Aggregates & Screed Calculator

We know that calculating your amounts can be a time consuming and frustrating task when taking on a new project, so we’ve created this calculator to make the process as quick and easy as possible for you.

1: Select your aggregate or screed type

2: Using your chosen unit, enter the length, width and depth of your space

3: Calculate and get building!

Same or next-day delivery is available on aggregates within a 20 mile radius, but make sure you order early to ensure you get a slot.

How long will my screed take to dry?

Standard screed will, on average, dry at a rate of 1mm per day. This means that if your screed is placed at a depth of 50mm, it will take approximately 50 days to fully complete the drying process and be ready for a finish to be applied. Generally, allow for foot traffic 48 hours after initial application.

You will need: tonnes of this aggregate type.

You will need: large pacs (25kg) of this aggregate type.

The exact conversion depends on a number of factors beyond our control, for example moisture, method & degree of compaction, type of sub-base etc. We cannot be held contractually responsible for any surplus or shortfall found on site.
