Roof Waterproofing

Roof waterproofing is a complex task that requires a clear understanding of the building structure, exposure conditions, and how all elements of the system interact. In addition to constant exposure to water and weather, roofs include numerous details and service elements that must be carefully integrated into the waterproofing system.

Key Considerations for Roof Waterproofing

Every roof has specific characteristics that influence how the waterproofing system should be designed and executed. These include:

roof configuration and parapets
number and type of junctions
presence of mechanical and service equipment
drainage conditions
intended use and exposure of the roof surface

Correct consideration of these factors is essential for long-term waterproofing performance.

Roof Details and Service Elements

Modern roofs commonly include:

HVAC and air-conditioning units
service boxes
solar panel mounts
pipe penetrations
structural supports and fixings

Each of these elements must be correctly integrated into the membrane system to maintain its integrity and durability.

New Construction and Remedial Works

Aquastratum delivers roof waterproofing works for both new construction projects and remedial applications where the waterproofing system requires upgrading or improvement.

In remedial projects, particular attention is given to:

assessing the existing roof structure
identifying critical and high-risk areas
selecting solutions suited to actual site conditions

We regularly work alongside construction and remedial contractors to deliver specialised membrane installation works as part of larger project teams.

Our Approach to Roof Waterproofing

Our work begins with a clear assessment of the roof structure and its technical requirements. We place strong emphasis on:

junction detailing
penetrations and interfaces
compatibility of the membrane system with subsequent layers and finishes

Our primary focus is sheet membrane waterproofing, including bitumen, BUTYNOL, and PVC membrane systems, selected and installed to achieve reliable and predictable outcomes.

Typical Scope of Works

waterproofing of flat and trafficable roofs
membrane installation works within remedial projects
installation of sheet membrane systems
detailing of junctions, penetrations, and interfaces
preparation of surfaces for ongoing use and finishes
