Driveway and Front Walkway Repair in Centennial, CO

Driveway and Front Walkway Repair in Centennial, CO Driveway and Front Walkway Repair in Centennial, CO

This homeowner wanted to fix the dip they around the entrance of their garage as well as the dipping front walkway. He was worried that the rest of his concrete would eventually face the same fate of settling, do he knew that he needed to act sooner rather than later. When he found the detailed process of concrete repair to be too much to do on his own, he decided to give us a call to see how we could help lift his concrete burden.

We sent System Design Specialist Jeremy Sund to inspect the homeowner's driveway and front walkway, diagnose the issues facing these, then design a solution fit to fix and protect the concrete surfaces from further damage. Jeremy found that the soil underneath the homeowner's driveway and front walkway was poorly compacted, meaning that the soil was vulnerable to wash out and settlement. He suggested that we utilize our 3-part Concrete Protection System to fix, protect, and prevent further damage to the concrete surfaces, and the homeowner was very excited with this plan.

One of our installation teams came out to the home and started to utilize the 3-Part Concrete Protection System, including PolyLevel Foam to lift the concrete, NexusPro Sealant to seal the cracks and joints of the concrete, and SealantPro to protect the concrete from further damage. The homeowner was extremely happy with these solutions and he noticed that there was no longer a bump as he pulled into his driveway. Check out the before and after of the front walkway!

This family had lived here for several years and noticed their porch was getting worse and worse over time. They knew this issue would not fix itself, they started their research. They had a few bad experiences with contractors, but trusted our experience when they read the reviews. Anthony Salcedo, System Design Specialist, came out to meet with them. He did his inspection, and found that due to an abundant amount of moisture from bad drainage, the soil under the slab shifted. This caused the slab to start sinking and cracking. Anthony went to the family with these findings, and came up with a solution. We used Polylevel to lift and level the slab back into place, and NexusPro to seal the joints and cracks. These products are waterproof, so they will prevent any more washout in the future. The family is very happy with the outcome, and we know they have the peace of mind they deserve.

This rental property owner needed to secure the foundation of the building he bought so that he could rent out the units. He looked into foundation repair companies in the Denver area, as he didn't know much about the area because he lived out of state, he came across our services and he gave us a call.

We sent System Design Specialist Anthony Salcedo to inspect the rental property's foundation and determine what would be best to help solve the foundation issues. When Anthony arrived, he was shocked at the amount of wall damage that had occurred. Anthony found that all of the walls had some degree of failure and lateral movement; Two of the walls were scoped out for full replacement because of how severe their degree failure was. After the thorough inspection, Anthony gave the homeowner a call to discuss what damage had occurred as well as what solutions we could offer to fix this problem. The rental property owner thought these solutions seemed the most thorough of all the solutions he had heard, so he decided to have our team fixed his foundation wall problems.

One of our installation teams went to fix the wall problems in the home shortly after the homeowner moved forward with our services. The team utilized GeoLock Earth Anchors on the two walls with less degrees of damage. After an engineer report surfaced from the rental property owner, our team was able to accommodate the other two severely failing walls by installing our EverBrace Wall System which acts as a new wall for stabilizing the property. The report also stated that new support posts were needed in the center support beam to have proper support, so our team also installed SmartJacks to stabilize the center support beam. 

After all this work was complete, the rental property owner was very relieved that he could start renovations for the rental properties to be rented out. Although this project was tough, our team was able to stabilize all of the walls and give the rental property owner a chance to renovate his property. Check out the wall transformation in this rental property!

Foundation Push Piers in Lakewood, CO

Steve is living in his forever home and he wanted to make sure nothing would ever get worse. He knew of Thrasher and our reputation, so he gave us a call. System Design Specialist, Anthony Salcedo, came out to meet with him. Anthony did his inspection and found the soil underneath his foundation was causing the front side of his house to sink into the Earth. The sinking was causing multiple cracks in the living space upstairs. There was also movement in his driveway due to the same bad soil in the area. To fix this issue, Anthony proposed we install Push Piers on the foundation to properly stabilize. He also proposed we use PolyLevel and NexusPro in his garage and driveway to lift, level, and stabilize the slabs, as well as seal the joints and cracks. Steve loved this solution, so we sent out our installation team. There is no doubt he is worrying anymore about his forever home.

There is no doubt that the family does not have to worry about their concrete anymore! 

Front Porch Repair in Centennial, CO

This family has been living here for a while. They noticed their front porch getting worse and worse over the years and were done dealing with it. They knew it was a problem that was not going to fix itself, so they started their research. Thrasher came up on the first google search, and they trusted our experience and processes after reading the reviews. Anthony Salcedo, System Design Specialist, came out to meet with them. He did his inspection, and found the soil under the slab was shifting due to an abundant amount of moisture caused by bad drainage. He went back to the family with these findings and a solution. We fixed this porch slab by using our Polylevel to lift and level and stabilize back into place. We also used our NexusPro to seal the joints and cracks. No only did this fix the slab that was sinking, but also saved the pillars and remaining stoop. They were so happy with the finished product, and we know they have the peace of mind they deserve! 

Foundation Repair in Littleton, CO

Our customers in Littleton, CO had purchased their home over 10 years ago, and had problems with the floor and foundation of their house since the day they had moved in. This couple now with twins on the way wanted to solve their problem so their family could safely enjoy the basement space. They were pleased with the solutions our crew offered and how we could fully address their problems and concerns about their home. 


Our crew determined that the soil under their basement floor was causing the floor to move up, and could cause major problems to the foundation of their home. We solved the problem by installing our SmartJack and Helical Piers systems to give support to the walls and ensure the floor can not move up or down causing structural issues. 

Foundation Repair in Littleton, CO

These homeowners were looking to sell their home, but knew they had some foundation concerns. They knew of Thrasher's reputation, and gave us a call. Anthony Salcedo, System Design Specialist, came out to meet them. After doing the inspection, Anthony found the way they built the foundation of the home was too heady for the small amount of base they designed for the load. This base is a caisson base that is to prevent heave. This did prevent heaving, but there was not enough support to prevent it from sinking. There was a few inch drop from one side to the other. They had a few bids out, and we were the ones that were able to diagnose it correctly, showing them what the house was doing and why our solution was the best possible solution to fix the problem. Anthony proposed a full perimeter push piers, as well as smart to support the loadbearing beam in the middle of the home. This can help lift the home back into place. The homeowners were glad we had the patience and practice of going over this design with them until they understood the why behind everything. The were happy with the entire process, and had a great experience with the crews. There is no doubt they are ready to sell this property!
