Owner and founder Mark J Giarritta’s love of concrete comes naturally, being born into a family that have been Masons for nearly 100 years.

Mark’s great grandfather Frank Jeffrey Giarritta the 1st tiled the lunar pools at the Hearst Castle as one of his crowning achievements in tile masonry and his Uncle Frank Jeffrey Giarritta the 3rd has been a well respected concrete contractor in placer County for over 30 years.

Mark started with his uncle learning the trade at 17 in 1998. He was taught to always create the highest quality concrete work possible, by making near perfect square foundations and taking a little extra time to do clean finish work.

At the colossal concrete company we do our best to make sure that our employees receive a generous wage for their hard work and we take pride in the fact that our products are 100% hand crafted in America by Americans.

If you have any questions about anything at all don’t hesitate to give us a call.

“We were going through some rough times with our employer when you did that project, so it wasn’t an easy expense. It was worth it though – it really adds a nice touch to that house.

Over the two years after that when I met Trick or Treaters at the door, at least 20 comments were made about how cool the concrete was – usually by fathers escorting their kids.” – Andrew (Idaho Falls, Idaho)
