Overview

Building embankments over soft, weak soils is one of the most demanding challenges in geotechnical engineering—where low shear strength and high compressibility can lead to excessive settlement, instability, or even shear failure. APEC’s GRIDTEXTILE® geocomposite provides high-strength base reinforcement—enhancing stability, increasing bearing capacity, and enabling safe, cost-effective construction with faster installation and long-term performance.

Problems We Help Solve

Engineers and contractors commonly face the following challenges when constructing embankments on soft subgrades including:

Low Shear Strength and Poor Load-Bearing Capacity

Weak foundation soils often lack the shear strength required to support heavy embankment loads.

Basal reinforcement systems distribute loads more evenly, enhancing soil stability and preventing shear failure.

Excessive and Uneven Settlement

Soft or compressible soils cause differential settlement, leading to structural distortion or cracking.

Geosynthetic reinforcement layers minimize vertical deformation and ensure uniform settlement performance.

Risk of Foundation Failure or Lateral Spreading

Instability at the base of embankments can lead to lateral movement or rotational failure.

High-tensile geogrids and composite systems provide basal restraint, improving overall slope and foundation stability.

Construction Delays and Cost Overruns Due to Soil Instability

Unstable ground conditions often require time-consuming soil replacement or improvement techniques.

Reinforcement solutions enable faster, safer construction without extensive ground treatment, reducing project delays and costs.

Limited Options for Building on Wet or Saturated Ground

Wet, weak, or marshy soils restrict conventional construction and increase settlement risks.

Basal geosynthetics enhance load distribution and create a stable working platform even on saturated subgrades.

Insufficient Space for Extended Side Slopes on an Embankment

When space is limited, embankment design may not allow gentle side slopes for stability.

Basal reinforcement strengthens the foundation, enabling steeper slopes and optimizing available land area.

Our Solutions

GRIDTEXTILE® is a high-strength geogrid composite engineered for basal reinforcement over soft subgrades. Placed at the foundation level, it delivers superior tensile strength and confinement, increasing the embankment’s resistance to shear failure in both the fill material and the underlying weak soil.
