Types & Spec’s Geomembrane, HDPE Liner, Lake & Pond Liners

Geomembrana HDPE

The smooth HDPE geomembrane is made of high-density polyethylene. It is a blown sheet or low permeability barrier used in order to control the migration of fluids in mining, environmental and agricultural processes. It is a material stabilized with antioxidants, which gives it high resistance to chemicals and significantly improves its durability.

This sheet fully complies with the American standard, a standard that seeks to guarantee the good quality and proper functioning of high-density polyethylene geomembranes.

Main features

  • It is the most widely used geomembrane, as it resists severe physical and chemical conditions and is therefore present in 95% of applications.
  • It has high mechanical resistance.
  • It has high chemical resistance due to its high crystallinity (40 – 60%).
  • Less flexible than LLDPE.
  • Good resistance to ultraviolet (UV) rays.
  • It is a low cost material.

leach pads

Heap leaching is the most important hydrometallurgical method in copper extraction. This geomembrane is used to collect a copper enriched solution or PLS that is generated as a result of this process.

Landfills

The accumulation of solid waste often causes liquid substances harmful to the environment to penetrate the soil. The use of the smooth HDPE geomembrane keeps these substances isolated, waterproofing the soil.

containment ponds

Thanks to the high resistance of this material, in addition to its low permeability, it is very useful to meet the structural requirements of containment lagoons.

treatment lagoons

Also known as pond liner, the chemical resistance and durability of smooth HDPE geomembrane makes it the perfect material for liquid containment.

Mining

In mining processes, geomembranes are commonly used for waterproofing soils.

aquaculture farms

The nature of the processes carried out in the aquaculture industry requires the use of geomembranes to waterproof soils.

Textured HDPE Liner

Textured HDPE geomembrane is made of high-density polyethylene. It is a blown sheet or low permeability barrier used in order to control the migration of fluids in projects with steep slopes or those that require greater friction. It is a material stabilized with antioxidants, which gives it high resistance to chemicals and significantly improves its durability.

This sheet fully complies with the American standard, a standard that seeks to guarantee the good quality and proper functioning of high-density polyethylene geomembranes.

Main features

  • Its outer layer is modified by the application of a gas (nitrogen) or roller used to give the material a textured finish.
  • Increases the friction index (roughness) for application on
  • terrain with steep slopes.
  • Good resistance to ultraviolet (UV) rays.

HDPE Sheet

The nominal smooth HDPE sheet is composed of high-density polyethylene. It is a low permeability blown sheet or barrier ideal for water reservoirs, aquaculture tanks, construction waterproofing, water treatment plants, landfills and ornamental lakes. It is a material stabilized with antioxidants, which gives it high resistance to chemicals and significantly improves its durability.

The nominal smooth HDPE geomembrane differs from the others by its thickness. It is 10% less than the geomembranes and this makes its cost lower, which favors the agricultural sector and low budget projects.

The use of this sheet is recommended only when the project to be carried out does not require compliance with the thickness established in the American standard, a standard that is considered in the quality controls of geomembranes.

Main features

  • It is the most used geomembrane in projects that do not require compliance with the standard.
  • It has high mechanical resistance.
  • It has high chemical resistance due to its high crystallinity (40 – 60%).
  • Less flexible than LLDPE.
  • Good resistance to ultraviolet (UV) rays.
  • It is a low cost material.

Water reservoirs

This geomembrane is ideal for waterproofing drinking water reservoirs and thus preventing the loss of this vital liquid.

Ornamental lake liner

This geomembrane is perfect for this type of project, since it does not require compliance with strict quality control standards.

Aquaculture tanks

Ensuring continuity of operations in this industry depends on avoiding inconveniences in their tanks. With the nominal smooth HDPE liner sheet it is possible to avoid leaks that harm the daily routine.

Construction waterproofing

Preventing leaks in buildings is of vital importance to avoid wear and tear on the structure as a result of humidity. This type of geomembrane is commonly used on roofs, thus preventing rainwater from penetrating the structure.

Water treatment plants

During the drinking water treatment process it is important to avoid leaks, for this reason the use of this sheet is common in these plants.

Landfills

The accumulation of solid waste often causes liquid substances harmful to the environment to penetrate the soil. The use of the nominal smooth HDPE geomembrane keeps these substances isolated by waterproofing the soil.

Geomembrana LLDPE

The smooth LLDPE geomembrane is made of linear low-density polyethylene and is capable of adapting to subsoils with differences in height or hardness. It is a blown sheet or low permeability barrier used in order to control the migration of fluids in mining, environmental and agricultural processes. It is a material stabilized with antioxidants, which gives it high resistance to chemicals and significantly improves its durability.

This sheet fully complies with the American standard, a standard that seeks to guarantee the good quality and proper functioning of linear low-density polyethylene geomembranes.

Main features

  • Greater flexibility than HDPE liner suppliers in Dubai, therefore it adapts without problems to subsoils with differences in height or hardness.
  • Less prone to environmental stress cracking. This geomembrane is more resistant to the usual weakening that occurs as a result of the influence of chemicals or climatic factors.
  • Better elongation properties than HDPE geomembranes.
  • Ease of welding with standard equipment.
  • Less resistance to ultraviolet (UV) rays.

Textured LLDPE Geomembrane

The textured LLDPE geomembrane is composed of linear low-density polyethylene and is capable of adapting to subsoils with differences in height or hardness. It is a blown sheet or low permeability barrier used in order to control the migration of fluids in projects with steep slopes or those that require greater friction. It is a material stabilized with antioxidants, which gives it high resistance to chemicals and significantly improves its durability.

This sheet fully complies with the American standard, a standard that seeks to guarantee the good quality and proper functioning of linear low-density polyethylene geomembranes.

Main features

  • Greater flexibility than HDPE liner 0.75mm, 1mm, 1.5mm, 2mm & 3mm thickness, therefore it adapts without problems to subsoils with differences in height or hardness.
  • Less prone to environmental stress cracking. This geomembrane is more resistant to the usual weakening that occurs as a result of the influence of chemicals or climatic factors.
  • Its outer layer is modified by the application of a gas (nitrogen) or roller used to give the material a textured finish.
  • Increases the friction index (roughness) for application on terrain with steep slopes.
  • Less resistance to ultraviolet (UV) rays.

Non Woven Polypropylene Geotextile

The non-woven geotextile is 100% virgin polypropylene manufactured mechanically in a needle-punching process and supervised under a Quality Management System. The geotextile protects the geomembrane in rocky terrain and also reinforces steeper slopes, improves foundation conditions in walls, allows the passage of water in the subsoil fulfilling the filter function, and improves the bearing capacity of the land by separating the subsoil. – base and subgrade.

Its use is widely recommended in civil construction, although because it is resistant to acids and alkalis, it can also be used in landfills, treatment plants, biodigesters and oxidation ponds.

Main features

  • Greater resistance to degradation compared to polyester.
  • Its ability to filter water provides extraordinary soil containment.
  • Resistant to acids and alkalis.
  • It is more economical compared to other soil stabilization materials.
  • Installation times are shorter.
  • Greater resistance to tension in the manufacture of geocostals.
