Non-Structural Formply: The Unsung Hero of Construction

Throughout my years of exploring DIY projects and home improvements, one material has consistently proven its worth – non-structural formply. Formply, often underappreciated in the world of construction, is a versatile and dependable choice for a wide range of applications. In this article, I want to share my journey and knowledge about this fantastic building material.

What Exactly is Non-Structural Formply?

Non-structural formply, often referred to as “formwork plywood,” is a type of plywood designed for use in formwork systems. Formwork, in the context of construction, refers to the temporary structures used to mold concrete into the desired shape during the pouring and curing process. Non-structural formply is specifically engineered for this purpose.

Key Features of Non-Structural Formply

  • Smooth Surface: Formply is known for its smooth and consistent surface, which is ideal for achieving a high-quality finish on concrete.
  • Reusable: It is designed to be reusable for multiple concrete casting cycles, making it a cost-effective choice for construction projects.
  • Durability: Formply is manufactured to withstand the rigors of construction, including exposure to moisture and pressure from poured concrete.
  • Consistent Thickness: Non-structural formply maintains a consistent thickness, which is crucial for maintaining uniform concrete thickness.

Why I Choose Non-Structural Formply

1. Achieving Quality Concrete Finishes

One of the main reasons I choose non-structural formply is its ability to deliver quality concrete finishes. Its smooth surface ensures that the concrete takes on a pristine appearance, making it suitable for a wide range of applications, from architectural elements to functional construction.

2. Reusability

Formply is designed to be reused multiple times. This not only reduces waste but also makes it a cost-effective option for construction projects that involve multiple concrete pours. As someone who values sustainability and efficiency, this is a significant advantage.

3. Durability

Formply is engineered to withstand the challenging conditions of construction sites, including exposure to moisture. This durability ensures that it can hold up well over time, even with regular use.

4. Consistency

Maintaining a consistent thickness is crucial when it comes to achieving uniform concrete thickness in construction. Formply’s reliability in this regard makes it a valuable choice for ensuring structural integrity.

How to Work with Non-Structural Formply

Working with non-structural formply is a straightforward process. Here’s a step-by-step guide to help you make the most of this versatile material:

1. Gather Your Materials

Before starting your project, make sure you have all the necessary materials and tools. You’ll need non-structural formply sheets, circular saw or jigsaw, measuring tape, screws or formwork fasteners, and safety gear, including goggles and gloves.

2. Measure and Cut

Measure and mark the formply sheets according to your project’s design. Use a circular saw or jigsaw to cut along the marked lines. Ensure precise and straight cuts to maintain the desired form.

3. Assemble and Secure

Assemble the cut pieces into the desired formwork configuration. Use screws or formwork fasteners to secure the formply in place. Pay close attention to ensuring a tight fit to prevent any concrete leakage.

4. Pour and Cure

Once your formwork is set up, you can pour the concrete into the mold. Follow standard concrete pouring and curing procedures. Non-structural formply’s smooth surface ensures that the concrete takes on a clean and even finish.

5. Dismantle and Reuse

After the concrete has cured, carefully dismantle the formwork. Non-structural formply’s reusability means that you can use it for future projects, reducing waste and costs.

FAQs About Non-Structural Formply

1. Is non-structural formply suitable for architectural concrete elements?

Yes, non-structural form ply is suitable for architectural concrete elements, including walls, columns, and decorative features. Its smooth surface helps achieve high-quality finishes.

2. Can non-structural formply be used for curved forms?

Yes, non-structural form ply can be used for curved forms by cutting and shaping it to match the desired curve. Its flexibility allows for a wide range of formwork configurations.

3. How many times can non-structural formply be reused?

The number of times non-structural form ply can be reused depends on factors such as the care taken during use and the concrete mix. With proper handling, it can be used multiple times.

4. Is non-structural formply suitable for DIY projects?

While it’s primarily used in construction, non-structural form ply can be used in DIY projects that involve concrete casting. Its reusability makes it an excellent choice for home improvement projects.

5. Does non-structural formply require any special maintenance?

Non-structural form ply does not require any special maintenance. Simply clean and store it properly after use to ensure it remains in good condition for future projects.

  1. Store Properly: When not in use, store non-structural form ply in a dry, well-ventilated area. Keep it flat and protected from moisture, extreme temperature changes, and direct sunlight.
  2. Protect from Moisture: Non-structural form ply is not designed for exposure to moisture. Avoid allowing it to come into contact with water, as prolonged exposure can lead to warping and delamination. If form ply does get wet, allow it to dry completely before using it to prevent mold or rot.
  3. Inspect for Damage: Before each use, inspect the form ply for any visible damage, such as cracks, delamination, or warping. Do not use damaged plywood, as it can affect the quality and stability of the formwork.
  4. Cleaning: If the form ply becomes dirty, you can clean it with a damp cloth or sponge. Avoid using harsh chemicals that could damage the surface. Allow the form ply to dry thoroughly after cleaning.
  5. Edge Sealing: Sealing the edges of the form ply with a suitable edge sealer or paint can help protect the plywood from moisture infiltration. This is especially important if the edges will be exposed to the elements.


In my journey as a DIY enthusiast, non-structural form ply has emerged as an unsung hero of construction. Its role in achieving high-quality concrete finishes and its reusability have made it an invaluable resource in my projects. Whether I’m casting concrete for architectural elements or functional construction, non-structural formply consistently delivers.

So, if you’re embarking on a construction project that involves concrete casting, consider non-structural form ply as your trusted companion. Its smooth surface, reusability, durability, and consistency ensure that your concrete work turns out just as you envision it.
