Geomembranes are the great strangers that hide behind the success of large public works and industrial buildings. In previous posts we already told you about the application of these geosynthetics in different industries but today we want to be more concrete talking about the use of geomembranes in natural pools and ponds.

The construction of a pond or a natural pool, entails a complexity that may not be seen with the naked eye. After the earthworks and the refining of the land, a waterproofing process must be carried out so that no leaks occur. In this last step of the procedure is where geomembranes and geotextiles come into play.

The use of geomembranes in this type of construction is easy, economical and functional. The advantages of covering the dug ground with sheets of high density polyethylene or PVC are innumerable. Both in the case of natural pools and in ponds, this waterproof coating prevents the spread of compounds that alter the water, that is, the water remains isolated from all types of fertilizers, agrochemicals or land preventing contamination or contamination. embarre. In this way, we make it possible to be a water suitable for people bathing and to house banks of fish or natural plants.

The advantages of using HDPE geomembrane to build a pond or pool:

1.HDPE geomembrane is a kind of soft material with good waterproof performance and high anti-seepage coefficient. HDPE geomembrane has good frost resistance and high temperature resistance, high temperature can reach 110 degrees, low temperature can reach – 70 degrees.

2.It has stable chemical properties and can resist strong acid and alkali salts and corrosive materials. It can meet the needs of high standard construction projects, has good aging resistance and strong tension resistance.

3.Long time exposure to harsh environment will also maintain the original performance, can adapt to various weather conditions.

4.It has strong tensile strength and recoverability, adapts to different geological changes, and has strong ability of strain.

5.There is no preservative in the molecule, because of this advantage, it is widely used in food, making a fresh-keeping film or bag.

This kind of plastic membrane completely replaces the original PVC material and reduces the environmental pollution.

We also prevent the occurrence of damage that may suffer other types of waterproofing due to the passage of time or earthworks and that ruin the time and money invested both in the construction and maintenance of the pond. To avoid damage to the geomembranes, the use of a protective geotextile is used as a constructive solution, that is, the geotextile will protect the geomembrane from possible punctures that compromise the tightness of the area. It is very important that this geotextile has the best resistance characteristics and that it is of high tenacity. For this, the recommended is a geotextile that is 100% virgin polypropylene discarding the use of recycled or regenerated fibers that retain mechanical properties.

The geomembranes have a very high resistance against cracking or deterioration due to the effect of temperature due to the solar incidence, a factor that makes them the ideal material for this type of installations since this prevents the dreaded leaks or losses of Water. In addition, we are facing a material whose installation procedure is fast and that has a useful life of more than 30 years.

Thanks to its adaptation, strength and low level of permeability, geomembranes have made their way into many types of civil and industrial construction. After having a great tour in the construction of irrigation canals, mining, waterproofing tunnels and reservoirs and a long etcetera, now we can also enjoy its great qualities while we stick a bath in a natural pool or contemplate the beauty of a pond .
