Roof Garden Explanation?
Display your colors on the balcony or on Roof and in your yard Even without a garden, you can have your hand green (Green Roof)! Alone or in association with your co-residents, on your balcony (you have not spaced so without a garden), in the courtyard of the building or on the roof, do not hesitate to express yourself in order to embellish your frame of life and enrich the biodiversity of the neighborhood.
Protect your home with plants.
Like the garden and its fence, the balcony and the railing talk about you and contribute to the quality of spaces public. For your balconies, or classes small sizes, prefer plants that do not take up too much space and that can be grown in pots. Think about them monitor regularly, to water them with recovered rainwater and to vary the types: beautiful flowering, foliage interesting, aromatic plants, fruit, vegetable, perennial… Think also to the hanging plants that adorn without taking up too much space. The bushes red fruit producers such as raspberry, blackcurrant, gooseberry, blueberry, mulberry, strawberry will also find a square. They can be planted in vats or planter and join the useful to the pleasant.
If your space is really small, opt for pergolas or trellises who will decorate your outside and will be relevant media for your plants. Choose wood species local (chestnut, acacia, oak) or wood labeled F.S.C. Dress up your facades Contrary to the common idea, climbing plants do not degrade the facades, but they protect them rather excessive temperature variations or moisture. By creating a microclimate intermediate between the plant layer and the wall, they act as an additional insulating layer.
Alone ivy affixed to fragile walls risk of damaging them because of his strong crampons. By opting for climbers, you will benefit from protection against ultraviolet rays that will not degrade your walls and against heavy rain or hail which will be amortized by this facade natural. It is wise to shift a little the foot of the wall planting for allow him to aerate and receive the precipitations. Some climbers will require trellises while the others will climb on their own.
local climbing plants Honeysuckle (Lonicera periclymenum), European clematis (Clematis vitalba), Eglantier (Rosa canina), Raspberry (Rudus ideaus), Hops (Humulus lupulus), Ivy (Hedera helix), in nature, these species cling to trees, at home, they can decorate your walls.
A garden on the roof?
Green roofs are in full expansion in cities. They have three advantages: ornamental, environmental and economic. Better insertion of buildings in the landscape is possible. We can, in addition, install them on any infrastructure: building, industry, pavilion, shed …This islet of greenery will attract very quickly a varied fauna that will appreciate resting, a little away from the stress townsman. The vegetation layer stores temporarily rainwater before let it escape to the water network rain, slowing the flow.
It avoids overloading the network, which decreases the risk of flooding. The plants used can play a role of atmosphere remover by absorbing for their metabolism of elements toxic to humans. The expensive initial expense is depreciated by extending the life of the protected roof. The insulating capacity of the roof is higher, thereby reducing the energy expenditure. After having verified that the planning document of your commune allows it, change roof!
Protection of the Roof and Structure
The single most important element in rooftop garden construction is protecting the integrity of the roof and the structural components under the garden. For this reason, there must be waterproofing of exceptional longevity to prevent damage and to reduce the possibility of long-term expensive reconstruction. For this reason, it is recommended a completely new waterproofing layer be added to the existing structure to ensure the longevity and integrity of the waterproofing system. Load Bearing Capacity
The structural engineer should verify the maximum load-bearing capacity of the existing structure. These figures should be available from the records of the previous construction of the helipad. Typically, a minimum additional dead load limit of 150 psf between columns is needed to accommodate the construction of a roof garden. Loads above columns and at the roof’s edge can be considerably higher, however, a structural engineer should be consulted to establish the load-bearing capacity of those areas. These higher load bearing areas should be used to accommodate larger specimen plantings and trees.
As mention before, a completely new waterproofing system should be installed to protect the building’s structure. There are several types of waterproofing available, however, elastomeric materials offer the greatest protection. Bituminous waterproofing should be avoided. Over time the organic components in bituminous waterproofing interact with the soils and the plant materials and therefore increase the likelihood of system failure.
A properly installed waterproofing system can last the lifetime of the building, however, a single small leak may require the removal of the entire garden to find and repair the damage. Therefore, in order to ensure the integrity of the waterproofing, it is recommended a protective topping coat of concrete be applied, as soon as possible, following the installation of the new waterproofing.
Protection of the Structure The single most important consideration regarding roof and deck garden construction is protecting the roof and structure from damage due to excessive loading or leaks.
A structural engineer should always be consulted prior to roof garden landscape design and construction. Rooftop structures must typically be able to support a dead load of 150psf to accommodate the construction of a garden. The roof must be completely covered by an elastomeric material and protected by a concrete topping slab.
