LiquiTEC Roof System

Our cold applied liquid roof and terrace system, LiquiTEC, is an extremely durable PMMA resin with fast curing times, completely cold applied and suitable for use on most structural substrates. The roof area can be accessed within hours of installation and it delivers a UV stable, seamless waterproof membrane of the highest quality. 

The system can be configured for a cold or warm roof construction and is fully reinforced with a tough polyester fleece for increased membrane strength, life expectancy and resistance to cracking. Within the insulated solution, our self-adhesive DBR 06 elastomeric bitumen membrane is used as both an air and vapour control layer and as the carrier membrane on which the LiquiTEC products are applied.

When to specify...

Apart from the main benefit of being cold applied, LiquiTEC is particularly suited to areas where membrane systems would be impractical due to a high degree of detailing, or when access to install waterproofing is restricted. The system is appropriate for both new build or refurbishment projects onto most substrates and can be used with extensive and intensive green roofs.

Approvals, certification and guarantee

  • Comprehensive range of guarantees for this system.
  • BBA Certificate number 14/5152 LiquiTEC Roof System.
  • Our LiquiTEC Warm Roof System and LiquiBALKON system hold ENV1187 fire classification BROOF (t4) and are verified by the BBA as ‘unrestricted’ and suitable for use on any part of a roof or terrace. An unreinforced balcony system with LiquiPAVE RF has been tested to EN ISO 11925-2 and 9239-1 and satisfied the criteria for Euroclass Bfl-S1 according to EN 13501-1.
  • Bauder LiquiTEC meets FLL guidelines, which is the benchmark test for root resistance in Europe.

Environmental credentials

  • Manufactured under ISO 14001 Environmental Management System.
  • All cold applied liquid products are solvent, isocyanate and halogen free.
  • BRE Green Guide ‘A+’ generic rating, element number 1212530006 when used with warm roof insulation on a profiled steel deck with steel supports.
  • BRE Green Guide ‘C’ generic rating, element number 1212530060 when used with pre-cast concrete hollow slab with screed, inverted insulation with pebble ballast.
  • EDP certification for LiquiTEC products: EPD-DBC-20190116-IBE1-EN. 
  • EDP certification for PU insulation - aluminium facing is EPD-DBC-20190116-IBE1-EN.
  • Insulation within a Warm Roof Construction: the BauderPIR insulation used within the warm roof construction of a cold applied waterproofing system has extremely high thermal efficiency and is CFC and HCFC free. It has zero ODP and a Global Warming Potential of less than 5Kg CO2 - Eq/Kg. 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. With buildings accounting for 50% of the energy consumption in Europe, the inclusion of insulation when installing new or refurbished roofs plays a significant part in reducing CO2 emissions.

Installation and maintenance

The quality and experience of the installing operative is paramount to ensuring a successful project. Bauder approved contractors are the only people fully trained and certified to install our products. They provide the necessary experience that our exceptional guarantee demands.
