Vegetables and fruit sector: waterstorage.
Our high quality waterstorage silos are ideally suited for the storage of rainwater, drinkingwater or water for irrigation in horticulture.
The main components of a water storage silo/tank are the 450mu galvanized S350 steel panels, bolts, washers and nuts.
To make the watersilo waterproof we use a plastic liner on the basis of the liquids to be stored, we determine the quality plastic which may be PVC ore EPDM, but in most situations, we advice DelafleX.
The waterstorage silos and tanks of are available in various diameters 1,86m up to 40m and heights 0,83m up to 6,10m with a capacity up to 4,000,000 liters.
On base of the silo/tank diameter and the height a calculation will be made to determine the thickness of the steel panels.
To reduce the weight of the steel panels
to the minimum and to obtain the maximum strength, with a special engineered machine the flat galvanized or zinc coated steel plates will be corrugated and equipped with the holes for mounting the bolts. For the guaranty and to create of the waterproof storage tank a tankliner must be installed.
Water storage silos are guaranteed:
- Very conveniently priced.
- High quality materials.
- Fast delivery.
- Easy to transport.
- No heavy Foundation needed.
- Easy to move and remove.
- To install on almost every flat surface.
- Easy to assemble and install manually.

In accordance with the client's wishes transit pipes and or seeling rings of varying diameters can be fitted into the Tankliner or supplied separately. In the latter case assembly kits will supplied. Should at any time unforeseen damage occur to your Tankliner, you can order kits from us so that you may carry out repairs yourself.
A substantial galvanised steel section roof, which incorporates an intergral inspection hatch. The roof is dsigned with 10 degree pitch whch allows sufficient dispersal of rainwater, whilst not significantly increasing the height at the centre of the silo.
This type of roof would normally be fitted in areas with strong winds of high snowloads and where safety and protection against vandalism is a high priority.
PVC reinforced Tensioned roofs:
In recent years, we have delivered quite a few silo covers, made of reinforced PVC foil. Base material is a polyester fabric with a PVC coating on both sides 850 gr per m2. To be supplied in green or gray. This material is very durable.
We mainly supplies so-called tensioned covers. Suitable for steel, concrete or wooden silos. These tensioned covers are made exclusively of the aforementioned high-quality reinforced PVC. On the inside of the cover Trevira straps are welded to the canvas, which is mounted to the ridge on an RVS (stainless steel) ridge plate. Around this a valance with an open hem is welded, which is drawn over the silo edge. In order to tension the whole, the tube is slotted in it. Straps are attached to the tube which can be tensioned with or without the aid of ratchets.
The silo cover is further tensioned by a centre column, which can be ordered separately on request. This centre column can be made of PVC or hardwood, in further consultation. The silo cover is further provided with a man hole and a mixing hatch.
Our qualified engineers are available to assemble this structure for you.
After a long period of extensive testing, we developed a new cover for Tanks and Silo's The so-called "DL- Aircover". The DL-Aircover is extremely suitable as a top sealing of all type of Tanks and Silo's made of Steel, Wood or Concrete.
The DL-Aircover is made of very high quality Polyester reinforced PVC fabrics, approved by KIWA. For the stability and the support is under the DL-Aircover a telescopic middle column installed. The correct shape and the stable construction is created by a fan that blows air continuous under the cover.
A cover of PP fabric about 200 gram a m2 for basins or tanks.
Blocks sunlight and so prevents the most of forming of algae.
A DELAFLOAT is manufactured using high quality polyolefin materials. The material consists of two layers ( one site in white colored ) with small air-filled pockets which allow for excellent floating capacity.
Liners for Basins/ Reservoirs/ Ponds/ Lagoons
DELAFLEX FOR WATER STORAGE:
15 year warranty
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, 0,75 and 1.0 mm thickness and DELAFLEX is welded in accordance with guidelines of the KIWA BRL-K 537.
PVC foil is often used for waterproofing ponds and water basins. This material is very flexible and therefore very easy to fold in any shape or model pond. The PVC foil is easy to weld and can also be glued with a special glue, in short, if a leak occurs, there is no need for specialists to attend to seal to the hole. Using a repair kit supplied by us, the repair can be personally executed by anyone who is a bit handy. And the price of PVC compares favourably to other materials suitable for ponds.
PVC foil is available in thickness of 0.4 mm up to and inclusive of 1.5 mm. In our factory standard rolls of foil are modeled by specially trained and qualified staff using up to date welding machines into prefabricated small, large and very large covers. We have a very large and modern factory where very large covers are made of 10.000 m2 or larger.
Annually we manufacture thousands of standard PVC foil rolls, welded in the factory to a width of 2 m, 4 m, 6m, 8 m, 10 m and 12 m folded and rolled up to a width of 2 m or 1.15 m. When ordered in sufficient quantity, the client can determine the length of the rolls. The standard colour of pond- or water basin foil is black, but other colours can be produced, when ordered in sufficient quantity by the client.
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.
We also supply and deliver 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.
