Roof completed with Hot Melt waterproofing system

Hot Melt Roof System

Bauder Hot Melt waterproofing system is designed for use in inverted or buried roof scenarios.

Hot Melt Roof System

Bauder Bakor Hot Melt System achieves a CCPI mark which recognises that any claims made about it have been independently assessed across 11 clauses, providing greater clarity by offering improved product information. This gives specifiers confidence in the knowledge that they will have unambiguous information when deciding which of our systems is best for their new build or refurbishment project.

Bauder Hot Melt CCPi

When to specify

Bauder Hot Melt waterproofing system is a hot applied polymer modified bitumen waterproofing applied in two layers with a polyester reinforcement. It is capable of a 100% bond to the approved surfaces it is applied. 

Hot melt structural waterproofing is particularly advantageous for protected, inverted, or buried roofs such as biosolar roofs, blue roofs, green roofs, paved, terraces, podiums, plazas and car parks. The solution is primarily for new build projects. 

Due to its composition, it remains in a live state, giving it the strength and flexibility to cope with the stresses and strains of the building it protects for the length of time it remains.

Plus points
  • Compatible with various landscaping finishes including hard landscaping, green roofs, blue roofs and biosolar solutions.
  • Range of insulations including non-combustible options.
  • Seamless application provides monolithic waterproofing.
  • Full adhesion to deck substrate.

Flame-Free detailing methods

Our flame-free detail design specifically delivers secure safe application techniques in the vicinity of combustible construction materials located on or connected to, the roof. This includes timber substrates or upstands; abutments to cladding, roof tiles, slates or thatch; or even debris such as dry leaf material that is at risk of ignition. 

Why clients choose us

Customers choose us because of the way in which we do business, our robust advice on the right system, and our approach to delivering projects. We work alongside clients to deliver the best solution for a building from our broad portfolio of systems. 

We assist you with the design of the detailing, writing the specifications for the flat roof solution, and recommend suitable approved contractors to tender for the project.

The service is without charge, and we work with you to ensure your roof specification meets all your needs and that of the building.
