EPDM geomembrane rubber liner exhibits high tensile strength and provides 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, allowing it to lay flat in a wide range of temperatures and terrains thereby conforming well to irregularities in the subgrade. This linear is available in thicknesses from 30 to 45 mil. It is used in ponds, lakes, canals and fish stock ponds.

Epoxy is a thermosetting epoxide polymer. It also called polyepoxide. It cures when mixed with a catalyzing agent or hardener. Most common epoxy resins are produced from a reaction between epichlorohydrin and bisphenol-A.

Epoxy adhesives are suitable for high-strength bonding of a variety of materials and have excellent resistance to harsh environments, chemicals, and water. It is used to produce satisfactory joints between nylon and metal, wood glass and leather. It is applied with a wooden paddle or spatula. They will cure at room temperature in 24 to 48 hours.
