Highways

Strata 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:

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.

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

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.

StrataWeb® 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.

Pavement reinforcement improves structural performance by using geogrids or geocells within pavement layers or at the interface with the subgrade to support the pavement structure under load. To understand why reinforcement is used, it is important to consider how pavements behave over time.

Strata 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. StrataGrid™ HyTen range is highly effective for use in embankments over piles as a load transfer platform (LTP).

Drainage management collects, carries, and discharges surface and subsurface water so pavements, embankments, and side slopes stay stable over the design life. Without proper drainage, water enters base and subgrade layers, softens the soil, and leads to rutting, cracking, and edge failure.
