Abstract
A method of constructing multiple conduits in building foundations that eliminates the process of core drilling after the foundation has been poured and set. This method creates optional openings for possible future connections. The process uses removable conduit molds installed before the foundation is poured. Once the foundation has set, conduit molds are removed to explose conduits in the foundation as needed.
Claims14
A method for pre-casting conduit holes in a building foundation, the method comprising:
- a) installing a plurality of concrete molds around the building foundation, wherein the plurality of concrete molds are configured to support a poured foundation concrete mix;
- b) installing a plurality of lightweight conduit molds within the plurality of concrete molds at locations designated for conduits within the building foundation, wherein each conduit mold comprises a unitary cylindrical bar, a cylindrical central ring surrounding the cylindrical bar, and a rubber surface on each end of the cylindrical bar;
- c) pouring the foundation concrete mix in the plurality of concrete forms around the plurality of conduit molds;
- d) setting the foundation concrete mix;
- e) removing the plurality of concrete forms, wherein the rubber surfaces of each cylindrical bar are substantially flush with an interior and exterior wall of the building foundation;
- f) removing the conduit mold from the building foundation to open a conduit hole;
- and
- g) installing a conduit within the conduit hole in the building foundation, wherein the conduit mold is removed from the foundation wall through drilling.
