Is LCR harmful or dangerous?
LCR is 100% non-toxic in a cured form and is completely safe when used in accordance with the manufacturer’s printed instructions.
LCR - LIQUID CONCRETE REPAIR
For cracked and leaky foundation repair
How is the LCR kit different from other crack repair materials?
Other crack repair products such as hydraulic cement, tars, latex coatings and caulks are all temporary ‘Band Aid’ repairs that are surface applied and rely on a surface bond to work. Moisture in the crack will ultimately break down this bond, and the repair will fail. Even chipping out the crack and patching with hydraulic cement gives a nominal repair which will re-crack and fail if the foundation shifts. Other repair products cannot withstand the movement in foundations caused by soil pressures and seasonal thermal changes. The LCR Kit will fill the entire crack with high-strength epoxy resin that permanently bonds the crack and is flexible enough to withstand movement in the foundation. Filling the crack with epoxy is the only way to ensure that water will not penetrate into the crack.
Can I repair a crack that is actively leaking?
No. (See POLYFOAM) LCR works best when installed under dry conditions and will permanently prevent further seepage from the crack.
How is LCR so much better than other materials?
Products such as caulks, sealers patches and adhesives are temporary repairs which require re-application over a period of time. LCR is specifically designed to provide for a PERMANENT repair which meets or exceeds the original strength of the item repaired. LCR is so strong it can withstand pressures of over 14,000 pounds per square inch! LCR is a very low cost alternative to the expense of replacing a driveway, sidewalk, pool, etc.
The LCR Kit is an easy-to-use, complete repair system for cracked and leaky foundations specifically designed for DYI and contractor use. It comes with a crack sealer, injection ports, and two ten-ounce LCR injection cartridges, which is enough to repair an average 8-foot foundation crack.
What other tools do I need?
A standard caulking gun for dispensing the injection liquid and a spatula for mixing the crack sealer.
Can the crack sealer be applied to damp concrete?
Yes. Again, every attempt should be made to install the LCR system under dry conditions; but when working under damp conditions, a longer set time for the crack sealer to gain bond strength should be allowed prior to injecting the LCR injection resin. Fans or a portable hair dryer can be used to help dry the crack surface prior to application of the crack sealer.
