Product Weights & Volumes

Also check out the Deliveries FAQ page.


Below you will find tools and information to help you calculate volumes for your project. 


If you are collecting materials with either your own trailer or a hire trailer you will need to recognise the weight limitations of your trailer and car combined. Your car's limitations are set out in the manufacturers manual. 

Some basic guidelines:

  • a car trailer combo is required by law to be able to stop within 7 meters from 30kph
  • as a rule unbraked trailers are limited to 750kg (trailer + load)
  • your towbar will specify your braked and unbraked limits for your vehicle
  • belling tires, leaf springs depressed to horizontal or beyond and wheels tilting inwards are all signs of trailer overloading

Product listings will have their estimated weight per cubic meter shown at the bottom of the listing. If unsure please call the office or talk to our loader operators when collecting.

How to estimate volume based landscape products

In this example, we want to calculate the required quantity, weight and cost of garden soil. As you can see, we cannot just type the width and length into our dirt calculator as there is a pool in the middle of it. How to deal with this problem?


There are two methods for the above example. 

1/ As a simple rectangle we can simply measure the width and length of the entire yard - multiply these two numbers to obtain the square area of the yard then do the same for the pool. We then subtract the pool from the yard total.

EG - Yard 25 x 7.7 = 192.52

         Pool 12 x 3 = 362

         Total 192.5 - 36 = 156.52

2/ If you have more complex shapes, the easiest method is to break the shape up into squares and/or triangles or use a grid method. See examples here

The above example breaks the shape into squares which can then be calculated and added together to find the square area. 

When deciding on depth this can be difficult if the depth will vary across the area being considered. If it is not a uniform depth then you will have to estimate the average depth as best you can.

Note: You should allow for compaction and shrinkage with depth estimates. Allow at least 20%. If your depth is 100mm add 20mm (120mm).
