House Raising and Jacking

House Raising

House raising (a.k.a house elevating and house jacking) is the process of house raising and building a new, or extending the existing, foundation below it. During the house raising (elevation) process most houses are separated from their foundations, raised with hydraulic jacks, and held by temporary supports while a new or extended foundation is constructed below.

There are many reasons people choose to raise their homes. Some of them the most common reasons is flood protection, to reduce flood insurance rates and/or to add more space to their home. Jump to Reasons to raise your house for more.

House raising: Reasons to raise your house

If you were a hurricane victim

If your house was flooded by Hurricane Sandy or Irene and you’d like to prevent it from happening again, you should consider house raising and raise your house above the Base Flood Elevation. The BFE is the computed elevation to which floodwater is anticipated to rise during a base flood and is a regulatory requirement for the elevation or flood proofing of structures. Once a structure is raised, only the foundation remains exposed to flooding while the living area is safe from damage.

If your home is in a flood zone

Whether or not you were a victim of the storm, House Raising in Flood Zonesif your home is in a flood zone, you should raise your house to protect it from future flooding. These zones are shown on flood maps. Moderate to low risk areas are zones that begin with the letters “B,” “C” or “X” and high-risk zones start with the letters “A” or “V.” To read the definition for each zone, click here.

The most vulnerable homes are in the “V” zones, which are waterfront areas that are at highest risk for flooding and subject to 3-foot breaking waves. But houses still need to be raised in the coastal “A” zones, which isn’t as vulnerable as the “V” zone but is still subject to major damage.

Even houses in “B,” “C,” or “X” zones should consider house raising. Roughly 25% of all flood insurance claims are filed in low to moderate flood-risk areas.

To lower your flood insurance

House raising will also lower your flood insurance in the long-run. Under the Flood Insurance Reform Act of 2012, you could save more than $90,000 over 10 years if you raise your house 3 feet above the Base Flood Elevation.

To add more space

House raising also adds more usable space under your home. It’s the perfect alternative if you’re looking to add more square footage, but you don’t want to build an extension that, for example, takes away backyard space. This added space could be used for storage, a garage, or a nice basement.

If you have a small yard to begin with or you’d like a covered area outside to hosts guests, house raising is a great option for that too. Instead of building continuous walls after the lift, you could build separate piers, posts, columns, or pilings to create an open space.

To strengthen, repair or replace a foundation

Repair or Replace a FoundationThe most effective way to repair or replace a foundation is by first raising or raising and moving your house off of the existing one.

If a foundation needs to be strengthened or repaired, it may go through a process called underpinning, it may need helical piles or it may need both. Underpinning, to put it simply, is when a foundation is installed under the existing one. A lot of foundation issues occur due to poor soil. If this is the case for your home, a type of steel called helical piles is drilled into the foundation and far below the surface into bedrock. This is considered a long term or permanent fix to foundation issues caused by ground or soil movement.

If the damage to your foundation is serious and widespread enough, then it will have to be replaced. The current foundation is excavated to create room for demolition and construction. After the debris have been cleared, new footings are poured, forms are set for pouring foundation walls, the concrete is cured and helical piles are installed if necessary.

Once the foundation has been strengthened, repaired or replaced, the house is then lowered or moved back and lowered to attached it to the new, stable and sturdy foundation.

To increase the value of your home

House RaisingHouse raising increases its value and potential resale by an estimated 15% to 25%. Adding square footage alone increases its value, the more space, the more it’s worth. As for potential resale: houses in flood zones that aren’t raised are nearly impossible to sell because flood insurance rates are so high.

Buyers would have to purchase additional flood insurance on top of buying your house, which would cost them thousands of dollars a year as seen above in figure 3. This may discourage them from buying your home and encourage them to buy one that is already raised. Elevating a home may be expensive, but it would be worth the cost if you are having trouble selling it.
