Waterproofing is a crucial aspect of protecting structures from water damage. Whether you’re dealing with a damp basement or constructing a swimming pool, tanking systems offer a reliable solution. This guide explores cementitious and epoxy tanking, their benefits, and how to apply them effectively for long-lasting results.
What is Tanking?
Tanking refers to the process of applying a waterproof barrier to a surface to prevent water ingress. It is commonly used in basements, cellars, walls, and floors to protect against moisture. By creating a watertight seal, tanking helps maintain the structural integrity of buildings while preventing issues like mould and damp.
Cementitious vs Epoxy Tanking: What’s the Difference?
Cementitious Tanking
Cementitious tanking is made from cement-based materials, making it easy to mix and apply with a brush or trowel. It is ideal for below-ground structures, such as basements and retaining walls, where dampness is a concern. Cementitious tanking is cost-effective and resistant to minor cracks, making it a popular choice for residential projects.
Epoxy Tanking
Epoxy tanking uses resin-based materials for superior durability and chemical resistance. It is best suited for areas exposed to high water pressure, such as swimming pools, or environments with harsh chemicals, like industrial facilities. Epoxy tanking requires precise application but offers long-lasting, reliable protection.
Benefits of Cementitious and Epoxy Tanking
Cementitious Tanking Benefits
- Cost-effective and easy to apply.
- Suitable for internal and external surfaces.
- Resistant to damp and minor cracks.
Epoxy Tanking Benefits
- Highly durable and long-lasting.
- Resistant to high-pressure water environments.
- Provides chemical resistance for industrial applications.
Where to Use Cementitious and Epoxy Tanking
Tanking products can be applied in various settings:
- Cementitious Tanking: Basements, cellars, damp-proofing walls, and retaining walls.
- Epoxy Tanking: Swimming pools, water tanks, industrial areas, and underground structures.
The choice between cementitious and epoxy tanking depends on the specific requirements of your project, such as exposure to water pressure or chemicals.
Step-by-Step Guide to Applying Tanking
1. Preparation
Begin by cleaning the surface to remove dirt, debris, and old coatings. For cementitious tanking, the surface should be damp but not wet. For epoxy tanking, ensure the surface is completely dry. Repair any cracks or damage before application.
2. Application
Mix the tanking product according to the manufacturer’s instructions. Apply the first coat evenly using a brush, roller, or sprayer. Allow it to cure as recommended before applying additional coats. Ensure complete coverage for a watertight seal.
3. Curing and Finishing
Follow the curing time specified by the manufacturer for optimal results. Once cured, the tanked surface can be painted or sealed, depending on your project’s requirements.
Common Mistakes to Avoid
- Applying tanking on an improperly prepared surface.
- Skipping essential curing steps.
- Using the wrong product for high-pressure or chemically exposed areas.
- Neglecting safety measures during application.
Maintenance Tips for Tanked Surfaces
Proper maintenance ensures the longevity of tanked surfaces:
- Inspect regularly for cracks or damage.
- Use compatible sealants or coatings for added protection.
- Ensure adequate drainage to minimise water pressure around tanked areas.
Conclusion
Cementitious and epoxy tanking are essential for effective waterproofing in a variety of settings. By understanding their differences and applications, you can choose the right solution for your project and ensure a durable, watertight result. Proper preparation, application, and maintenance are key to maximising the benefits of tanking systems.
