Bauder LiquiTOP system is ideal for the refurbishment of existing roofs and particularly suited to those that have a high degree of complex detailing, around high concentrations of rooftop plant, and in constrained areas of access. 

It can also be used in roof terrace applications where the system is laid to falls and is protected by slabs or decking on pedestals.

The system can be installed as a two-coat or three-coat (LiquiTOP 3COAT System) solution and fully bonds to the substrate, such as a direct waterproofing overlay to an existing flat roof.

The cold application means hot works are not necessary for the installation of the system making it ideal for many sites, e.g. production facilities where fire safety constraints apply.

• CCPI Verification Number 0007700034/1125 for LiquiTOP Roof System.
• BBA Certification - The LiquiTOP System has been tested and certified by the BBA and carries certificate number 20/5789  which covers The Bauder LiquiTOP System and The LiquiTOP 3COAT System.
• BauderPIR Insulation - Within a warm roof waterproofing system BauderPIR insulation is not exposed and is protected through the performance of the cap sheet and achieves the system classification, B_ROOF(t4), for flat and sloping roofs.

• BauderGLAS and BauderROCK - These insulants are non-combustible and are used for construction projects requiring additional safety criteria.  
• Safety Conscious Installation Technology - The Construction, Design and Management Regulations 2015 place specific duties on designers, contractors and building owners to take fire safety into account throughout a building’s life cycle, making sure that all people on site are protected if a fire does ever occur. The Bauder LiquiTOP System is cold applied and no hot works are required for installation, this eliminates the risk of fire. This installation method means that in refurbishment situations buildings can remain fully operational throughout, with minimal disruption.

Life-cycle costings - 
The flexibility of the LiquiTOP PU is such that it can be overlaid at the end of its service life with the application of an additional layer to extend the lifespan of the roof by a further ten years each time.

Product composition - 
The low-monomer, VOC content in The LiquiTOP System reduces the amount of volatiles emitted into the environment at application to offer a safer and more environmentally conscious alternative than many other liquid waterproofing products on the market, providing a secure working environment for the client and contractor. This low-monomer formulation makes The LiquiTOP System one of the safest and most environmentally friendly, single-component moisture-triggered polyurethane waterproofing system products on the market.
