Context

Contractor Canning Ericsson used H+H’s Rå Build method for the construction of a 3-storey apartment block in Brighton.

The contractor was already familiar with the Rå Build method of large-format aircrete blocks, the Thin-Joint System and quick-drying Celfix Mortar having used the modern construction method on several of its previous schemes.

Client feedback

Michael Alderton, Director of Canning Ericsson said: “We decided to use H+H’s Thin-Joint System again because it is quick and easy to use, it goes up fast and gains structural strength quickly; it’s a really great system. The biggest benefit of using H+H’s Thin-Joint System is the ability to use large-format 630mm x 250mm x 100mm wide Jumbo Bloks, which enables the walls to be constructed a lot quicker.

The blocks are relatively lightweight and easy to cut to shape in comparison to denser blocks. “The footings were in place mid-October 2014 and by the end of December 2014 we had built the block using aircrete with cast in situ floors and fitted the roof.”

Product benefits

In addition to speeding construction the aircrete blocks also help improve the walls’ thermal performance, reduce sound transmission between apartments and improve the airtightness to help the scheme meet the Code for Sustainable Homes Level 3 criteria.

Using the Thin-Joint System also helped Canning Ericsson overcome the limited storage facilities on the compact site because the Celfix mortar is delivered bagged and can be mixed in buckets, which eliminates the need to store sand and other materials on site.

  • Provides a fast watertight masonry shell to enable internal trades to start sooner
  • Meets or exceed Part L and Part E of the Building Regulations
  • Simplifies the construction process
  • 80% recycled material
  • A+ rating in BRE Green guide
  • Excellent thermal and acoustic properties
  • All components for the Rå Build method available off the shelf
  • Block-work is highly adaptable, allowing for any last minute design changes
  • Air permeability of 0.12mÑ/hr/mÇ
  • Celfix mortar can be stored within footprint of building - small quantities mixed as required
  • Class 0 rating for surface spread of flame
