Contributing factors can include: - Age and original quality of concrete or masonry - Lack of water management or water intrusion - Absence of reinforcing steel (rebar) - Long‑term moisture exposure due to poor drainage - Deterioration that may be hidden by skim coats on interior or exterior walls Simple Ways to Check an Old Foundation Homeowners can look for these signs of significant decay: - Hollow sound when tapped: Lightly tapping several areas of foundation walls and hearing a hollow sound can indicate problems below the surface. - Soft or crumbly material: If you can dig into the concrete or bricks with something as simple as a butter knife, this is a strong indicator of serious deterioration. - Core sampling: When issues are suspected but not obvious, a core sample can be taken and sent for external testing to provide an accurate analysis. What Not to Do Certain common approaches can actually compromise an older foundation: - Digging continuous trenches alongside the base of interior foundation walls - Digging down for additional basement height without proper engineering - Installing interior drainage or removing the basement slab in ways that undermine the existing foundation These actions can lead to horizontal cracking, foundation failure, and serious impacts on the home's stability and livability. Foundation Replacement: Is It Right for Your Home? When considering a full foundation replacement, some key questions include: - How long will you or your family keep the home? - Do you want to create more living or working space? (for example an ADU, ground‑floor apartment, studio, or workspace) - Are there existing structural concerns or seismic risks with the current foundation? - Are water intrusion or rodent problems an ongoing issue? Space Down Under focuses on full foundation replacement and new foundations; they do not work on, save, or retrofit older foundations. Frequently Asked Questions Do I need to remove furniture before my house is lifted? Generally, furniture and household items can remain in place. Large or unusually heavy collections (for example, extensive libraries, large record collections, or pallets of materials stored inside the home) may need special attention before lifting. Can I live in my home while the foundation is being replaced? No. Temporary alternative living arrangements are required while the house is shored and work is underway. How long does a typical foundation replacement take? A full foundation replacement usually takes a minimum of 3–4 months, depending on project scope and conditions. Can you retrofit or partially replace my old foundation (for example, just one wall)? No. Space Down Under does not retrofit or attempt to save older foundations; their focus is on full replacement and new foundation systems. A sound foundation is the structural base for what is often a family's largest asset; decisions about assessment and replacement should be made carefully with professional input.
