What are the design considerations for roof gardens

The main thing is to pay attention to waterproofing and drainage, and then the choice of plants, do not choose the kind of plants with strong root punctures, otherwise it will damage the structural layer of the roof.

1. People-oriented: As an important place for public activities, the roof garden is designed with the principle of "people-oriented". In the design of the roof back to the garden space, people's multi-dimensional feelings are fully considered.

At the same time, the rest and public facilities in the garden, such as pavilions, benches, garbage cans and all kinds of floor lamps, are based on humanized design, taking into account both function and beauty, reflecting the modern requirements of green ecology.

2. Ecological principle: fully consider the climate characteristics of Liuzhou, and evaluate the environmental characteristics of the surrounding area, so as to realize the harmonious coexistence of man and nature, roof garden and regional environment.

Ask me.

In the implementation of roof garden construction, no matter what kind of facilities shall not open or destroy the waterproof layer or protective layer of the roof. In addition to overflow holes and gutters, water outlets, drainage pipes, etc. should also be set up, and regular cleaning and dredging should be done.

The whole roof is treated with leakage, and the waterproof layer treatment should adopt composite waterproof facilities, that is, two lines of defense are set up with a coated waterproof layer and a reinforced fine stone concrete rigid waterproof layer. The coating film waterproof layer should be made of non-woven fabric for one cloth and two coatings or two cloth for six coatings, and on this basis, the rigid waterproof layer and the roof flooding must be made at one time to ensure its waterproof quality. After the construction of the waterproof layer of the coating film is completed, a waterproof test should also be carried out.

When I bought a new house, especially those who like to grow flowers and vegetables and dream of living an idyllic life, I bought one with a roof and a terrace. The construction of the roof garden needs to pay attention to waterproofing, I think waterproofing is very important, if it is all flower pots and flowers, it doesn't matter, but if it is a flower pond, fish pond, rockery and the like, you need to do a good job of waterproofing, waterproofing is done, and then paving soil and the like, what you want to plant, want to lay the lawn and lawn, there is no worries.

When the roof garden is designed and renovated, there is sufficient watering equipment, such as faucets, pipes, sinks, etc. It is convenient for watering flowers and plants. There is also to set up some solid flower shelves, shade the flowers and plants, for plants to climb, and can be raised like a pergola, very beautiful and comfortable.

There are two most important ones, one is the load-bearing problem of the building itself, and whether the load-bearing is feasible must be considered first when designing the roof garden. The other is the problem of waterproofing, once the roof greening is done, a considerable part of the entire roof area will be in a humid environment for a long time, at this time the requirements for roof waterproofing will be very high, and the waterproof should also be tested for four days and four nights to ensure that there must be no waterproof problem, and then one is the root puncture of the plant, now there are generally two kinds of physical root resistance and chemical root resistance.

Now our house is built on top of a small garden, speaking of precautions, the construction of the roof garden, concealed engineering to pay special attention, especially waterproof, to put the top priority to deal with, to ensure foolproof waterproof measures, but also to plan drainage, to ensure that the water can be drained away in time, as well as the bearing should also be paid attention to, the thickness of the covering soil and the point should be placed in the position of the structural column, the use of light soil, to understand the load distribution of the roof, to ensure safety.

It is a load-bearing problem, although there is no need to worry about the load-bearing aspect of the house now, but try not to use too large flower pots, or try to use some light soil, which is a metaphor for flower friends before laying soil to raise flowers and vegetables, laying a layer of leaves and hay under the soil, which is relatively light and fertile.

In order to reduce the load, pavilions, corridors, flower beds, pools, rockeries and other heavy scenic spots should be designed in the load-bearing structure or the position of the smaller span, and at the same time, light materials such as artificial soil, peat soil, and humus should be selected as much as possible.

In order to ensure that the plants on the planting roof can be cultivated and grown, it is necessary to waterproof and eliminate stagnant water, so as to achieve no seepage and no leakage, so as to meet the use function of housing construction. If leakage occurs, the entire roof must be redone, so the waterproofing problem is the most important problem after solving the load problem. The waterproofing of the roof garden is one level higher than that of the general residential waterproofing, that is, at least the second level of waterproofing and the second layer of flexible waterproofing.

Planting soil layer: Generally, the soil that can be cultivated in the field is used as the base soil, and then mixed with loose matter to form the planting soil. Filter layer:

The isolation layer can be made of non-woven fabric, glass wire cloth, or plastic cloth, which is not bonded for water permeability lap joint.

Second, there are two important things, one is the load-bearing problem of the building itself, and whether the load-bearing is feasible must be considered when doing the design of the roof garden. The other is the waterproof problem, once the roof greening is done, a considerable part of the entire roof area will be in a humid environment for a long time, at this time the requirements for roof waterproofing will be very high, and the waterproof should also be carried out for four days and four nights of closed water test to ensure that there must be no waterproof problem, please consult Henan Laike Garden for details.

There are many issues that need to be paid attention to when designing a garden on the roof, what are the precautions when designing a rooftop garden? Today, PCHOUSE will answer them for you one by one.

1. Waterproof drainage.

Waterproofing is one of the most important projects in roof garden design, and if waterproofing is not done well, it will be troublesome if it penetrates indoors. The same goes for drainage, the slope of the garden floor and the drainage openings must be properly planned.

Second, the roof load-bearing.

The building can safely bear the load of the roof garden plant soil and other facilities, while keeping the roof garden design beautiful and beautiful, but also be careful not to exceed the load-bearing limit of the house, so as to be both beautiful and safe! In addition, the construction of a garden on the roof must be firmly protected to prevent people from falling.

Third, the selection of materials. Waterproof materials should be selected that do not flow at high temperature, do not break at low temperature, are not suitable for aging, and have good waterproof effect.

Fourth, the choice of soil.

Because the weight bearing per square meter of the roof is limited, it should be taken into account when designing the garden or selecting materials, so the roof garden design should not be used just by finding some soil, but by screening and using lighter soil.

Fifth, the choice of plants.

The plants in the roof garden design can be used in soilless lawns, with aromatic and colorful plant applications so that we don't need to go out and smell the flowers.

For villa houses or those who live on the top floor, they will want to have an independent garden, and this idea is actually very good, but what should you pay attention to when designing a roof garden, how to design a roof garden to look good? Today, I will take you to a detailed understanding of what to pay attention to in the design of the roof garden, and if you want to design the roof as a garden at home, you should hurry up and learn.

1. Load-bearing. For safety, what needs to be considered is the load-bearing capacity, if the load-bearing capacity of the roof is small, you can plant low shrubs or creeping plants, such as creepers, wisteria, etc. If it is a house with good load-bearing capacity, you can carefully create the desired garden, you can create an open garden according to the layout of the garden, but in order to ensure safety, you should follow the purpose of building facilities such as fewer or no pavilions.

2. Protection. For families with better load-bearing capacity and arbors planted on the roof, the center of gravity of the arbor is relatively high, and its stability will become worse after planting on the roof, so if the arbor is planted, it must be protected to protect the arbor from remaining stable in the wind and rain. At the same time, it is also important to pay attention to the safety problems caused by falling objects, so it is important to strengthen the protection.

3. Plants. It is also necessary to pay attention to the choice of plants planted, to plant plants that are more adaptable to the climate, not to plant shade-loving plants, after all, the light on the roof is relatively sufficient, and the temperature difference is. If you are planting flowers on the roof and build a flower shed, the flower trellis can keep the flowers from the sun and rain under the condition of sufficient light, and the material of the flower trellis should be lightweight.

Flowers are chosen to be cold and heat resistant, such as chrysanthemums.

Fourth, furniture. The roof garden is open and can be used as a relaxing place, and there are tables and chairs on the roof for people to rest. The selection of tables and chairs should take into account the problem of deformation and cracking of tables and chairs due to moisture or too much sunlight, so do not place solid wood tables and chairs.

It is also possible to install a large parasol on the roof so that you can rest on the roof even when there is sunlight.

Compared with the ground garden, building a roof garden is not only costly, but also more technically difficult, and there are many restrictions on the landscape elements that can be created, so there are many principles to follow

Can a roof create a landscape?

The roof garden can create a landscape landscape, but try not to create a large landscape landscape, because the weight of the large landscape landscape is likely to exceed the load capacity of the roof, and the construction difficulty is also relatively large, the building structure of the house is aging over time, and the damage to the roof is also relatively large, so if you like it, you can create a small landscape landscape, which has charm and will not cause damage to the roof!

What plants can be grown in a roof garden?

There are two types of plants planted in the roof garden, one is the root system penetration ability is particularly strong, because this kind of plant may penetrate the building structure, damage the waterproof layer of the roof, insulation layer, etc., the other is a precious and delicate plant, because the environment of the roof is still relatively bad, the survival rate of planting this type of plant is very low, even if the garden owner invests a lot of time and energy, it may not be spared! Therefore, the roof should be planted with strong performance, such as waterlogging, cold resistance and other plants!

Do you need to raise the roof railings?

On the one hand, many communities now have several buildings, and there are roofs, and the view of the roof is much wider than others, and it can be said that it is unobstructed, and for some garden owners, they will pay great attention to personal privacy, so that the railing should be heightened and opaque, so that the space will be private enough. Another benefit of raising the railing is that it can stop naughty children from climbing and causing irreparable accidents!

The roof garden is the same as the general garden, and the main elements are natural landscapes, various buildings and plants, and a beautiful landscape is composed according to the basic laws of garden beauty. However, because the gardening in the limited area of the roof is subject to special conditions, it is not completely equivalent to the garden on the ground, so it has its particularity. The roof creates a garden, and all garden elements are limited by the load on the top floor of the building.

Therefore, it is not possible to install large-scale natural landscapes and stones in the roof garden. When setting up small rocks, it is necessary to consider the load-bearing range of the building roof. In terms of terrain treatment, flat land treatment is the main one.

Pools are generally shallow pools, and fountains can be used to enrich the water features.

Its design principles can be summarized as follows:

1) Adhere to the design principles of applicability, exquisiteness, safety innovation, and economy.

2) Through scientific and artistic techniques, reasonable layout and design of flowers, trees and sketches.

3) Rational construction of pools and installation of drainage systems.

4) Choose a fertile, light soil as the substrate for plant planting.

5) Plant species should be beautiful, dwarf, shallow-rooted, wind-resistant flowering shrubs, small trees, bulbous flowers and perennial flowers.
