FS JSC is one of the leading suppliers in Viet Nam for manufacture, supplying and installing Pre-fabricated Vertical drains (PVDs) and hozirontal drains. FS JSC have joined projects as improving soft soil ground of Bridgestone Tire manufaturing; IHI Infrastructure Asian Co., Ltd; Knauf Vietnam; Western road; 1B highway; Niem II Bridge; Gie Bridge connect to Phap Van Express Way, Ecopark new urban; Cam river new urban,... etc

FS JSC specializes in manufacturing, supplying domestic and imported pre-fabricated vertical and horizontal drains (PVDs, PHDs). In addition, with five modern PVDs installation machines, from Japan or Korea, our company also implement improving the weak soil ground to meet the needs projects from small to large.

I. Design and installation

PVDs installation machines with depth up to 48m, adapted many geological terrains. The capacity of each machine is 10,000 meters per day, so ensuring the productivity of up to 50,000 meters per day. The company has been involved in the improvement weak soil ground by PVDs for the Bridgestone Tire Manufacturing ??40 hectas, IHI factory 20 Ha., and participate in large projects such as Tan Vu bridges, Cat Hai district, Hai Phong, 477 road, Phap Van - Cau Gie Connection Road (Ninh Binh) ....

The company has a team of engineers, technicians and technical workers with many years of experience in the field of constructions as industry, transportation, irrigation and maritime works as well as the field of manufacture and installation. PVDs installation machines are equipped with modern equipment, synchronous, height frame to 40 meters and automatic measurement system. The company has met the requirements of the dometic and oversea projects.

FS Construction JSC. also is a direct importer of PVDs from Korea and Thailand with international quality standards products, which can be delivered within 10-15 days from the date of order.

II. Vertical and Horizontal Drains

Vertical and horizontal drains is a geotextile material used to drain water to increase the consolidation of the ground. The drains is composed of two layers: Filter layer called filter cloth made of non-woven PP or 100% PET geotextile fabric, without any binder and PP drainage, with drainage on both sides.

A. Vertical Drains

1. Improvement of weak soil ground:

PVDs (Prefabricated Vertical Drains), used to treat weak ground, accelerates the consolidation and increases the intensity of weak soil, creating a stable surface for the construction of next items of works. The consolidation of the soil can be accelerated by pre-loading or by vacuum technology.

Stable the ground:

The works can apply PVDs or Horizontal drains to handle a variety of weak soil, including: highway, bridge leading, airport runway, railway, harbour, petroleum depot ... constructions on soft ground with width distribution loads.

Manufacture PVDs

FS Construction Joint Stock Company (FS JSC) is pleased to announce two new PVDs, model VF6, VF7, which is manufactured by us with the special features of the mordern vertical drains, which meet the rigorous standards in national and international.

2. Horizontal drains

* Composition of horizontal drains.

- Horizontal are shaped the same ordinary vertical drains but larger in size

- Horizontal drains have common types of cross section as follows: 8.0mm x 150mmm; 8.0 mm x 200 mm; 8.0mm x 300mm; 8.0mm x 600mm

- Structure of horizontal drains including 2 main parts:

The Core: Structured into drains, usually made of polyvinyl chloride (PVC) or polyolefin;

Filter cloths: Used to drain water from the ground through the core drainage, usually made of Polyester (non-woven).

* Characteristics of horizontal drains

Pore water is absorbed through the filter cloth and drained into the heart of the drains. Due to this characteristic, even when the horizontal drains is expanded, the drainage capacity is maintained.

- This is a material with high tensile strength and elongation while fixed free movement of the core and filter cloth so that it can deform according to the change of terrain due to subsidence.

- The drainage is not only lightweight and easy to transport but also does not require any special bonding material!

* Application range:

- Type of soil: Apply to fine sandy soils, clay

- Load: Load capacity is over 250kN/ m2 equivalent to the height of 14 meters

* Application:

- Embankment: Replacement for sand bed and filter sand

- Sports area, golf course, sports grounds

- Other applications replace embankment blocks and prevent seepage
