# How much MOT Type 1 do i need? Calculation

The amount of MOT Type 1 you need depends on the area of project you intend to cover and the depth you want to achieve. MOT Type 1 is typically used as a sub-base material for roads, patio, driveways, and paths.

To calculate the amount of MOT Type 1 you need, you’ll need to measure the project area to be covered and determine the desired depth of the MOT Type 1 layer. Then, multiply length, width and depth to calculate the volume of material required.

MOT Type 1 is a granular sub-base material used in construction projects, particularly in road and pathway construction. It’s a mixture of crushed concrete, rock, gravel, limestone, gritstone, granite and sand. It has load bearing capacity, drainage properties and stability. It can distribute weight of vehicles and structure, and reduces the water related damage.

Mot type 1 is typically used to provide a stable foundation for roads, driveways, and other paved surfaces. MOT Type 1 is specified by the UK Department of Transport’s specifications for highway works. It’s designed to be compacted to create a solid base that can withstand heavy loads and provide good drainage.

The density of MOT Type 1 sube-base is typically about 2.2 tonnes (2,200kg) per m3 compacted, or 1.85 tonnes (1,850kg) per m3 loose, while the density of MOT Type 3 sube-base is typically about 1.85 tonnes (1,850kg) per m3 compacted, or 1.6 tonnes (1,600kg) per m3 loose.

A bulk bag of MOT Type 1 sube-base weighs approximately 800kg and has specific weight about 2,200 kg/m3 compacted or 1,850 kg/m3 loose, and yields volume about 0.4m3 and each bag will cover about 10m2, when laid at 40mm deep.

A tonne bulk bag of MOT Type 1 sub base weighs about 1,000kg and will typically cover 10m2 (10m x 1m) at a depth of 50mm. Its consists of crushed concrete, bricks and rocks; a mixture of hard stone, sand, aggregate limestone, granite and gritstone.

The standard dimensions of a typical one-car driveway is approximately 3.1 meters wide and 3.6 meters long, while a typical two-car driveway is approximately 6.2 meters wide and 7.2 meters long. In addition, the standard dimensions of a typical three-car driveway is approximately 9.3 meters wide and 10.8 meters long.

A gravel driveway should be at least 20cm or 200mm deep, including the sub-base. If using 20mm gravel, we recommend a depth of at least 5cm or 50mm for the gravel layer, and a depth of at least 15cm or 150mm for an MOT Type 1 sub-base.

## How much MOT Type 1 do i need?

To calculate the amount of MOT Type 1 sub-base you need you’ll need to follow these steps:

1. Measure the length and width of the driveway in meters. Assume a typical two-car driveway is approximately 6.2 meters wide and 7.2 meters long
2. Determine the desired depth of the sub-base needed. Assume depth of at least 15cm or 150mm for an MOT Type 1 sub-base.
3. Estimate volume of MOT Type 1: Multiply length, width and depth driveway, such as required volume of MOT Type 1 = 6.2 × 7.2 × 0.15 = 6.7m3.
4. Estimate tonnes of MOT Type 1: Formula are, cubic meters of MOT Type 1 x 2 = Tonnes for compacted , so 6.7 × 2 = 13.4 or nearly 14 tonnes.

Therefore, you will need approximately 7m3 or 14 tonnes of MOT Type 1 for 1-car driveway, while a typical 2-car requires about 14m3 or 28 tonnes of MOT Type 1. In addition, for a typical three-car driveway, you will need approximately 20m3 or 40 tonnes of MOT Type 1 sub-base.

### How much MOT Type 1 per square metre for a driveway?

Typically you will need approximately 0.25 tonnes (250 kg) of MOT type 1 for a 1 square metre area of driveway at 150mm deep. This should be applied in two layers of 75mm thickness and compacted using a vibrating plate.

### How many square meters does a ton of MOT Type 1 cover?

A tonne bulk bag (1,000kg) of MOT Type 1 will cover approximately 4 square metres area at 150mm deep, make sure you compact your sub base in layer of 75mm.

### How many cubic meters in a bulk bag of MOT Type 1

The volume of a bulk bag of MOT Type 1 can vary depending on the, composition, size and specifications of the bag. Typically, a bulk bag of MOT Type 1 aggregates is around 0.4 to 0.5 cubic meters in volume.

### How much mot type 1 do i need for a patio

For most patios, spreading a 100mm layer of MOT Type 1 sub-base on top of the soil will give you a suitable foundation – once compacted. As a general rule, an ideal patio sub-base depth should be consider as 100mm deep.

When you are preparing the sub-base for your patio, 1 tonne of MOT type 1 will cover about 5m2 at 10cm deep, so, therefore, you’ll need approximately 0.20 tonnes of MOT type 1 sub-base per square metre.

In general, you will need approximately 1m3 or 2 tonnes of MOT Type 1 for 3m x 3m patio, while a typical 4m x 4m patio requires about 1.6m3 or 3 tonnes of MOT Type 1. In addition, for a typical 5m x 5m patio, you will need approximately 2.5m3 or 5 tonnes of MOT Type 1 sub-base.

### How many bags of MOT Type 1 do i need

To determine the number of bags of MOT Type 1 you need, you’ll need to know the area you intend to cover and the depth you want to achieve. Multiply all measurements to calculate volume, and divide the total volume by the coverage per bag to find out how many bags you need.

For example, if your area is 5 meters long, 4 meters wide, and you want a depth of 0.1 meters, and each bag covers 0.5 cubic meters: volume = 5m x 4m x 0.1m = 2 cubic meters, bulk bags needed = 2 cubic meters / 0.5 cubic meters per bag = 4 bags.

The MOT Type 1 are supplied in a bulk bag of 850kg approximately and in mini bag size of 25kg. As a rule of thumb, a bulk bag of MOT Type 1 will cover an area of 10m2 to a recommended depth of 50mm, while a mini 25kg bag yields volume about 0.0125m3 and will cover an area of 0.25m2 to a recommended depth of 50mm. In addition.

### How many bulk bags of MOT Type 1 do i need

To determine how many bulk bags of MOT Type 1 you need, you’ll first need to calculate the volume of the area you want to cover with the MOT Type 1 material and divide the total volume by the coverage per bulk bag to find out how many bags you need.

For example, if your area is 5 meters long, 5 meters wide, and you want a depth of 0.1 meters, and each bulk bag covers 0.5 cubic meters: volume = 5m x 5m x 0.1m = 2.5 cubic meters, bulk bags needed = 2.5 cubic meters / 0.5 cubic meters per bag = 5 bulk bags.

### How many tons of MOT Type 1 do i need?

To calculate the amount of MOT Type 1 you need, you’ll need to consider the depth you want to cover and the area you’re planning to cover. Multiply all measurements to calculate volume, and multiply the total volume in cubic meters by the 2 to figure out how many tons you need.

For example, if your area is 5 meters long, 4 meters wide, and you want a depth of 0.1 meters, and each ton covers 0.5 cubic meters: volume = 5m x 4m x 0.1m = 2. cubic meters, tons of MOT Types 1 needed = 2 cubic meters / 0.5 cubic meters per bag = 4 tonnes.

Conclusions:
The amount of MOT Type 1 you need depends on the area of project and the depth you want to achieve. Typically, you’ll need about 0.1 bulk or tonne bags (85 to 100kg) or 4 x 25kg mini bags of MOT Type 1 sub-base per square metre at 50mm deep.
