EPDM Liner Kit

Whilst not possessing the same longevity as Butyl liners, our EPDM offers a more budget friendly option, making it a popular choice particularly amongst the agricultural and horticultural sectors. Manufactured at our UK factory to suit any tank size and shape, with stock options available ranging from 22m³ to 93m³.

What is EPDM?

Ethylene Propylene Diene Monomer, or EPDM as it is commonly known, is a synthetic water-resistant rubber material. Our EPDM is a cost-effective flexible rubber material and, although not as long-lasting as Butyl, possesses relatively high durability as well as resistance to UV exposure, weathering, and chemicals such as:

• Alkalis
• Strong acids
• Natural oils & fats
• Alcohols
• Organic solutions

Key Properties

Our EPDM rubber has the following properties:

• Seams are all vulcanised to produce 100% impermeable liners up to 1200m2 in area.
• A high elasticity of 300% stretches over the original length without damaging the material properties, allows the membrane to adjust to any base settlement.
• Small damage and leaks can be repaired using cold-bonding tape on site.
• Our EPDM rubber is a very stable polymer and does not leach any chemicals into the contents of a tank.

Variations

Butek Tanks EPDM liner kits are manufactured from 1.00mm EPDM as standard. However, we can offer the following material variations:

• plain rubbers of thicknesses between 1.00mm and 1.5mm
• scrim-reinforced EPDM rubber with tensile strengths of up to 550N/50mm.
• WRAS-certified EPDM rubber for drinking water applications.

Lifespan

Despite not being as long-lasting compared to Butyl liners, our EPDM tank liners have an anticipated lifespan of approximately 25 years. We offer a 10-year warranty on all water storage EPDM liner Kits.
