Epoxy Crack Injection - May, 6 2011
Author: Brandon Huinink
Epoxy crack injection is a different
animal to it's polyurethane injection counterpart. Urethane
injection loves water, in fact it is necessary to properly cure the
resin, but with epoxy injection, water must not be present during the
complete procedure. This method of crack injection is more for
structural repair.
If your structure needs not only to stop
leaks
but the structure is in danger of being weakened due to the crack,
epoxy injection is the method of choice. Instead of drilling holes
into the crack, plastic surface packers are installed directly over
the crack every 4 inches and fastened with epoxy to the the concrete
structure.
The cracks are covered with epoxy as well to help force
the material to the back end of the slab. Once the epoxy has been
injected at high pressure, there is a curing time of 24-48 hours.
After the epoxy has cured, grinders are used to remove the epoxy, packers and clean up the crack.
Strength to the structure is now
restored and the crack is now water-proof.
These procedures seem simple but many
can attest that the smallest little error and the method does not
work. These notes are not enough to understand the crack injection
methods and qualified contractors such as Huinink Construction should
be contacted.
