What is a C-61 / D-6 Concrete Related Services License?
What are Concrete Services?
The D-6 Concrete Services License classification covers a wide range of concrete services including:
C-8 Concrete license vs D-6 concrete services license
California has two different licenses for contractors that work with concrete:
- The C-8 License: Concrete
- The D-6 License: Concrete Related Services
D-6 Concrete Related Services License
Contractors specializing in concrete pumping typically work directly with a property owner or C-8 License holder. However, they may also function as subcontractors as part of a larger construction project.
In a construction setting, a General Contractor may hire a concrete pumping service specifically for their expertise and equipment.
As a result, a general contractor ensures that the concrete pumping phase of the project is executed correctly.

The Contractors State License Board (CSLB) is the governing body for all contractors in the state of California. Their sole responsibility is to protect the consumer public.
They ensure that anyone charging over $500 for construction services is qualified and registered with the state.
The C-61 / D-6 concrete services contractor license is issued to contractors by the CSLB.
When making alterations to or around structures built before 1978, contractors must know how to contain lead paint if it is present.
Lead paint can travel miles through air, rest on soil, and enter air ducts causing potentially fatal respiratory damage.
Concrete services contractors looking to build profitable businesses must position themselves as experts and the authority within their industry.

It is critical for concrete services contractors to be able to read designs and symbols on construction blueprints.
If installation or repair is part of a larger project, being able to execute their duties within the larger scope of the job is essential.
They also communicate what materials were used for its construction. Reading blueprints is an invaluable skill for all tradesman but can be especially important for concrete services contractors.

C-61 / D-6 Concrete Services Contractor License Requirements
D-6 concrete services contractors in California must prove a minimum of 4 years journeyman level experience and pass a law exam.
To qualify for an exam date you must meet the the following requirements:
What is journey level experience?
Journeyman level experience means that you have worked unsupervised full time for a concrete pumping service, or for a contractor that holds the D-6 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 Qualifying Individual
The following people may act as a Qualifying Individual when applying for your D-6 Concrete Services License
How to fill out the Contractor License application
In addition, your Qualifying Individual will need to provide a brief but detailed description of your knowledge and skillset.
The way this description is written is critical to whether or not your application gets accepted. For example:
“Sam made our patio look great” is not descriptive enough.
The explanation must look more like:
"Ted has installed pre-cast pavers, he has cut, stained and dyed concrete. He has operated a line and boom pump. Ted has applied gunite and installed reusable concrete"
Most importantly, the description written by your qualifying individual has to include the core skills required a concrete services contractor.
Work experience for the Contractor 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 which include:
- Tax Returns
- Check Stubs
- 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.
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 some where they got their test date much later.
The most common reasons your application would get held up are:
- Time of year (processing time slows down during the holidays)
- Criminal History
- Proving Experience
- Mistakes on your application
Contractor License Costs
The Current CSLB fees are:
Can you get a Contractors License with a Felony in California?
Having a criminal record in no way stops you from getting a concrete services contractor License. Thousands of tradesman get licensed in California each year despite having criminal records.
The key is to be honest on the application, even if the felony or misdemeanor happened years ago and even if it was expunged.
BE 100% HONEST ON THE APPLICATION, because they will see everything anyway when you do fingerprinting. The CSLB handles criminal records on a case by case basis.
Remember, their responsibility is to protect the public. Typically the CSLB is most concerned with Fraud, Embezzlement and Forgery.

Occupational Safety Hazard Association
Statistically, 21% of all work-related fatalities are in construction.
That equals about 1 and 5 worker deaths on average.
Professionals in the landscaping and tree removal industry must take pre-caution to prevent falls and injury.
Construction can be dangerous, especially if your workers are not properly trained. For employment with a concrete services company you may be required that you have completed some level of OSHA training.
