How many soakaway crates do I need from Roofing Superstore?How soakaway crates work

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.

Speaking of flooding, did you know we have solutions for flood defence? Check these out to further improve the quality of flood prevention for your system.

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, which is why we’ve created a dedicated buyer’s guide for soakaways to help you out.
