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.

Baltimore's green success stories

April 22, 2010 - by Donna M. Owens - http://weblogs.baltimoresun.com/

Happy Earth Day! To celebrate, we bring you a sampling of green success stories: local residents and businesses, nonprofits and municipal agencies, all of whom are trying to make the Baltimore area a little greener, a bit more livable.

What: Northwest Honda
Where: Owings Mills
Earth Philosophy: A car dealership with an eco-friendly vibe

If you coax him, you might get Ed Dreiband to climb a narrow ladder, open a steel hatch and stand on the roof of his dealership. From this vantage point 25 feet above busy Reisterstown Road, Dreiband can survey 29,000 square feet of roof — and its 57,000 living, growing plants.
The green roof is the centerpiece of Northwest Honda’s eco-friendly auto facility, which opened in 2006. Its features include insulated glass panels, automatic sensors that control lights, and carwash bays that recycle upward of 3,000 gallons of water daily. “The roof is beautiful, especially in May when everything’s blooming,” Dreiband says of the tiny, drought-tolerant plants (most are a hardy species known as sedum). Green roofs can help reduce, filter and cool stormwater runoff. That in turn can protect sewer systems and watersheds. The roof makes Dreiband happy. “I have kids and grandkids, and I am thinking of them. We have one earth, and we all have to share it.”
