Protecting Screw Piles from Corrosion

Screw piles are used in construction to create a reliable foundation. However, in high-humidity and aggressive environments, they are susceptible to corrosion. To ensure the durability and reliability of the structure, it is important to select the right corrosion protection material.

Why Corrosion is Dangerous for Screw Piles

Corrosion is a process of metal deterioration that can lead to the following consequences:

• Reduced pile strength.

• Increased risk of foundation subsidence.

• Increased maintenance and repair costs.

• Reduced service life of the structure.

What Materials are Suitable for Protecting Screw Piles

There are several methods for protecting screw piles from corrosion. Let's take a closer look.

1. Primer

Primer is used to prepare the surface before applying other protective coatings. It helps improve adhesion and provides moisture protection. We recommend using:

• Anti-corrosion primers based on alkyd resins.

• Primers based on epoxy resins.

2. Paint

Painting is one of the most common methods of protection. Suitable paints for screw piles include:

• Anti-corrosion paints containing zinc.

• Polyurethane and epoxy paints, which provide excellent moisture protection.

3. Zinc Coating

Zinc coating is created by hot-dip galvanizing. It forms a layer on the surface that protects the metal from moisture and oxygen.

4. Polymer Coatings

Polymer coatings provide a high degree of corrosion protection. They are resistant to chemical influences and mechanical damage.

5. Waterproofing

Waterproofing helps prevent moisture from penetrating metal structural elements. Waterproofing materials can be used in combination with other protective coatings.

Step-by-step instructions for protecting screw piles

To effectively protect screw piles, follow these instructions:

1. Clean the surface of dirt, rust, and old coatings.

2. Apply an anti-corrosion primer. 3. Allow the primer to dry according to the manufacturer's instructions.

4. Apply the first coat of anti-corrosion paint.

5. Once the paint has dried, apply a second coat.

6. If necessary, add a polymer coating for additional protection.

Tips for Caring for Screw Piles

Regular maintenance of screw piles will help extend their service life:

• Visually inspect for rust and damage.

• Renew protective coatings periodically.

• Remove small debris and dirt to prevent moisture accumulation.

Proper protection of screw piles from corrosion is the key to the longevity and reliability of your foundation. The use of anti-corrosion materials such as primers, paints, and polymer coatings will significantly reduce the risk of damage and extend the life of the structure.
