Wall and slope reinforcement

Over the years, there are quite a number of engineers who has come out effective solutions for the reinforcement of slopes and walls using geogrids and composite geotextiles.

Modular block wall

Apart from using the geosynthetics as solution, we also provide “design and build” services for modular block wall. The modular block wall is an alternative where there is a limitation of space for reinforcement or the deign called for more symmetrical façade.

Sludge Dewatering

Sludge dewatering splits sludge into liquid and solid mechanisms for waste minimization. There are various technologies for sludge dewatering, including the conventional ways, or by using geotubes.
It is vital to take note that dewatering is not proposed to treat the sludge or liquid, it only separates the solid and liquid components so that it is easier and more cost-effective to handle the separate phases for ending disposal. The sludge once dewatered, both solid and liquid components may contain contaminates that will need to be treated separately.

HDPE Geomembrane

A geomembrane is a synthetic membrane liner with very low permeability used to prevent fluid or gas migration. In geotechnical works, HDPE geomembranes are commonly used as liners for sanitary landfills, mining and leachate ponds, man-make lake/ponds, waste water and chemical treatment plants, agriculture ponds and etc.

Prefabricated Vertical Drain

Prefabricated vertical drain is a prefabricated material consisting of a plastic core covered by synthetic geotextile filter jacket which allows water to pass into the core while restricting instruction of soil particles. Soil improvement technique using PVD is one of the most cost-effective method to remove excess pore water from the soil. By inserting PVD vertically into the soil, the pore water will flow laterally to the nearest drain and travel upright to drain out of the soil. PVD can easily be installed at closespacing, thus shortening the path of the pore water from a low permeable soil layer to free water surface or to pre-installed drainage layer and expediting the consolidation settlement process in saturated soils.

Data Logger

The maximum pressure during penetration, verticality and the grid and reference of the installed PVD will also be recorded. 

Geotextile

Geotextiles are permeable fabrics, usually made from polypropylene, polyester, polyethylene and polyamides. Geotextile fabrics come in three basic forms: non- woven geotextiles, woven geotextiles, or heat bonded geotextiles. They currently support many civil engineering applications including roads, airfields, embankments, canals, dams and railways. For these applications, geotextiles are installed to increase soil stability, provide erosion control, reinforce the structure and ensuring stability.

In road and airfield pavements, geotextile is placed on top of soft sub-grades prior to placement of the granular sub-base layer. As a separation layer, geotextiles can aid preventing the intermixing of dissimilar materials and reduce the overall thickness of the road section by requiring less aggregate during construction. The use of geosynthetics thus extends the maintenance-free life of pavements constructed on soft compressible soil.

Geotube Technology

Geotube is a geosynthetics container which fabricated from high strength permeable geotextiles with uniquely designed retention properties. It is usually used to prevent the erosion of foundation soil through the granular layers in the breakwater and also control the erosion problem by the beach due to the force of the wave. Installation of the container helps to protect the shoreline by adding a barrier between the edge of the shore and the water. In addition, the accumulation of sand is naturally helping shorelines retain their nature sand output which able to manage destructive wave action and beach erosion.

Sandfill Mattress

Sand filled mattress is a flat mattress made up from two layers of fabrics sewn together to form the cellular tubes when fill with sand. Application of sand filled mattress is a low budget and effective method to prevent slope and river bank erosion by forming a layer of vegetation on top of the surface. It is also used in protection of seabed, waterways, mining areas and so on due to its ecofriendly characteristics. This technology requires less installation and maintenance cost thus lower the expenditure.

Geogrid

Geogrids are geosynthetic material that commonly made of polymers such as polyester, polypropylene or polyethylene. All the geogrids have the ribs and apertures. The apertures are the openings that allow for the soil strike through from one side of geogrid to the other. They are used to reinforce retaining walls, as well as subsoils below roads or structures because installation of geogrid will help to prevent soil and wall movement due to their high ability to distribute the load across large area. The geogrid system is more flexible in nature and has great adapting ability with the deformation of the foundation. They are also cost saving material therefore having high demand in consLruction projects.
