Why is plastic waterproof membrane better than natural materials

Some ecological ponds or breeding ponds are built to simulate the natural environment as a selling point, allowing high-value fish or plants to grow rapidly. Pool substrates that mimic natural environments choose natural materials rather than plastics, mostly clay or bentonite, which are often advertised as being good for water quality. But in fact there are also many problems, so I think this is not a very ideal choice. In the case of pools for wastewater treatment or chemicals, natural materials should never be used as linings. In most cases, plastic membrane are definitely safer than natural materials.

Penetration

Technically, the plastic waterproof membrane provides the owner with the highest level of impermeability, and after various leakages occur, it can be repaired more efficiently to prevent the loss of water. Clay-based materials do not provide complete waterproofing, and as the material ages, it can cause more leaks. Plastic waterproof membranes, such as PVC, OBC, and TPO, can provide decades of protection, prevent water loss, and prevent the owner's money from declining.

Durability

Over time, natural materials may bond to the bottom soil, so regular top-ups in less than 5 years are required. If designed and installed properly, plastic waterproof membranes can last for decades, and the long-term maintenance costs are lower than natural materials, because natural materials have to be re-drained, filled, and reinforced, which is relatively troublesome.

Leakage

Pure clay liners often suffer from multiple leaks, even after the first build, most of which occur gradually over a 5-year period. It is completely impossible to repair these leaks perfectly, uneven repair may cause soil instability, and it is very difficult to evenly lay them. Possibly re-draining and then carrying a large amount of material to refill, which is time-consuming and expensive.

Easy to clean

There is no obvious separation of the natural substrate pool from the original soil layer, because it must be mixed with the original bottom and reinforced to prevent water loss. However, if the cleaning action is to be performed, it is easy to scrape off the natural substrate material, and also cause some damage and leakage. The plastic waterproof membrane substrate is more durable, and it is also very fast when cleaning is necessary. .

Stability

Due to cost and installation considerations, natural material pads are usually not covered in a thick layer. When there is no water, it will cause separation from the soil, which means that it is more susceptible to external environmental influences and causes loss and damage. A good pool liner needs to deal with a variety of adverse factors to prevent moisture and soil loss.

According to different engineering needs, of course, the plastic waterproof membrane can also be covered with soil, stone, etc. to create a natural environment simulation of the pool and reduce the risk of leakage. Make more use of plastic waterproof membranes, and do not use natural material completely, so as not to cause more trouble.
