Sealing and Waterproofing a Balcony and Terrace Floor

Sealing your concrete floors requires a high-quality and waterproof sealant that can withstand weather fluctuations and wet conditions. If you don’t seal your terrace or balcony floor, you’re more likely to see cracks developing. This is due to excess moisture damage that has found its way into the concrete. This can then lead to additional damage such as etches and frustrating cracks.

Why does concrete crack?

Concrete is an extremely porous material. It tends to absorb water and moisture into its core. However, this doesn’t cause any serious issues until you start to notice its effects on the surface. This is especially a concern during the winter months or in countries that experience hectic weather conditions. Ice, rain and snow can damage your balcony and terrace floors. This weakens the structure of the concrete and encouraging cracks of all sizes to develop on the surface. If left untreated, those cracks can worsen over time and enlarge.

Waterproofing your Concrete Floors

When water freezes, it expands. This puts pressure on the concrete which is why cracks form on the surface. The only way to really tackle this problem is to waterproof your concrete floors using a waterproof sealant such as C-TEC’s WT1. This strong sealant is perfect for sealing terraces and balconies because it fills and repairs existing cracks whilst helping to prevent future cracks from appearing. WT1 acts as a much-needed replacement for bitumen based roof membranes.

WT1 combines the power of polymer and polyurethane to create a phenomenal product that provides 100% protection from moisture, water, dampness, ice and snow. It can withstand harsh and cool temperatures and serious weather conditions without compromising the integrity and strength of its initial bond. Application is easy thanks to its smooth nature. You can brush or spread it onto the surface of your concrete floor on the terrace or balcony. It will instantly begin to seal the concrete and stop any moisture from penetrating through to the surface of the concrete.

In addition to adhering to concrete, WT1 also creates a formidable bond to other difficult materials. This includes brick, metal, stone, concrete and lead. It is often used to seal and waterproof flat and sloping roofs. However, it can also be used to tank wet walls.
