HOUSE/GARAGE Foundation


It appears that my house foundation was poured separately from my garage footings...so the garage is slowly pulling away from the house and the garage floor is developing a large crack down the center. What is the least expensive way to fix this?

HOUSE/GARAGE Foundation


Not much information to give anything more than a quick guess -

Where are you and what is the climate?

How old is the house and how old is the garage? - And are they attached and by what method.

Is the garage floor a floating slab inside frost or stem walls or does the slab/foundation support the roof?

Is the garage floor crack a typical shrinkage crack or is it related to soil settlement and movement?

Before you do a quicik fix you must know what the cause is and how the areas are used and connected.

It could be just a quck patch that may last until you sell in 10 to 50 years or it may be an indication in the basic structure. - I know you do not want to be terrorized, but you should be alerted if there is a problem.

HOUSE/GARAGE Foundation


The house and garage were built in 1985. The attached garage footings and 4' walls were butted up against the poured house wall and foundation. Not sure if there is any actual rebar ties at attachment.

The crack is down the center along the saw crack. It is about 1/2 in wide. It appears the garage walls are moving outward.

To begin - without seeing a picture, a crack that close to the sawed joint means that the saw cut was way too shallow (should br 1/4th of the slab thicknees).

The width of the crack is a bigger problem. Since the slab is moving away, there must be a problem with the soil or the footings to create a crack that large. I assume the house is not moving, so that the outer edge is moving.

Is the gargae on a slope or is it on fill?

Sorry, I meant the saw crack was getting wider...not a new crack alongside
