Liners & Sealants

Here at Angel Koi & Aquatics we carry and can source EPDM and Butle Lners and a range of sealants. The selection below is simply demonstrative of the range we carry and feel free to call in or contact us for anything specific.

EPDM Liners

The EPDM material is especially suited for small to medium sized ponds, or for prefabricating into regular shapes for formal Koi ponds, water features, rills etc. High elasticity, irrespective of temperature, means the material will return to its original shape after stretching, and will mould itself easily to the shape of the pond.The material is highly resistant to UV degradation.
