Soil Protection from Stormwater Runoff, Erosion And Channeling
Neoloy® Geocells provide a sustainable drainage system (SUDS) or advanced stormwater management technique for the localized control of stormwater
The Stormwater Management Challenge
Neoloy Geocells are a sustainable drainage system (SUDS) or water management technique for the localized control of stormwater. Neoloy cellular confinement preserves the soil structure, tolerates high sheet-flow conditions and is self-draining for high infiltration into the soil.
Stormwater runoff, once considered a nuisance to be removed of as quickly as possible, is now considered a resource to be managed locally, close to where it hits the ground. The idea is to reduce the impact of built areas and promote the natural movement of water on-site by harvesting and infiltration to underground water sources.
Today’s planning policies and construction guidelines mandate water strategies based on integrated water management to seeks to mitigate the impact of surface water discharges, improve runoff quality, reduce the risk of flooding and augment potable water resources.
The Neoloy Solution for Stormwater Management in Pavements
Neoloy Geocells integrated in the structural layers of concrete paving block systems can best reduce stormwater by maximizing infiltration in structural layers, thereby reducing runoff and flooding and filtering pollutants. The high Neoloy Geocell reinforcement factor enables the use of open grade aggregate, which has lower strength than engineered stone, but greater permeability.
The Neoloy Solution for Stormwater Management in Slopes and Channels
Neoloy Geocells preserve the soil structure, tolerate high sheet-flow conditions and are self-draining for high infiltration into the soil.
Neoloy Geocells are also ideal for soil protection of contoured open-channel gravel drainage ditches and bioswales used to manage stormwater runoff. They prevent soil erosion and channeling while providing an excellent growth medium for the growth of turf and vegetation, or preventing aggregate movement in gravel ditches. This assists the on-site infiltration to reduce runoff, filter pollutants, prevent flooding and augment underground water resources.
In addition, Neoloy Geocells stormwater management systems can be used with permeable pavement systems, such as concrete paving blocks to enhance pavement drainage.
