Wall Sawing or Vertical Concrete Cutting Details

Wall sawing is the cleanest, safest, most effective way to create door and window openings in concrete. Despite the name, concrete wall cutting is not limited to walls—we use the same tools and techniques to make flush cuts into ceilings and floors.

The old ways of pneumatic concrete breaking are obsolete. With 36 inches of depth, no overcuts and flush results, basement window cutting will not cause any structural damage.

Frequently Asked Questions

You should be as precise as possible with your measurements. You’ll need to have an exact, correct layout before we begin cutting to ensure the desired final opening dimensions. Once an opening is complete, there’s no give to the concrete. Important note: use rough dimensions where applicable, such as egress windows or door installations. If you use the exact dimensions of your window or door, it’s likely it won’t fit.

When drilling cores, pipe size and core bit size are not the same thing. A four-inch pipe will not fit in a four-inch core. You need to measure the outer diameter of the pipe being installed, add the necessary clearance, then calculate the required core size. Our operators don’t handle the coring dimensions and will drill the core sizes you request. Consult with our dispatcher when requesting service to ensure we have the proper size core on hand to complete your job.

Heavy. Typical concrete weighs 150 pounds per cubic foot (a space measuring 12 inches on all sides).

Cutting manageable pieces is an important part of planning, especially when cutting large openings in walls or trenches in slabs. Our sales team and operator can help you determine a manageable size.

When cutting smaller openings, use the following guidelines:
● For jobs requiring hand removal in a slab, assuming 6” deep concrete, cut 1.5-square-foot pieces.
● For jobs using the same 6” deep slab with equipment such as a skid steer, cut 3-square-foot pieces. In some cases, larger pieces may be acceptable.
● For jobs with thinner slabs, you can cut a larger square footage. With thicker slabs, cut a smaller square footage.

We can cut concrete slabs on a floor 36 inches deep with our diesel slab saws and 24 inches deep with electric slab saws. We have a number of low-emission diesel slab saws available depending on your needs. Contact our sales team for more details.

We can cut concrete walls up to 36 inches thick with traditional cutting blades and can cut even thicker walls with our wire saws.

We’re able to engineer a sequence of cutting in order to efficiently cut and remove concrete thicker than 36 inches in spaces that don’t allow access to wire sawing.

Our wire saw can cut round holes up to 33 feet in diameter.

We prefer to cut egress windows from the exterior of the home. It’s faster, more efficient and creates a considerably smaller mess. Our operators will need access to the interior of the home to visually inspect the area and ensure there’s no potential for damage. For the safety of your home and our operator, we recommend you survey and inspect the interior cutting area for plumbing and electric lines and remove anything you find prior to our arrival.

Overcuts are the lengths of saw cuts that extend beyond the actual opening being created in concrete cutting using blades.

Yes. There are three options to eliminate overcuts:
1. A combination of handsaws and chainsaws. This method is fastest but far more labor-intensive, requiring special equipment and increased cost.
2. Ribbon-cutting is a process in which we perform a series of cuts in the same direction. The cuts are only a few inches apart from one another and made at partial depth. This is more cost-effective and efficient, but you’ll need to have the ability to chip the concrete. This process is also used to reduce risk and danger when cutting concrete where plumbing or conduit is in or below the slab.
3. Double cutting is a process in which a second cut is performed around the border of the slab and can be snapped off, allowing the middle pieces to be pulled free without damaging the adjacent slab. This requires a limited amount of chipping in the corners and is the most popular and least expensive technique.

No. You should contact a professional who specializes in door and window installation.

We’ve cored over 70 feet deep in a foundation and cored over 20-feet-thick wall. Distance above the slab or in front of a wall, as well as general access, factor into what is feasible. Contact one of our team members for more details.
