For today's food, the quality of many things has become worrying. Of course, vegetables are the same. Nowadays, many people choose to grow their own vegetables, but there is no free space in the yard, so they choose to grow vegetables on the roof, which must be waterproof to avoid water seepage. Next, Bian Xiao will introduce how to make vegetables on the roof waterproof.

How to make vegetables on the roof waterproof

According to the current design and construction code, if vegetables are planted on the roof, the waterproof layer should have two layers, one is flexible, the other is rigid, SBS can be used for flexibility, and impervious concrete can be used for rigidity. In order to ensure that the vegetable garden on the roof can be within the safe load range and the soil can not be piled too high, water holes should be set to drain the water in time and not to deposit on the roof.

What should I pay attention to when growing vegetables on the roof?

1, can't destroy the original structure of the house. Before planting a vegetable garden, we should first understand the load-bearing capacity of the roof and not blindly plant it. Generally speaking, the load of reinforced concrete roof is 150kg/m2, and the weight of loose soil per cubic meter is about 1t- 1t half. That is to say, the roof load is reached when the thickness of soil layer reaches about 15cm. Soil that absorbs a lot of water will increase the bearing capacity of the roof and affect the structure.

2. Newly-built residential areas generally adopt new materials for waterproofing, but a layer of polymer building materials should be added for double protection. Try to use plastic planting pots, ceramic planting pots or other containers instead of foam boxes. Because watering vegetable fields will inject a lot of water, it is necessary to make a good drainage system in advance to prevent water from seeping into the roof. Almost any type of container can be used to grow vegetables, as long as it is strong enough to provide enough space and drainage channels.
