Design, manufacture, supply and installation of systems for all types of green roofs and biodiverse roofs. Deckdrain is a subsurface drainage layer, predominantly used in intensive roof garden applications where the requirement is to move excess water to the outlets as quickly as possible. The Roofdrain reservoir board is used when there is a requirement to maximise water retention to support vegetation layers (as well as drainage), for example on extensive green or biodiverse roofs.

Toits verts extensifs
Extensive Green Roofs are the best known type of green roof and are relatively self-sufficient and low maintenance, often incorporating sedum or wildflower mats. Extensive Green Roofs contribute towards improving air quality, minimising / softening the visual impact of the roof and assist in controlling rain water run-off; as well as enhancing the acoustic and thermal properties of the roof. Extensive Green Roofs, often referred to as living roofs, sedum roofs or wildflower roofs, are the most common type and are relatively self-sufficient. They are not designed or constructed with the intention of being trafficked by pedestrians. Whilst not providing an amenity area, they do contribute to improving air quality and filtering pollutants, reducing the visual impact of the roof and assist in controlling rain water run-off / harvesting in addition to enhancing the acoustic and thermal properties of the roof.
Toits verts intensifs
Intensive Green Roofs, often referred to as roof gardens, may be landscaped to include trees, lawns, flower beds and paved areas. With an intensive roof the only real limit to its scope is the imagination of the architect and the structure necessary to support it. Many modern developments incorporate landscaped roofs at ground level, for example above basement areas and underground car parks. These are commonly referred to as podium decks. The decked areas themselves create additional amenity space on urban developments.
Toits Biodiversifiés
Biodiverse Roofs replace and often enhance the local habitat that would otherwise be lost to a new development. Biodiverse roofs are designed to create a natural habitat to support a variety of plants, birds, animals and invertebrates. Biodiverse roofs can contribute significantly towards achieving additional sustainability points, as well as improving air quality, assisting in controlling rain water run-off and contributing to enhancing the acoustic and thermal properties of the roof. The purpose of a biodiverse roof is to replace and often enhance the habitat that would otherwise be lost to the new development. Designed to be relatively self-sufficient; they are not designed or constructed with the intention of being trafficked by pedestrians, but instead to create a natural habitat to support a variety of plants, birds, animals and invertebrates.
Design, supply and installation of a wide range of green roofs and biodiverse roof systems. This typically includes everything above the waterproofing system; from attenuation systems, drainage & reservoir layers to insulation, paving, growing media and vegetation layers (such as sedum and wildflower).
Types de toit et avantages environnementaux
In the case of Green Roofs, virtually any type of roof structure can be adapted to accommodate the system components. These include domestic and commercial, both new-build and retro-fit, flat and pitched. The significant benefits of a Green Roof are wide ranging, such as helping to mitigate the effects of climate change, whole-life cost benefits and providing amenity areas.
L'urbanisation et le développement des terres créent des surfaces dures et imperméables qui n'absorbent que 5 % des précipitations, laissant le reste s'écouler dans les systèmes d'eau naturels et artificiels qui ont du mal à faire face aux volumes. Cela a été mis en évidence lors des récentes inondations survenues dans tout le pays.
Les toits verts peuvent jouer un rôle important dans l'atténuation de ces événements, avec jusqu'à 95 % des précipitations absorbées par la surface végétalisée, en particulier lorsqu'ils sont conçus comme élément intégral d'un système de drainage urbain durable, également connu sous le nom de SuDS. La conception du SuDS exige que l'eau tombant sur un site de développement ne soit pas simplement canalisée vers les égouts pluviaux et rejetée dans la rivière locale. Au lieu de cela, le drainage est conçu pour imiter celui que l'on trouve dans la nature, où l'eau est atténuée, traitée et infiltrée par des processus naturels.
Green roof systems have been used extensively across many leading sustainable developments across the UK. As with many sustainability aspects, the final type and design of the green roof system is dependent on the project specific requirements. Geosynthetics offer a complete green and blue roof service; including design installation and on-going maintenance contracts.
