What happens to wood inside concrete?
When wood is embedded inside concrete, the wood will inevitably start to breakdown over time due to moisture and alkalinity levels. This breakdown process, also known as “concrete cancer,” is widely known and leads to damaging aesthetic and structural issues.
Since wood is an organic material, the chemical makeup of the concrete can cause it to break down more quickly. Additionally, the increased levels of moisture and alkalinity within the concrete can further speed up the deterioration process.
Eventually, the wood will begin to rot and swell. As the wood begins to deteriorate, it will breakdown into sawdust, mold, and other organic particles, creating an environment that can lead to further structural damage.
These wood particles within the concrete can also act as axles for the expansion of other structural damages such as cracking and flaking. This condition becomes more severe until the wood is completely rotted away and no longer serves its purpose.
To prevent this from happening, it is important to maintain proper moisture balance and to choose concrete recipes that are well-suited for the application. Additionally, to help mitigate the damage, wood sealers should be used when embedding wood inside concrete.
The sealer acts as a barrier to absorb moisture and alkalinity, thus preventing the wood from decaying. These sealers must be re-applied regularly in order to ensure proper protection.
Can wood be used to reinforce concrete?
Yes, wood can be used to reinforce concrete. Generally, this is done by using plywood or an engineered wood product to create an intricate framework, which acts as an additional structural support system for the concrete.
This approach, often referred to as plywood formwork, makes it possible to reinforce concrete while allowing for flexibility during the design and construction process. Plywood formwork can be used in the construction of retaining walls, foundations and other concrete structures that require added reinforcement.
In addition, the use of wood formwork helps reduce the overall weight of the concrete structure, which leads to cost savings and improved sustainability. Furthermore, as plywood is more lightweight than many other formwork materials, it also reduces labour costs during construction, as the forms are easy to assemble and can be moved quickly and efficiently when needed.

Does concrete stick to wood?
No, concrete does not generally stick to wood, as wood’s surface is too porous for concrete to effectively adhere to it. Concrete will, however, adhere to wood if the wood is treated to make it an ideal surface for the concrete to bind to.
Preparation is usually needed to make sure the wood is smooth and free of dirt, oils, and other contaminants that could prevent the concrete from sticking properly. It is also necessary to apply a bonding agent, such as a liquid concrete bonding agent, over the wood.
This helps to ensure that the concrete will stick to the wood surface and form a strong bond. If not done correctly, the concrete may not stick at all, or it may end up peeling and cracking over time.
How do you adhere concrete to wood?
There are several methods to adhere concrete to wood, such as:
1. Using Thin-Set Mortar – Thin-set mortar is a type of cement-based adhesive that is suitable for both indoor and outdoor installation. To adhere concrete to wood, you need to mix the thin-set with water and then spread a thin layer over the concrete and the wood.
Once the mortar has been applied, you should press the concrete firmly against the wood.
2. Using Liquid Nails – Liquid nails is an all-purpose adhesive that can be used to bond concrete to wood. To use it, apply a generous layer of liquid nails to your wooden surface, then press the concrete firmly against the wood.
Allow the adhesive to dry overnight and the concrete should be securely bonded to the wood.
3. Using Epoxy – Epoxy is an incredibly strong adhesive and is ideal for bonding concrete to wood. To use it, mix the two parts of the epoxy according to the manufacturer’s instructions and then spread a thin layer of it over the wood and the concrete.
Press the concrete firmly against the wood and then leave it to fully cure.
No matter which method you choose, it is important to make sure the surface of the wood and concrete is clean and free from any dirt or debris. This will ensure that your adhesive is able to bond the two materials securely and ensure a strong and lasting bond.
Can you pour self-leveling concrete over wood?
It is not recommended to pour self-leveling concrete over wood due to the high weight of the self-leveling concrete. Wood can easily be crushed and broken depending on the weight of the concrete, so it is not suggested to pour self-leveling concrete over wood.
Additionally, the self-leveling concrete will not properly adhere to the wood, which can cause it to crack, chip and peel over time. Furthermore, if there is any moisture in the wood, it can cause the self-leveling concrete to become discolored and to have an unsatisfactory finish.
Therefore, it is best to avoid pouring self-leveling concrete over wood and use a more suitable substrate such as cement board, concrete board, plywood or a reinforced concrete slab.
Is it OK to set wood in concrete?
Yes, it is OK to set wood in concrete. However, there are several considerations you should make when doing so. First, the type of wood being used should be appropriate for being set in concrete. Softwood, such as pine or cedar, is not recommended, as it will readily absorb moisture and degrade over time.
Hardwoods, such as oak, walnut, or mahogany, are better choices, as they are more resistant to moisture and rot. Additionally, the wood should be properly treated and sealed to provide further protection from moisture, ensuring it remains stable and in good condition for years to come.
It is also important to take the necessary steps to ensure the wood does not come in contact with the concrete itself. For example, a concrete form should be used to create a barrier between the wood and the concrete, preventing any moisture from transference.
This helps keep the wood from warping and swelling due to moisture from the concrete.
Lastly, additional considerations should be taken to ensure the wood remains secure. This can include using additional screws or nails to secure the wood to the concrete form, or even sealing the wood with a waterproof sealant.
By taking the appropriate precautions, it is possible to safely and securely set wood in concrete.
What should I put between wood and concrete?
When joining wood and concrete, it is essential to use materials that can accommodate a wide range of motion, such as expansion, contraction, and differential movement. The core material used to join wood and concrete should provide water shedding, be vapor permeable, and have excellent adhesion and bond integrity.
Common materials used in between wood and concrete are:
• Self-adhesive membrane: This is a good option that can be used to seal and protect the joint, as well as prevent moisture movement. It is easy to install, and can be adhered to the wood and concrete surfaces.
• Reinforced sheet membranes: Reinforced sheet membranes are another option, as they can provide protection from cracking and water ingress. However, they need to be properly sealed and lapped at the edges.
• Caulking: Caulking is a great choice for sealing gaps between wood and concrete. It includes flexible materials such as latex, polyurethane, and silicone. It is often ideal for joints with larger gaps, as it can prevent moisture ingress.
• Mortar: Mortar is another great option that can be used to fill small gaps and voids. It is typically used in between larger joints and is mostly non-staining and easy to clean.
• Polyurethane foam: For large gaps, polyurethane foam can be a good choice. It is applied in liquid form, allowing it to expand and fill the gap between two materials. The foam is quite durable and strong, providing a good adhesion and sealant between the wood and concrete.
What will concrete not stick to?
Concrete typically does not stick to nonporous surfaces, such as metal, plastic, glass, or sealed wood. This is because these materials are not permeable and do not have any pores or openings that the concrete can bond with.
Additionally, concrete has difficulty adhering to other concrete surfaces if the surface has been sealed with an acrylic, polyurethane, or other type of sealer. Lastly, it may not adhere to asphalt and other surfaces that have been oiled or chemically treated.
Will wooden posts rot in concrete?
Yes, wooden posts are susceptible to rot when placed in concrete. Wood is an organic material that breaks down when exposed to certain conditions including moisture and temperature fluctuations, so when it’s trapped in concrete it can’t move with those changes.
The concrete also traps water at the base of the post, which can accelerate the rate of decay. To prevent rotting, the surface of the post should be treated with a coat of preservative before it is set in the concrete.
Sealing all sides also helps reduce moisture-related damage to the post. If possible, trenches should be used rather than concrete when burying posts and the post should be set on a bed of gravel to allow drainage around the post.
Additionally, wooden posts should not be placed directly in earth as the ground can hold moisture against the posts and cause them to rot.
