General Notes
Cintec grout anchors installed at 1000mm centres
into the fill behind the wall. Exact type and design
of anchors to be dependent upon the nature of the
fill . To be proposed by the installing contractor in
consultation with the manufacturer and agreed
prior to commencement of the works with the SE.
Concrete edge detailing to be repaired as
necessary and re profiled with a drip to help
reduce the amount of water running over the face
of the wall. It may be prudent for the top surface
to be re profiled
Stainless steel helical or Cintec grout
anchor (type JRA) bed joint
reinforcement installed one brick above
and below the line of grout anchors in

attached and provide additional strength
to the existing brickwork
1000mm

400mm
Existing render left on where not de bonded to
avoid unnecessary destabilisation of the wall. As
the render to remain is of varying type and quality
there is believed to be little benefit to using
flexible breathable lime render in keeping with the
remainder of the property.
Render is to be hammer tapped prior to repair and
any live or de bonded areas carefully removed
Render patch repairs to be in 1:2:9 cement : lime :
sand mix
Cintec ground anchors to be installed at
450mm centres and embedded to a depth

manufacturer and agreed prior to
commencement of the works with the SE.

brickwork to the front wall to be repaired and
openings formed into vaults reinstated upon
