The latest edition of NHBC’s technical Standards
have come into effect.
The new Standards are applicable for every new
home covered by an NHBC warranty, where foundations are begun on or after 1
January 2022.
NHBC’s dedicated Standards team have spent last
year reviewing all the technical content of the Standards and working
with stakeholders from across the industry to ensure they remain
accurate and relevant.
Updates to the new version include Chapter 3.1
‘Concrete and its reinforcement’ reflecting industry guidance on concrete mix
proportions by volume, minimum specifications for general purpose concrete
mixes and aggressive chemical environment for concrete, as well as a site and
design guide for concrete elements in the ground.
There are also updates to Chapters 6.1, 6.2 and
6.3 ‘Walls - external masonry, timber frame and internal’ to reflect
requirement changes and a minor technical amend to 9.2 and 9.3 – ‘Floor,
ceiling and wall finishes’.
NHBC’s Standards and Policy Manager Mark Russell
said: “We hope that the industry will find our new Standards a useful
reference point as we all strive to deliver safe,
high-quality new homes for the generations of people that will live
in them.
“There are several changes highlighted in the
Standards this year which will ensure they remain as relevant and accurate as
ever.”
