Foundation Cracks in the Bay Area


Any sort of foundation crack is a bad sign. However, the size and shape of the crack may indicate a different cause of foundation failure in your home. It is important to know what caused the foundation problem in order to determine the best solution. Fortunately, the expert foundation repair team at Bay Area Underpinning can examine cracks in your foundation and find the best repair options.

Large, deep foundation cracks are an obvious problem – these cracks might indicate that the home is no longer structurally sound. However, even small foundation cracks should be repaired as soon as possible. Foundation cracks, even small ones, may allow water, debris, or pests an entry point into your home. Keeping your home safe and sealed requires fixing foundation cracks as soon as you notice them, no matter how small and insignificant they might seem to you at first.

Fortunately, we have a range of different crack repair options for foundation cracks in your home. We offer solutions such as epoxy crack injection; foundation piers – push piers, resistance piers, helical piers, slab piers, concrete piers; and carbon fiber repair. Contact our professional team to find out which solution best fits your home and budget.

Types of Foundation Cracks and Repair Solutions

There are several different kinds of foundation cracks that you might find in your home. Here is a breakdown of different cracks and what they might mean for your California home:

  • Vertical Cracks: These cracks run up and down the foundation walls or sides. Vertical cracks are quite normal in most foundations and are not necessarily a sign of structural danger. Very wide vertical cracks may be a result of hydrostatic pressure from excess moisture in the soil pushing on the foundation. If this is the case, carbon fiber repair may help straighten basement walls. Otherwise, small cracks can be filled with an epoxy crack injection to prevent leakage.


  • Diagonal Cracks: This kind of crack is normally caused by differential foundation settlement. If the settlement is severe enough, piers can be installed to lift the settled part of the foundation. For slab-on-grade piers, slab piers are best, while helical piers or resistance piers work well for other types of foundations.
  • Horizontal Cracks: These are the most serious kinds of cracks. Cracks that are running sideways in your foundation indicate soil pressure due to temperature fluctuations or hydrostatic pressure. Excess moisture in the soil can push on the foundation walls, causing horizontal cracks. If the water in the soil freezes, it can also put pressure on the foundation walls, leading to cracks running horizontally. These kinds of cracks are best fixed with carbon fiber repair methods, which help stabilize and straighten bowing and cracked foundation walls.
  • Stair-Step Cracks: If the cracks in your home’s foundation are stair-step shaped, they are most likely the result of foundation sinking and settlement. If these cracks do not go through the foundation, they may be minor and fixed with injection techniques. However, if the foundation is cracked all the way through, a more involved solution such as pier installation may be required. Be sure to have these cracks looked at by a professional.
