The MAPEPLAN T M waterproofing system comprises a UVstable and weather-resistant TPO/FPO flexible polyolefin waterproofing membrane featuring a mechanically very strong internal polyester mesh carrier specifically designed and manufactured for fully exposed membrane systems, secured with a mechanical fastening system. Its advantages are:
Loose-laid system with mechanical fastening system
The loose-laid system used for all layers in the roof build-up offers the advantage of being able to absorb the substrate’s movements and expansions without them affecting the waterproofing membrane, which can slide accordingly. Consequently, splitting, cracking or any other defects that might occur in the cast concrete substrate cannot damage the waterproofing membrane.
Loose laying also allows checking the waterproofing membrane’s seams and surfaces using the “tracer gas” system, which is also used to detect leaks. Securing the waterproofing membrane with a mechanical fastening system has the advantage of fixing the waterproofing membrane safely directly to the load-bearing structure underneath. What enables the membrane to withstand negative wind pressure is actually the specific mechanical fixing system, which is calculated and sized to meet Eurocode requirements based on actual job conditions, such as:
- Building height and shape
- Positioning, location
- Type of substrate
- Type of waterproofing membrane and carrier
- Design wind speed.
Compliance with harmonized standards
The MAPEPLAN T M waterproofing membranes have been manufactured and certified to meet the European harmonized standard EN 13956; MAPEPLAN T M can contribute points to obtain the LEED (Leadership in Energy and Environmental Design) certification.
“Multi-extrusion coating” production process
MAPEPLAN T M membranes are manufactured in a modern, technologically advanced and environmentally friendly “multiextrusion coating” plant. This innovative production system allows the TPO/FPO synthetic matrix to be applied directly and at the same time to both faces of the polyester mesh carrier in one go, thus ensuring that it is incorporated perfectly in the membrane’s structure.
This special production process means MAPEPLAN T M membranes are not prone to delamination problems, as they qualify as single-ply membranes that offer excellent resistance to foreseeable (physical, chemical, thermal) stress.
MAPEPLAN T M is an innovative waterproofing membrane formulated without plasticizers or volatile substances.
The MAPEPLAN T M membrane gets its flexibility from the special chemical structure of its polymer component: the element that makes it so flexible is in the molecular chain and is “chemically bonded” to it. This chemical bond is very strong and difficult to separate, which makes the membrane’s inherent qualities last longer, with higher resistance to aggressive substances, as well as improved weathering resistance and resistance to microorganisms and bacteria.
Dimensional stability is ensured by the internal polyester mesh carrier and by the “multi-extrusion coating” production process.
Highly eco-friendly with low environmental impact
MAPEPLAN T M has impressive green credentials since it is free from plasticizers and volatile substances and does not contain substances that are dangerous or harmful to people or the environment. The modern and technologically advanced production system has been designed and built to deliver the lowest possible environmental impact. This low environmental impact is guaranteed during all stages of the membrane’s life cycle: manufacture, transport, installation, service life, end-of-life disposal. Once the waterproofing membrane reaches the end of its life cycle, it can be removed and recycled/reused to produce new raw material.
Smart White surface colouring - signal layer
MAPEPLAN T M has a special white top layer, which gives the product its excellent solar reflectivity and reduces roof surface temperature by over 50% compared to a dark/black-coloured roof, which has clear benefits in terms of comfort due to the building’s lower indoor temperature. The different colour on the membrane’s surface also has the advantage of acting as a signal layer, highlighting any accidental mechanical damage or surface scratching resulting from works carried out once the membrane has been laid.
Thermally welded seams
The MAPEPLAN T M waterproofing membranes are thermoplastic plastomers, which means they have excellent weldability properties and are thermal welded with hot air. This welding method effectively fuses and bonds together the molecular chains: the welded MAPEPLAN T M membrane’s seams withstand the pressure of the water and are mechanically strong.
