When determining the number of crates you need to use for a soakaway crate system you need to take into account the many variables. Here’s a guide to the things to consider.
Variables you need to consider
How many soakaway crates you need will depend on variables such as space available, soil type and incoming/outward flow rate.
A groundworker or installer can perform a percolation test on the soil to determine the ground conditions. For example, clay-based soil is heavy and can cause water to filter out slowly, rather than draining freely. This test will give the area in square metres required, and hence how many soakaway crates.
Soakaway crates are modular, meaning they can be stacked on top of or next to one another. Each soakaway crate is a different size, therefore the brand you choose can determine the number of crates required for your attenuation system.
Always seek approval
It’s recommended that you should always seek approval from your local planning authority prior to commencing any works as often soakaways will need to be built with a specific design storm and duration.
