Recently, Helical Pile World put a case study of ours in their newsletter. We had a homeowner in Fullerton, CA give us a call about wall and ceiling cracks in a specific area of their home as well as gaps in their interior walls. One wall had settled so much you could see from one room into the next through the gap it made! They had tried [...]
Our production team installed ten push piers along the entire back wall of the home which had a measured elevation drop of close to three inches. Following the installation of the push piers, our production team entered the crawl space and installed 10 new posts and pads to provide support the home’s girder beams and subflooring. After clean up, Mr. G performed a site walk with one of our foremen and was extremely pleased with the work that was performed. Not only were there no signs of the 10 push piers we installed, but Mr. G will not have to worry about the expansive soils below his home now that the home’s weight had been transferred to our push piers.
JOB COMPLETED FOR BRENT THUNSTROM Completion date: November 11, 2015 Location: Murrieta, CA WHY DID THE CUSTOMER CONTACT US? This home was purchased as is by the homeowner. The home needed several repairs. The homeowner saw many signs of foundation failure throughout the home including doors and windows not opening properly. The homeowner contacted Dalinghaus Construction to repair the homes foundation. SOLUTIONS PROVIDED: Dalinghaus Construction, was able [...]
Using polyurethane injections our team was able to seal the leaks and voids that grout injecting could not repair prior to our arrival. We injected 342 sq/ft of our hydrophobic, expansive polyurethane through 5/8” holes at a rate necessary to not only fill the voids but also ensure each of the cracks and leaks were sealed. This ensured a nice dry environment for the basement to be built on.
Our knowledgeable Project Consultant performed an inspection of Ms. Turner’s property and found no measurable differential in the floor’s elevation. With no signs of foundational settlement, the cracks were caused by either a bad concrete pour or a lack of rebar support. Ms. Turner only wanted to address repairing the cracks so that she could get her new floors installed. Our Project Consultant proposed repairing the cracks with carbon fiber staples, in which perpendicular saw cuts would be installed every 18 inches along the crack. After the staples are installed into the perpendicular cuts, a two-part epoxy would be injected to cover the staples and fill the crack. Once Ms. Turner was ready to move forward, the production crew performed the repairs on all seven cracks and she was extremely pleased with the results. The crack repairs did not put a delay on her remodeling project and she was able to keep her wood floor installation as scheduled.
At the end of the inspection, our Project Consultant put together a repair plan and proposal for Mr. Frazier. The repair plan consisted of eight push piers to attempt to raise the home, raising and shimming of current post and pads after lifting the home, and a geotechnical engineering recommendation to test the soils below the home. Once Mr. Frazier received a second proposal, he decided to move forward with Dalinghaus Construction’s repair plan and get the project scheduled. Our production team spent the first day digging and prepping the push pier locations, and the second day was spent installing the push pier brackets to the foundation’s footing along with hydraulically driving the galvanized steel piers to load-bearing strata. The third, and final, day was used to lift the house off of the steel piers that were previously driven into the soil below the foundation and adjusting the home’s posts and pads once the crew lifted the home to a maximum practical recovery. Not only was our crew able to lift the home close to its original elevation, but Mr. Frazier will no longer need to worry about that area of his home settling with the home’s weight being transferred to the newly installed steel push piers.
Dalinghaus Construction’s Project Consultant created a repair plan and proposal for Mr. Taylor while at the inspection. The repair plan consisted of five steel push piers along the wall near his living room and polyurethane injections to fill the voids. With the foundation measuring 2.2 inches of settling, our production crew started with excavating the push pier locations and cleaning up the exposed footings. Once the footing was cleaned up, the pier brackets were put into place using steel wedge anchors, and the galvanized steel piers were then ready to be hydraulically driven down against the weight of the foundation. Our production crew drives the push piers to load bearing strat, which is often bedrock, but they hit load bearing strata between 30 and 50 feet at each of the five pier locations at Mr. Taylor’s home. Once the piers were driven the home was lifted to maximum practical recovery, and the polyurethane was injected to fill the void created between the foundation’s slab and the soils below it. Zach was thrilled with the outcome and happy that he would no longer have to worry about damages caused to his home from the expansive soils it rests on.
One of our knowledgeable Project Consultants performed an inspection and found that the home had in fact settled over an inch and a half. His repair plan consisted of installing 5 new push piers, excavating and lifting the 9 existing push piers, and inject polyurethane to fill the void that would be created when the home is lifted. Upon excavation, our production crew found that the old push piers were not driven to load-bearing stratum and were therefore not supporting the foundation from the expansive soils below it. Our crew excavated each of the old push piers and prepared them for re-lifting. They then prepped the five new push pier locations and got to work installing the new hardware. Once the new push piers were in place the crew was able to drive them to the correct depths and lift the home.
With Mr. Voss already having the engineers perform their inspections, Dalinghaus Construction was able to develop a repair plan and proposal using the engineer’s measurements and recommendations. Our production crew installed five helical piers, along with some concrete removal and replacement at the helical locations. The project was completed in two days, and after completion, there were no signs that our team had been working on the home. With the installation of the five helical piers, Mr. Voss would no longer need to worry about the expansive soils below his foundation. The weight of the home, in the area where work was performed, was transferred from the soil directly to the helical piers. When the soil expands or contracts in the future it will no longer affect one of Mr. Voss’ most valuable investments.
We made the homeowners aware of the current foundation issues and offered to add foundation repairs to the scope of work, and suggested that before adding new flooring to the home that the foundation issues be addressed. The homeowners decided that fixing the issues of the foundation would be the best option so that they would not have issues with the new flooring in the future. Dalinghaus Construction, repaired the foundation, by adding piers as well as new posts and beams in the crawlspace area of the home to lift and stabilize the home from future foundation settlement. Once the foundation repairs were complete the home was remodeled, new flooring was installed as well as new kitchen cabinets and countertops. The homeowners were very pleased with the work completed by our crews and happy to know that their home is now safe from future soil settlement.
