Introduction
Water damage is one of the most common and costly problems in buildings. When water penetrates concrete or masonry, it can cause cracks, corrosion of reinforcement, mold growth, and structural deterioration. Left unaddressed, these issues can lead to expensive repairs and reduce the lifespan of the building. Proper waterproofing is essential for protecting structures, maintaining their integrity, and extending service life. Costar Conseal 250 is a high-performance waterproofing coating designed to create a seamless, durable layer that shields buildings from moisture-related damage.
What Is Costar Conseal 250?
Costar Conseal 250 is an advanced waterproofing coating that forms a continuous, impermeable layer when applied to prepared surfaces. It adheres strongly to concrete, masonry, and other substrates, preventing water ingress and protecting the structural integrity of buildings. Unlike traditional sheet membranes, it eliminates joints and overlaps, which are common points of failure, ensuring a consistent level of protection throughout the treated area.
Key Benefits of Costar Conseal 250
Seamless Waterproofing Layer
A major advantage of Costar Conseal 250 is its ability to create a seamless waterproofing layer. This eliminates weak points that can occur in traditional membranes, such as seams and joints. A continuous layer reduces the risk of leaks, provides uniform coverage, and enhances the long-term durability of the structure.
Long-Term Service Life
Costar Conseal 250 is designed for long-lasting performance. When applied correctly, it can provide up to 25 years of effective waterproofing. Its high-quality formulation ensures resistance to environmental stress, UV exposure, and water penetration, making it a reliable choice for both new construction and refurbishment projects.
Structural Protection
Water penetration can lead to a variety of structural problems, including concrete deterioration, reinforcement corrosion, surface cracking, and damp interiors. By preventing water ingress, Costar Conseal 250 helps reduce maintenance costs, extends the lifespan of the building, and maintains the structural integrity of critical components.
Compatibility with Other Systems
For projects requiring extended durability, Costar Conseal 250 can be used in combination with Costar Conseal 270 polyurethane waterproofing membrane. This combined system can achieve a service life of up to 35 years, providing maximum protection for high-value or critical infrastructure projects.
Typical Applications
Costar Conseal 250 is versatile and suitable for a wide range of construction and refurbishment applications. Typical uses include:
- Roof slabs and podium decks
- Basements and substructures

- Wet areas such as bathrooms and kitchens
- Concrete and masonry surfaces requiring long-term protection
Its seamless application makes it especially valuable for areas exposed to continuous water contact or high rainfall.
Application Process
The effectiveness of Costar Conseal 250 depends on proper surface preparation and application. Key steps include:
- Surface Cleaning: Remove dust, dirt, oils, and loose particles.
- Priming: Apply a compatible primer if required to enhance adhesion.
- Application: Spread the coating evenly using a brush, roller, or spray, ensuring full coverage.
- Curing: Allow the coating to cure properly to achieve its full waterproofing potential.
- Inspection: Check for uniform coverage and repair any thin spots or defects.
Following these steps ensures optimal performance and long-term durability.
