There is a requirement for large quantities of water in farming areas where water is not naturally available at the level required. To alleviate this concern, canals have been structured to ship water from the source to where it is required. Earthen canals, even though comparatively low-cost to build, loss 50 percent or more of the water they carry to seepage and the concrete veneer may still break over the time. Singhal Industries is known to be the best Geomembrane sheet suppliers.

More in recent times, stretchy lining fabrics such as LDPE and HDPE have been gaining attractiveness as the most profitable lining solution for a numerous applications, containing irrigation and potable water. LDPE / HDPE Liners, either alone or in combination with a concrete veneer, can greatly enhance the efficiency of a canal lining procedure. Not only are corrosion and vegetative interference mitigated, but also leakage is greatly decreased as compared to earthen or concrete alone process. While the concrete facing may still break over time, the geomembrane remains in its position under the veneer to avoid seepage until the concrete can be mended.

The demand for water keeps on gathering, particularly for irrigation in most of the farming regions. To decrease this problem, Liners for Canal Lining have been structured so far to carry water where it is required, as the natural water is not enough for farming. 

The Canal Lining is a resistant coating that is proposed for the bed and sides of the canal. Geomembrane has been utilized as a water canal liner to control leak and is a choice to more conventional lining methods such as concrete and compacted soil. 

HDPE geomembrane sheets for Canal Lining are a feasible option to concrete and compacted earth for lining canals and dams to decrease seepage. In adding, leakage is significantly abridged as compared to soil or concrete standalone procedures. 

While RCC concrete coatings can still break down over time, the geomembrane remains under the veneer to avoid seepage until the concrete is needed. The cracking or any damage to canal liners has to be taken care of. Else, canal liners can be sheltered with a coating of backfill or by placing the liner under a conservative concrete channel.


How to Use Liner for Canal Lining

  • A HDPE geomembrane sheet can be fitted for canal bed and sides. 
  • HDPE geomembrane sheets can also be utilized as a convenient procedure for repair of existing stained surfaces of concrete facing the canal. 


Advantages of HDPE Geomembrane Sheet as Canal Liner

There are multiple benefits of liner for canal lining and Liner for Dam Lining is it avoids water logging, which effects in growing the groundwater level.

  • Trickle loss lessening to maximum spread: The Liner for Canal Lining is useful as it is absorbent in nature, resultant in the deterrence of water loss because of seepage.
  • Rising of Groundwater Level: Another advantage of Geomembrane liner for canal lining is it stops water choking, which results in enhancing the groundwater level.
  • Decrease in Maintenance Expenses: The smooth surface supports a higher flow rate, which means it decreases the measurement to move an equivalent amount of water, resultant in lower maintenance expenses.
  • Surge in channel capacity and hydraulic competence: The Liner for Canal Lining, avoids the loss of water by mechanically outcome in growing the capacity and hydraulic competence. 
  • Comfortable to handle, extent, and transport: It is a simple procedure of scattering the liners for canal lining. The team of professionals put the liner down to the lowest of the pond and up the other portion.
  • Safety from floods: An unlined canal founded on a weaker foundation is always in risk and a breach may happen. However, the help of sturdy concrete lining eradicates all such dangers and safeguards from the flood.
  • Protection to chemical action and quick formation: The Liner for Canal Lining, such as HDPE geomembranes, is largely resilient to chemical action, which makes it flawless for the lining of canals that convey chemically-laden water. Separately from that, it is quick to fit, which decreases the expense of labor and time of structure.
  • Safety against corrosion of channel corners and bedding: Liner for Canal Lining benefits to avoid corrosion from the corner and the bedding of the canal by proposing a stable and steady surface which results in the decrease of the threat of structural damage and keeps the canal’s operational competence over time.


Characteristics of HDPE Geomembrane Sheets:

  • Surface and Finish Options: The HDPE geomembrane liner is functional in both textured and smooth finishes, delivering flexibility to various usage situations.
  • Temperature Conductivity: Unusually conductive in high-temperature differences, making it appropriate for applications needing thermal constancy.
  • Chemical Confrontation: Holds outstanding resistance to a broad range of chemicals, increasing its usability in stimulating industrial and environmental atmosphere.
  • UV Safety: Proposes a trustworthy ultraviolet safety shield, making it appropriate for outdoor applications where disclosure to sunlight is predominant.
  • Weather Resilience: The HDPE geomembrane sheet displays excellent age conflict against the intense pressure of weather, keeping its reliability over time.
  • Welding and Molding: Created for easy welding and molding, enabling suitable fitting and customization according to project needs.
  • UV Stabilization: Created by utilizing UV stabilizers, this increases its weather resistance capacity and overall permanency.
  • Puncture and Water Conflict: Establishes high puncture conflict, making it proficient at enduring mechanical stress, and displays exceptional water conflict.
  • Stretchy Strength: Boasts increased tensile strength, contributing to its sturdiness and capability to survive different mechanical forces.
  • Permanence: Designed for longstanding usage, the geomembrane liner proposes lengthy service life standards, reducing the requirements for frequent substitutes.
  • Roll Format: Delivered in broad rolls for effective handling and application, functional with single or double-sided textured surfaces.


Considerations When Choosing Geomembrane Sheet Suppliers

  1. Depth and Strength: Various applications need geomembrane sheets with different thickness and strength. Singhal Industries leading Geomembrane sheet manufacturers in India provides a range of choices, enabling engineers to select sheets that fulfill the specific needs of their assignments.
  2. Installation Situations: The installation situation, containing site characteristics and climate, play an important role in the performance of geomembrane sheets. Singhal Industries provides assistance on choosing the appropriate geomembrane depends on the unique conditions of each assignment.
  3. Environmental Effect: Singhal Industries geomembrane sheet suppliers prioritize environmental accountability and propose geomembrane sheets that support sustainability goals. Selecting items with minimal environmental impact is required for responsible engineering practices.


Frequently Asked Questions (FAQs)

What is the use of geomembrane?
Geomembranes are enormous resistant membranes manufactured of (un)reinforced polymeric materials and utilized to stabilize earth and to protect landfills assuring containment of hazardous or municipal wastes and their leachates.

What is geomembrane used for in civil engineering?
A geomembrane is usually utilized for the suppression of dangerous fluids that can pollute the ground or nearby structures if not correctly controlled. Geomembrane can frequently mean that the chemical resistant features of the liner will be heavily relied on.

How thick is a geomembrane sheet?
The density of the HDPE geomembrane utilized in anti-seepage and waterproof tasks varies from 0.5mm to 3.0mm. The density can be 0.75mm, 1.0mm, 1.25mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, etc. Utilize hot-melt welding tools for joint processing.
