3. WIILOCK | E-LOCK Concrete Insert HDPE Profile

Securing HDPE geomembrane liner to concrete structures can be carried out either by mechanical fastening (using stainless steel flat bar, neoprene sponge and anchor bolts) method OR by embedding WILLOCK into concrete and HDPE geomembrane liner is then welded onto the exposed surface of WILLOCK using extrusion welding method.

Wil-Key International produces WILLOCK in different shapes and custom length to suit the actual project requirement.

All WILLOCK are made from virgin HDPE resin with 2 to 3% carbon black content. WILLOCK are made from the grade of resin normally used by major manufacturers to make HDPE geomembrane liner.

The advantages of using WILLOCK against mechanical fastening are cheaper in cost, easier to install and more secured.

5. Geosynthetic Clay Liner (GCL) 

Geosynthetic Clay Liner (GCL) is an internally reinforced 3-layer polypropylene composite with premium grade sodium bentonite to provide high shear strength and consistent low hydraulic conductivity, a critical performance criteria for GCL's as an effective barrier against liquid migration and gases. This is achieved with premium quality sodium bentonite, using clean water for its hydration and maintaining the GCL in a confined state during the hydration process.



  • Offers better moisture absorbency and does not leach out easily during installation.
  • Mass per unit area of sodium bentonite is evenly distributed and retained for a uniformed low hydraulic conductivity. 
  • Superior tensile strength and internal shear resistance with long term chemical biological resistance.
  • Prevents stretching and contracting during shipment and installation to ensure continuity and uniformity of the bentonite layer throughout the GCL.
  • Structurally stable when installed on slopes and suitable for applications in a hydraulic environment.

6. Gabions | Gabion Cage | Gabion Mattress

Gabions are cages which are engineered from double twisted hexagonal woven steel wire mesh. Delivered flat-packed, our gabions are assembled and then filled with stones at the project site.

There are numerous uses for these modular units and are typically used to form flexible, permeable and monolithic structures such as retaining walls, channel linings, hydraulic control structures and erosion protection. They are increasingly being used in architectural applications as well.

We are a gabion specialist where plastic, PVC-coated, galvanized iron, steel wire mesh, manufacturing can be make-to-purpose, we are able to service for several industries regardless of construction or industrial usage. Our Gabion basket are available in a variety of different sizes. It comes in 0.5m and 1m height and 1m, 1.5m, 2m, 3m or 4m long. The size of stone used for our Gabion basket infill varies from 110mm to 250mm.

7. HDPE Geomembrane Lining | Pond Liner

HDPE (high-density polyethylene) is the most chemically resistant member of the polyethylene family on account of its dense configuration (>0.94 g/cm3).High-Density Polypropylene or HDPE Geomembrane is a geosynthetic erosion control product largely used in liquid containment areas. Nowadays, it is the most commonly used membrane for containment structures in various applications. It offers great ultraviolet protection and ageing resistance from the intense stresses of weather.

HDPE (High-density PolyEthylene), or HDPE Geomembrane is largely used at lquid containment area, acting as a liner to prevent seepage loss and contaminants from entering earth ground. The applications of HDPE Geomembrane solves the issue of water seeping in or out from the earth ground such as agricultural ponds, aquaculture ponds, golf courses, canals, water tanks, oil tank, water tank, concrete tank, sanitary landfill cell, waste water pond and other critical containment applications. HDPE Lining for water tank is used to form a protective barrier for internal of pressed steel water tank. HDPE Lining for water tank is a proven method that ensures total sealing efficiency and protection for water tank from leakage, cracking and erosion. A thick, durable, HDPE Lining can be placed in exposed applications where the cost of other materials may be prohibitive.


  • Provide positive water containment
  • Help improve and sustain water quality
  • Establish soil erosion control
  • Low maintenance cost
  • Reduce disease risk
  • Manage waste containment
  • Ease harvesting
  • Increase turn-around time between crops.

10. Geogrid Wall System  

Geogrid is a geosynthetic material, made of polymers, which is used to reinforce soil behind retaining walls. Installed in horizontal layers between wall courses and extending into the soil behind a wall, geogrid stabilizes the soil and so increases a wall system's mass and stability.

A geogrid is geosynthetic material used to reinforce soils and similar materials. Soils pull apart under tension. Compared to soil, geogrids are strong in tension. This fact allows them to transfer forces to a larger area of soil than would otherwise be the case.


  • They reduce the depth of excavation required on unsuitable subgrades.
  • Geogrids also provide enhanced safety and greater seismic durability by stabilizing slopes and increasing soil strength.
  • By reducing the differential settlement of roadways, geogrids reduce the need for maintenance and extend the life of paved roads.

11. HDPE Pipe Butt-Fusion Welding Machine  

Normally, HDPE pipe is supplied in bars of 6.0m or 12.0m. To connect the pipes together or connect the pipes & fittings, HDPE pipe welding machine is a necessary tools.

HDPE pipe welding machine, also called HDPE pipe fusion machine, HDPE polypipe butt fusion machine or HDPE pipe welding equipment, is a kind of heat-fusion machine, which is designed for HDPE pipe. By fusion the surface of pipe ends (or fittings ends) to make the molecular structure
recombined, so the HDPE pipes (or HDPE pipe fittings) connected together.

12. HDPE Pipe Electrofusion Welding Machine  

HDPE Electrofusion is a method of joining PE, HDPE and other plastic pipes using special fittings that have built-in electric heating elements which are used to weld the joint together.

The pipes to be joined are cleaned, inserted into the electrofusion fitting (with a temporary clamp if required) and a voltage, normally 40V is applied for a fixed time depending on the type, and size of the fitting in use. The built in heater coils then melt the inside of the fitting and the outside of the pipe wall, which weld together to form a very strong homogeneous joint. The assembly is then left to cool for a specified time. Then it's done.

In the electro fusion process a heating wire permanently mouled into the fitting gets heated by current at a low voltage. The surrounding material around the wire gets melted and expands due to the warming. The melt starts closing the gap between pipe and fitting, leading to a heat transition to the pipe which also gets heated and melts in the welding zone. The pipe material also expands.

The increasing material expansion between pipe and fitting, which is hindered by the cold zones outside the welding zone, leads to a build up a welding pressure between pipe and fitting and a homogeneous welding connection emerges.
