How Strong is The Concrete?

What’s the most important property of concrete? It’s compressive strength. That’s how much pressure the concrete can take before it fails (cracks). Compressive strength is measured in pounds per square inch (psi). The greater the psi, the stronger the concrete. A residential sidewalk should be at least 4,000 psi; a driveway, 5,000 psi. If you live in a cold climate and need to de-ice your driveway, get at least 3,500-psi concrete with air entrainment. Air entrainment mixes tiny bubbles into the mix that help prevent water from entering cracks and freezing and expanding there to break up the concrete. Check out our Concrete Calculator to see how much concrete you’ll need for your job.

Which Type of Concrete Foundation is Best?

It depends on what you’re pouring, your climate and the location of the pour. Most contractors will use all-purpose at a 4,000 PSI rating. Mortar mix is a blend of Portland cement, hydrated lime and masonry sand. It’s commonly used for above-grade exterior walls as well as interior load-bearing walls and chimneys. Fast-setting concrete can be applied in cooler weather than standard concrete—it sets quickly without shrinking, which may cause cracks if there’s not enough time for it to cure properly.

Cement itself is actually an ingredient in concrete; it’s a binding agent that helps hold the aggregate (stones or gravel) together. Cement can be mixed with water, then poured or pumped into place and left to harden—no mixing required since it hardens when exposed to air. This makes it ideal for smaller jobs where no mixing equipment would be needed anyway (such as filling small cracks).

Mortar is similar to concrete—both contain cement as an ingredient—but much finer aggregates are used in mortar, along with sand and water. The mortar mix ratio is 1 part cement to 4 parts sand by volume, but you’ll need about 5 times more total volume of material: 5 parts sand/gravel aggregate plus 1 part cement equals 6 parts mortar by volume.

What Pouring Conditions are the Best?

Water is something that is so easy to get, but can be so difficult to pour.

If you are lucky enough to have a friend or two who can help pour your tea for you, that’s great! But if not, then simply strike up a conversation with a passerby. If they’re willing enough to pour your tea for free, ask them how they know where it goes and things such as that. If they’re not interested in pouring your tea at all, just thank them and move on.

What Type and Size of Footing Do I Need?

Footings are a foundational structure that support the house itself. The depth at which you dig will determine the size and cost of your foundation, as well as how long it will last.

For a typical foundation, you want to dig down at least 6’ from ground level. If you live in an area with a large water table or a lot of clay in the soil, you may need to dig even deeper for better stability. You’ll also need to check local codes for footing requirements in your area; some require footings that go down 10’ or more, especially if you have expansive soils!

How Thick Should My Base and Slab Be?

• How thick will the concrete be?
• What rebar spacing is required?
• What depth of installation is required for electrical conduit, plumbing pipes and other in-slab objects?
• Are there cold joints or seams to avoid?
• Will you need a clean cut saw joint (for control joints)? If so, what kind of tool will be used to make the cut (a hand-held circular saw, walk-behind saw or stamped with a hardened steel blade)? How wide should it be (1/4 inch to 1/2 inch is common for a clean cut)? Where should it start and end (at the edge of the slab)? Should it go all the way through to the bottom?
• Will you need color-coded cuts for decorative concrete projects such as stained concrete or engraved decorative borders with architectural designs?

What is My Rebar Spacing?

What is My Rebar Spacing?

To begin with, your rebar spacing depends on two things:

• The thickness of your slab.
• The loads that you’re going to be putting on the concrete.

How Do I Avoid Cold Joints and Seams?

Cold joints and seams are major no-nos in the world of concrete. A cold joint is an area where two pours meet that has hardened before the next pour is made. A seam happens when a pour meets a wall or other obstacle, trapping air pockets and creating a visible line in the finished product.

In order to avoid cold joints (and seams), make sure your next round of concrete reaches out at least 2 feet past your previous round’s end point, which will allow the concrete to start to dry at the same time. Using this method creates a “hot” joint, meaning both pours will set together as one piece without any interruption in drying time.

How Do I Get a Clean Cut Saw Joint?

• Use a sharp blade
• Cut perpendicularly to the edge of the slab
• Make sure the saw is square with the slab edge
• Keep your saw moving at a consistent speed for a clean joint
• Use plenty of water over and under the blade, especially when cutting marble or limestone
• Let the slab cure for at least 28 days before you attempt to use it in a project

How Do I Make Color-Coded Saw Cuts for My Decorative Concrete Project?

Q: I’m doing a decorative concrete project where I want to use multiple colors. What’s the best way to make color-coded saw cuts for this type of job?

A: You must make the cuts before you pour and place concrete if you’re using integral pigment, which is mixed into the slab as it’s poured. If you’re using topical coloring products like stains or dyes, however, you can wait until after the concrete is placed and then make the saw cuts. In these instances, it’s best to use a blade with fewer teeth, such as an 18-tooth blade. This leaves a more irregular edge when cutting through hardened concrete than blades with 24 or more teeth. That ragged edge will hide any discoloration caused by dye bleeding over into adjoining color areas on a thin stamped overlay after it has been sprayed on and worked into the surface — which can be distracting when viewed from close up in your finished project.

When Can We Put Concrete in the Ground?

• Can I put concrete in the ground? The rule of thumb is that the temperature should be between 50 and 70 degrees, but below 50 or above 90 can cause problems.
• Will my concrete crack? Concrete needs time to cure and temperatures affect how quickly this happens. If you pour when it’s too hot outside, your concrete will dry before it has a chance to cure properly. Too cold and it may take longer for your concrete to set up. This can create weak spots where cracks can develop later on when the slab expands or contracts with temperature changes in its immediate environment.
• Will my rebar be compromised if I pour in extreme temperatures? It depends on what kind of steel reinforcement you use. For example, epoxy-coated reinforcing steel will not corrode at any temperature, but plain steel rebar may rust more quickly with high heat and humidity.

Ask these questions to get the best concrete foundation.

• What is the square footage of my foundation?

You’ll need to know how much concrete you need before you can order it. Calculate the square footage of your foundation by multiplying the length and width of your foundation. If your foundation has a unique shape, you may have to break it up into smaller rectangles or triangles and calculate each separately, then add those numbers together to get the total square footage.

• How much concrete do I need for my job?

Generally speaking, one cubic yard of concrete poured at 4″ thick will cover about 80 square feet. So if you’re doing a project that requires 200 square feet at 4 inches thick, that’s 5 cubic yards (a little over 1 ton!) of concrete! You can use a calculator or this helpful table from Quikrete or talk with your local ready-mix supplier to come up with an estimate so you know how much product to order.Building a new home? Congrats! You must be excited to see the initial planning and groundwork come together. But before you pour your concrete foundation, you might want to ask yourself some questions.

The following are ten important things to ask before you pour:

1. Is the slab thick enough?

2. What type of reinforcement is used?

3. How fast will the slab be poured?

4. How well has the subgrade been prepared?

5. Will the concrete be cured immediately after finishing?

6. Has an expansion joint been installed around the perimeter of the slab?

7. Will the concrete be integrally colored or finished with a color hardener or release agent?

8. Does the slab need to resist chemical attack or staining? Or will it just be decorative concrete?

9. Will any decorative techniques like stamping, acid staining, sawcutting, etc., be incorporated into the design of the concrete slab?

10. What type of control joints should be installed in the slab after pouring to control cracking and movement?

Concrete is a versatile and durable building material, but it’s not without its risks. Before you make the decision to pour concrete, you should ask yourself some important questions. Here are 10 things you need to ask before you pour.

1. Is your slab in your finished design? If so, any issues that arise with the concrete will be difficult to fix or replace.

2. What’s going on underneath? Has the property been properly prepped for the foundation?

3. What kind of concrete are you using? Does it have all the reinforcements necessary for your project?

4. How will you control cracking? It’s crucial to have a plan for controlling cracks—but make sure it’s one that won’t compromise the integrity of your foundation.

5. Do you have proper drainage plans in place? Drainage is an essential component of foundation plans, so make sure yours meet local regulations and codes.

6. Where will you install penetrations and penetrations through the foundation? These need to be accounted for in advance in order to ensure they’re done properly.

7. Will you use a vapor barrier? A vapor barrier is a crucial component of your home’s energy efficiency—and it won’t work if it’s compromised by improper installation

10. How do I know if my house needs a new concrete foundation?

Have you ever had concrete poured? If you have, then you know that it’s a big deal. A concrete foundation is the basis for your whole house structure.

But not all concrete foundations are created equal. Your foundation needs to be able to withstand the elements and bear the weight of your whole house, so it’s important that you get it right the first time.

Start by asking yourself these 10 questions:

1) What kind of foundation do I need? Slab? Crawlspace? Basement? Each type has its own pros and cons, so make sure you know what each entails before making your decision.

2) What kind of soil will hold my foundation? Not all soils are good for foundations. Ideally, your soil should be able to support your structure without shifting or compacting over time.

3) How deep does my foundation need to be? Foundations aren’t just about depth; they’re also about width. Make sure both are adequate for supporting your home’s weight.

4) How many piers will I need? Piers are a type of concrete block that help support footings, which in turn support your beam and structure. You’ll need enough piers to adequately distribute this weight throughout the base
