Lowering a Basement Floor

Most basements of older homes within the older areas of our cities and towns are not high enough to walk around comfortably. - It's common thing for these century homes and pre 1940 homes the basement was very often referred to as the 'cellar' and was used as a utility space where such items as the furnace, (coal storage / oil tank storage in older homes), water heater, breaker panel or fuse box, systems were located.

With proper engineering and modern construction and waterproofing technologies it is easy to convert these basement storage spaces into livable space by lowering the floor in the basement and waterproofing the foundation.

Are you thinking about having your basement lowered to increase the basement ceiling height and gain some additional living space?

Basement Lowering Methods

Prior to existing basement floor can be lowered, the foundation must be stabilized so that the basement excavation does not compromise the foundation resulting in cracks, sinking or worse ... collapse of the home.
Basement Lowering, also referred to as Basement Dig Out, Dig Out Basement Floor, Basement Excavation, Basement Floor Lowering, Lowering Basement Floor, Lowering Basements, Increasing Basement Height, Digging Down a Basement, Digging Out a Basement is done by underpinning the foundation or installing bench footings and removing the existing floor, digging the basement to the new elevation and pouring a new concrete slab. Separated from stabilizing a damaged foundation, the most common reason someone would underpin a foundation or constructing bench footings is to accommodate lowering the basement floor to increase the ceiling height of the basement.

Benching - Bench Ledging - Bench Footings

Basement Lowering - Benching

Benching or Bench Ledging or Bench Footings - A new foundation wall is installed by digging down away from the internal wall just above the existing footings. The ledge or bench will extend into the basement reducing the finished floor space slightly. The depth of the ledge (or bench) that is created will determine the width it will extend horizontally into the basement. Commonly, the width of the bench footing will be equal to it's height.
With benching there is a little loss of floor space.

Foundation Underpinning

Basement Lowering - Underpinning

Foundation Underpinning involves excavating sections under the existing foundation wall to the desired depth and pouring new concrete under the existing foundation. This maximizes finished size of the lowered basement since there is no loss of horizontal space as there is with the bench footing method of basement lowering.
