Company History

Hector Carrillo Sr., Hector Carrillo J.R., Hector Carrillo III., Daniel Carrillo Sr., and Daniel Carrillo Jr. have over 70 years combined experience and knowledge in the concrete industry, as well as decades of hands on experience of all aspects from set-up, pouring and placing of structural custom concrete.

In the day to day concept of concrete construction the care and detail that is entailed in the setting up of concrete forms, there has always been challenges and creativity that was needed to accomplish a finished product that not only has an excellent look but something that the customer would appreciate and have years of enjoyment through this finished product, i.e. foundations, custom steps and many forms of cantilever applications.

Through the years the Carrillo’s have been able to accomplish beautiful concrete finishes with thousands of happy customers, but in the endeavor to take custom concrete to another level of detail, we are required to pay attention to the smallest details.

The Product History

To give a little history of how this product came to be, the necessity of custom forms and a method to attach them has been around for hundreds of years actually since the invention of concrete itself, if not since before that time with the hardened mud and clay bricks homes.

 For centuries man has used hammers and nails to put things together, for any and all types of uses, at some point in history wood frames were used in the past just the way wood forms are used in the present and will be used in the future for the forming of concrete placement. Nails were used that only had a single head, these nails accomplished there purpose because the number one use for them was to keep wood forms together as fresh concrete was poured into them or up to them to create a finished concrete product.   

These single head nails worked to perfection until it was time to remove the forms that were holding the concrete. So the double head nail was created out of necessity, the double head nail made the removal of the form material simple because a portion of the nail stood out were a hammer or nail remover could easily grab a hold of the nail and pull it out.

In the application of concrete steps and all cantilever forming, wood or prefabricated forms always needed to be removed to accomplish a finish that is to the customer’s liking. In order to remove the forms a considerable amount of pressure is placed on the forms and concrete to pull out the nails, this sometimes damages the actual green (fresh) concrete which can be detrimental to the finish product resulting in a removal and redoing of the concrete, which will result in the costly and unsightly product.

The Cordless Method

What would be a better method of attachment of the form material? That actually has already been established, with the invention of the cordless screw gun, because of this wonderful and useful tool many in the industry as well as the Carrillo’s have begun using screws to attach the concrete forms because of the ease of use as well as speed and the ability to attach and most importantly the Removal of the concrete forms without applying unnecessary pressure on the green (fresh) concrete. 

A better method is not always the best method as was noted earlier with nails, single head nails were very difficult to remove therefore double headed nails were created.

Such is the case with the single head screws, a very good method better than nails but can be difficult to remove because of the single head, this head can get counter sunk which makes it very difficult to find and often gets covered by spilled concrete over the form material, such things as covering the screw head with tape has been a temporary solution but still does not accomplish a better product.  

The Top Hat Duplex Screw

The Carrillo Drive Screw accomplishes a better product and more, the Carrillo Drive Screw is a concept that the Carrillo’s have invented to solve many concrete forming application and can be used in all types of concrete forming.

The Carrillo Drive Screw is a double headed screw that will act and perform similarity to a double headed nail but in a screw application easy to use easy to find. Saves time and costly tear outs due to damage caused by pressure put on the forms from pulling out nails. Another advantage to the Carrillo Drive Screw is that they are reusable, unlike a nail that can only be used one time.

We feel that this screw will revolutionize not only the concrete industry but can be used in many other construction and household application, i.e. picture hangers, and can also be used when installing speakers in cars its known that screws often become striped, temporary uses to construct items that will be taken apart at a later date. Also the film industry could use and save, they also assemble and disassemble prop’s with screw’s and also the convention center’s they also assemble there booth’s with screw’s and as mentioned before our screw’s are reusable.

Our Team

Hector and Daniel Carrillo have over 80 years combined experience in the concrete industry. Having been licensed contractors since the early 1980's, their experience with the necessities of concrete set-up work brought them to configure, after much trial and error, the Duplex Screw, which was invented and awarded a patent February 3, 2009.
