Liquid Applied Membranes (LAM)
Cold applied liquid waterproofing systems provide a seamless, fully bonded solution for flat roofs and complex detailing areas. T & T Roofing Limited has extensive experience specifying and installing liquid-applied membranes across commercial, residential, and public-sector projects.
Applied without the use of heat or flames, liquid-applied membranes are particularly well suited to projects where safety, access constraints, or occupied buildings are key considerations. Once applied, the system cures to form a continuous, flexible membrane, delivering reliable long-term protection against water ingress and weathering.
Applications & System Suitability
Cold applied liquid waterproofing systems are suitable for use in both warm and cold roof constructions and are particularly effective on roofs with complex geometry and detailing. Typical applications include:
- Roofs with multiple penetrations and interfaces
- Balconies and walkways
- Refurbishment and overlay works
- Areas where joint-free waterproofing is critical
The seamless nature of liquid-applied systems eliminates laps and joints, reducing potential weak points while accommodating thermal movement and structural tolerance.

Safety, Access & Occupied Environments
As no heat or naked flames are required during installation, liquid-applied membranes offer clear advantages on sensitive or live sites. Where required, low-odour or odour-free systems can be specified, making them suitable for use in schools, healthcare facilities, residential buildings, and occupied commercial premises.
Our teams are experienced in planning and delivering works in constrained and occupied environments, with careful consideration given to access, sequencing, and protection of building users.

Compliance, Installation & Quality
All cold applied liquid waterproofing systems are installed in accordance with current UK building regulations, fire safety requirements, and manufacturer guidelines. Works are carried out by fully trained operatives, with appropriate supervision and quality controls in place throughout the installation process.

Our Approach
From initial survey and system selection through to installation and completion, we deliver a structured and professional service focused on compliance, safety, and long-term performance. Early review of substrates, detailing, and interfaces ensures the most appropriate system is selected and integrated effectively into the overall roofing package.
