EPDM Rubber Liners - (Ethylene propylene terpolymer)

Description —
EPDM is a durable geomembrane with a 20-year proven performance history in exposed applications, such as ponds and lakes, canals, fish stock ponds. It can be self-installed in residential water features.

EPDM exhibits high tensile strenth and excellent resistance to punctures, UV radiation, weathering and microbial attack. It is also highly flexible material with a low co-efficient of thermal expansion and contraction, enabling it to lay flat in a wide range of temperatures and terrains thereby conforming well to irregularities in the subgrade. EPDM is manufactured and installed as liners, caps and covers in environmental containment applications worldwide.

EPDM exhibits excellent elongation characteristics and does not require a soil cover. EPDM is delivered to the project in panels that are up to 50' x 200' (10,000 sq.ft.) This product is available in custom sizes as well.

45 and 60 mil EPDM are the most popular materials in the custom waterfall and decorative pond market due to its high degree of flexibility. Its resistance to weathering and UV exposure comes into play around the waterline where the membrane can be exposed with rising and falling water levels. Its ability to expand and contract, while maintaining its integrity as water levels and temperatures change is another design asset.

Reinforced EPDM is also available via special order.

Field seams: This product is seamed in the field using primer and 6" seam tape. It can be fabricated on a limited basis. Please contact CLI for more details.

(This process is very similar to patching an automotive inner tube. First, an abrasive pad roughens up the material to provide a better gluing surface. Next, a seam-priming adhesive is applied followed by a 6"-wide adhesive-back tape over the field weld. The seams are consistent and permanent.)Contact CLI for installation estimates.

Design Notes:
As with any exposed membrane, a safety bench and edge treatement are recommended. EPDM may be adhered to concrete.
