Repair Cracks in Foundations, Concrete
Floors, and Driveways
Leaking cracks in poured or block foundation walls? Cracks in a concrete slab, basement floor,
driveway, garage, patio, or sidwalk? Leaky floor-to-wall or control joints? Spalling, pitting, or
flaking outdoor concrete? For over a decade, we have been offering professionals and
homeowners the widest selection of the most advanced concrete crack repair products for
permanent repairs of cracks, joints, and spalls in indoor or outdoor concrete.
Save Serious Money – Hiring a contractor to repair a foundation crack can be expensive
(average $500) but surprisingly anyone can repair simple concrete foundation cracks. Whether
repairing cracks that leak or merely for appearance, our comprehensive line of crack repair kits
are designed for permanent concrete repairs! Professional-quality repairs for contractors but easy
enough to use by homeowners!

The Wrong Way To Repair Concrete Cracks
Caulk Failure – The typical homeowner will attempt to fix concrete cracks with silicone caulk
but this is only a superficial repair. Water will fill the inside of the crack and cause efflorescence,
which will eventually loosen the caulk. In couple years, the caulk will lose its bond and start
peeling.
Do Not Use Hydraulic Cement! – Disappointed, the homeowner will remove the caulk, chisel
out the crack, and fill it with hydraulic cement. But hydraulic cement does not bond well to
concrete – that's why it needs an inverted V-groove to hold it in. Additionally, hydraulic cement
is very rigid. As concrete continuously moves, shrinks and expands, the rigid "rod" will loosen.
Efflorescence ("white powder") will start purging around it, soon followed by drops of water.
After a couple of years, water will start seeping in.
An alternative foundation repair method is to excavate and patch the crack on the exterior. This
may not be permanent because all surface repairs will eventually get loose or crack.

DIY Concrete Crack Repair Kits – (8-10 ft.)
Product Information Page
Common Use: hairline cracks, poured concrete walls, leaking
foundation cracks, mortar cracks in stone foundations, radon
prevention
The Ideal Repair Kit for Homeowners! Our DIY Concrete
Crack Injection Kits are designed for use for cracks in poured
concrete walls. They are not recommended for use on concrete
block walls because of their hollow cores. Repair is usually
made from the inside, which avoids excavating the outside of the
foundation wall. The DIY crack repair kits are suitable for
hairline cracks, as well as wide cracks (up to ½”). Low pressure concrete crack injection works
by filling the entire length and depth of the crack. It permanently stops water leaks. It also
protects the concrete. The entire cracks is filled which prevents groundwater from getting into
the concrete.
Our standard injection kits use polyurethane, which forcefully expands to fill the entire crack
(20x its volume). If structural strength is definitely required, use our epoxy crack injection kits,
which is more exacting – the crack must be dry inside. Epoxy does not expand and if there is a
void, will run out of the back of the crack.
Material(s) Needed: Standard/Single cartridge caulking gun
Coverage: 8-10 linear foot crack

PROFESSIONAL Concrete Crack Repair Kits – (30 & 60
ft.)

Product Information Page
Common Use: basements, multiple cracks, dams, commercial

cracks
The Complete Kit for Waterproofing Contractors! Like the
DIY Kits, our professional toolkits use expandable polyurethane
foam and/or a rigid injectable epoxy. The PRO Crack Repair
Kits include a dual-caulking gun making injection easier and the epoxy surface seal cures much
faster in comparison to the surface seal for our DIY Kits (less waiting). The expandable urethane
foams adheres tenaciously to dry and wet surfaces, it is suitable for both dry or wet cracks. Its
low-viscosity (100 cps) and forceful expansion on contact with water make it suitable for both
hairline or wide cracks. Replacement kits, materials, and accessories are available, as well as
special surface sealers and injection polymers needed by contractors.
Material(s) Needed: None, Complete Kit
Coverage: Available in 30 ft. and 60 ft. kits
