What Are Foundation Piers?
When Are Pier Foundations Used?
- If your property contains mostly decomposed rock near the surface.
- If your property contains a vast tree root system.
- If your property contains a lot of stiff and resistant clay.
- If your property has a low water-bearing capacity.
- If your home is built from logs or timber.
- If your home needs to be built on a slope.
Do Foundation Piers Really Work?
- Less material – Because piers are spaced out from each other, they require fewer materials to build.
- Wider design variety – There are multiple types of foundation piers used by home builders: concrete blocks, solid piers, and drilled caissons. Contractors can change or add to the design even after your foundation is built.
- Less excavation and disruption – Pier and beam foundations don’t require as much excavation as basements or slabs since contractors only need to build individual piers.
- Less water damage – Because foundation piers keep your home off the ground, rising water won’t be able to damage the wooden beams and joists.
- More visibility and access – Electricians, plumbers, and sewer line professionals have clear access to wires or pipes that run underneath your home. This also makes it easier for foundation repair specialists to inspect any damage to your home.
- Less vibration – Foundation piers transfer the weight of your home into the soil below it. This means that if there’s an earthquake, the piers will counter the movement.

Is It Cheaper To Build On A Slab Or Foundation Piers?
Slabs are cheaper to build but harder to maintain over time. Foundation piers offer more flexibility and accessibility, making them easier to care for as they age. Slab foundations typically cost homeowners between $5,000 and $20,000. Pier foundations cost homeowners between $16,000 and $30,000.
Things You Should Know About Foundation Piers
- Sagging – If some of your foundation piers sink into the soil deeper than others, your floors can begin to sag and creak.
- Tilting – If your foundation piers start tilting, you might notice some strange effects in your home, such as sticking windows and doors.
- Failure – If they’re poorly built and not well maintained, these piers can collapse or crack over time.
- Exposure – Because the underside of your home is exposed, moisture and humidity can affect your piers, beams, and joists. In order to counter this, experts need to encapsulate and insulate your crawl space. Without proper insulation, your foundation could even be energy-inefficient.
