Storm crates are installed underground to prevent flooding and because they are designed to incorporate high structural strength, they can feature void ratios of up to 97%, offering enormous amounts of space and surface area through which water can infiltrate.
Use one of our soakaway crate systems to control and effectively manage excessive rainwater. Our storm crates are ideal for ground infiltration and have been fully tested for peace of mind. These storm crates operate as soakaway crates – meaning that they can allow water from the surrounding soil to seep into them, aiding soil drainage, and, more importantly, they allow the attenuated storm water to slowly soak away into the earth after it is collected. Once the storm abates, the ground will naturally begin to slowly release the water it has absorbed, allowing your soakaway crates to drain away at the same rate as the natural movement of groundwater. Thanks to this method of drainage, your attenuated storm water will not cause damage to the soil or cause flooding or waterlogging – it will simply soak away. We have a variety of storm crates that are lightweight and low maintenance, allowing you to spend your time wisely and more effectively!
