Do you need a license to pour concrete?

The answer is yes!

This step-by-step guide will break down everything you need to know about the licensing processing in California!

How to get a Concrete License

To get a Concrete License in California, you must prove a minimum of 4 years of journeyman level experience.

You must also pass a two-part state exam with the Contractor State License Board. 

To get an exam date you must meet the following requirements:

  • Be at least 18 years of age
  • Have a valid Driver's License or USA Issued Identification
  • Have a Social Security or ITIN #
  • Cannot Currently be on probation or parole

You must also have:

  • 4 Years Journey Level Experience
  • Have a Certifier sign off on your experience
  • A way to prove your experience if the CSLB asks

What is Journeyman Level Experience?

Journeyman-level experience means that you have worked unsupervised full-time for a concrete company, or contractor that holds the C-8 License.

  • A journeyman can perform all of the duties associated with his or her trade.

The CSLB will want to see four full-time years over the last ten years. 

The years do not need to be consecutive, but they do need to be four years in total. 

Signature of A Certifier

The following people can sign off on your experience

  • Licensed General Contractor
  • C-8 License Holder
  • Fellow Employee (within last 10 years)
  • Current or former Supervisor (within the last 10 years)
  • Business Associate
  • Fellow Journeyman
  •  Union Representative

Proving Your Work Experience for the Concrete License

You must be prepared to submit documentation supporting the experience you claim to have. 

The Contractors State License Board gives you a few ways that you can prove your experience.

  • Tax Returns
  • Check Stubs
  • Contracts
  • Material Order Invoices or Receipts

The CSLB  receives thousands of applications per month so there is a good chance they won’t document your experience.

However, if you are one of the applicants that get reviewed you will need to be ready to submit something. 

The CSLB does not accept pictures of projects.

Filling out the Concrete License Application

The person you choose to be your Qualifying Individual needs to write a description of your work experience.

For example:

“Hank has done concrete work…” will not work

The CSLB will want to see something: 

“Hank has mixed mortar, done forming, placed and poured concrete, constructed retaining walls, and foundations”

What is a C-8 Concrete Contractor?

“A concrete contractor forms pours, places, finishes and installs specified mass, pavement, flat and other concrete work; and places and sets screeds for pavements or flatwork. This class shall not include contractors whose sole contracting business is the application of plaster coatings or the placing and erecting of steel or bars for the reinforcing of mass, pavement, flat and other concrete work” – CSLB.GOV

Anyone charging over $500 for concrete projects needs to have a C-8 Concrete Contractor License.  

The C-8 License is an essential license in the eyes of the state of California.

Concrete is a trade that is critical to the foundation and functionality of most structures in the developed world. 

Duties associated with the Concrete License

A concrete contractor legally is not allowed to bid on a project that falls outside of the spectrum of general concrete-related work.

Duties include:

  • Demolition
  • Excavation
  • Measurement 
  • Pouring and Mixing Mortar
  • Retaining Walls
  • Foundations
  • Slab Work

  • Installing Reusable Steel Concrete
  • Post Tensioning Work
  • Sawing and Breaking
  • Curing Concrete
  • Forming
  • Tamping Finishes
  • Pouring Concrete

What jobs can you do with a C-8 license?

Concrete Subcontractor

Concrete Companies that hold the C-8 License often function as an independent unit subcontracted by a General Contractor.

They perform specific duties associated with a construction project.

75% of the state exam for General Contractors includes questions specific to concrete. 

Meaning, it is a critical skill set for anyone overseeing a full construction or remodel project.

  • Foundations
  • Driveways 
  • Parking Lots

The General Contractor reports directly to the client and is in charge of the overall project and its day-to-day operations, including subcontractors and job site safety.

Application Processing, Fees, and Criminal History

The time it takes to get your application processed and assigned a test date fluctuates throughout the year.

Typically you can expect:

  • 6-8 Week Application Processing Time
  • 3-4 Week wait for an Exam date

I have seen some situations where applicants got their test date sooner and somewhere they got their test date much later.

The most common reasons your application would get held up are:

  1. Time of year (processing time slows down during the holidays) 
  2. Criminal History 
  3. Proving Experience
  4. Mistakes on your application 

Application Costs for the C-8 Concrete License

The Current CSLB fees are:

Having a criminal record in no way stops you from getting a C-8 Concrete License.

I have personally helped guys with all types of criminal records obtain multiple licenses.

The key is, to be honest on the application, even if the felony or misdemeanor happened years ago and even if it was expunged.

See the CSLB's verbiage below:

Just because you have been convicted of a crime does not automatically mean your application will be denied. CSLB's Criminal Background Unit (CBU) reviews all criminal convictions to determine if the crime is substantially related to the duties, qualifications, and/or functions of a contractor. Since no two conviction records are the same, they are reviewed on a case-by-case basis. The criteria used by CSLB include whether the crime shows the present or potential unfitness of an applicant or licensee to perform the functions authorized by the license in a manner consistent with the public health, safety, or welfare. In addition, CSLB reviews and considers any evidence of rehabilitation submitted by the applicant or licensee. Please see the above link to the California Code of Regulations sections 868 and 869 for more specific information on the criteria for determining substantial relationship and rehabilitation.

BE 100% HONEST ON THE APPLICATION, because they will see everything anyway when you do finger printing. 

The CSLB handles criminal records on a case-by-case basis. Remember, their responsibility is to protect the public.

In my experience, they are primarily concerned with criminal charges associated with:

  • Fraud
  • Embezzlement 
  • Forgery

In the state of California, you are required to divulge any criminal charges when applying for any state license.

Even if they have been expunged. 

You will need to be prepared to submit anything they ask for regarding your criminal history.
