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.

Hard-working roofs

Roofs will have to work harder to meet the demands of sustainability, says Mike Crook, who argues that green roofing could provide the way forward.


If the green roof was once the domain only of environmental pioneers, it has now become a fact of mainstream construction. Long gone are the days when it was enough for a roof to waterproof a building, with added value because it provided effective insulation or contributed to the impact of a new design. Today a roof has to work much harder – and keep on working harder for decades.















There is a whole host of reasons for this, including:
• exponential population growth
(with most pressure on the core of densely populated urban areas);
• depletion of financial and energy resources;
• threats to the environment;
• legislative changes
