4-10mm LECA (Lightweight Expanded Clay Aggregate)


·       100% Genuine 4-10mm LECA
·       Creating Lightweight Intensive Soils & Subsoils
·       Reducing Point Loadings

LECA is the UK market leader for Lightweight Expanded Clay Aggregates. This material is produced in the form of a round shaped hollow clay pellet with a ceramic resistant exterior skin and a porous, lightweight, interior nucleus. Simply put, LECA is a super lightweight aggregate with a dry bulk density of approximately 350kg/m3.

Being totally inert with a neutral pH, our 4-10mm LECA is ideal for creating lightweight intensive soils, subsoils and soil variations, where point loadings need to be reduced. LECA contains no harmful substances or gases and is absolutely 100% neutral whilst its longevity is estimated to be in excess of 100 years. In addition to its lightweight, drainage and aeration properties, LECA also acts as an insulation when added to soils.

Whilst many of our competitors utilise cheaper, inferior substitutes, all Bury Hill Lightweight Intensive Soils are blended using ‘genuine’ LECA.
