Offering a compressive strength of 7.3 N/mm², it’s suitable for load-bearing applications including foundations, multi-storey residential buildings, piers, and solid or cavity walls. Lightweight yet robust, it supports up to four-storey construction while providing excellent thermal insulation––helping reduce insulation requirements and enhance energy performance.

Applications:

• Foundations and load-bearing lower storeys in multi-storey buildings

• Inner and external leaf cavity walls

• Solid and separating walls

• Beam-and-block flooring and partition walls

• Piers, columns, and below-ground structures
