Can Plywood Get Wet During Construction?
1. Understanding Plywood and Its Composition
Plywood is a versatile building material commonly used in construction projects. It is made up of thin layers of wood veneer that are glued together, with each layer being positioned perpendicular to the adjacent one. This cross-grain construction gives plywood its strength and durability. The glue used in the manufacturing process is usually waterproof, making plywood resistant to moisture to a certain extent. However, it is essential to note that plywood is not entirely waterproof and can get wet during construction under certain circumstances.
The Composition of Plywood:
Plywood typically consists of three or more layers or “plies” of wood veneer. The wood veneer used can be from hardwood or softwood, depending on the intended application of the plywood. The layers are bonded together using adhesive, often a phenol-formaldehyde resin or urea-formaldehyde resin. The adhesive provides strength and stability to the plywood, allowing it to resist warping, twisting, and splitting. Additionally, manufacturers may treat the plywood with chemicals to enhance its resistance to moisture and decay.
The Cross-Grain Construction:
One of the key features of plywood is its cross-grain construction. Each layer of wood veneer is placed perpendicular to the adjacent one, resulting in a strong and stable panel. This cross-grain construction minimizes the expansion and contraction of the plywood when exposed to changes in temperature and humidity. However, although plywood is designed to withstand moisture to a certain extent, it is not completely impervious to water and can absorb moisture if exposed for prolonged periods.
2. When Can Plywood Get Wet During Construction?
During construction, there are several situations where plywood can potentially be exposed to moisture:
1. Inclement Weather:
One of the most common ways plywood can get wet during construction is through exposure to rain or snow. If left uncovered or unprotected, plywood can absorb water, leading to swelling, warping, and a decrease in its structural integrity. It is crucial to plan construction activities around the weather forecast and protect plywood from direct exposure to moisture during rainy or snowy periods.
2. Improper Storage and Handling:
Another situation where plywood can become wet is during storage and handling. If plywood is stored in an area prone to leaks, or if it comes into contact with standing water, it can absorb moisture. Similarly, if plywood is not properly covered or protected during transportation, it can be exposed to rain or other sources of moisture. It is important to store and handle plywood in a dry environment and protect it from direct contact with water.
3. Construction Delays:
Construction projects often encounter unexpected delays due to various factors, such as permit issues, supply chain disruptions, or changes in design. These delays can expose plywood to moisture for extended periods if proper precautions are not taken. Plywood left exposed to the elements for an extended period can absorb water and lead to damage. It is crucial to cover and protect plywood during construction delays to prevent moisture absorption.
3. The Impact of Wet Plywood on Construction
When plywood gets wet during construction, it can have several negative effects on the overall project:
1. Structural Weakness:
Wet plywood can experience a decrease in strength and structural integrity. The absorption of moisture can cause the plywood to swell and warp, leading to an uneven and unstable construction surface. This compromised structural strength can affect the stability of the entire project and may require additional time and resources to rectify.
2. Mold and Mildew Growth:
Moisture in plywood provides a favorable environment for mold and mildew growth. Mold and mildew can thrive on the surface and within the layers of wet plywood, leading to potential health hazards and aesthetic issues. Mold and mildew growth can be difficult to eliminate and may require the replacement of affected plywood.
3. Decay and Rot:
Prolonged exposure to moisture can lead to the decay and rotting of plywood. Decay occurs when the moisture content of the wood exceeds the threshold where decay-causing organisms can thrive. Rotting plywood becomes structurally unsound and poses risks to the safety of the construction project. In such cases, the affected plywood needs to be replaced promptly.

4. Best Practices for Protecting Plywood from Moisture
To minimize the risk of plywood getting wet during construction and mitigate its negative effects, consider the following best practices:
1. Cover and Store Plywood Properly:
Store plywood in a dry and well-ventilated area, preferably on supports to avoid direct contact with the ground. Cover the stacks of plywood with waterproof tarps or plastic sheets to protect them from rain, snow, and other sources of moisture.
2. Use Temporary Waterproof Barriers:
During construction, utilize temporary waterproof barriers, such as tarps or weather-resistant membranes, to shield the plywood from rain or snow. Ensure that the barriers are properly installed, covering the entire plywood surface and ensuring proper drainage to prevent water pooling.
3. Timely Installation and Sealing:
Install plywood promptly and avoid leaving it exposed for extended periods. Seal the edges and any cutouts in the plywood to prevent moisture infiltration. Use waterproof caulking or appropriate sealants to ensure a tight seal and minimize the risk of water penetration.
5. Regular Inspection and Maintenance
Throughout the construction process, regularly inspect the plywood for any signs of moisture damage, such as swelling, warping, discoloration, or mold growth. Address any issues immediately to prevent further damage and ensure the structural integrity of the project. Regular maintenance of the construction site, including the proper removal of standing water and moisture sources, is crucial in protecting plywood from unnecessary exposure to moisture.
6. Conclusion
While plywood is designed to be resistant to moisture to a certain extent, it can still get wet during construction if not adequately protected. Exposure to moisture can lead to structural weakness, mold and mildew growth, and decay. By following best practices, such as proper storage, temporary waterproof barriers, and timely installation with sealing, plywood can be safeguarded from moisture-related issues. Regular inspection and maintenance are also essential to address any moisture damage promptly. Protecting plywood during construction ensures the longevity and performance of the construction project.
