How many soakaway crates do I need?

Installing soakaway crates will help control the level of surface water in both domestic and commercial projects. This is particularly important in areas prone to heavy rain or flooding. This guide will help you to understand how many soakaway crates you need for your project.

Soakaway: By wrapping the soakaway crates in a permeable geotextile, water is allowed to slowly filter out into the surrounding earth at a steady rate. The slow rate of release helps to protect against flooding and stagnant surface water.

Attenuation: The addition of a waterproof geotextile and pipework redirects the water to a local body of water or existing sewer network. The installation of a filter controls the flow of the water, thereby protecting against the risk of flooding.

How many soakaway crates do I need?

How many soakaway crates you need will depend on variables including 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.

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 how many crates your system will need. Here at Drainage Superstore we have a number of soakaway crates to choose from:

Product No. of crates per m3
ACO StormBrixx Soakaway Crate 2.28
DYKA Rainbox 3S Soakaway Crate 3.3
Stormcrate Soakaway Crate 3.3
Polypipe Polystorm Soakaway Crate 5

 

With so many variables, it can be difficult to know how many soakaway crates you need for your project. Our drainage experts will be able to offer you advice and recommendations based on your requirements and preferred materials.
