January 15, 2021

Sharing is caring!

No matter the cost of concrete coring, this job is worth having done precisely and professionally! Trying to manage concrete drilling, and coring without the right tools and techniques often results in crumbling concrete, overly deep cuts, and damage to surrounding areas. Cutting through live electrical wires or cables and other buried utilities can also mean serious injury!

How Much Does It Cost to Cut a Concrete Slab?

Concrete Slab or Flat Sawing Average Costs

Slab or flat sawing is used to cut along concrete floors or walls. Slab sawing offers precise cuts for roads, bridges, parking lots, and small spaces such as garage floors. Flat sawing can be used to break up poured concrete or to create trenches and joints between concrete slabs without damaging the surrounding materials.

Concrete Core Drilling Average Costs

Concrete core drilling cuts holes in concrete; these openings might be used to install everything from the conduit to plumbing pipes and other fixtures or to break up concrete for easy removal. Concrete core drill bits are available in widths of 1/2” to 60”, allowing a concrete cutting contractor to create precise cuts and holes.

Core Drilling Hole Size, in Inches Floor Cost/Inch Wall Cost/Inch Depth, in Inches Outdoor Gas/Linear Foot Indoor Propane/Linear Foot
1-2.5 $3.50 $4 1-1.5 $0.6 $1.50
3 $4 $5 2-2.5 $0.8 $1.50
4 $5 $6 4 $1.60 $2.25
5 $6 $7 6 $2.10 $2.50
6 $7 $8 8 $2.85 $4.50

Concrete Chainsawing Average Costs and Prices

Concrete chainsawing uses a specialty, diamond-tipped blade that allows for precise cuts through concrete and brick. Chain sawing is an excellent choice for creating openings needed for doors and windows, or for cutting through concrete without damaging surrounding materials such as already-installed windows.

Chain Sawing Depth, in Inches Per Linear Foot Small Scale Sawing, in Inches Block Cost/Foot Filled Block Cost/Foot
8 $35 4 $4 $7.50
12 $65 6 $6 $12
16 $85 8 $8 $18
18 $95      

Now that you know some average prices for concrete coring and other cutting, note some added questions you might have about concrete mixing, pouring, and fabrication.

What Is a Concrete Core Test?

A concrete core test is something of a strength test for concrete. This test checks if concrete complies with strength-based demands, regulations, or other criteria for a structure or surface. Depending on the core test, the concrete might need strengthening with rebar, steel beams, underpinning, new concrete layers, and other protective measures.

How Much Is 2 Cubic Yards of Concrete?

A standard 10-foot by 10-foot patio needs about 2 cubic yards of concrete. On average, concrete costs about $120 to $150 per cubic yard, so $240 to $300 for 2 cubic yards of concrete. If you’re thinking of pouring your own patio concrete, remember that this price is just for the concrete; some concrete pouring contractors might charge extra for delivery, removing old concrete, and other such services.

Many homeowners might also appreciate concrete stamping and staining, to create the look of paver stones. The cost for stain and tools needed for stamping, or a concrete contractor needed for stamping and staining, also need to be considered in these overall costs!

How Many 80lb Bags of Concrete Make a Yard?

Most concrete projects are measured in terms of cubic yards, or 27 feet (3 feet x 3 feet x 3 feet). Most 80lb bags of concrete provide about 0.6 cubic feet, so you’ll need 45 80lb bags for every cubic yard of poured concrete.

As with all home improvement projects, it’s always recommended that you purchase more concrete than you think you’ll need to ensure you have enough material in case of improper mixing, spilling, inaccurate measurement, and the like. A spare bag or two of concrete also lets you make future repairs without having to find the right concrete mix on store shelves!

Is It Cheaper to Mix Your Own Concrete?

Mixing your own concrete is cheaper than paying a concrete pouring professional, but it’s not necessarily recommended a homeowner go the DIY route for concrete mixing and pouring! Note a few reasons it’s best to rely on a pro no matter your concrete mixing and pouring costs:

  • Using the wrong ratio of concrete and water results in a weaker surface that is likely to chip, crack, and spall sooner than it should, once that concrete sets and cures.
  • Concrete begins to set and cure as soon as it’s mixed, which is why concrete pouring contractors use a mixing truck and keep that concrete in motion as they pour it. This ensures the concrete doesn’t set too quickly and you find it difficult to pour or need to dispose of that concrete altogether!

Concrete Pouring Tips

A concrete pouring contractor might use reclaimed concrete pieces in new mixes, to keep that concrete out of landfills and reduce the need for new materials. However, he or she will know the best concrete to add to their new mix and how to ensure it’s blended in completely.

  • Subgrade concrete might be acceptable for a patio and other surfaces that won’t hold much weight, and that have full support under them. However, using subgrade concrete for driveways, garage floors, and porches can result in premature cracking and even collapsing!
  • Because concrete installation contractors pour lots of concrete every week, they can often salvage and use any leftover concrete from your property, also ensuring it doesn’t go to waste and end up in a landfill.
  • Pouring concrete, even for small patching jobs and new patio installation, is often more difficult than homeowners realize. Improper tools and techniques can mean premature damage or obvious, unsightly repairs. A concrete installation company ensures a precise job with every project, so your new concrete or repair work lasts for years.

How Long Does It Take for Concrete to Cure?

Your concrete contractor will note how long concrete needs to cure completely, before you can walk or park on that surface. Cure times vary according to the concrete mixture, local weather conditions, and other such factors. However, as a general rule, note how long it usually takes concrete to cure:

  • After 48 hours, forms can typically be removed.
  • Concrete can typically handle light foot traffic after 48 to 72 hours.
  • After 7 days, concrete has cured enough to manage light vehicle traffic.
  • Concrete is typically fully cured and can manage all vehicle traffic, including heavy vehicles, after 28 days.

Can You Pour Concrete In the Rain?

Concrete mixtures need water for proper pouring consistency; however, as with any home improvement material such as paint, sealant, adhesive, and so on, too much water can mean runny concrete that doesn’t set properly and which soon cracks, chips, and spalls. Weakened concrete also gives way under pressure.

Unfortunately, there are not many ways to salvage poured concrete ruined by heavy rainfall. In most cases you might need to tear up that concrete and replace it, which is both costly and time-consuming. To avoid this risk, ensure you pour concrete only when you can count on dry weather and cover that newly poured concrete with tarps as needed, if rain should move in after your new concrete installation.

If your new concrete has been subjected to rainfall, note some tips to consider and mistakes to avoid:

  • Don’t add dry cement over the top of the concrete, assuming it will just soak up water. Instead, this will only create a weak top layer likely to crack and spall!
  • Don’t start mixing any standing water into the concrete, thinking you can salvage it by also adding dry mixture or aggregate. Concrete mixture must be accurate for strong, durable pavement and trying to “wing it” with rainwater and dry materials will mean weak, damaged concrete.
  • Use a concrete float, similar to a dust mop or push broom, to push water off concrete surfaces. This is your best chance of salvaging rain-damaged concrete!
