Protection layer – Rubber carpet

It is a carpet made of polyurethane & rubber and it protects the waterproofing and the insulation of the green roof. In order to evaluate the compatibility of this layer, the followings must be checked: the quality of the material, its thickness, weight and tensile strength. Mechanical protection is necessary while building green roofs.

Protective layer – Geotextile

This geotextile is made of polyester fibres, a mixture of mechanically reinforced fibres and regenerated polyester and polypropylene. It protects the waterproofing and the insulation of the green roof. It is able to absorb 3-6 l/m² moisture, depending on the product. The geotextile mechanically protects lower layers against drainage elements and also helps the uniform distribution of storm water, which was not taken over by the drainage layer.

Protective layer – Protective veil

It is made of recycled polyester fibres and protects the waterproofing and the insulation of the green roof. It can absorb between 2-3, 5 l/m², depending on the product. This cover mechanically protects lower layers against drainage elements and also helps the uniform distribution of storm water, which was not taken over by the drainage layer.

Even in the early design stage of a rooftop or terrace ecological construction, we can advise you in order to choose adequate elements for your investment.

Protection layers of green roof’s waterproofing and insulation have to mechanically protect lower layers against drainage elements.

Manufacturers whose materials we use for landscape works are well known all over the world. We already had some common projects, and results were reliable and spectacular. If you choose us, the quality of building elements is doubled by the qualified human professionalism. Our team is well experienced in the use and maintenance of all building elements of a green roof. We can build extensive vegetation on industrial halls, intensive green terraces on office buildings, we can also create recreation and relaxing areas, intensive green roofs for high pedestrian traffic on the top of shopping malls, and many other ecological solutions. Thanks to the competence and professionalisms of our team, all materials used are compatible. Protection and filtering layers, drainage of the green roof, together with control boxes, delimitation elements, evacuation gutters are key components of a green roof system.
