Basins for water storage and ponds


DL Plastics B.V. has been known for many years as a supplier and manufacturer of high quality plastic materials and finished products.

In our private factory our certified professionals use the latest welding equipment and we are yearly producing thousands of liners for waterproofing of tanks or silos for water storage and also hundreds of waterproofing membranes for water lagoons. These high quality products are traded in the Netherlands and also exported to all parts of the world.

At this moment there are a view standard materials used for these application like; flexible PVC, FPP and LDPE lining. Most famous problems by using these standard materials are leakage caused by recirculation water or influence of UV light (Sun) or damage due to wind.

After years of research there is developed a new flexible Liner which viewed on the test results is better suited for these applications. The test results show us that this extremely high quality material is better resistance against influence of UV (Sun) light and more resistant to high mechanical stress and more resistant against damage due to wind.

We introduce the revolutionary DELAFLEX® Lining with 15 years warranty

DELAFLEX® Liners custom made for all types and brands of tanks or silos.

DELAFLEX® waterproofing membranes for lagoons on mega large dimensions.

DELAFLEX® Lining is available in 0.6 mm and 1.0 mm thickness and DELAFLEX® is welded by DL Plastics B.V. in accordance with guidelines of the KIWA BRL-K 537.

PVC Foil is often used for waterproofing ponds and water basins. PVC foil is available in thickness of 0.5 mm up to and inclusive of 1.5 mm. We have a very large and modern factory where very large covers are made of 10.000 m² or larger.

The expected lifespan of the PVC pond liner with a thickness of 0.5 mm is about 6 to 10 years and for PVC pond liner with a thickness of 1 mm it is about 10 to 20 years. The lifespan can be extended by shielding the liner as much as possible against U.V. rays.

DL PLASTICS B.V. also supplies and delivers EPDM foil, which is a rubber foil that does not contain plasticizers. This quality is increasingly used in ponds, because it is highly resistant to ozone and U.V. radiation. Moreover, it is a permanent elastic material and therefore very easy to handle on site because of its suppleness and flexibility. It has a lifespan of no less than 30 years. It needs little maintenance and repairs are easy to execute. It has no resistance to gasoline, toluene, turpentine, oil etc. Furthermore, it is relatively heavy. A thickness of 1 mm is mainly used. We can supply virtually any size prefab in its entirety. It is also possible for our engineers to install the foil. If necessary we can provide: tape, kit, primer etc.

We also supply and fix the complete steel tank, silo, liner, anti-algae cover and floating cover or steel roof at your location.

On request we will send you our complete price list without any obligation.
