    Permanent Wall Stabilization with EverBrace™ System

    We were recently called to a home where the block foundation wall was bowing inward, and severe water intrusion was a major concern. With the neighboring house so close, excavation from the outside was nearly impossible. Our team offered a quick, affordable solution: we installed the EverBrace™ Foundation Wall System from Supportworks, which permanently stabilizes even the most compromised walls. To address the water issue, we also added an interior waterproofing system, ensuring the foundation is protected for the long term. The entire project was completed in less than a week, with minimal disruption to the customer's home!

    A Garage on the Move: A Unique Approach to Foundation Repair

    When it comes to foundation issues, we've seen it all-and we've used some pretty creative methods to explain problems to homeowners. Recently, one of our Groundhogs™️ crews visited a home where the customer had noticed that half of his garage was sinking. The garage floor was noticeably sloping, and cracks were forming in the walls, signaling that the foundation had settled significantly. As we took measurements, we came up with a lighthearted way to explain the severity of the issue to the homeowner: "Your garage has sunk the equivalent of 8 dill pickle crispers over every 4 feet!" The customer got a kick out of that, and it helped turn a serious situation into a more relatable one. Humor aside, the issue was clear-unstable soil beneath the garage had washed away, causing the foundation to lose its bearing capacity. ### The Solution: Pier Installation To fix the problem, our team installed a series of piers along the side of the garage where the settlement was most severe. These piers were driven deep into stable soil beneath the washed-out layers, allowing us to lift the garage back to its original, level position. The piers provide long-term stability by bypassing the unstable upper layers and anchoring the foundation to solid ground below. ### Restoring Stability Once the piers were in place, we carefully lifted the foundation back to its original height, completely leveling the garage. The homeowner was relieved to see his garage returned to its former state, with no more sloping floors or structural cracks. More importantly, the pier system we installed will prevent future sinking, giving the homeowner peace of mind that his garage-and the rest of his home-will remain stable for years to come. ### Why Groundhogs™️? Foundation problems can be serious, but that doesn't mean the process of fixing them has to be stressful. At Groundhogs™️, we combine expertise with a customer-first approach, making sure homeowners feel informed and comfortable throughout the entire repair process.
