How to repair a concrete wall?

Quick Read Concrete Repair is a sanded acrylic filler designed to match the colour and texture of the surrounding environment. Surface concrete repair can be used on vertical or horizontal surfaces. In addition to being an eyesore, a hole in an exterior concrete wall of your home creates a point of weakness in the structure that can allow moisture to penetrate. Once inside the wall, moisture can cause leaks, crumbling and rusting of rebar.

Patching these holes is a necessary part of keeping the concrete foundation wall in good condition. If your goal is to improve the appearance of the wall, a smooth surface is also easier to paint. An ideal patch for both purposes is hydraulic cement, which expands to fill cracks and holes as it dries. There are many products available that can be used to fill and seal the crack, including ready-mixed concrete.

If using concrete to "patch the crack", apply masonry adhesive or some type of bonding agent to the inside surface of the crack. Then drive the concrete into the crack until it is completely filled; do not leave a depression along the surface of the patch. Use a trowel, trowel, brush or broom to even out the texture of the adjacent concrete finish. Tubes of Liquid Concrete Repair (LCR), a viscous epoxy that comes in a caulk-type cartridge, and seven plastic injection ports that introduce the LCR deep into the crack.

Therefore, before finishing your basement or even for an uninhabited but dry basement, one component of your waterproofing plan should be the repair of cracks in the concrete walls. Epoxy products can be used to fill cracks up to ½ inch wide, but will not adhere to wet or "green" concrete. Easy, inexpensive and simple to do, the main purpose of this concrete repair is to block water from seeping into the basement. Concrete walls that need to be structurally sound can be repaired with a low pressure crack injection method.

Before beginning to repair the concrete crack, use any combination of wire brush, vacuum or pressure washer to remove any oil, dirt or debris from the surface of the concrete wall and the inside of the crack. Various masonry patching products, such as hydraulic cement, do an adequate job of filling cracks in concrete walls. The next step is to install short pieces of steel into the deep holes to help bond the repair concrete to the old one. Cracks that form in a concrete wall, particularly a basement wall, due to settlement, frost or soil movement, can be structural or non-structural.

Cracks in concrete walls, such as those in basements, can quickly develop into larger cracks and can allow moisture to penetrate. Structural repairs reattach the wall so that it is as strong or stronger than its original state. If a repair is needed, most engineers develop a plan that can be used to obtain competitive bids from contractors. Repairing cracks in a concrete wall is a simple procedure that is usually completed in about a day.

A remodeling and repair specialist with over 20 years of experience, he is also a Certified Pool Operator and holds an EPA universal coolant certification. The wall must be clean because the last step of the repair will be a thin coat of stucco that will actually dress the wall. Unfortunately, the curing process causes the concrete to shrink slightly, often resulting in hairline cracks.
