Certification

Pervious concrete is not easy.  It is not easy to make and it is not easy to do all of the steps necessary to properly install it, so we have developed a class that involves eight hours of classroom instruction and outdoor learning lab. CMS, co-developer of the very first certification program in 2003, offers certification classes with real merit.

Delivered via PowerPoint Presentation, examinees are taken through the history of pervious, design criteria, mix design insights highlighting differences in aggregate, cementitious material and admix choices from around the country, equipment choices for placement (pros and cons) and proper curing (including traditional methods as well as internal curing and spray on applications). There are highlights of successful installations as well as those of jobs that became problematic as well as numerous videos of actual installations to give a firsthand view of what to look for out in the field. After the six hour class, all attendees will then get two hours of hands on experience placing and finishing pervious concrete using various tools and techniques.

The purpose here is not to tell any contractor what they must do but show methods that have proven successful and let them decide what works best for them. One example would be that for curing pervious they will learn how to cover the finished product with 6 mil poly as well as the two step method using painters poly followed by crossrolling and then securing with a 4 mil as well as how to properly apply a spray on curing compound without any poly.

Following the test placements, the examinees will return to the classroom having actually handled pervious concrete, complete a review session and then take a written test. Anyone passing the written test with a score of at least 75% will be granted their certification. Upon successful completion of the test placement and written test, the names and levels of the individuals will be posted online. Perhaps even more important that the classroom experience is the fact that now, the installers of pervious concrete will have a resource where they can have their proposed mix designs evaluated before a job starts and if situations come up in the field, they will be able to call and get a quick response to help solve the issue.

Last but not least, in the event of a dispute between and owner and a CMS Certifier Technician/Installer/Craftsman there are instances where the certified personnel may lose their certification based on the decision of the CMS Certification Review Committee. Complete details may be found here. No matter what level of certification you are looking to get, we can help you be prepared for the test and then be on-site with you to make sure that what you learn in the class is properly applied in the field.

There are five levels of certifcation:

Pervious Concrete Technician

Is suggested for entry level pervious installers, batchmen, concrete salespeople, quality control technicians, architects, engineers and other specifiers of pervious concrete. Subjects include: proper placing, compacting, finishing, edging, jointing, curing and maintenance of pervious concrete.

Pervious Concrete Installer

Designed for pervious installers who have at least three (3) jobs , of a combined 10,000 sf of successful pervious installations.

Pervious Concrete Craftsman

Designed for pervious concrete installers with a high degree of experience able to document 3000 hours of pervious experience or complete a performance evaluation and document 1500 hours of experience.

Pervious Concrete Testing Technician

An additional certification that covers the basic technician information as well as current A.S.T.M. pervious testing standards.

Pervious Concrete Batchman

An addtional certification that covers the basic technician information plus teaches how to properly design a well balanced mix design and key quality control issues at the plant and how to properly batch and temper pervious concrete into a mixer.
