The HEXA team has decades of experience, and we pride ourselves on staying current on the most innovative and cost-effective ways to keep your concrete working for you. Our team is currently tackling a complex and interesting project – reinforcing two concrete columns at the main entrance of an older apartment building in Denver to extend their longevity.

These columns are structural, running six feet above and three feet below the surface concrete, so their weight-bearing capability is critical to the building. To ensure that they can continue to do their job, we are strengthening these columns by pouring concrete then adding a carbon fiber wrap to further reinforce the columns.

Fiber-reinforced wraps can be up to ten times stronger than steel, yet thinner and flexible to help increase the load-bearing capacity of concrete. Shoring up the columns is a complex, multi-step process. The project is rewarding because by extending the life of the columns, we are extending the life of the building itself.

Call us to schedule a free inspection or if you suspect you need repairs. Addressing those needs now will save you money down the road.

Just another day at the office for HEXA. We wanted to share with you our beautiful view as we are busy inspecting winter and sun damage to window sealants. This is a common issue we’re seeing a lot of these days. If not addressed, it can allow water and chemicals in, which could eventually lead to structural damage and the need for major repairs.

Constant exposure to the elements can lead to sealant failure. No one likes a leaky building. Don’t get stuck with an average fix that leads to future complaints. At HEXA, we’re sealant specialists. We assess windows and use the proper sealants to wet seal any window perimeters that are leaking or will be in the near future.

Exterior repair locations can be difficult to access, but with our expert team and know-how, nothing is out of reach!

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.

The really cold snap we recently experienced in the Front Range area was a rude reminder of how brutal winter can be – especially to concrete.

Cold weather damage comes from more than low temps. Concrete is vulnerable to salt, gravel, magnesium chloride and other ice-melting chemicals. Salt can leach through concrete and rust reinforcing rebar and wire mesh, adding to the corrosion that occurs when water seeps through cracks that expand and contract with the freeze/thaw cycle. If concrete is not properly sealed or the sealant is damaged or worn, seepage is an even greater risk and can eventually do damage to supports and other structures below the concrete.

Snowplows stress concrete as well. Especially those that do not use rubber blades can damage coatings. They can also cause damage to expansion joints. Even studded snow tires on passenger vehicles can take a toll, especially at exceptionally low temps when concrete is more dry, brittle, and susceptible to damage.

You can’t stop the cold, but you can repair the damage and prevent it from getting worse. We’ve been maintaining and repairing concrete in Colorado’s Front Range for more than two decades and are experts at dealing with whatever winter throws at it!

Give us a call to schedule a free inspection to assess winter damage to your concrete. We’ll help you plan and budget for repairs and preventive maintenance that will help your concrete stand up to Colorado winters.

Why are our crew members dragging a chain across a concrete surface and striking it with a hammer? We’re checking for delamination, which may be hidden and often can be “heard” before it is seen.

Typically, when metal strikes solid concrete, it produces a clear, ringing sound. But if a dull, drum-like thud or loud clack is heard, there are likely hollow areas in the layers of concrete. Dragging a chain across concrete surfaces and listening for a change in tone helps us find extensive damage that has occurred below the surface due to water intrusion, which can damage the rebar and cause delamination. Striking the concrete with a hammer helps further pinpoint these voids.

Delamination occurs when thin layers of the slab, typically 1/8 to 1/4 inch thick, separate from the base concrete of a finished slab. This problem often occurs if finishing operations start prematurely and close or seal the surface before excess air and water can bleed out of newly poured concrete, creating subsurface voids where air or water was trapped. These voids create weakened zones right below the surface that can eventually detach under use, especially if your concrete is exposed to heavy traffic or wheel loads.

It is important to address signs of delamination early to avoid extensive repairs such as removing and resurfacing the top layers of concrete. Schedule now for an early spring appointment to have your concrete inspected for delamination and other hidden, or not-so-hidden, signs of damage so that you can take preventive action before they become costly repairs.

Winter is coming to Colorado and it’s a tough season for concrete. Water seeps into joints and existing cracks, expanding and contracting with the freeze/thaw cycle, which further damages the concrete. Taking preventive action before the long months of winter can ensure that your vulnerable concrete will have sustained less wear come spring.

In this short video, the HEXA crew is scraping away the existing coating and sealants on the island areas of a parking structure. The islands were weathered, which had allowed water to seep in and had started breaking down the concrete. Once the old finish was removed, we installed new urethane sealants, a cementitious coating, and a clear, penetrating sealer. Had we not addressed these issues additional water could have intruded, potentially deteriorating the parking structure underneath.

By being observant of the condition of their concrete and taking proactive steps when they suspected damage, the client has protected themselves from future repairs, expense, and possible liability.

Our free inspection can help you do the same — give us a call today!

HEXA is working hard to make your properties work better for you! Our expert crews recently made some repairs and installed a new pedestrian coating on five balconies at a property in Denver. This short video shows some of the work.

Concrete damage is common in Colorado. It occurs when water intrudes into concrete joints and cracks then freezes and expands, which can cause the existing coating to fail. For this project, water began leaking into the interior of the building due to the compromised coating. The fixes included removing the deteriorated coating, repairing and replacing the damaged concrete, and then installing a brand-new pedestrian coating for a final seal and finish.

Had these issues not been addressed, water would have continued to leak into the building, creating damage to the interior and the need for costly repairs. You can stay ahead of potential damage and unnecessary expense! Watch for evidence of concrete spalling – round or oval depressions on surfaces or along joints, damaged ceiling tiles, and leaking around interior windows.

We offer complimentary inspections of your concrete. We’ll help you identify issues and allow you to plan for preventive maintenance or repairs before winter weather takes a bigger toll – not only on your concrete but on your wallet. Give us a call today to get on the schedule!

We’re staying busy and getting things done, including sprucing up buildings and parking garages. Here is a quick video clip of our crew having fun applying a shiny, new, garage floor coating in downtown Denver.

“HEXA did an exceptional job for us with our parking garage coating. They met our schedule, performance and cleanliness was impeccable, followed through with all inspections, stayed within the proposed cost and daily communication was the best.  This project rates at the very top of my list of most professional projects ever – thanks to HEXA.” – Pamela Coburn, Property Manager, Cornerstone Partners, LLC.

We appreciate Pamela’s kind comments because we love what we do and always want to be at the top of your list.

Hope you have a great day too!

We regularly hear from our customers that we make their jobs easier. It’s something that HEXA™ – A McDonald Company sets out to do every day through our great people, quality work, and superior communication.

That third element, superior communication, is what truly sets us apart, and no other concrete repair contractor in the Rocky Mountain region comes close to our cutting-edge communication. Here’s how it works.

Over 20 years in the concrete repair business in Colorado, we have honed a reporting system to keep owners and managers up-to-date on the status of their project every step of the way. HEXA customers receive progress reports that are emailed daily, giving you a well-organized overview of the project status, along with important details including:

  • The number of crew members working on your project
  • Morning and afternoon ambient and surface temperatures
  • Photos of work in progress/work completed
  • Quantification of work that has been completed
  • What’s scheduled next

These reports have proven essential to engineering teams’ project files and keep owners and managers fully informed about project status – all without having to set foot on the property. It’s also an invaluable resource for owners or managers who are not in the same locale as the project.

Here’s what our customers say: “HEXA (formerly McDonald Waterproofing and Restoration) delivers consistent quality and great communications. And with their daily E-reports, you always know where a project is, and that makes my job so much easier.” – Patrick Jaschek, EIT

That’s what makes us different. Your success is our priority. We’d love to hear from you, and welcome your thoughts and ideas about how we can serve you. Give our team a call at 303-279-8700 and we’ll be happy to come out and provide an estimate for getting the job done right.

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.
