Neoloy® Geocells Provide Reliable Ground Stabilization & Reinforcement Of Soft Soils
Improving bearing capacity via Neoloy Geocell’s ground stabilization solutions is key to developing durable pavements over soft soils.
You can’t build or expand a road, railway or embankment over soft soils without subgrade ground improvement measures to improve its bearing capacity.Neoloy Geocells ground stabilization method provides an ideal subgrade foundation improvement solution for roadways, embankments and working platforms over unstable subgrades, such as soft sands, saturated soils or expansive clay soils. Neoloy Geocell’s ground stabilization improvement design at the subbase-subgrade interface stabilizes weak subgrade soil and increase its bearing capacity by several factors. Neoloy Geocell’s ground reinforcement increases the performance and lifespan of any roadway. Neoloy also enables a reduction in the thickness of structural layers by 50% or more, and the use of local, marginal granular soil and sand for structural infill.
Made from high-modulus novel polymeric alloy, Neoloy is the only geocell specifically designed for heavy duty, long-term ground stabilization. Neoloy Geocells have a higher tensile stiffness, creep resistance and more durability than conventional HDPE geocells to last the lifespan of any pavement under heavy cyclical loading. Neoloy confinement is effective in sand stabilization for reinforced bases, while the ‘beam effect‘ mattress is effective in saturated and expansive clay soils, and more reliable than soil cement solutions.
Neoloy Geocells is the best management practice for subgrade improvement for paved roads, highways, railways, embankments and unpaved access, service and haul roads.

About Neoloy Geocell Solution for Clay Soils
Neoloy in a single or double row configuration or in combination with additional geosynthetics, such a geogrids for a “hybrid” solution is an effective ground reinforcement solution for expansive clay soils. One row of Neoloy Geocells (or a geogrid may be used) is placed at the subgrade layer to stabilize the weak clay subgrade. Above this stabilized subgrade, Neoloy is installed in the base or subbase (or ballast / subballast) layer to provide very effective stabilization of the expansive clays, more than soil cement or other chemical stabilizer solutions. The ability to create a semi-rigid slab highly restrains the volume change potential of expansive soils and prevents contraction cracks to reflect up.
