Concrete Crack Sealing:Stop Leak In Concrete

Water leakage via cracks and joints through concrete is an on-going headache. When concrete shifts, it usually cracks. The size of the crack depends on the amount of shifting, but the greater problem is the water leaking through the crack.

Freeze-thaw damage, corrosion, structural decay and even failure can all be evidence of cracks and water. Frigid weather conditions may cause ice build-up both above and below the surface. In addition, the water may damage the contents that are housed in the structure.


To stop the leak,We use hydrophilic or hydrophobic resin grouts, which are designed specifically for sealing leaks in concrete. These chemical grouting compounds are viscous liquids that look like honey. When mixed with water, the grout expands and quickly cures to a strong, flexible rubber.

Crack injection with chemical grout can not only stop the water, it can stop or slow the deterioration of rebar or other internal features of the concrete. This success is due to the placement of chemical grout throughout the depth of the crack, compared to only surface sealing of the crack with hydrolic cements, caulkings or surface applied products. This process is performed through our drill and injection method. The nature of the leak will determine the approach used by our technicians.

Hydrophilic grouts readily mix with water and seek out water to get an excellent "bite" into the pores of wet concrete. This is important when trying to seal a crack in wet concrete. Hydrophilic grouts are used to stop leaks through cracks and joints in underground structures. When cracks or joints open and close with temperature changes, a tight water seal and bond is maintained due to the flexibility of a hydrophilic grout.

No Expensive Excavation Required

Hydrophobic grouts are typically used to fill voids and stabilize soils due to their low viscosity, high expansion rate, and ability to set up under wet conditions without diluting. A hydrophobic resin repels water. When injected into loose soil or voids, it expands and replaces any water present. Because rigid hydrophobic material is not affected by fluctuation in the moisture content of soil, it is virtually unaffected by water table. It retains its strength, size, and impermeability under almost all soil conditions.
