Block and base foundations, often found in older homes, have their unique set of challenges. Despite their durability and the ease of access they offer for repairs, they are not immune to failure. Understanding the causes of block and base foundation failure is essential for maintaining the integrity of your home. DuraTech Texas would like to highlight the primary causes, signs of trouble, and the effective methods to address these issues, ensuring your foundation remains solid and secure.
Primary Causes of Block & Base Foundation Failure
The most common cause of block and base foundation failure is drought. Extended periods of dry weather can cause the soil beneath the foundation to shrink away, leading to a loss of support for the blocks and beams. This can result in uneven settling and significant structural damage over time. Conversely, too much moisture can also spell trouble for block and base foundations. Heavy rains can erode the base of the foundation, allowing water to seep underneath. This can cause the soil to expand, lifting the blocks, which then drop back down as the soil dries, leading to instability and damage.
Signs of Block & Base Foundation Problems
• Instability in Floors: If your floors feel unsteady or you notice humps and dips, it could indicate foundation issues.
• Sticking Doors and Windows: Difficulty in opening or closing doors and windows can be a sign of shifting in the foundation.
• Separating Baseboards: Baseboards that pull away from the walls are often a symptom of foundation movement.
• Cracks in Sheetrock: Visible cracks in walls or ceilings are a clear indication of potential foundation problems and should prompt immediate action.
Methods of Block & Base Foundation Repair
• Readjustment: To correct unsupported beams and resulting floor humps, reducing the distance between the bases can help stabilize the structure.
• Reshimming: Leveling each base that supports the home’s wooden beams can address minor adjustments needed due to shifting or settling.
• Wood Replacement: Damage from pests or water can compromise the integrity of wooden supports and subfloor material. Replacing these damaged elements is essential to restore stability.
• House Leveling: In cases where the crawlspace is too narrow (less than 16 inches), lifting the entire house with airbags to increase crawlspace height can provide the needed room for adequate repairs and adjustments.
• Shaker Sill Installation: If the beams are too far apart, adding extra support with 4”x6” pieces of wood can strengthen the foundation and eliminate floor squeaks by distributing the load more evenly.
Preventive Foundation Measures
Addressing the causes of block and base foundation failure requires a proactive approach. Here are some preventive measures to consider. Ensuring gutters, downspouts, and grading direct water away from your home to prevent erosion and water seepage under the foundation. During drought, use soaker hoses to maintain a consistent moisture level around your home’s foundation to prevent soil shrinkage. Conduct bi-annual inspections of your foundation and crawlspace to catch and address issues early.
