EcoBloc Flex is a modular geocellular unit which is used as a below ground stormwater attenuation or soakaway tank. The EcoBloc Flex crates are designed to be stacked together to create a holding tank or to allow the infiltration of storm water into the ground. The void in the crate holds the stormwater during heavy rainfall conditions. 

The collected storm water then soaks away slowly into the drainage system or ground water table over a more sustained period of time. Extensive use of this type of storm water attenuation module has helped relieve pressure on surface water drainage systems in line with the Sustainable Urban Drainage Systems (SUDS) program.

great solution, fast shipping

I've used these to deal with storm water from a newly built shed. They're easy to use, lift, install etc. I'd highly recommend them. I bought from a very helpful and friendly company called tanks direct in Cork. They helped me to correctly work out what i needed and shipped the units and membrane quickly. All parts arrived early the next morning. Very pleased with this overall transaction.
