Geocellular Confinement


Geocellular Confinement takes infill materials and produces a stiff base by creating a semi-rigid slab. The system prevents the lateral displacement of infill materials which eliminates rutting and washboarding usually associated with gravel pavements. The system allows for a reduction in overall base thickness, as well as enabling subgrade materials to withstand more than 10 times the number of cyclic load applications, without the appearance of deflection when compared to unconfined aggregates. GCS allows for the use of lower quality infill materials in situations where quality aggregates are not readily available and helps to create pavements on soft soil subgrades. When it comes to load support in porous paving applications, Cell-Tek's LSG SERIES delivers the competitive advantage.

New Stormwater Rule will impact construction industry

On December 1, 2009, U.S. EPA published effluent limitations guidelines and new source performance standards to control the discharge of pollutants from construction sites. U.S. EPA expects that the New Stormwater Rule1 will reduce the amount of sediment discharged from construction sites by about 4 billion pounds each year. Importantly, the U.S. EPA also estimated the annual cost to comply with the New Stormwater Rule to be approximately $953 million after the rule has been fully implemented.

Erosion, Sediment Control and Soil Stabilization Requirements
This new rule also establishes general erosion and sedimentation control requirements that will apply to all those operators seeking coverage under the stormwater NPDES program (non-numeric requirements). The non-numeric requirements become applicable within 60 days after the final rule is published in the Federal Register, which was February 1, 2010. The non-numeric requirements include provisions related to designing and installing erosion and sediment controls, soil stabilization, dewatering, pollution prevision measures, prohibited discharges and requirements related to surface outlets.

    Another way to help reduce the flow of contaminants is by using a curb inlet filter.
