Can You Reuse A Concrete Post Footing?

Yes. Many homeowners are tempted to reuse existing footings or foundation concrete that have been in place for years when it comes to home repair tasks.

Footings and foundation concrete that has stayed for a long period might become unstable, fractured, slanted, or heaved, and should not be reused.

Here are a few reasons why old footings and foundation concrete may be unstable:

-The footings or foundation concrete may have been installed using outdated techniques or materials that are no longer applicable.

-The soil around the footing may have shifted over time, causing the footing to become weak and unstable.

-The footings or foundation concrete may have been installed on an unstable foundation, such as a shaky concrete slab or a settling foundation wall.

If you are thinking of reused footings or foundation concrete, consult a professional before starting any home improvement project.

They can help you identify any potential problems with the old footings or foundation concrete and recommend a safe, effective way to replace them.

How Do You Attach Concrete To Existing Footing?

When you are installing a new foundation, it is important to correctly prepare the steps involved in pouring concrete over the existing concrete slab;

1. Step 1: Cleaning Old Concrete Surface

Sweeping soil debris over the existing concrete slab allows bonding to occur. Sand, dead leaves, and gravel must all be removed. A stiff-bristle broom is one of the greatest instruments for cleaning all the particles out of the crack.

This cleaning must be done completely, and it is advised that a pressure washer be used to remove any concealed particles. Another technique to obtain outstanding cleanliness is to wash the surface using liquid detergent or degreaser to remove persistent marks.

We offer concrete cleaners that may be used to scour areas that are tough to clean. The final step in cleaning is to wet the surface.

2. Step 2: Setting Up Slab Perimeter

Measure the perimeter where the concrete will be poured over the existing slab, depending on the desired usage of the slab and the loads that will be placed on it.

The slab’s thickness is predetermined. The measurements taken may then calculate the amount of concrete needed.

The braces are normally constructed of wood and are erected around the area to be filled with concrete.

It is necessary to ensure that the braces are uniformly distributed, which can be accomplished using a bubble or string. A wire mesh is required on the bracing to give support for the thick concrete slab.

3. Step 3: Pouring a Primer Coat

The slurry of water and cement is applied to the existing slab to provide a bonding layer between the old and new concrete to be placed. The normal water-to-cement ratio is 1:7.

4. Step 4: Pouring of Concrete

Fine sand or crushed stone is chosen for thin concrete, whereas coarse aggregate is utilized for thicker concrete.

The aggregate and cement mixture is combined and poured into the existing concrete. A hand trowel or a paver is used to uniformly spread the concrete by pushing it down forcefully.

A bonding glue is used to guarantee that fresh concrete adheres properly to old concrete. To prevent new-laid concrete from wearing out prematurely, a protective coating is provided by spraying curing agents all over the surface, which normally takes seven days to cure.
