Aluma-Block Expansion Joint Filler

Description

The Aluma-Block is a high-density, bitumen-impregnated fiberboard designed to fill expansion joints in concrete structures. It acts as a compressible spacer that handles the natural expansion and contraction of concrete slabs while providing a firm base for joint sealants.
