Get properly licensed to operate a concrete pumping service as a California contractor

Steps

1. Confirm that concrete pumping is classified under the D-6 (Concrete-Related Services) classification, which CSLB describes as covering post-tensioning work, concrete sawing, coring, gunite application, and 'operates a concrete pumping service' — not under the general C-8 (Concrete) classification.
2. Check CSLB's classification library page for D-6 to read the full scope language and confirm concrete pumping is explicitly named there.
3. Note that D-6 is administratively tracked as a sub-category of the C-61 Limited Specialty classification, so the application will reference C-61 with the D-6 specialty designation, not a standalone 'D-6' license type.
4. Apply for the C-61/D-6 classification through CSLB's standard contractor license application process, including the trade exam or exam waiver, bonding, and experience-verification requirements that apply to C-61 sub-classifications.
5. If the business also performs general concrete flatwork or structural concrete work in addition to pumping, evaluate whether a separate C-8 classification is also needed, since C-8 and D-6 cover different scopes of concrete work.
6. Before bidding pumping-only jobs, verify current classification scope on CSLB's site, since classification definitions are set by Board policy and can be updated.
