Mastic Asphalt Tanking Grade Blocks 300x300

British Standard mastic asphalt is used in a wide range of construction applications; both new build and refurbishment, where a smooth, seamless, durable surface is required.

The product comprises suitably graded limestone aggregates bound together with an asphaltic cement (primarily refined bitumen) to produce a dense, voidless material. It cannot be compacted, and is laid by means of a hand float, rather than rolled. It is manufactured to BS 6925:1988, which encompasses roofing, flooring grades, tanking and a number of other grades for different applications.
