Screed mesh reinforcement

Hey everyone, welcome back to my channel! Today, we’re diving into the world of reinforcing mesh for screed. Whether you’re a seasoned builder or just starting out, understanding the different types and features of reinforcing mesh is crucial for achieving a strong and durable floor.

In this video, we’ll explore the various types of reinforcing mesh available, including their material composition, weight, and mesh size. We’ll also delve into the key features to consider when choosing the right mesh for your project, such as tensile strength, flexibility, and corrosion resistance.

So, if you’re ready to learn everything you need to know about reinforcing mesh for screed, stick around! We’ll cover everything from the basics to more advanced concepts, ensuring you have the knowledge to make informed decisions for your next project. Let’s get started!

The primary function of reinforcing mesh in screed is to prevent cracking caused by shrinkage and thermal expansion. It also improves the overall strength and durability of the screed, making it more resistant to damage from impact and heavy loads.

There are two main types of reinforcing mesh: welded wire mesh and expanded metal mesh.

Welded wire mesh is made from steel wires that are welded together at the intersections. It is available in various sizes and thicknesses, with the most common size being 100x100mm. The thickness of the wire typically ranges from 3mm to 5mm.

Expanded metal mesh is made from a single sheet of metal that is cut and stretched to create a diamond-shaped pattern. It is generally lighter than welded wire mesh and is often used in applications where weight is a concern.

The choice of reinforcing mesh depends on several factors, including the thickness of the screed, the expected load, and the desired level of crack resistance. For thin screeds (less than 50mm), a lighter mesh such as expanded metal mesh may be sufficient. For thicker screeds or those subject to heavy loads, a heavier welded wire mesh is recommended.

The size of the mesh is also important. A smaller mesh size will provide more reinforcement, but it will also be more expensive. The most common size for screed reinforcement is 100x100mm, but other sizes are available.

The weight of the mesh is another factor to consider. A heavier mesh will be more expensive, but it will also provide more reinforcement. The weight of the mesh is typically measured in kilograms per square meter (kg/m2).

The rate of reinforcing mesh size one hundred by one hundred weight square meter in the estimate will vary depending on the thickness of the screed and the expected load. However, a general guideline is to use 1kg of mesh per square meter of screed.

The use of reinforcing mesh in screed is governed by building codes and standards. In Russia, the relevant standard is SNiP two.03.13-eighty-eight “Floors”. This standard specifies the minimum amount of reinforcement required for different types of screeds.

Reinforcing mesh is an essential component of screed, providing crack resistance, strength, and durability. The choice of mesh type, size, and weight should be based on the specific requirements of the project. By following the guidelines provided in this video, you can ensure that your screed is properly reinforced and will perform well for many years to come.

When is reinforcing mesh needed?

• When the screed is thicker than 5 cm (2 inches)
• When the screed is subjected to heavy loads, such as in garages or workshops
• When the screed is laid on a weak subfloor, such as timber or chipboard
• When the screed is laid over underfloor heating

Necessary tools

• Tape measure
• Metal shears
• Utility knife
• Trowel
• Gloves

Important nuances

• The size of the reinforcing mesh should be chosen based on the thickness of the screed and the expected load.
• The mesh should be laid flat on the subfloor and overlapped by at least 10 cm (4 inches) at all joints.
• The mesh should be fixed to the subfloor using nails or staples.
• The screed should be poured over the mesh and leveled using a trowel.

The rate of reinforcing mesh size one hundred by one hundred weight square meter in the estimate

The rate of reinforcing mesh size one hundred by one hundred weight square meter in the estimate will vary depending on the thickness of the screed and the expected load. However, a general rule of thumb is to use 1 kg of mesh per square meter of screed.

Reinforcement according to SNiP

The Russian building code SNiP two.03.13-eighty-eight specifies the requirements for reinforcing mesh in screeds. According to SNiP, the mesh should be made of steel wire with a diameter of at least three mm (0.12 inches) and a mesh size of no more than one hundred by one hundred mm (four by four inches). The mesh should be laid in a single layer and overlapped by at least ten cm (four inches) at all joints.

Additional tips

• When laying the mesh, make sure that it is not touching the walls or any other objects.
• If you are using underfloor heating, make sure that the mesh is not in direct contact with the heating pipes.
• Allow the screed to dry completely before walking on it or placing any furniture on it.

Conclusion

Reinforcing mesh is an important part of any screed installation. By following the tips above, you can ensure that your screed is strong and durable.
