General Membrane
General Membrane, based in Italy, specializes in advanced waterproofing and insulation solutions for the construction industry. Their product range includes:
Bituminous Membranes: These are high-performance waterproofing membranes made with APAO, APP, and SBS compounds, offering excellent durability, flexibility, and resistance to weathering.
These products are manufactured in Ceggia, near Venice, in state-of-the-art facilities with a strong emphasis on quality control and production flexibility
Waterproofing materials by General Membrane were born to resist to one of the biggest strengths known by man: Time. They are manufactured thanks to investments in Technology, Research, Development and Quality, which make them excellent for duration and performance.
Frequently Asked Questions
What membrane compounds does General Membrane manufacture?
General Membrane produces polymer-bitumen membranes using APP, SBS and APAO compounds. Each formulation offers a different balance of heat resistance, low-temperature flexibility, movement capability and dimensional stability, so selection should follow the project specification.
Are General Membrane products available for green roofs?
Yes, the range includes membranes specifically designed and tested for resistance to root penetration. Only the named anti-root product and approved complete build-up should be used beneath vegetation.
Can the membranes be installed in different ways?
Depending on the product and system, membranes may be torch applied, self-adhesive, mechanically fixed or used with an approved cold-applied method. The deck, fire-risk controls and manufacturer guidance determine the appropriate installation technique.
What is the difference between a single-layer and two-layer system?
A single-layer membrane is designed to provide the primary waterproofing in one specified layer, while a two-layer system uses an underlay and capsheet with staggered joints. The correct arrangement depends on certification, substrate, exposure, roof use and warranty requirements.
How should service life be described?
Expected durability should be taken from the certification and warranty for the selected system. It is not accurate to assign one lifespan to every APP, SBS or APAO membrane, because reinforcement, thickness, surface finish, exposure and installation all affect performance.
