Steep slopes/retaining walls

Reinforced soil solutions are very well suited for use in highway grade separation and embankments. With the use of reinforced soil solutions as compared to conventional walls, embankments can be constructed:

  • Faster
  • Requiring less land footprint
  • Saving more than 20% of project costs

Furthermore, reinforced soil technology offers various fascia options which include vertical walls with precast concrete blocks / panels and steep slopes with green or stone fascia.

 

Embankment slope protection/erosion control

Conventionally, stone pitching has been the preferred solution to reduce erosion. The availability of stones is posing a great challenge from an environmental and commercial standpoint.

Helps to prevent erosion by effectively confining the topsoil within its three-dimensional frame. Locally available fertile soil can be used as an infill which can be further vegetated to provide a green finish, thus avoiding the use of expensive stones for slope protection. Installation is extremely simple and five times faster as compared to stone pitching.

 

Pavements

Reinforcement solutions help in distributing the loads over a larger surface area and helps eliminate rutting and problems arising due to expansive soils. Help in economizing the pavement sections by reducing the requirement of expensive quarried materials in the base and sub-base layers while providing a longevity.

Access roads

Ground improvement solutions help in strengthening the subgrade of access roads / unpaved roads, reduce differential settlements, are easy and rapid to construct, can be engineered for site-specific challenges and can make use of site won materials.

 

Embankment & ground improvement

Solutions are well-established to reduce the bearing pressures exerted by embankments on poor subgrades by spreading the loads uniformly over a wider area. This is a more economical option as compared to conventional solutions and presents a viable alternative in cases where intermediate improvement is required.

Drain lining

Our cutting-edge geocell lining solution for chute drains and canals along highways. It is a tough, flexible, lightweight, perforated polymeric confinement system which is transported in its collapsed form, then unfolded/expanded onsite to form a honeycomb structure which is then laid out precisely and packed with evenly distributed aggregate material, making it a surprisingly efficient and economical alternative to the usual cumbersome methods.
