Types of Structural Repairs

When it comes to effective, long-term foundation repairs andstructural repairs, it’s always best to trust the professionals. Notonly willyour local foundation repair expertsbe able to assess the issues found present within your home, they’llbe prepared to discuss the types of repairs that may be needed in detail and ensure that they are performed flawlessly. Somecommon repairs required to address issues from the above list of signs and symptoms include:

  • Epoxy Crack Repairs: A great option for repairing cracks in concrete slabs, as this method involves injecting a high-strength epoxy compound into the cracks to bond and seal the severed areas.
  • Epoxy Stitch Welding: Another common repair for cracks in concrete slabs, this method provides additional reinforcement along the cracks through injecting high-strength epoxy material along with carbon fiber strips or staples.
  • Carbon Fiber Reinforcement: This is an effective measure of repair for basem*nt walls that are bowing inward or have horizontal cracking. The carbon fiber reinforcement straps are applied directly to the wall and provide the reinforcement and stabilization needed, resulting in a fast and cost-effective solution.
  • Polyurethane Foam Injections: A type of pressure grouting procedure that utilizes high-strength, hydro-insensitive structural polymer foam, this method is typically used for concrete slabs and concrete floors that are sloping, unlevel, or uneven. By injecting polyurethane foam into holes drilled through the concrete slab, it’s possible to fill voids between the bottom of the slab and the top of the soil beneath it (or consolidate loose and soft soils) to create a more solid base for the slab—preventing further movement in the future.
  • Helical Piles: For leaning chimneys or for setting foundations, theinstallation of helical piles is typically the most effective and most ideal solution. Helical piles are also commonly used to repair concrete slabs,as the helical piers are paired with slab bracketsto transfer the weight of the concrete from the base ofthe slab to a more suitable, load-bearing location in the soil.
