Application versatility
Certified for warm, cold, green, inverted, zero-fall and protected roof specifications.
Why specify Liqui-Zero?
Zero-flame application
Cold-applied installation eliminates the need for naked flames, making the system suitable for projects where hot works are restricted or undesirable.
Solvent-free
A solvent-free formulation supports specification on projects where installation methodology and site conditions require alternative waterproofing solutions.
Low odour
The low odour formulation allows installation in occupied and operational buildings, helping minimise disruption to building users and daily activities.
Sensitive environments
Well suited to healthcare, food production, education, and other sensitive environments where installation constraints influence the specification.
Liqui-Zero Odourless Zero Solvent Waterproofing System Build-Up
As an odourless zero solvent waterproofing system, Liqui-Zero applies with zero-flame installation and no VOC emissions, making it suitable for occupied buildings where fumes, naked flame, or disruption to daily operations cannot be tolerated. The four-layer build-up, reinforced with GarMat 450, delivers long-term watertight performance while meeting the strict environmental and safety requirements of healthcare, education, and food production facilities. Available with a BBA Agrément certified guarantee of up to 20 years, Liqui-Zero gives specifiers a proven, low-disruption solution for the most sensitive live environments.
