How to Install Plumbing and Electrical within ICF Forms

by NUDURA Blogger | Oct 17, 2016

For builders and contractors, figuring out how to accommodate plumbing within the wall can be a complex process, regardless of whether or not the building is constructed using ICFs. While common practice is to install waste lines with a drywall chase around them, NUDURA has accommodated many projects with waste lines right in the outside of the wall cavity.Hotknife Cut1

Typically, the lines are hot knife cut into the face of the foam in order to secure the plumbing within the system. In those instances, a builder can insert a 1.5-inch diameter waste line with coupling right inside cavity of the foam. However, when a deeper cavity is required, it must be accommodated by special attachments of foam inside the cavity before the concrete is poured.

An electrical chainsaw with a guide wheel can also coarse out the foam where the romax cable needs to be inserted, allowing it to be friction fit into the wall. Electrical boxes are inset and can be tapcon screwed into the back of the box to be held in position. The wires are simply run into the box the same way as standard electrical in a wood frame structure.
