Lightweight Aggregates

Argex LWA

8-16mm Expanded Clay Bulk lightweight Mix at 1.5n/mm2+ pellet strength

Used as an ultra lightweight backfill or foundation material where there are poor soil conditions or where heavy material cannot be used, Argex LWA is ideal for filling behind retaining walls, bridge abutments, soil improvement areas and as a general geo-fill lightweight building material.

It is equally suitable as backfill material in sewage trenches or around pipes, behind steel quay walls and on bridge decks and parapets. Can be used in and out of water and forms maximum stability thanks to its bearing capacity, high internal friction angle and unlimited life span.

Lightweight Concrete Mix for Screeding

Ideal for screeding, a blend of lightweight clay aggregate and concrete provides lightweight concrete mix for a smooth finish in construction projects.
