Types of houses landscaping

Extensive . Planter thickness of the soil often does not exceed 15 cm, it is often the low grass and evergreens. The roof seems to be a continuous green carpet, and can be planted « Gardens » on different types of roofs. In 1 square meter have to load no more than 20-30 kg, so there is no need to further strengthen the roof. Often used in container gardening, created lawns, small seating areas.

Intensive . In this case, the rooftop recreation area full equip:   with pergolas, paths and ponds, even! It should immediately be noted that the design of the roof should be reliable, since the load is impressive. With intensive form of gardening soil layer thickness may exceed the meter. Often these gardens break on roofs and high-rise office buildings. It is advisable to turn to the experts who will be given a document certifying that the load-bearing walls can withstand such weight. On 1 sq.m. accounting for up to 700 kg weight.

Indoor greenhouse . It stands out the so-called winter gardens, which create a special frame-type greenhouses. This building engineering, so all you need to plan carefully. Often, aluminum or steel frame, at least – wood. Light-transmissive materials – This double-glazed windows, float glass, stained glass, polycarbonate, well-established energy-saving glass. Under the glazing is given 80% of the total area of ​​the garden.

Party Light

Before proceeding to the breakdown of the garden, is to decide where it will be located. We have in mind is not just an abstract space on your roof and side light. Worst case – north plants gets a minimum of solar energy, and thus have to create additional thermal insulation and the heating system. South side – a huge amount of solar energy, and as a result, overheating of plants. In the south, it is best to create a covered conservatory with an additional dimming.

Garden in the West will maintain the accumulated heat, but if the sun is too hot, you need to think about shade. In the east, the likelihood that the plant will overheat, reduced to zero. Before lunch, the air is warm, and in the evening to give coolness.

Basis for planting

  • If the garden is planted on a cement-sand screed, should take care of the slope toward the drain (up to 5 degrees), then the flat roof will last longer. Ties are treated with primer, then the vapor barrier film placed carefully zaparivaya joints.
  • After that, a layer of insulating material needed – polyurethane foam, cork boards or polystyrene fits perfectly. If the layer is turned tough enough, on top of it impose another layer of screed.
  • For the separation of the layers need geotextiles – material of polypropylene or PVC fibers.
  • Then put a layer of waterproofing – it is necessary to protect the building from excessive moisture, often used reinforced membrane.
  • Required kornezaschitny layer that will prevent the germination of plants in hydro and thermal insulation layers and deeper.

Laying the other layers depends on what type of gardening you prefer. If this container gardening – enough to put concrete slabs or gravel. If it will soil the plants, it is necessary to carry out drainage system, lay a drainage layer – concrete block, stab pumice, gravel, drainage pipes lead. He lay on top of a layer of geotextile, and then later compactor substrate. Taken from the garden or the forest land can not be used!

If you decide to plant trees and shrubs pitched roof, the angle of inclination should not exceed 30 degrees, it is best just to plant a lawn of hardy grasses. About drainage can not worry – with a sloping roof drain excess moisture is excellent. Along the edges of the roof to install bumpers, or set the grid for supporting slopes.

Massive interior and trees are better placed in locations where the bearing beams or walls. Make extra protection from the wind, in-out on the roof, too, should not require effort (hardly anyone would want to 5 times a day to climb the ladder unstable), a pair of lamps solved the problem with lighting.


Often chosen for landscaping pochvennopokrovnye, dwarf plants with small root system. On the roofs of plants begin to bloom earlier than on the earth below. It is recommended to give preference to plants of local nurseries (trees brought from tropical countries can not settle down), undemanding plants. It can be physocarpus, turf, spirea, varieties of moss, juniper, parthenocissus. Softwood worth noting arborvitae, spruce cushion, mountain pine.

If you do not want to mess with the arrangement of the garden, you can buy ready-made system with all layers (also called « cakes »), such greening systems are ready for planting plants in this area specialize German companies ZinCo and FlorDepot.
