Prefabricated EPDM flexible tanks
As a result of its expertise in the waterproofing field and its investment in Research and Development Flexirub has been able to design the first range of flexible tanks in EPDM.
The new generation of ultra-resistant flexible tanksIn order to respond to the problems of collection and storage of rainwater Flexirub has taken advantage of its complete mastery of elastomers to create the first flexible tanks based on EPDM membranes.
EPDM is a material with remarkable qualities. It enables Flexirub flexible tanks to combine solidity, lightness and elasticity whilst benefiting from an exceptional service life.
EPDM flexible tanks may be used in agriculture, building and public works, or industry and also in the residential field for collecting rainwater, watering gardens, etc.
EPDM flexible tanks are a real revolution on the market and enable you to store and conserve liquids over the long term.

Installation OF A 3D EPDM flexible tank
Why should you choose an EPDM flexible tank prefabricated to measure in the factory and ready-to-install?
2 EPDM ranges for extreme solidity and resistance
- Reinforced EPDM (polyester grid and EPDM) for extreme solidity, perfect self-holding and limited distortion of the tanks
- EPDM for greater lightness and better elasticity of the tanks
The EPDM flexible tank is assembled in the factory by hot vulcanisation providing extreme resistance
- Indestructible welding by hot vulcanisation
- Service life of more than 50 years for the EPDM material
- Perfect resistance to bad weather, UV and extreme temperatures (- 40°C to + 120°C)
- Watertight storage preventing any pollution, evaporation and odour from the contents
Simple and fast to implement for temporary or permanent use
- Ready to install
- Lightness of the tank facilitates transport
- Interior or exterior installation
- Temporary or permanent use
Flexirub has developed a wide range of flexible tanks in EPDM or reinforced EPDM so as to meet all requirements.
Two performance levelsFlexirub has developed two additional types of flexible tank which meet distinct requirements.
- Reinforced EPDM
giving extreme solidity and ideal self-holding. These flexible tanks, composed of a polyester grid surrounded by two thickness of EPDM have the advantages of different aesthetics and limited distortion.
- Single-ply EPDM
for perfect waterproofing and better elasticity. These tanks only have a single thickness of EPDM, which makes them very flexible and therefore gain slightly in volume.
A wide diversity of volumes or made-to-measure25 references of EPDM flexible tanks have been designed to meet all requirements with volumes from 250 to 60,000 litres.
- The small volumes are perfect for individuals wanting to collect rainwater for domestic use or to water their gardens.
- The larger volumes will be more suitable for industrial use (storage, cleaning) or for agriculture (irrigation, rearing of livestock)
A packaged solutionFlexirub offers a packaged solution made up of a flexible tank in EPDM or reinforced EPDM accompanied by various accessories:
- A protective geotextile
- A PVC female (outlet) cap
- A PVC drain valve
- An overflow elbow
- A roll of Teflon

Flexirub offers you a range of professional accessories to facilitate installation, and finishings for the made-to-measure EPDM membranes.
PROTECTIVE GEOTEXTILEThis drainage liner is a geocomposite consisting of a tridimensional polypropylene strands sandwiched between two thermomolded filtering geotextile layers. It performs all of the following 3 functions: drainage, separation and filtration.
DRAINAGE LINERThis drainage liner is a geocomposite consisting of a tridimensional polypropylene strands sandwiched between two thermomolded filtering geotextile layers. It performs all of the following 3 functions: drainage, separation and filtration.
It is ideally used as part of the geomembrane waterproofing system. The drainage liner separates two materials and acts as a drain for a fluid or gas even in a high pressure environment and/or with a low gradient. It can replace or add to a gravel filter bed. Requires careful installation: be careful not to crush the filter, avoid countersloping, ensure continuity and make sure the filter is well covered.

SEPARATION GEOGRIDThe separation geogrid, or filtration grid, is manufactured from High- Density Polyethylene (HDPE). The material is highly-resilient while maintaining a degree of flexibility. For optimal efficiency, the geogrid must be used with a separation and filtration geotextile to retain the finest particles and avoid clogging.
The geogrid is mainyl used in waste-water treatment installations. It is used in particular to separate different granular layers. It is mandatory with a sand filter or other artifical soil filtration systems.
