Terrace and roof joint waterproofing is a crucial service to prevent water leakage and damage in buildings. This service involves applying various waterproofing techniques and materials to ensure that water does not seep through the roof or terrace joints, which can cause structural damage, mold growth, and other issues. Here's an overview of what this service typically involves:
Types of Waterproofing Techniques
-
Membrane Waterproofing:
- Sheet Membranes: These include bituminous, PVC, or TPO sheets applied over the surface.
- Liquid Membranes: These are applied in liquid form and then cure to form a seamless waterproof layer.
-
Cementitious Waterproofing:
- Uses cement-based products to create a waterproof barrier. It's often used for wet areas such as bathrooms but can also be effective for roofs and terraces.
-
Polyurethane Waterproofing:
- A highly flexible and durable waterproofing method that involves applying a polyurethane liquid membrane. It’s particularly effective for areas with high exposure to sunlight and varying temperatures.
-
Bituminous Coating:
- Also known as asphalt coating, this method involves applying a bitumen-based substance. It's durable and resistant to water penetration.
-
Injection Grouting:
- Used for sealing cracks and joints by injecting specialized grouts that expand to fill gaps and prevent water ingress.
