Installation in brickwork
DIN 1053, Sheet 1, Section 3.5 specifies that recesses and channels may be made in brickwork, provided they do not affect the
stability or load-bearing capacity of the structure. In areas subject to high outside temperatures, thermal insulation measures must
be applied (e.g. lagging of heating pipes). The key pipe dimensions to be taken into account when installing Wavin AS+ in brickwork
recesses can be found in chapter 4 of this manual.
Installation in concrete
Like all hollow items, pipes are subject to buoyancy load for-
ces when installed in concrete. All materials used in the pipe
structure must be able to withstand these buoyancy loads. To
this end, we recommend filling the pipe with water before fit-
ting suitable fixing clamps to the existing steel reinforcement.
Wavin Soil & Waste pipe systems (pipes and fittings) can be
set in concrete immediately after installation. There is no need
to account for any thermal length-expansion of the pipes
once they have been installed in keeping with the installation
instructions. The pipe sections should be secured properly
so as to prevent any change in length, particularly during the
pouring of concrete.
To prevent liquid concrete from seeping into the joins. seal
the sleeves with adhesive tape (e.g. Tesa Krepp). Exposed
pipe ends should also be sealed off. Pour the concrete into
the area around the pipe and allow it to flow into the working
space. When using a concrete vibrator to compact the con-
crete, be sure not to come into direct contact with the pipe. If
noise-insulating measures are required, insulate the pipe with
suitable lagging material before starting work.
