It was decided to construct a road at Kalimantan, Indonesia for better accessibility within the city limits. By having this road at place it will decongest the city main roads. TechFab India Industries Ltd, India has supplied the product required for Ground Improvement in the said project.
In order to construct the road and maintain the level, it was decided to construct the RCC retaining wall on one side of the road with crash barrier at place. But due to geological conditions of Indonesia it was difficult to obtain good frictional soil required for backfilling or else it would have become very expensive project as a whole due to amount of frictional soil requirement. Due to poor soil gradation (more clay content/ fine particles) it was sure that there will be uneven settlement or deformations at road top, hence Ground Improvement was required in order to dissipate the pore water pressure followed by Base Reinforcement.
The design of the walls was carried out using BS-8006 / FHWA-NHI-00-043 guidelines and comprised checks for external, internal and global stability under static and seismic conditions. But due to poor soil conditions it was suggested to use Composite product which performs multiple functions like Separation, Filtration, Drainage & Reinforcement.
By having Separation layer an amount of frictional soil can be reduced drastically, by having Drainage function, pore water pressure can be dissipated immediately and by having Reinforcement Function any uneven settlement or deformations on road top can be avoided.
Hence it was decided to supply TGC 110/ 15 Reinforcing Geotextile for Ground Improvement.
The site had poor soil gradation with high clay content and fine particles, making it unsuitable for backfilling. Without improvement, uneven settlement and deformation at the road surface were inevitable, threatening long‑term stability.
Procuring large quantities of good frictional soil was impractical and costly. The weak soil conditions also risked pore water pressure build‑up, leading to instability in the retaining wall and roadway.
TechFab India supplied TGC Reinforcement Geotextile (TGC 110/15) — a composite product designed to perform multiple functions: separation, filtration, drainage, and reinforcement.
Yes, the retaining wall design followed BS‑8006 and FHWA‑NHI‑00‑043 guidelines, with checks for external, internal, and global stability under both static and seismic conditions.
TechGeo PP Nonwoven Geotextile (TGC 110/15) — engineered for multifunctional performance in challenging soil conditions.
The geotextile solution provided effective ground improvement, reduced settlement risks, and ensured long‑term durability of the retaining wall and roadway, while keeping costs under control.
By delivering a multifunctional geosynthetic solution tailored to Indonesia’s challenging soil conditions, TechFab India demonstrated its ability to provide sustainable, cost‑effective, and high‑performance infrastructure support internationally.
