EABASSOC

EABASSOC Lightweight Foamed Concrete is a versatile construction material made from sand, cement, water, and foam. With dry densities from 400 to 1600 kg/m3 and compressive strengths from 1 to 15 MPa, it offers excellent load spreading characteristics and fast workability. This non-hazardous material is ideal for road widening, sub-bases, repairs, soft ground applications, ground stabilization, and emergency or planned void filling.

  1. EABASSOC LIGHTWEIGHT FOAMED CONCRETE for Roads and Geotechnical Applications

  2. EABASSOCLIGHTWEIGHT FOAMED CONCRETE • Made from Sand, Cement, Water & Foam • Dry Densities from 400 to 1600 kg/m3 • Compressive Strengths from 1 to 15 MPa • Mix Designs chosen to optimise density, strength and cost

  3. Advantages of Foamed Concrete • Lightweight...does not impose large loadings • Does not settle • Free flowing • Enables Fast Work • Excellent load spreading characteristics • Reliable quality control • Once placed requires no maintenance • Low water absorption over time • Resistance to freeze-thaw cycle • Non-Hazardous

  4. Typical Uses for Roads • Trench Reinstatement • Road Widening (Sub-Base) • Road Building on Soft Ground (Sub-Base) • Road Repairs • Bridges over Drainage Channels
