# How to Run Conduit Before Pouring Concrete
The best time to run conduit is before your pour the concrete slab. This allows you to install the conduit under the slab in a location where it is well protected. PVC conduit is typically used for these applications because it is weather-tight and doesn't corrode due to exposure to the acidic concrete. Installing conduit one size larger than you need is wise to accommodate future expansion of the electrical system.
