Fixtures
Electrical Fixtures:
PRODUCT MANUAL
Small fixtures can be mounted on finished walls using appropriately sized drywall anchors. Use “Grappler” fastening
plates behind drywall for additional holding power. Larger fixtures should be fastened to expansion anchors set through
the foam panels and into the concrete (see Cabinetry and other Heavy Items on Page 94).
PLUMBING
Plumbing pipes and fixtures may be installed in conjunction with Quad-Lock in several ways (similar to Electrical
Installation / previous section):
Pre-Pour Method:
The supply and waste pipes may be installed, if permitted structurally, within the concrete cavity prior to placing concrete.
Ensure all plumbing is protected from direct contact with the concrete. Pressure tests of all cast-in-place plumbing should
be completed prior to placing concrete.
If some minor displacement of concrete is permitted structurally, plumbing chases can also be created by using
oversized plastic pipes cut lengthwise in half. Wire the pipe into place with the cut side along the inside of the wall cavity.
On the outside of the panel, wrap the wire around a small piece of wood to keep the wire from cutting into the foam.
Mark the location of the chase pipe on the outside of the wall with a felt pen for cutting after the concrete pour.
After-Pour Method:
Supply pipe may also be set in grooves or chases routed in the foam after placement of the concrete. Pipe locations
must conform to the minimum setback requirements of applicable building code unless protective measures are utilized.
Anchor plumbing directly to the concrete as required. After inspection, spray foam may be used to refill the grooves.
Anchor plumbing fixtures directly to the concrete or to blocking attached to concrete.
