Why is reinforcement used in concrete?

Reinforcement within concrete creates a composite material, with the concrete providing strength against compressive stress while the reinforcement provides strength against tensile stress. ... These threads should act just like the deformed ridges in normal rebar to create some grip between the concrete and steel.

Do you need reinforcement in concrete?

Do All Concrete Projects Need Reinforcement? No, they do not. Larger projects or slabs may need steel reinforcement to provide support or extra strength. Wired mesh can also help resist cracking.

Does fiber reinforced concrete need rebar?

Sometimes you need steel fibers, and sometimes you need rebar, and only in a few limited situations can one effectively replace the other. To put it simply, steel fibers prevent cracks, while rebar limits the width of cracks. ... You can't do that with rebar. Example 2 is a concrete highway two miles long./span>

Should you put a vapor barrier under concrete slabs?

Water vapor will always move from a high relative humidity environment below the building into an area of low relative humidity – even through concrete. That's why nearly every expert in the concrete industry recommends a below-slab vapor barrier to stop the vapor drive of water upward and into your building envelope./span>

Should you put plastic under concrete driveway?

It is still a good idea to have protection against rising damp even though you don't strictly need it. In fact, most professional shed slab builders will install a polyethylene membrane under a shed concrete slab even if it is not specified./span>

Does concrete need moisture barrier?

A concrete vapor barrier is any material that prevents moisture from entering a concrete slab. Vapor barriers are used because while fresh concrete is poured wet, it's not supposed to stay that way. It needs to dry and then stay dry to avoid flooring problems. ... This is why a vapor barrier under concrete is essential./span>

Is concrete a vapor barrier?

Lots of vapor moves by air movement, not a heck of a lot of vapor moves by vapor diffusion. The concrete slab is the air barrier, and the ripped and torn and punctured polyethylene sheet is the vapor barrier. It's that Fick's Law thing./span>

Can you put a vapor barrier over concrete?

Subfloor Material In high-humidity areas, moisture will move to a relatively low-humidity area, even through concrete. Therefore, because concrete is porous, it's a good idea to install a vapor barrier over your concrete subfloor before installing your flooring./span>

What can I use for vapor barrier under concrete?

The most obvious best practice is to install a sub-slab vapor barrier in the first place. I recommend a minimum 10-mil-thick polyethylene material, even if your local building code allows a 6-mil, as it lasts longer and is less prone to punctures./span>

Will expanding foam lift concrete?

The foam will fill up the parts of the concrete that are uneven and will raise it to the proper height. ... Patch up the holes with concrete, and your new driveway (or sidewalk, or walkway) will look good as new.

How do you find voids under concrete?

To detect voids under concrete, mudjacking contractors use a high-frequency, ground penetrating radar system. The GPR equipment sends a radio pulse down into the ground. When the transmission reaches an anomaly in the soil, a reflected signal is sent to the receiver.
