Abstract
A crack (12) in a concrete, cement or masonry wall (10) is repaired by injecting a fluid, liquid latex (14) into the crack (12). The exposed surface of the crack (12) is covered with a liquid, impermeable barrier (20) and then the fluid, low-viscosity, liquid latex (14) is injected through the barrier (20) into the crack (12). The liquid latex (14) subsequently cures into a solid, elastomeric state. The latex (14) substantially fills the crack and allows shifting of the wall (10) due to temperature and pressure changes or settling of the wall (10) without damaging the cured latex (14) or causing any further growth of the crack (12).
Claims20
A method for sealing cracks in cementatious, concrete or masonry structures comprising the steps of:
- applying a liquid-impermeable barrier material to a structure containing a crack over substantially the entire length of the exposed portion of the crack;
- injecting a fluid, liquid latex composition through said liquid impermeable barrier into said crack at at leastone location behind the barrier so that said latex substantially fills the crack, said barrier preventing the latex from flowing out of the crack;
- said fluid liquid latex composition having a low viscosity so as to penetrate into the crack interior and curable into a solid, elastomeric state;
- and,
- curing said latex composition in place into a solid, elastomeric state.
A kit for sealing cracks in cementatious, concrete and masonry structures comprising:
- a fluid, liquid latex composition which is deposited in a crack, said latex being curable at ordinary temperatures and pressures into a solid, elastomeric state and having a low viscosity so as to enable said latex to penetrate deeply into said crack;
- applicator means for injecting said latex composition in said crack;
- and
- liquid-impermeable barrier means for application to an exposed surface of said crack for preventing said latex composition from flowing out of said crack during injection;
- wherein said kit can be used to repair cracks by injecting the latex composition into said crack by use of said applicator means after applying said barrier means to the exposed crack surface to prevent said latex composition from flowing out of the crack.
