Install Electrical Conduit and Concrete Patch

What happens here

Before installing plumbing, metal electrical conduit is laid in the excavated trench. The presenter uses metal elbows and straight sections, connecting them. According to electrical code for in-house slab installations, the conduit must be below the concrete surface with at least a sliver of dirt or sand covering it before the final concrete pour. Quick-setting concrete mix is poured directly into the trench over the conduit. Water is then added and mixed in place using a trowel, which allows the concrete to settle into all crevices around the conduit, ensuring a solid, uniform fill. The concrete is smoothed level with the surrounding floor.

Goal: Lay metal electrical conduit within the concrete trench and then backfill the trench with quick-setting concrete, ensuring the conduit is properly covered.
