What Is Concrete Wall Sawing?
Concrete wall sawing is a process of cutting through concrete walls using a specialized saw. The saw is mounted on a track that is attached to the wall. The saw is then guided along the track to cut through the concrete.
This process is often used to create openings in concrete walls for doors, windows, or other openings. It can also be used to cut through concrete walls for demolition purposes.
A circular blade is used to make gaps in walls or to remove damaged concrete. These blades can slice through walls up to 24 inches thick.
Concrete is widely used to make walls in construction because it has high compressive strength, making it an excellent building material for spanning large spans that steel cannot.
Walls are one of the most crucial components of a structure, making concrete wall sawing one of the most critical components of structural rehabilitation or alteration.
Concrete wall sawing is used to remove or cut away concrete or masonry walls by cutting off damaged parts, leaving the wall’s structural integrity intact.
The wall sawing process involves vertical cuts into a concrete or masonry wall. After you make the cut, a blade is inserted and moved horizontally across the cut, removing any debris and debris that fell between the studs.
This process allows an open void to be created in the wall and can be completed easily without disturbing any of your other property’s structures.
What Type Of Joint Is Typically Required In A Concrete Masonry Wall?
Concrete masonry walls are a popular choice for homeowners and businesses due to their longevity and ability to withstand a lot of wear and tear. However, the control joint is one area where concrete masonry walls can be susceptible to failure.
A control joint is typically required in exposed above-grade concrete masonry walls, where net aesthetic shrinkage cracking may detract from the appearance of the wall and limit moisture or air infiltration.
Different techniques may be used to install it depending on the type of joint required. For example, control joints may be installed with a steel rebar cage, which is then covered with a concrete overlay. Alternatively, a metal strap may be used to attach the cage to the masonry.
Regardless of the technique used, it is important to use a qualified contractor to ensure the control joint is installed correctly and withstands everyday use’s stresses.
How Do You Fix A Spalling Concrete Basement Wall?
Spalling is the formation of a succession of scales or huge concrete chips in your concrete. The spalled surface looks to be separating from the surrounding concrete.
Carbonation of the concrete, when carbon dioxide combines with compounds inside the concrete, is the most common cause of spalling.
- Scrape away any loose concrete from the spalled area. A cold chisel and hammer can remove chipped or splintered fragments.
- Cut a three-eighths-inch-deep square around the spalled concrete using a circular saw.
- Break the concrete in the cut area using the chisel and hammer. Break away any concrete that is linked to the reinforcing bars beneath the surface of the concrete.
- Using a wire brush, remove any rust from the bars. Examine the concrete-covered ends of the bars. If the rust persists, cut and remove away the concrete until you reach a piece that is not corroded.
- Apply anti-rust paint to the rust-free bars. To ensure effective rust protection, apply two coats of paint 10 minutes apart.
- Apply an epoxy glue layer to the cleaned concrete surface. Allow drying until the glue is sticky but not wet. The glue will aid in the bonding of the old and new concrete.
- In a huge bucket, mix a batch of concrete. Use permeable concrete, which allows the concrete to breathe and prevents more spalling from retained water.
The concrete should be mixed thickly enough so that it does not sag when applied to the wall’s vertical surface. To mix the concrete, use a drill with a paddle bit.
- Using a trowel, fill the hole in the concrete with the new concrete mix. Fill the hole, leaving no gaps that might undermine the wall.
- Using the trowel, level the surface of the concrete patch with the surrounding wall surface.
- Cover the fresh concrete with a plastic sheet to prevent the concrete’s water from evaporating too rapidly while it cures. Lift the covering after 48 hours and sprinkle the concrete with a thin mist of water to keep it moist.
After two weeks, remove the covering and allow the concrete to cure completely for another week to ten days.
