you repair a cracked or broken septic tank?
Some of this depends upon the county in which
you live. I have spoken to county environmental health
employees throughout the State. I asked them
specifically about repairing concrete septic tanks and all of
them have a different opinion.
Some of them flat out said "no". And most
others said they would consider it on a case-by-case basis.
I have a background in concrete fabrication and
epoxy work and so I know many cracks and holes in septic tanks
can be repaired.
It is also possible to repair cracks both above
and below the waterline. A proper repair will result in
a watertight tank which holds water above the waterline for
24-hours; this is a standard test of tank integrity.
Holes in the bottom of a tank can be
repaired. You pour a new tank bottom.
If a tank's lid is broken, you buy a new lid.
If it is an old tank with slab type lids, I can
fabricate a new lid for you at the site with rebar or metal
wire mesh reinforcement.
A major factor which determines the
viability of repairs to a tank is: Does the remaining concrete
easily break apart? You can determine this by probing
(jabbing) the concrete in the surrounding area with a pointed
piece of metal such as a screwdriver or a pointed piece of
rebar. If large areas of concrete easily flake away, a
repair is probably a waste of your money.
Basically, for a concrete repair, you examine
the tank like a dentist. You remove all the decaying,
loose concrete and replace bad areas with new concrete and
How much I am willing to argue with a county for a particular
repair depends on how long it will last. If I think that
a repair will not last for at least five years I will tell
you. I am very reluctant to do repairs which will not
last at least five years.
In North Carolina concrete septic tanks
are fairly inexpensive. You need to compare the cost of
the repair: time + materials + excavation costs to $1500-$2000
for an installed brand new tank.
For anything but a tank lid replacement, you should
also factor in the cost of leaving your home for a l-o-n-g
weekend. Septic tanks cannot be repaired when they are
currently being used.
