Damp issues can plague many homes, leading to structural damage, health problems, and an overall decrease in property value. One effective method for combating dampness is the application of tanking slurry. In this blog post, we'll explore what tanking slurry is, how it works, and why it's an excellent solution for stopping damp in your property.

What is Tanking Slurry?

Tanking slurry is a waterproof coating made from cement-based substances, designed to prevent water ingress and dampness in buildings. When applied to walls and floors, it forms a barrier that stops water from penetrating the surface, keeping interiors dry and free from moisture-related issues.

How Does Tanking Slurry Work?

The effectiveness of tanking slurry lies in its composition and application. Here’s how it works:

1. Chemical Composition: Tanking slurry is typically made from a blend of cement, aggregates, and chemical modifiers. These components create a dense, impermeable layer when mixed with water and applied to surfaces.

2. Application Process:

   • Surface Preparation: Before applying tanking slurry, the surface must be clean, free of loose material, and ideally dampened to ensure better adhesion.
   • Mixing: The slurry is mixed according to the manufacturer’s instructions, usually involving the addition of water to create a workable paste.
   • Application: Using a brush, roller, or trowel, the slurry is applied in multiple coats to ensure a thorough and even coverage. Each layer needs to dry before the next is applied.
   • Curing: Once applied, the tanking slurry needs time to cure and harden, forming a waterproof barrier that protects against dampness.

3. Waterproofing Mechanism: As the slurry cures, it undergoes a chemical reaction that creates a crystalline structure. This structure blocks the pores in the substrate, preventing water from passing through and thus stopping dampness from penetrating the treated area.

Benefits of Using Tanking Slurry

1. Effective Damp Prevention: Tanking slurry provides a robust and long-lasting barrier against dampness, making it an ideal solution for basements, cellars, and other below-ground structures prone to water ingress.

2. Versatility: It can be applied to various surfaces, including brick, stone, and concrete, making it suitable for a wide range of applications.

3. Cost-Effective: Compared to other damp-proofing methods, tanking slurry is relatively affordable and offers excellent value for money considering its durability and effectiveness.

4. Improved Indoor Environment: By preventing dampness, tanking slurry helps to maintain a healthier indoor environment, reducing the risk of mould growth and associated health problems.

Common Questions About Tanking Slurry

1. Can tanking slurry be applied to all types of surfaces? Tanking slurry is suitable for most masonry surfaces, including brick, stone, and concrete. However, it’s essential to ensure the surface is clean and sound before application.

2. How long does tanking slurry last? When properly applied, tanking slurry can provide long-lasting protection against dampness, often lasting for decades with minimal maintenance.

3. Can I apply tanking slurry myself, or should I hire a professional? While it’s possible to apply tanking slurry as a DIY project, hiring a professional is recommended to ensure correct application and maximum effectiveness.

Conclusion

Tanking slurry is an effective and versatile solution for preventing damp in your home. Its ability to create a waterproof barrier on masonry surfaces makes it ideal for use in basements, cellars, and other areas susceptible to water ingress. By understanding how tanking slurry works and its benefits, you can make an informed decision on how best to protect your property from damp-related issues.
