Restoring degraded or damaged concrete structures is the goal of concrete restoration. Cleaning, removing unstable concrete, applying repair materials, and finishing are usually steps in this process. By improving structural integrity, longevity, and aesthetics, it seeks to prolong the life of the concrete component.
2. EPOXY INJECTION
• Epoxy injection is an economical
method of repairing non-moving
cracks in concrete walls, slabs,
columns and piers and is capable
of restoring the concrete to its
pre-cracked strength.
• Prior to doing any injection it is
necessary to determine the cause
of the crack. If the source of
cracking has not been determined
and remedied, the concrete may
crack again.
3. • Epoxy injection is commonly used to restore the pre-cracking
condition of the member without increasing its strength.
• The epoxy tensile bond to the concrete substrate is stronger than the
concrete’s tensile strength.
• Future cracking may occur at the same load as that of the original
uncracked member but at different locations.
