How to make vegetables on the roof waterproof?
1. Waterproof treatment: According to the current design and construction specifications, if vegetables are planted on the roof, there should be two waterproof layers, one flexible and the other rigid. SBS can be used for flexible pipes, and impervious concrete can be used for rigid pipes. But first we must check whether the increased load is enough.
2. Load: In order to ensure that the vegetable garden on the roof can be within a safe load range, the soil should not be piled too high, and a brick wall should be built next to it to fix the shape of the vegetable garden to prevent the soil from being washed away by rain. The water used for watering vegetables is directly connected to the roof from the water pipe at home. Water holes should be set up, and fine iron nets should be installed at the drain to filter the dirt, so that even if it rains heavily, the water can be discharged in time and will not be deposited on the roof of the house.
What material is good for roof waterproofing?
First, the open-air rooftop must first determine where you want to be waterproof. Some open-air parts or large-area tooling roofs are very suitable for using waterproof coiled materials.
Second, if the balcony and roof need to be constructed by combining rigid waterproofing with flexible waterproofing, the K 1 1 waterproof slurry should be applied first, and then the protective layer of mortar waterproof agent should be made, so as to fully meet the waterproof requirements. Waterproof coating must be done well. Not only should we choose a good waterproof coating, but also the details we should pay attention to during construction. For example, you need to brush more times and know how to brush.
Third, the combination of rigid and flexible, that is, flexible waterproof materials (coiled materials, coatings, etc.). ) plus rigid waterproof material (mortar waterproof agent) has a good effect. Flexible materials are mainly coiled materials and linoleum. At present, the better choice is polymer waterproofing membrane, which has convenient construction and good waterproof effect, followed by modified asphalt linoleum, while paper tire linoleum has been gradually eliminated and should not be used again. During construction, the coiled materials will be laid on the waterproof cement mortar floor in turn, and the lap joint will be melted and bonded firmly with a blowtorch, so that the waterproof layer will be fine.
4. Rigid waterproof materials are divided into waterproof concrete and waterproof mortar. This waterproof method is simple in process and convenient in construction, and ordinary masons can achieve good quality requirements by using ordinary plastering methods. Moreover, the cost is low. On the premise of the same waterproof grade, the comprehensive cost is much lower than that of flexible waterproof materials, which is 1/2- 1/3 of other waterproof materials. What is important is safety, non-toxic and environmental protection.
Waterproof paint actually plays a very important role, that is, when you brush, sometimes you must know where to brush. These must be known, so as to play a better waterproof role. In fact, waterproof coating is a kind of film, which is formed by chemical reaction after being coated on buildings. Through this film, the building surface is isolated from water, thus playing a waterproof role. At present, there are generally two kinds of waterproof coatings on the market, one is polyurethane waterproof coating and the other is polymer cement-based waterproof coating.
Six, waterproof coating is characterized by good waterproof performance. Waterproof material can resist high temperature and low temperature, the high temperature can reach 170 degrees Celsius, and the low temperature can reach -20 degrees Celsius without breaking. This coating has strong adhesion and can be well attached to glass, ceramics, plastics and other materials.
Seven, under the action of external force, it will not delaminate, with strong adhesion and can form an integral waterproof system. In addition, waterproof coating is also an environmentally friendly coating, which is non-toxic and tasteless. It will not have a bad influence on people's health.
What waterproof material is used for the roof? In fact, there are many waterproof materials on the market now. No matter what kind of waterproof material you choose, you should consider environmental protection, and materials that will not harm the human body can make us safer to use. In addition, the problem of how to waterproof roof vegetables is very important. Only by knowing the waterproof methods can we ensure the waterproof quality in actual operation and avoid water leakage in future houses.
