of http://www.doityourself.com):
For stones 1/4″ to 1/2″ : 50 sq. ft. per ton
For stones 1/2″ to 1″ : 45 sq. ft. per ton
For stones 1 1/2″ to 2″ : 40 sq. ft. per ton
