As home inspectors, we spend plenty of time looking beneath the house. Here, we find the foundation to be absolutely crucial as it is the basis of your home’s structure. Foundational cracks and gaps can threaten the health and safety of your family through environmental toxin exposure, water leakage and structural degradation. Careful consideration is required to ensure your home is protected from the ground up.
The Four Common Foundation Types - An Overview
Common in homes built before the 1930s, these foundations consist of stones of various sizes bonded with cement. They require regular maintenance for stability. Monitor for shifting stones or eroding mortar. Seal cracks and repair parging as needed.
Concrete Block Foundations
Popular after the 1920s, these evolved from cinder blocks to more robust concrete masonry units. Look for cracks or bulging walls which may indicate structural issues.
Poured Concrete Foundations
Dominant from the 1990s onward, these foundations are either poured on-site or manufactured off-site. Both types offer excellent strength and water resistance. Watch for cracks or water leaks as these can be signs of significant problems.
Concrete Slab Foundations
Common in warmer areas, these simple foundations involve a large concrete slab that supports the house. They are cost-effective and suitable for locations where deep digging is impractical. Monitor for cracks and ensure embedded elements like plumbing are in good condition.
Understanding your foundation is essential for proper home maintenance and repair. Different types require specific care, such as repointing for rubble/stone foundations or crack prevention in concrete slabs.
Regardless of foundation type, regular inspections and maintenance are crucial. This includes checking for cracks, ensuring proper water management and inspecting the surrounding soil.
