Thin-Joint Systems for Aircrete Products

Thin-joint blockwork enables walls to be built very quickly without having to wait the conventional 24 hours for the mortar to set before further loading can be applied.

Celcon Celfix Mortar

Celfix Mortar is cement based and supplied as a dry, pre-mixed powder in 25kg bags. It has been designed to replace the traditional sand:cement mortar. Celfix Mortar starts to set within 10 minutes of application and approaches full design strength in just 1-2 hours. This enables blockwork to be built extremely quickly, and in the case of cavity wall construction independently of the outer leaf, which is normally brickwork.

Celfix Mortar is easily mixed on site by just adding the appropriate quantities of water. It is applied with a proprietary scoop or sledge, which will create a consistent joint thickness of 3mm.

Applications for Thin Joint Systems

• Internal and external leaf in cavity walls
• Solid walls
• Separating/party walls
• Flanking walls
• Partitions
• Multi-storey
• Foundations

The system enables the structure of a building to be built faster and to a better quality, allowing follow-on trades to start work sooner in a weatherproof environment, whilst retaining the flexibility of on-site construction.

Fully adopted as the preferred method of wall construction throughout most of Europe, this innovative and award-winning system has now firmly established itself within the UK.
