In 1999 Mike McDonald founded McDonald Waterproofing and Restoration with a vision to bring honesty, friendliness, and concrete repair services of the highest quality to Colorado’s Front Range. Established on straightforward values of integrity, doing the job right the first time, having fun, and friendships with team members and clients, we’ve built a solid, trusted reputation throughout Colorado.

January 2020 marked the company’s 20th anniversary. Along with achieving that milestone, and in anticipation of the upcoming sale and transition, the company was renamed HEXA – a McDonald Company. The new name represents the excellence and efficiency of the team and the strength under pressure that characterizes our specialty repair solutions.

Now the company marks yet another milestone. Mike McDonald has announced his retirement and has sold the company to Joe Keller. Joe has worked in the concrete repair industry more than 20 years, many of those spent with Mike, helping grow HEXA into the company it is today. He has served the last three years as President and COO, building on the vision that Mike created more than two decades ago.

“I’m proud of this company and the entire team who helped us get to where we are today,” said Mike. “Joe is a strong leader who has been instrumental in our growth, and it is with great pride and confidence that I pass the baton, and ownership of this great company, to his continued leadership.”

“I’m honored that Mike has entrusted me with his legacy,” commented Joe, HEXA’s new Owner, President, and CEO. “HEXA has the hardest-working people and the best customers. It’s a privilege to take over ownership as we grow the company, do the work we love, and continue to make lasting friends along the way.”

In 2021, we watched our company grow — not only welcoming new clients and completing many great projects, but also expanding our team. We created positions, brought in additional experts, and focused on ways to make the HEXA family stronger and more cohesive.

To set a marker for continued growth and expansion, we started a new tradition in 2021; during our annual Christmas party, we give away a motorcycle to an employee who wins a raffle by having their name drawn from a hat. Each year, as we grow, so will the bike be bigger and better!

This year, Braulio Alvarez was super-excited to win a fun, Coleman 200cc minibike. With a top speed of about 20 mph, it’s great for zipping around the neighborhood or running errands. Braulio has been a valued part of the HEXA team for a little more than a year, working as a technician/laborer. Other employees also won fantastic items — a 65-inch Samsung TV, Yeti cooler, and gift cards. All HEXA staff members received Wyld Gear water bottles and cups. This new tradition celebrates what being part of HEXA is all about – the fun and camaraderie of working together as a solid team.

With a lot of projects already booked for 2022, we are fueled by the energy and excitement that comes with working in a positive environment, growing along with great people who are dedicated to the values on which this company is built, and serving customers who have also become cherished friends. We stand behind each other and have our customers’ backs in protecting their concrete investments. We anticipate great things and look forward to sharing more good news as the year unfolds. Stay tuned for 2022’s bigger, badder bike!

It has been just over a year-and-a-half since we celebrated our 20th anniversary and renamed our company to HEXA™ – A McDonald Company to mark the end of a successful 20 years and the beginning of a new phase in our growth. We chose the HEXA name and logo because:

  • Like the hexagon, it shows that we are stronger under pressure, delivering the highest quality solutions.
  • Like the strong community bond of bees within a hive, the hexagon-shaped cells of the hive represent our commitment to communicating and building solid relationships with our customers.

We’re the same great company, run by the same people, with the same values. As one of the most well-respected locally owned and operated concrete repair companies in Colorado, it’s no surprise that word gets out about why it’s great to work with, and for, HEXA!

We’re excited that over the last 18 months we’ve grown and added new team members. We welcome these highly experienced and skilled people to our team. They’ve been in the industry for decades and are eager to work for a fun and progressive company.

If you know of anyone with concrete repair expertise who shares our values of delivering honest, friendly, quality service every time and is looking for a positive, fun company, tell them to check out our job openings!

We are deeply grateful for our customers who put their trust in us to keep their concrete structures strong, resilient, and stable. We’d welcome the opportunity to get to know you better, help solve your concrete issues, and become a resource you can continue to trust. We look forward to serving you!

As you’ve probably seen in the news, the construction industry as a whole is experiencing a shortage of materials and supplies. We’d like to shed some light on the situation and how your future projects could be affected.

There are multiple reasons for these shortages including a record level of housing starts, raw material depletion, and the pandemic’s impact on both shipping and manufacturing.

We are working hard to stay informed about the availability of materials and to maintain adequate supplies on hand when possible. We are also doing everything we can to keep our prices competitive.

You can stay ahead of the curve by getting in touch now to let us know your expected needs for repairs and new projects so we can plan as far out as possible. If you are not sure of your needs, schedule a free inspection and we can help prioritize the urgent projects.

One thing that we’re sure of in all of this uncertainty, is our commitment to building strong relationships with our customers, a fast response to your needs, and getting your projects done on time according to our quality standards. We value your ongoing business and friendship. Please don’t hesitate to contact us if you have questions.

We’ve encountered some unexpected curves in the road lately but we’ve leaned into them and kept our focus on making the most of the ride. As is likely the case with you, too, we’re learning from our experiences, finding ways to adapt to changing circumstances, and keeping our eyes open for opportunities.

We’re reminded often of what is important. One of those for us – the people we do business with and work with every day. We’ve known many of you for years and are grateful to call you friends.

We’re seeing things start to open up again. Before buildings and parking structures get too busy, we’d like to help you make the most of what may still be a little downtime by coming by to do a complimentary inspection of your concrete surfaces. While there are fewer people using your buildings and fewer cars in your parking structures, we can easily inspect even areas that may soon be less accessible.

Now – during the warm, dry months of summer – is also a perfect time to consider waterproofing projects. We’re happy to drop by to discuss ways you can get ahead of the game and prevent future costly repairs of cracking, spalling and other damage caused by water, snow, and temperature changes.

We’ve been known for our solid, long-term concrete solutions in the Rocky Mountain Region for more than two decades. Our teams take pride in doing it right the first time, on schedule and on budget.

Contact us today and we’ll schedule a time to give your property a free inspection, help you prevent small problems from becoming big ones, and budget for the future. We’d also love to catch up on what you’ve been up to and how you’re doing – whether concrete-related or not. We can all use some support now and then and look forward to moving forward with you. We will all get by with a little help from our friends.

At a trade organization meeting, we learned about a situation where a local women’s shelter desperately needed concrete repair. We were more than happy to help with the project.

“In a time when many people are stepping up to support each other by finding needs and filling them, we feel privileged to donate our time, talent and resources,” said Joe Keller, President and COO of HEXA™- A McDonald Company.

Sacred Heart House of Denver helps homeless single women and single mothers regain self-sufficiency through transitional housing and education programs. However, recently they became in dire need of assistance themselves. Over the years, heavy garbage trucks and other usage had substantially damaged the entry way and trash collection areas at Sacred Heart House. The freeze-thaw cycles in Colorado had caused the damage to worsen over time and the conditions were no longer attractive or safe.

“Funding has been increasingly challenging. The City of Denver ended financial support and foundation grant money has been reduced. Sacred Heart House now relies on smaller awards from foundations, grants from churches, and support from loyal individual donors. The recent, unprecedented situation with which we are all dealing has made those challenges even greater,” explained Sacred Heart House of Denver’s Associate Director, Garrett Singer.


The HEXA team was quick to respond, removing the concrete in the entry way and trash areas. Then we installed an 8-inch thick slab that will better stand up to the usage those areas receive.


Mike McDonald, HEXA Founder & CEO, said, “It was an opportunity to repair more than concrete. We were honored to be able to help a group that does so much to change the lives of people in Denver who are struggling. Giving enriches the life of the giver as much as that of the recipient.”

Sacred Heart House still needs help in the form of:

  • Financial donations

Financial donations are matched up to a total of $35,000, now through May 2020. These can be made online or mailed to Sacred Heart House at 2844 Lawrence Street, Denver, CO 80205

We encourage everyone to take the opportunity to fill the needs you see, whether at Sacred Heart House or in your own neighborhood. We are all in this together and it’s an opportunity to give back and support each other as never before.
