This homeowner was worried about his step settling. He knew his HOA would want him to get it fixed sooner than later, and he was also worried about trip hazards. He did not like the eye sore and wanted to find the right company to help him. He called Thrasher and System Design Specialist, Jeremy Sund, came out to meet with him. After the inspection, Jeremy found there was poor soil compaction around the home, leading to settling in his front steps and sidewalk. This also caused voids, leaving little to no support for the concrete slabs. Jeremy proposed we use our PolyLevel and NexusPro to lift the settled areas, fill the voids, and seal all the cracks and joints to prevent water from causing more washout. The homeowner was so happy with the finished product, and appreciated our urgency to get this done for him. There is no doubt this homeowner is worrying no more about his front steps!

These homeowners recently purchased their home for their kids and grandkids to live in, however they had some concerns with the foundation and needed to get it fixed. After looking into companies that do foundation repair, they reached out to us for a free estimate.

We sent System Design Specialist Rob Griffin to inspect the home's foundation to determine what was causing the foundation concern. Rob found that the fireplace was pulling away from the house, creating a gap between the outside wall and the chimney. He also saw that the garage was sinking because of weak fill soil that could not hold the weight of these structures. After thoroughly understanding the problem, Rob talked to the homeowners about options to solve this, and they loved how he described the options, so they decided to move forward with us. Our team installed Push Piers to stabilize the home and they were able to fix the problem by leveling the chimney and home.

The homeowners were very happy with the quality of work the crew did on their home. Check out the leveled chimney and home!

This homeowner was looking to remodel his home, and he wanted to ensure that his floor was secure before he could fix anything else. He knew there was a gap between the flooring and the walls that the carpet was hiding, so he decided to give us a call for a free inspection.

We sent System Design Specialist Anthony Salcedo to inspect the issue and propose a comprehensive solution for this homeowner. Anthony noticed that the area of the home rested on a concrete slab, which had settled overtime, causing the gap between the floor and walls as well as the struggles with sticking doors. He proposed a solution that made the homeowner quite excited to continue with us. Anthony and his team utilized PolyLevel Concrete Leveling on the full area in the interior of the home. This would allow the home to return to its original level. 

The homeowner was extremely impressed with the finished project and now he can remodel his home without worry. Check out the raised concrete!

This homeowner didn't have any settled concrete problems, but when he saw his neighbor's huge settlement issue solved by us, he decided that he wanted to prevent his concrete from having the same problem. He researched solutions to prevent concrete settlement, and when he saw our solutions were long lasting, he gave us a call.

We sent System Design Specialist Anthony Salcedo to inspect the joints of this homeowner's driveway to determine what joints needed to be sealed the most in order to prevent concrete settlement. Anthony found that the expansion joint on the concrete as well as a few other smaller joints near the garage needed to be sealed properly in order to avoid this settlement problem. After discussing which concrete joints were the most troublesome for the homeowner, Anthony worked using NexusPro Sealant to seal off the troublesome joints in the concrete.

The homeowner was extremely happy with the installation and he was very happy with the communication leading up to and following his appointment. Check out his newly sealed concrete joints!

Job Stories From Aurora, CO
Front Step Repair in Aurora, CO

This homeowner was getting worried about the tripping hazard in front of his home. The steps have been sinking for a bit now, and he knew his HOA would want him to get it fixed. He wanted the right company for him to fix this, so he called Thrasher. System Design Specialist, Jeremy Sund, came out to meet him. Jeremy inspected the concrete, and found there was poor soil compaction. This was causing voids under the concrete, leaving almost no support for the slabs. This was what caused the slabs to start settling. Jeremy proposed we use our PolyLevel to lift and level the concrete back to place, and NexusPro to seal the cracks and joints to prevent water from causing any washout. The homeowner appreciated our urgency and enjoyed how great the job looked in the end. There is no doubt he is not worried anymore of any of his guests tripping. 

Heave Solution in Denver, CO

When a foundation or basement concrete slab is undermined, the heave solution can help. In this case, a water main blew at the top of the hill and undermined an entire foundation and it completely blew up the basement slab. It is fairly common for a concrete foundation or basement slab to sink or settle in this area because the soils in Denver have the tendency for extreme swelling due to bentonite. While builders are now designing foundations to avoid this damage, many homes still suffer from these settling and sinking problems.

The heave solution as used here includes the removal of the entire concrete slab as well as approximately 8 to 10 inches of soil also needing to be dug out. After this, we install miracle soil nails on a 6 foot grid, then lay down void form, and tie in number four rebar in the soil nails. The last step here is to repour a concrete slab so that if the soil heaves, there will be a gap between the structural slab, and the footings slab. 

This solution however is only for extreme cases when no other support structures can aid in the fixing of your home's foundation. Other suggestions to support the structure of homes in these situations include Carbon Armor Wall Reinforcing Strips or Piers to raise the foundation. If you are struggling with the heaving of your foundation slab, reach out for a free estimate!

Common Crawlspace Issues in Denver, CO

Crawlspaces are no stranger to the Denver area. While crawlspaces can be helpful for the structure of the home, if they are not properly sealed off from the earth, then the earth will find its way into your home. 

This crawlspace for example was not properly sealed off from the earth, which allowed dirty air and moisture to rise up through the crawlspace and into the home. When this air reached the home, mold started to grow, and the floor supports were weakened. Without encapsulation, this problem of not properly sealing off your crawlspace can hurt your home's structure, and the air that you breathe.

One way to solve this problem is to use a dehumidifier. A good dehumidifier will prevent mold from growing and decrease the amount of moisture in your home coming from your crawl space. Another solution would be to add additional supports to the flooring such as support jacks that would help to maintain the structure of the floor despite the weakened original supports. The best solution for this would be encapsulation to completely seal off your crawlspace from the rest of your home.

Make sure when you try these solutions, you get them done by a professional because many cheap attempts to improve your crawl space do not work for long. Use a professional who has the best solutions and gets the job done right.
