LiquiTOP System
When to specify...
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.
LiquiTOP 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 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.
Key Features
■□ Suitable to existing overlay systems.
■□ High levels of elasticity.
■□ Monolithic membrane; seamless and joint free.
■□ Cold liquid application.
■□ Low volatile organic compounds (VOC content.
■□ Reinforced with glass fibre mat.
■□ Fully bonds to a wide variety of substrates.
■□ Moisture triggered curling to form cross-linked polymeric waterproofing membrane.
■□ Single component.
■□ Early rain resistance.
■□ LiuiTOP can be applied in two coats and LiquiTOP 3COAT can be applied in three coats, providing you with guarantees
of up to 20 and 25 years respectively.
■□ UB stable throughout.
■□ Vapour permeable membrane.
■□ Ability to add more layers at the end of the lifecycle.
■□ BBA certified.
■□ Achieves BROOF(t4) when tested in both flat and sloping orientations on insulated and uninsulated systems.
Benefits
■□ Perfect for restricted heights at door sills upstands etc.
■□ Withstands thermal and structural movement.
■□ Forms a single fully cross-linked waterproofing system, bridges small cracks and gaps, blends easily, no prominent
joins or laps and contours to roof shape and detailing.
■□ No hot works during application therefore reduced health and safety practices for installation.
■□ Can be used on combustible substrates and details.
■□ The reduction of VOC content in The 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.
■□ Strengthens waterproofing.
■□ Installation in a variety of weather temperature conditions.
■□ Tolerant of substrate moisture.
■□ Quickly provides initial waterproofing of building.
■□ Both colours of LiquiTOP PU are UV stable and can be used either way round.
■□ The membrane allows any vapour pressure to dissipate in a controlled fashion.
■□ Extends lifespan of waterproofing as additional layers can be added at the end of serviceable life.

Approvals, certification and guarantee
■□ 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.
■□ 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.
■□ 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 securer working environment for the client and
contractor. This low-monomer formulation makes The 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. 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.
