Abstract
A trenchless underfloor conduit system for distribution of electrical conductors, service lines and the like is disclosed. One or more spaced-apart duct members of reduced height dimension are placed over a corrugated deck. Covers are provided over selected valleys of the corrugated deck to provide at least one enclosed deck conduit extending transversely with respect to the ducts. Openings are provided in the deck conduit and overlying duct member to allow for communication therebetween. A substantially uninterrupted layer of concrete is provided over the deck and duct members and is secured to underlying supporting beams. The layer of concrete preferably has a minimum thickness of about two inches and is secured to the beams to increase the overall strength of the floor by utilizing a composite design without increasing the overall thickness or reducing the service line capacity thereof.
