HDRPE is used for ponds, lakes, golf courses, mining operations, retention ponds, fish farms, green landscapes, reservoirs, tanks, pools, environmental fills, concrete foundations, tarps, infrastructure and thousands of other uses.

It is a high-density waterproofing polyethylene geomembrane , which is manufactured under strict quality controls. Its construction is based on virgin resins that do not contain additives or fillers that can evaporate and cause deterioration as time progresses. This geomembrane, better known by its acronym in English as HDPE, is the most used material for lining in solid waste deposits in mines. In addition, others that have to do with the containment of liquids. Definitely if we should recommend where to apply it, it would be in projects with low permeability, resistance against ultraviolet rays, and exceptionally high chemicals.

Advantage

The HDPE geomembrane is of great thermal and chemical resistance. It stands out because it is not attacked by acids, it resists water at 100 ° C, flexible at low temperatures since it is made of high-density, high-molecular-weight polyethylene.
Features
The main functions of the HDPE geomembrane are waterproofing, protection and separation. For this reason, it is considered one of the most effective waterproofing systems, which combines low initial cost, high resistance and durability. Also, do not forget that for it to work well, you have to know how to choose those with adequate thicknesses, according to your application. Remember that the installation process is rigorous but that it allows a good lifetime of the HDPE geomembrane.

Applications

This type of geomembrane is often used too much in:
:: The waterproofing of landfills and leachate ponds.
:: In the waterproofing of platforms and slopes of roads, railways, etc.
:: For coatings in water conduction channels for irrigation.
:: In hydraulic and mining projects.
:: In the Oxidation lagoons.
:: Biodigestores.
:: Tanks of Molasses.
:: Hydrocarbon storage tanks.
:: Artificial lakes.
:: Landfills.
:: Coating.
:: Hoyas of rainwater catchment, and among other works.

With the massive fall of leaves and species beginning to dry up, the spaces housing water and plants in the garden now require certain tasks to see them splendorous again in spring.

When autumn arrives, the main care for the health of the pond and the aquatic plants that inhabit it is to avoid the incorporation of large amounts of organic matter, either by the fall of leaves characteristic of this time, or by the species palustres, floating and rooted that dry up with the first frosts.
The decomposition of all this material in the water body generates a double problem. On the one hand, the gases caused by fermentation, dissolved in water, can affect fish; on the other hand, the nutrients caused in this process serve as food for algae, especially at the beginning of spring, when they proliferate.

To avoid these problems, the most effective option is to cover the water with a net that prevents the entry of leaves or, if possible, with a transparent nylon. This not only serves the same function, but also acts as a greenhouse, prolonging the growth and flowering of some species, allowing us to continue enjoying the pond. If it is not possible to cover it, remove the leaves on the surface with a flake or net and clean the mulch that accumulates on the bottom.

Also at this time it is necessary to prune all the dry or burnt material by the cold, especially that of the palustres and floating, which is the most voluminous.

Solutions start at the very moment we plan the construction of the pond, looking for places that are away from deciduous trees. This will not only prevent a massive fall of leaves in the water, but also the possible breakage of the pond by the action of the roots.

Another topic to keep in mind about the care of ponds in autumn is to know which wind predominates in the area and which is its main direction. In this way, it is avoided to drag the fallen material towards the pond. One solution is to place high marsh species as a barrier.

Pond liners

are made of impermeable materials designed to retain water. We recommend buying the correct type and thickness of pond liner to meet demands of pond size and reduce maintenance issues over its lifetime. Here are a few common mistakes to avoid when buying and installing your  liner: • Guided by price alone:  We recommend you choose a membrane that is thick enough to resistant puncturing, one that is not likely to deteriorate when exposed to the sunlight and that is strong enough to line a pond for many years. It is worth spending a little more upfront to avoid problems later. Plastic or PVC liners are not as durable as rubber liners such as Butyl or Epalyn. The best choice for a garden pond would be a 30 mill thick HDRPE liner.

Ordering the incorrect size pond liner: Once you have dug the hole, measure it accurately in three directions – the length, breadth and depth. Then go online to put these figures into a pond liner size calculator to get the exact dimensions. Remember to factor in extra for the lip to anchor the liner over the edge of your pond – at least 2 feet/0.15m overlap to go around the entire rim of your pond.

Failure to secure the edges of the liner: When installing the liner, generously overlap the edges to make sure your feature is water tight. If the overlap is insufficient, the sides of the pond will become exposed as you start to fill your pond with water. The overlap must then be secured in place with your choice of edging material.

Avoid these mistakes to ensure you create your dream garden pond that will give you years of pleasure.

The geomembrane for symbiotic aquaculture is one of the most important elements in the beginning of aquaculture projects. The beginning entails the purchase of material machinery necessary for the aquaculture farm, fish farm or shrimp farm. In a large number of occasions, the necessary information is not available to choose the appropriate aquaculture instruments or materials. Our trajectory as project developers and consultants has given us the opportunity to identify the shortcomings that producers have at the beginning of the projects. Thus, 85% of investors and producers are lacking in information on the characteristics of the machinery and materials.

What is a geomembrane or liner for symbiotic aquaculture?

A geomembrane or liner is a waterproof sheet composed of plastic resins and chemical additives that give it certain qualities. Usually the most used additives are carbon, antioxidants and thermal stabilizers. These substances give the geomembrane mechanical resistance, against ultraviolet rays and against heat.

There are many types of geomembranes depending on the polymer they are made of. For example: PVC (Polyvinyl chloride). PP (Polypropylene). PS (Polystyrene). PET (Polyethylene terephthalate). LDPE (Low Density Reinforce Polyethylene) or HDRPE (High Density Polyethylene). Some of these polymers are used to manufacture bottles. Others for plastic packaging, others for pipes and so on. Of all of them, the geomembranes or liners most used in symbiotic aquaculture are those made with HDRPE or LDPE.

Differences between geomembranes for
HDRPE and LDPE symbiotic aquaculture

HDRPE (High Density Reinforce Polyethylene) is a thermoplastic polymer of ethylene, polymerized by free radicals. Like LDPE (Low Density Polyethylene). The latter has three or four carbon atoms. It is also confused with various branches at the molecular level. This makes them have a low density and that increase their flexibility at the cost of their resistance. The HDPL has almost no ramifications. So it has a more compact structure that increases its rigidity at the cost of flexibility. In this way, HDRPE is more resistant to mechanical stress, tensile breakage or impacts than LDPE. However, this one is more flexible. Usually, for symbiotic aquaculture, the HDRPE geomembrane or liner is more used due to its greater resistance.
