As an experienced film processor, NPI has supplied film assemblies for excavated basins for many years. These excavated basins are made up from earthen walls, lined with one of our high-quality films with a long lifespan. Excavated basins have many applications and multiple benefits. These include the large storage capacity, the flexibility in shape and size and the low investment cost per cubic metre. Read more about our excavated basins here.
Applications and benefits
There are many applications for excavated water basins, from agriculture and horticulture to civil engineering projects, environmental and leisure projects. However, the same benefit applies to all excavated basin applications: the capacity to store large volumes of water. A summary of the benefits:
- Prefabricated liner, welded inside under perfect circumstances
- High degree of flexibility in shape and size
- Low investment cost per square metre
- Quick installation on site
As one of the longest-established film processors, NPI specialises in the supply of basin films. The basin film type is determined by the subsurface, the type of water to be stored and the wishes of the end user.
We can produce bespoke LDPE, PVC and polypropylene films of up to around 10,000 m² in our production hall. These can be welded on location if required. If desired, our specialist assembly teams can survey the site, supervise the rolling out of the film, handle the welding on location, installing the bespoke outlets and installing embankment protection.
For excavated basins in the horticulture sector, we advise protecting the side of the basin embankment with embankment protection. This protects the film on the embankment against UV light, wind, weeds and vermin. We also offer several options for covering the water basin. With a cover in place, algae cannot form, evaporation is prevented and leaves etc. cannot contaminate the basin. This ensures optimal water quality and prolongs the lifespan of the storage system!
