Butyl Rubber Tank Liner

Our butyl rubber tank linings set the standard

by which all linings are judged

Available in standard irrigation or potable WRC drinking water quality grades and in a variety of thicknesses, our butyl rubber linings are so resistant to high-temperature variations, abrasion and UV light, that they outlast every other type of lining.

Heavier and more expensive than other linings, they pay for themselves by lasting for at least a decade, even in harsh climates.

Please see below for more information, or call us now on +44 (0)1386 760950.
