Bauder LiquiTOP System Cold Applied Roof Waterproofing

The Bauder LiquiTOP System is a cold applied liquid waterproofing based on single-component, moisture triggered polyurethane that incorporates a glass fibre mat reinforcement. This long-lasting, durable and seamless waterproofing is suitable for refurbishment and new build projects. Key attributes of this system type are its versatility for contouring to complicated roof details, waterproofing in constrained areas of access, and around high concentrations of rooftop plant.

Our LiquiTOP System can be applied as a two coat or three coat (LiquiTOP 3COAT System) solution and utilises the latest fast-curing and cross-linking technology to ensure a full bond to a wide variety of substrates and consistency of application for the full period of shelf life.

When to specify...

The Bauder LiquiTOP System is excellent on refurbishment and new build projects particularly where the complexity of the roof involves intricate areas to be detailed that are not easily achieved with a membrane, or the actual working space on the roof is constricted. The compatibility and strong bond achieved over many existing roof systems, combined with a vapour permeability that allows the membrane to breathe and reduce vapour pressure build-up makes the Bauder LiquiTOP system ideal for roof overlays where the existing roof system may contain some moisture and is still securely attached.

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.

Features and benefits

Below is a table of all the features and benefits of Bauder LiquiTOP System Cold Applied Roof Waterproofing.

Features

Benefits

Overlay existing systems
  • Ideal for refurbishment projects
  • Perfect for restricted heights at door sills upstands etc
  • Saves labour time as removal of existing waterproofing may not be necessary
  • If overlay, no material disposal costs or removed system going to landfill
High levels of elasticity
  • Withstands thermal and structural movement
  • Bridges small cracks and gaps
Monolithic membrane, seamless and joint free
  • Blends easily, no prominent joins or laps
  • Low maintenance
  • Aesthetically pleasing
Cold liquid application
  • Contours to roof shape and detailing
  • No hot works during application
  • Reduced health and safety practices for installation
  • Can be used on combustible substrates and details
Low Volatile Organic Compounds (VOC) content
  • The reduction of VOC content in The Bauder LiquiTOP System reduces the amount of volatiles emitted into the environment on application, which is better for the environment as well as the client and contractor.
Reinforced with glass fibre mat
  • Strengthens waterproofing
  • Easily moulded around challenging details
  • Fully embeds into PU layers
Fully bonds to a wide variety of substrates:
  • Suitable in many situations
  • Bonds to most flat roof substrates
Moisture triggered curing to form cross-linked polymeric waterproofing membrane
  • Forms a single fully cross-linked waterproofing system
  • Installation in a variety of weather temperature conditions
  • Tolerant of substrate moisture
Single component
  • No mixing or measuring of materials required making it easier to use on site
Early rain resistance
  • Quickly provides initial waterproofing of building

The Bauder LiquiTOP System can be applied in two coats, and The Bauder LiquiTOP 3COAT System can be applied in three coats, providing you with guarantees of up to 20 and 25 years respectively.
  • Lifecycle expectation and guarantee duration to meet the needs of the client and building.
UV stable throughout
  • Both colours of LiquiTOP PU are UV stable and can be used either way round
  • Improved UV resistance for the whole membrane
Vapour permeable membrane
  • Can overlay existing waterproofing where a small amount of entrapped moisture is present
  • The membrane allows any vapour pressure to dissipate in a controlled fashion
Ability to add more layers at end of the lifecycle
  • Extends lifespan of waterproofing as additional layers can be added at the end of serviceable life
  • Extends life of roof and supports building lifetime
BBA Certified
  • Independently tested and confirmed performance characteristics
Achieves BROOF(t4) when tested in both flat and sloping orientations on insulated and uninsulated systems. The BBA Certificate details the systems tested.
  • Proven external fire performance for flat and sloping roof applications
 

Colours

LiquiTOP PU is available in two colours, either of which can be used as the first/embedment coat or top coat:

Approvals, certification and guarantee

  • BBA Certification - The Bauder LiquiTOP System has been tested and certified by the BBA and carries certificate number 20/5789  which covers The Bauder LiquiTOP System and The Bauder LiquiTOP 3COAT System.
  • External Fire Performance of insulation:
  • BauderPIR Insulation - Within a warm roof waterproofing system BauderPIR insulation is not exposed and is therefore protected through the performance of the cap sheet and achieves the system classification, BROOF(t4), for flat and sloping roofs.
  • BauderGLAS and BauderROCK - These insulants are non-combustible and are used for construction projects requiring additional safety criteria.  
  • Durability - The system incorporates a high-grade 225 g/m² glass fibre mat to provide increased membrane strength, life expectancy and resistance to cracking, whilst on concrete surfaces providing enhanced crack bridging.
  • 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.
  • Bonding Superiority - The Bauder LiquiTOP System delivers superior adhesion between layers as well as to most deck structures or existing waterproofing that requires an overlay solution including concrete, reinforced bitumen membranes (RBM), PVC single ply, liquid applied membranes (LAM), and asphalt.

Environmental credentials 

  • Environmental Product Declarations (EPD) - The Eco Platform accreditation is recognised by the BRE as valid and transferable environmental documentation towards obtaining BREEAM credits within its assessment process for BREEAM UK New Construction 2018. View EPD certificate ►
  • Within our cold applied PU system we have the following EPD certification:
    LiquiTOP Products: EPD-FEI-20180092-IBG1-EN​
    Bitumen Membranes: S-P-00414
    PIR Insulation - Aluminium Facing: EPD-IVP-20140207-IBE1-EN
    Mineral fleece facing: EPD-IVP-20140206-IBE1-EN
  • 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 Bauder 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 securer working environment for the client and contractor. This low-monomer formulation makes The Bauder LiquiTOP System one of the safest and environmentally friendly, single-component moisture-triggered polyurethane waterproofing system products on the market.
  • PIR Insulation - Our BauderPIR insulation holds EPD certification EPD-IVP20140207-IBE1-EN. It has extremely high thermal efficiency and is CFC and HCFC free for zero ODP. As part of our PIR insulation manufacturing process, offcuts and waste are readily recycled and used in the production of hand cleansers and decking materials. The embodied energy of our rigid polyurethane PIR insulation accounts for as little as 4% of the energy the board can save during its serviceable life. The inclusion of insulation when installing new or refurbished roofs plays a significant part in reducing CO2 emissions
