How much area does a ton (bulk) bag of gravel cover | what area will a bulk bag of gravel cover | what surface covered with a ton of gravel | how much area will a bulk bag of gravel cover.

A ton bag of gravel also known as bulk bag, jumbo bag, dumpy bag, or tonne bag, which weighs about 875kg, and yields volume about 0.5m3, and which covers around 10 square meters (m2) at standard thickness of 5cm (5mm).

If you want to estimate the required quantity of gravel, chipping, pebbles or cobbles for your driveway, pathway, patio or for your planting area, you should know the dimension of your projects, what is their area and how your depth should be.

Calculating the total amount of gravel you will need for your pathways can sometimes be overwhelming. So for help, this article will provide you easy calculation methods for amount of gravel you will need for your project. We know about what area will a ton bag of gravel cover, by knowing this you can make an estimate and how to calculate the amount of gravel you will need for your project.

Landscaping materials such as gravel, chipping, pebbles, or cobbles are used to fill your pathways, driveway, patio or planting area. As per practices, gravel are sold in different bag size, small size of 25kg bag, 20kg bag, and large size of 875kg bag which are also known as ton bag, jumbo bag, Bulk bag or tonne bag.

A cubic meter of typical gravel, chipping, pebbles or cobbles weighs approximately 1,680 kilograms 1.68 tonnes. A square meter of gravel with a depth of 50 mm weighs about 84 kg or 0.084 tonnes. But for estimate purpose, contractors and builders would take 1750kg/m3.

### How deep should you go?

If you choose a 10mm aggregate such as Premium Quartzite Pea Gravel 10mm or Cottage Cream Gravel 10-20mm, you may want to lay it to a depth of around 30-40mm. If, however, you are buying gravel or granite chippings for driveways, you will probably need to lay it up to a depth of around 50mm-60mm.

If you decide to use a 20mm aggregate, you would probably be looking at laying to a depth of around 40mm-50mm. This would rise to around 50mm-60mm if you are planning a driveway.

### How much area does a ton bag of gravel cover

As per general rule of thumb, a ton bag (bulk bag, jumbo bag, dumpy bag, or tonne bag) of gravel will cover approximately 10 square metres (10m2) area at recommended depth of 5cm (50mm) thick, and 16 square metres (16m2) at 3cm (30mm) thick.

To calculate how many square meters area will cover by a ton bag of gravel, divide yields of a ton bag (0.5m3 volume) of gravel by thickness in meters to get a ton bag gravel coverage in square meters.

At 5cm, A ton bag of gravel coverage
● Thickness 5cm in m = 5/ 100 = 0.05m
● A ton bag of gravel yields = 0.5m3
● Gravel coverage = 0.5m3/ 0.05m = 10m2
● Thus, gravel coverage 10m2 at 5cm.

At 3cm, A ton bag of gravel coverage
● Thickness 3cm in m = 3/ 100 = 0.03m
● A ton bag of gravel yields = 0.5m3
● Gravel coverage = 0.5m3/ 0.03m = 16m2
● Thus, gravel coverage 16m2 at 3cm.

At 4cm, A ton bag of gravel coverage
● Thickness 4cm in m = 4/ 100 = 0.04m
● A ton bag of gravel yields = 0.5m3
● Gravel coverage = 0.5m3/ 0.04m = 12.5m2
● Thus, gravel coverage 12.5m2 at 4cm.

At 6cm, A ton bag of gravel coverage
● Thickness 6cm in m = 6/ 100 = 0.06m
● A ton bag of gravel yields = 0.5m3
● Gravel coverage = 0.5m3/ 0.06m = 8m2
● Thus, gravel coverage 8m2 at 6cm.

Conclusions:
As per general rule of thumb, a ton bag (bulk bag, or tonne bag) of gravel, will cover approximately 10 square metres area at recommended depth of 5cm thick, and 16m2 at 3cm thick.
