Attaching wood to concrete is a common construction practice to secure wooden materials to concrete surfaces. This is important because it ensures the wooden structure is firmly anchored and does not shift or move over time.

Choosing the right type of anchor is also crucial for a successful attachment. The anchor must be strong enough to hold the weight of the wooden structure and must be designed to work with both the concrete surface and the type of wood being used.

If you’re curious about how to attach wood to concrete, we’re here to help. Read on to learn the steps of attaching wood to concrete and why you may need to do so.

Why People Attach Wood to Concrete

Before we get started, why bother attaching wood to concrete? Is this purely a strategy for construction, or are there other reasons to do so? Here are the four main reasons why people attach wood to concrete.

Building Structures

The first and most common answer is building structures. Wood and concrete are two of the most used resources in construction. The world uses roughly 30 billion tonnes of concrete annually, making it a nearly-ubiquitous material.

During construction, there’s a high chance you’ll need your wood to attach to concrete. Knowing how to do so effectively is crucial.

Poor construction methods can lead to a weathered structure, failed construction, or severe safety hazards. You need to understand the project ahead of time to avoid shoddy work.

Home Improvement Projects

Another reason for needing to attach wood to concrete is for home improvement projects. These include simple bathroom renovations to redesigning your living room.

During this process, you may need to attach wood to concrete. Knowing the different methods of doing so can help!

For example, maybe you’re building a deck or adding a patio to your home. Will your method of attaching wood to concrete be the same in this situation as it would in any other? Or will an exposed outdoor surface require special care?

Knowing how to attach wood to concrete can help you make the right choice!

Decorative Purposes

Not every use for this skill is centered around construction. You may find yourself decorating your new home and needing to attach wood to concrete. Trying to attach a wooden trim or molding to a wall made of concrete can help with a decorative flair.

This reason is most common outdoors. Trying to attach a wood sign to the concrete wall of your home is a frustrating endeavor. Knowing the different methods can help you pick the best way. This skill can help your construction be more reliable and of higher quality.

Many find this especially useful during the holidays! Attaching an anchor outdoors can help you rotate your decorations with the seasons and holidays.

Safety Purposes

Finally, you may need to attach wood to concrete for safety purposes. An example is attaching a wooden handrail to concrete stairs or walls.

If you don’t secure the wood to the concrete, your handrail (or other structure) won’t be stable. This can lead to the structure breaking off when someone needs it most.

When it comes to safety, knowing what you’re doing is crucial. Use the best practices for your task to avoid accidentally creating a safety hazard.

Types of Anchors

Now that we know why you may want to attach wood to concrete, how will you go about it? There are several styles of anchors that you should know about. These anchors are used for different needs, settings, environments, aesthetics, etc.

Wedge anchors are one of the most common anchors for concrete. These anchors are great for wood into concrete and attaching nearly anything to concrete. 

They’re easy to use but cannot anchor into brick or block, requiring a flat surface. The base material must be solid concrete. Once applied, a wedge anchor is considered the strongest.

Sleeve anchors come in all shapes and sizes and are perfect for concrete. They can hold a heavy load, but wedge anchors are often more stable. 

On the other hand, sleeve anchors can adhere to any concrete style, including blocks or bricks. This makes them slightly more versatile.

Concrete screws are arguably the simplest. As a result, they’re also the cheapest but aren’t seen to be as stable as wedge or sleeve anchors. Concrete screws are great for most general applications but you may need several for safe and stable construction.


Now that you’ve chosen your anchor, preparing the area is important. You can’t pick up a screw and a drill and begin right away. The concrete needs a few steps first.

To start, prepare the concrete surface by flattening it and scouring away imperfections. Using a wire brush is a good way to get stubborn bits of dirt off. You can also use a vacuum cleaner.

Once the area is prepared, ensure you have all the necessary materials. This includes your anchors, the wood you’re using, your tools, and anything else.

It’s safest to work in pairs or more. That way, someone can hold the wood steady while you attach the anchor. If not, do your best to stay out from under the wood in case it falls. 

Marking and Drilling

Let’s look into step by step process of marking and drilling 

  • Mark the spot where you’ll be drilling. Use a measuring tape and pencil to mark the appropriate drilling points. Remember to double-check your measurements before proceeding.
  • Drill a hole for the anchor. Use a hammer drill and the correct size of a drill bit to create the holes in the concrete. Make sure to drill deep enough to accommodate the length of the anchor.
  • Blow away any concrete dust. Use a blower or brush to remove any concrete dust from the holes.
  • Insert the anchor into the hole. Tap the anchor into the hole with a hammer until it is flush with the surface of the concrete.
  • Screw in the wood screw. Use a screwdriver or drill to insert the wood screw into the anchor. Make sure the screw is tight and secure.

Inserting the Anchors

step-by-step instructions for inserting anchors into concrete:

  • Bore holes in the concrete where you want to insert the anchors.
  • If you’re using concrete screws, skip this step and move on to the next step. If you’re using other anchors, continue to the next step.
  • Choose the appropriate style of anchor based on your needs and the application. Wedges and sleeve anchors have different application methods, so make sure you understand the instructions for your chosen anchor style.
  • Insert the anchor into the hole you’ve bored in the concrete. Make sure the anchor is flush with the surface of the concrete. If the anchor has room to wiggle, it may not be securely anchored and could fail underweight.
  • Apply firm pressure to ensure the anchor is securely in place. If you can’t get the anchor flush with the surface of the concrete, you may need to use a different size anchor or drive it deeper.

Attaching the Wood

With your anchor safely and securely set, you can attach the wood to the anchor. You can use screws or bolts to attach the wood to the anchors for this step.

If you’re using concrete screws, you may be screwing directly from the wood into the concrete. This step is as simple as using any other screw. Just make sure that concrete screws are the right tool for the job!

Otherwise, make sure you’re using long enough screws or bolts to provide a secure attachment. If this attachment isn’t secure, your wood could fall off of the anchor. This can ruin a decoration or significantly threaten the integrity of your construction.

Finishing the Project

Now that you’ve anchored your wood let us take a look at the steps to finish this project:

  • Cut and prepare the wood boards, sand, and paint or stain as desired.
  • Mark where you want to attach the wood boards to the concrete.
  • Drill pilot holes into the concrete and insert concrete screws or anchors.
  • Attach the wood boards to the concrete screws or anchors using a drill.
  • Inspect the wood for missed spots or imperfections, and touch up as necessary.

Safety Precautions

Part of your preparation includes your safety precautions. What you wear, when you work, and what you use are all crucial!

In terms of clothing, make sure you’re wearing appropriate gear. Long pants and sleeves that don’t interfere with your work are suggested. We also recommend thick gloves and boots to prevent scratches or injury. A dust mask is ideal, as drilling into concrete can cause airborne dust.

Find the right tool for the job. Using screws or bolts that are too small may make it difficult to fasten the wood. Doing so can lead to structural instability or heavy wood falling on you.

Finally, try not to work alone if you can help it. Having someone with you can help make things safer, as well as make a response faster if someone is injured.

Work during the day if you can. Working in clear light is more effective and safer than late at night when you’re tired!

Final Thoughts

Attaching wood to concrete is important for construction, safety improvements, and decoration. You have the choice of several anchors to find something that matches your project. Do your best to work safely and with others to prevent injury.
