Hole Drilled Through Footing
Any holes that have been drilled
through the concrete footing can weaken the foundation.
However, a hole like this is not going to create a
problem, that should concern most homeowners.
This hole was probably drilled from the inside of the
home to allow access from the outside of the house, for a telephone,
electrical or cable wire.
Larger holes that are drilled through your concrete footing could become
structural issues, whether or not they are directly under a load bearing
structural post. The size of the hole and its location could create
problems.
For example, someone has drilled a 3 inch hole through a six-inch wide
stem wall footing, to allow for a new plumbing pipe that will be used
for a bathroom remodel.
The footing is holding up a 2 x 4 load bearing wall
for a single story home. The 2 x 4 wall is supporting the ceiling joist
and the roof rafters, only. There is a good chance that the 3 inch hole
will not create a structural problem.
This is just an example however,
and I would suggest contacting a structural engineer before drilling any
holes, through any footings, for your homes safety.
Home Repair Tip: Simply clean the hole the best you can, using a round
bristle brush and then fill the hole with a concrete epoxy or any type
of concrete repair product. Holes like this can allow moisture and small pests to
enter your home and should be filled as soon as possible.
