Mr MA Xiu Road West 53rd residents, like the rooftops kinds of fruit, potted or abandoned freezer used to grow vegetables. Mr MA on drainage problems very seriously, his Cabinet and basin floor mats at the end of a small tile, water space, the extra flow of water through the soil from the bottom up. Meanwhile, the gaps between insulation layer of cement sheets are drainage, row to the row of sinks, roof over the years no leakage problems.
, Nanning city, this is a number of "sky garden". Reporters visited more than one community discovered that fewer new communities green roof, old community food shed many people to take the initiative to build the roof of the building, and so on. The roof is divided into several large pieces of vegetables, vegetable garden enclosed in red brick, planted with sweet potatoes, scallions, leeks, etc. In this regard, the "Garden" considers itself the garden belongs to a kind of green roof can help beautify homes and green city.
Opponents have reason to grow vegetables mainly roof mosquito and Ant, fertilizer smells, impact air your quilt and so on. Otherwise, many people say, himself as well as on the roof is a small vegetable garden, but the late start, only subsequently watched his neighbors garden, "they got me a vegetable garden, in fact, is the monopoly of public resources".
"The Department answers" Department of housing said that roof belongs to all owners of the building, property for farming in the roof could certainly tubes. Therefore, roof gardens residents built the air, you first need to coordinate with the other owners of the property, relationship, with clearly defined responsibilities and avoid later maintenance caused unnecessary trouble. 2 roof is leaking do.
"Some people grow vegetables not professional at all, could easily lead to insulation damage, pose a security risk. The "Hengyang road, Nanning city, a community of top floor residents told reporters that the silt being washed from their rooftop vegetable garden so badly that led to jams of drainage pipe, walls and ceiling and water seepage. In this regard, the "garden," said Garden only a corner of the roof, water leakage not caused by growing vegetables. "Leaking more mainly because of the ageing of housing, because vegetables have done waterproofing measures before. ” Reporter learned that, although there are a lot of people on the roof greening, but do not much better, and even received a lot of "Garden" and other contradictions and disputes between tenants. The bearing from green roofs, leaks, follow-up and maintenance problems as key issues of public concern.
"The Department answers" "Greening the roof, was not simply a pile of dirt on the roof, then planted flowers and vegetables. "The housing sector experts, vegetables have some relation with leaking roofs. Because vegetables people don't pay attention, water deposits, mud weight will give housing forming pressure, causing the housing gap. To this end, I introduced standard requirements, building solid greening engineering design and construction, the engineer shall have the appropriate qualification level. After completion, subject to acceptance. How to address people's worries? "Rooftop farms try not to plant small trees and roof garden soil requirements are very high, the lighter the better. "Office of State housing official said, green roof design, construction, architectural and structural design, increased gross weight of roof greening system must be counted. If the original design did not take into account green loads should not be green, otherwise it will cause safety problems. Waterproof penetration measures also need to be carefully designed, because plant roots have a strong ability to puncture, and secrete a corrosive force SAP, many waterproofing materials withstand punctures. The official said green roof forms. Modular and should choose paving leaves small, styling easier plants climbing and hanging-type should be planting climbing or hanging plants; bag or bag and Board slot for shielding plate channel, you can select leaf shape larger plants; ducts-dimensional green to grow Edible vegetables. In what manner, what kinds of plants, the public can choose. Of course, in a community, based on the whole body to consider the entire community of green effect, you can do the overall planning and design of green to avoid clutter.

A, on the roof garden should know before the bearing load, not blindly plant. Generally people of reinforced concrete roof, weight-bearing load of 150 kg/sq m, planting soil loose weight is 1 ton per cubic metre to around 1 and a half tons. That is, the layer thickness of 15 centimeters, on reaching the roof load limit.
After b, rooftop Vegetables, water is a problem not to be ignored. If you grow vegetables on the roof and need to be waterproof. Waterproof layer asphalt paving of the old community in General, can be aged for more than 10 years, if you want to grow vegetables, you must add new waterproofing material waterproof layer. New community also needs to add a layer of polymer materials, double protection. C, as far as possible with plastic plant pots, ceramic planting pots or other containers, instead of the foam boxes. D, due to water the vegetable garden would have a lot of water, so to advance the drainage system to prevent ground water seepage caused the roof.
E, the family grows vegetables commonly used soil cultivation. The training ground in the agriculture market, you can buy, according to vegetable species a dedicated training ground.
Press review: Guide to building solid greening technique introduced in Guangxi, and roof gardening vegetables Author: Nan Guo morning post journalist Mr Tsui Roof gardening, growing vegetables, mess would cause leakage. How to solve this problem? On November 16, the reporter was informed from the State Office of housing and urban-rural development, recently issued the Guide to building solid greening technique of Guangxi (hereinafter referred to as the Guide), for vertical planting provides operational specifications. However, in roof and wall surface greening, grow vegetables, and so on, should fully consider the roof load and use requirements. The Guide came into effect on January 1 next year 1: walls roof and balcony can be "dressed in green clothing.
Autonomous regions live built Office about head said, so-called building stereo green, refers to of is full using building space (wall surface, and column, and flat or slope roofing, and window, and balcony, and corridor, parts), select climbing plant and the other plant planting, and attached or Pu posted Yu various structures and the other spatial structure Shang of green way, main including vertical green wall, and balcony window corridor green and roof green three species common mode. The Guide applies to the whole area of new construction, renovation and expansion of civil and industrial buildings walls, roofs, balconies, pools and other parts of the vertical greening of planting. "Vertical planting is the direction of future urban greening can not only beautify the urban environment, but also improves their microclimate. "The official said, using plant transpiration, evapotranspiration, reducing building heat absorption of solar radiation, changing the balance of the heat and humidity of the environment, reduce air conditioning loads, building energy-saving and eco-friendly. 2 questions about farming in the roof is solid green?
Guangxi construction recommended by solid greening technique commonly used modes, "rooftop farm" mode of many citizens. "The use of vertical greening the roof farm, meaning that you can grow vegetables in the roof, which is a form of roof greening. Grow vegetables in the roof must be in accordance with the specifications, no pretext of green building on the one hand, on the other hand not overly green the damages of houses in safety. "Insiders said, the roof garden must have waterproof, waterproof material must be strong resistance to penetration. In roof greening, the many old buildings without fortification or water resistance, resulting in attic leaking since Ivy can root into the roof. State officials said the Office of housing, vertical planting using native plants, selected plants should have strong anti-pollution capacity, adaptability, poor resistance, drought tolerance, bearing in mind the color, height, and seasonal variations. Specific,, vertical green wall can with climbing class plant support system, and module type planting box, and planting bag, and fixed planting tube slot, way; balcony green to select drought sex, and management extensive, and root developed of plant, and some small and medium herb or Woody climbing plant, also can for container planting; ornamental type roof green can according to roof load contains and using needs, appropriate set Pavilion, and Gallery, and flower, and large collection of, and waterscape, Garden sketch, but scale to suitable, and has reliable of security fixed measures.
"Rooftop farms try not to plant small trees and roof garden soil requirements are very high, the lighter the better. "Office of State housing official said, need to be aware of is that green roof design, construction, architectural and structural design, increased gross weight of roof greening system must be counted. If the original design did not take into account green loads should not be green, otherwise it will cause safety problems. Waterproof penetration measures also need to be carefully designed, because plant roots have a strong ability to puncture, and secrete a corrosive force SAP, unable to withstand the many waterproof material.
"Rooftop greening is not simply a pile of dirt to get to the top, and then planted flowers and vegetables. "Office of State housing official said, calls for the Guide, building solid greening engineering design and construction, the engineer shall have the appropriate qualification level. After project completion, and acceptance.
I had heard on the roof garden, many people are looking forward to. In their view, people on the roof and a garden, to allow yourself to eat "rest assured". However, the public is more concerned about, according to garden, price will not be very high?
The Guide clearly now solid green insulation technology of high construction and maintenance costs. According to relevant statistics, including waterproof, transportation, labor, building vertical planting costs about 1000 Yuan/square meter; on the roof garden, the cost should be less. It is recommended that members of the public, and take appropriate measures to reasonably reduce vertical greening of the construction and maintenance costs.
People want a roof garden or vegetable garden, at the time of planning and design, to consult the local housing or housing sectors, and by looking at the design of the building, verify the confirm that the original design of the building can withstand the Green load weight to be built.
