These blocks are laid onto a mortar bed in the normal
manner on a concrete foundation. They offer a labour saving
alternative to a traditional foundation because the size
of the block gives the choice of forming either a 285mm
or 300mm wide solid foundation wall, from a single leaf
of blockwork. Thus removing the need to create a cavity
or use wallties and reducing the quantity of mortar used.
Strength, combined with lightweight block, ensure foundation
walls can be built fast, strong, safe and economically.
OPTION 2: TRADITIONAL FOUNDATION
Two skins of blockwork, usually 100mm Intercrete or Interlyte
7N laid in the normal manner onto concrete foundation.
The cavity width would be set out to accommodate the wall
as required in the superstructure, the leaves would be tied
and the cavity filled with a lean mix concrete.
The top of the foundation level should be accurately set
to achieve full block coursing up to DPC or ground floor
level.
Blocks allow for fast on site working one block is equivalent
to six bricks.
