Flat Roofs & Podium Decks

Flat Roofs & Podium Decks Issues

The difficulty in the successful waterproofing of flat roofs and podiums lies in the weak spots on the structure, such as seams in the waterproofing membrane, and difficult to waterproof details such as upstands, outlets and penetrations.

The Problems 

Problems can also occur when the waterproofing cannot accommodate fractional movement, which can result in splits and cracks, allowing water ingress. WIDOPAN manufacture a range of cold applied liquid waterproofing systems suitable for all types of flat roof, podium decks, details and repairs.

Polyester, PMMA & PU

Our Polyester, PMMA and PU based resins are at the forefront of waterproofing technology and are characterised by rapid curing times, low temperature application and high flexibility.
Once applied, our systems create a seamless, fully bonded membrane that is permanently elastic and fully reinforced.

Flat Roof Applications

New Builds & Refurbishment

The versatility of WIDOPAN’s cold-applied liquid waterproofing systems, coupled with the range of primers we offer enables them to be applied over virtually all surfaces – meaning our systems are suitable for both roof refurbishment and new construction. 

Existing roof coverings can be fully encapsulated with ease – extending the life of the roof structure and providing a new and robust waterproof membrane. The ability to overlay an existing flat roof without removal of the existing waterproofing means a reduction in costs and disruption on a project.  

With new build applications, our highly flexible, reinforced waterproofing systems are compatible with all modern building materials and as environmental impact and sustainability become important factors in construction, key benefits of the WIDOPAN waterproofing systems - such as root resistance for Green Roofs - make it the perfect choice.

Flat Roof and Podiums

Safe Working Solutions

Traditional waterproofing materials are often hot applied – utilising gas torches, burners and hot air guns.
These installation techniques pose a significant fire risk, and the health & safety concerns mean increased costs with insurance premiums and required permits.

Widopan products and systems are all cold applied, eliminating the risks and costs associated with installations involving hot works.

Our continuous work and development in waterproofing technologies has resulted in a range of solvent & odour free products – providing solutions for sensitive environments and removing the need for additional ventilation.

Zero Falls

Zero falls are often subjected to standing water, or ponding, especially during or following heavy rainfall. Falls of less that 1:80 can lead to an increased risk of deflection and water penetration.

Widopan waterproofing solutions are fully certified for zero falls applications and guaranteed for up to 20 years. Our systems accept continual ponding on the roof without compromise to the waterproofing membrane.

Alongside other system benefits, such as flamefree application, low temperature application and rapid curing, it provides distinct advantages to installers and clients to ensure long-term waterproofing success to the roof.
