Basement Lowering

If you are thinking about your basement as great extra space, it may mean hiring a professional to changing the ceiling height.  It can increase usable space by 50% if completed correctly.  This would give you a wonderful home office or den. 

To raise a basement ceiling there are two options.  One is benching and the other is underpinning. 

Underpinning

Underpinning can cost a few thousand dollars or more depending on the amount of work involved.  It is a framework that expands the height of the basement as well as increase the available square footage. It involves:

  • Engineer who produces drawings and applies for the appropriate licenses
  • Removing the basement concrete floor and excavating soil.
  • Locating the pins.

After carefully examining the situation, the engineer may recommend new posts.  That would include new footings along with the posts.  Pins are also inserted into the two-inch space along the current footings to secure the floor and to ensure a long lasting repair. 

Then pipes are installed.  If necessary, a sewer injector is also installed.  

After all this a waste framework is laid to waterproof the area.  On top of that a minimum of three inches of small rock is set and then the concrete is poured and levelled appropriately.
