Can I Build a Brick Wall on Concrete Slab?

Technology plays a vital role in automating multiple construction processes to reduce the overall man-hours. For instance, slab foundations are gaining popularity, especially in off-site construction and in do-it-yourself projects.

If you’re building your house in a remote hilly area or near the beach, you need to look into the possibility of building a brick wall on a concrete slab.

However, is it really possible?

Yes, only if you read the following article to understand the background context and the explained procedure.

Building a Brick Wall on Concrete Slab

Concrete is undoubtedly more challenging than rock. That’s why you need to use the right tools and, most importantly, material to anchor walls on concrete slabs.

Concrete Slab Measurement

The first thing to do is to stretch a measuring tape across the concrete slab and mark the position of the wall ends. 

The next step is to run a chalk snap line between the marks to layout the position of one of the wall’s sides. Furthermore, use the tape measure and pencil to mark each end of the wall’s opposite sides.

Repeat the above process to layout the wall’s seconds, third, and fourth sides. Consequently, you’ll be able to layout a long rectangle representing all four sides of the wall.

By the way, you also need to consider the type of wall to be built on the concrete slab. Moreover, you also need to take into account the size of the slab accordingly.

As an example, consider you have a beach house and you intend to build an exterior wall on a slab that is bigger than the shed. 

It’s quite a tricky construction because a heavy downpour will result in water leakage into the shed. Consequently, water will accumulate under the wall and ultimately, rot the wood.

That’s why an exterior wall should be placed on the slab’s outside edge. In this way, the outer siding laps down and over the slab’s edge. And that’s how you can prevent the water from leaking under the wall’s bottom to the inside of the building.

Marking on Concrete Anchors on the Concrete Slab

Once you have done all the markings on the slab, the next step is to make the location of the concrete anchors on the slab.

However, the spacing requirements depend upon the project; nonetheless, the anchors must rest at the wall’s center. You need to place the anchors at each end with an approximate distance of three feet in between.

Pre-drilling Process

After marking the location of concrete anchors, you can start the drilling process. Now attach the masonry drill bit to the hammer drill and pre-drill concrete anchor holes at each mark. However, the depth of the drilling varies in accordance with the following factors:

  • Size of the anchor
  • The thickness of the wall’s framing lumber

That’s why it’s essential to consult the anchor’s manufacturer’s guidelines for the pre-drilling depth requirements if you are building the wall yourself.

Anchor Installation

This step serves as a make or break point in which you need to install the anchor correctly in pre-drilled holes.

  • First, you need to remove the asher and nut from a concrete anchor.
  • Now, place the anchor’s sleeved end into the pre-drilled hole correctly at a 90-degree angle.
  • Once you position the anchor correctly, you can pound it into the hole using a hammer to secure its position. Moreover, you only need to pound it once since it’s just an initial phase before the final installation.
  • After securing all the anchor positions, you can install the anchors into the pre-drilled holes.

Stud Wall Assembling

After the installation of anchors, you can mark the following wall measurements:

  • Top plate
  • Bottom plate
  • Studs on framing lumber

The next step is to do all the above cutting using a circular saw. Now you can fully assemble stud walls with the help of framing nail guns.

Building Wall on Concrete Slab

Now you have reached the final steps of building a brick wall on a concrete slab. The first thing is to mark the concrete anchors’ location of the wall’s bottom plate’s underside.

The next step is to attach the power drill to a wood-cutting bit and pre-drill the anchor hole via each marked position.

Congratulations, because you are all set to lift and slide the wall over the anchors. However, you should align the wall using a chalk snap line to indicate its position.

Moreover, follow these steps in the sequence mentioned below:

  • Slide a washer over each anchor.
  • Use an adjustable wrench to tighten nuts onto each anchor.

Again, it depends on the type of wall you are building on a concrete slab. Ideally, you should have at least six inches of slab exposure between the start of the soil and the bottom of the siding.

However, it should be perfectly aligned with the slab’s outer side in case of an exterior wall. In this way, you don’t have any space between the wall and the slab to accumulate water.

Summary

  • Draw the wall’s position on the concrete slab using measurement tape.
  • Mark the concrete anchor location with proper spacing.
  • Install the anchor to the pre-drilled hole using a hammer.
  • Measure the length of the wall’s top plate, bottom plate, and studs on framing lumber.
  • Align the location of the concrete anchor to the underside of the wall’s bottom plate.
  • Lift the wall and slide it over the anchors.

Conclusion

You can build a brick wall on a concrete slab keeping in view the wall type, concrete slab depth, and soil type. Knowing the soil type is essential so that you can dimension the concrete slab.

After that, the tricky process is to align the slab with that of the wall. For this purpose, you need to be extra cautious to perform the measurements and markings.

Lastly, keep in view the wall’s alignment with the slab’s outer side. It’s important because you don’t water to seep into the slab or accumulate between the slab and wall.
