How to Repair Cracked Foundation
Foundation cracks can indicate a serious issue. Professional repair service should be hired based on the nature and size of the crack.
Before you attempt to fill a crack in, make sure it is free of dirt, dust from concrete or old crack sealant. Sweep, or vacuum, any debris that remains.
Repairing Non-Structural Cracks
There are two types: structural and non-structural. Non-structural Foundation Cracks are caused by concrete shrinkage and soil movement. They can also be caused by aging.
Horizontal cracks could indicate serious problems. If your soil around your foundation walls is not graded properly and drained, it could create hydrostatic force that exceeds its weight-bearing capability, causing walls to crack, bow, or crumble.
Underpinning your foundation with concrete piers drilled into the ground or helical piers will help to repair horizontal foundations cracks. As a measure to stabilize a bowing foundation, you can use steel I-beams or carbon fibre wall straps. As well as fixing these issues, your contractor can regrade the yard so that it slopes away. This will give you added peace ofmind.
Repairing Structural Cracks
Cracks wider than a 1/10 inch could indicate structural damage. A professional should conduct a thorough assessment if cracks widen or if other symptoms occur, such as wall bowing.
Cracked soil can be caused from a number of things, including concrete shrinkage, soil shifts, and water pressure fluctuations. But horizontal, diagonal, and vertical foundations cracks are usually a sign of foundation shifting. Professional repairs are needed.
Before you begin any crack repair, ensure that the area in question has been dried. Scrub the cracks with a shop vacuum and wire brush to remove loose concrete and dirt. If there is water, you can use urethane.
When cracks occur in conjunction with structural issues that require foundation contractors to fix, they can use hydraulic jacks to lift the foundation into place. Further, epoxy or carbon fiber wall straps can be used to reinforce the foundation. It can also be modified in terms of how water flows.
Sealing Structural Cracks
When foundation cracks are discovered, they must be professionally assessed to determine their cause and repaired quickly to avoid air or water infiltration. Even if a foundation crack does present structural concerns, it should still be repaired promptly to prevent water and air infiltration as well as other potential problems.
The cracks that are not structural usually occur due to concrete shrinkage. Although they do not pose a threat to the home's structure immediately, if these cracks widen they could indicate a more serious problem.
To seal cracks in the concrete, first clean up the area by removing any debris such as loose dirt or leaves with a blower and wire brush. To avoid contamination, mix two sticks of equal parts epoxy crack sealer and scrub each crack. Apply the sealer along the length of each cracked.
Repairing Vertical Cracks
If a vertical foundation crack is less than 1 inch wide, this may be the result of concrete shrinkage. This does not pose a threat to your home's structural integrity. A professional can seal cracks with a urethane kit or cement-latex mixture. If cracks become wider, they may signal more serious structural problems requiring repair.
In order to prevent cracks from worsening with time, slabs that have settled and cracked should be addressed as soon possible. You can correct this issue by using helical pilings, concrete piers drilled into the ground, or pushing piers.
Before beginning any foundation repairs, your technician cleans cracked surfaces to ensure that resin injection penetrates into all cracks. If dust or debris is present, it could interfere with the bonding process. In order to prevent this from happening, holes are drilled either side of any cracks.
