Method of Statement of roof combo waterproofing works with step by step details and procedure.

Roof combo waterproofing is a type of waterproofing system that combines different waterproofing materials and methods to provide comprehensive protection to a roof. It typically includes a combination of roof coating, membrane, and other materials to create a multi-layered system that provides increased protection against water penetration.

The method statement for roof combo waterproofing works includes the following steps:

1. Preparation: Before starting the waterproofing work, the site should be cleared and the roof should be prepared. The necessary materials, tools, and equipment should be on site.
2. Surface Preparation: The surface to be waterproofed should be cleaned and made smooth to ensure a proper bond between the surface and the waterproofing material. Any cracks or gaps should be filled and the surface should be checked for level.
3. Priming: A primer should be applied to the surface to ensure a proper bond between the surface and the waterproofing material.
4. Application of Membrane: A waterproof membrane should be applied to the surface in accordance with the manufacturer’s instructions. The membrane should be applied evenly and any air pockets should be removed.
5. Application of Roof Coating: A roof coating should be applied over the membrane to provide additional protection against water penetration.
6. Sealing the Joints: The joints between the roof coating and the membrane should be sealed to prevent water from penetrating the surface.
7. Installation of Drainage System: A drainage system should be installed to ensure that water is effectively drained away from the roof surface.
8. Testing the Waterproofing: The waterproofing system should be tested by applying water to the surface and checking for any leaks. Any leaks should be repaired.
9. Inspection: After the waterproofing work is complete, the surface should be inspected to ensure that it meets the specified requirements and that there are no defects.

It is important to follow these steps carefully and in the correct order to ensure the proper application of the waterproofing system to the roof. It is also recommended to have a competent person supervise the waterproofing work and to ensure that all workers follow proper safety procedures.
