Is it necessary to insulate the pavement and how to do it correctly

With warming comes not only gardening time, but also construction. Everyone who planned to build a new house, necessarily think about it. how to make a pavementWhat it should be and what to use for its arrangement. The question is not trivial, it must be approached with special care.



Editorial "Site" I tried to gather information about it. We managed to highlight several common points that are important to pay attention to. If all this does not suit you, then you should look for specialists with experience. But everything, as they say, in order. Keep your head down.



It is necessary to remember one thing: a pavement is not a panacea for possible problems. Its direct task is not to allow moisture to accumulate directly at the walls and foundations. If the soil is clay, thick, there is a lot of sand in it, the pavement should be paid the closest attention. If this is not done, the weakening of the foundation, drawdown, or even cracks in the walls is only a matter of time. Okay.

1. Width
   Obviously, the pavement is built around the perimeter of the building, but how wide is it to make it? During the rain, water in large quantities drains from the roof, drain pipes do not always cope, which means that it will drip from the roof. It's better if the bridge stops this water. Therefore, it should be done with a margin, wider than the roof rays. 20-30 centimeters will be enough.
   
   
   
   
2. Slant.
   Rainwater should not accumulate on the pavement, which means that you need to take care of the slope. Thus, all moisture will be removed from the perimeter. In standard building codes, the slope is recommended to do 10 degrees, this is quite enough. It is also worth taking care of drain boxes: these can be sawed along the pvc pipe on a solid base. The water can be taken outside the yard.
   
   
   
   
3. concrete
   There are two types of windows: hard and soft. To solid include concrete, tile, asphalt. In this paragraph we consider the concrete pavement. The main problem is that the correct technological process is not observed, after which the concrete cracks, crumbles, becomes unusable. Here is the proportion that will give the necessary strength. Calculation per 1 m cubic concrete M250 for low-rise construction:
   
   concrete mixture
   • 330 kg cement M 400
   • 1 ton of small rubble
   • 700 kg of sand
   • 200 liters of water
   
   
   
   
   
   
   
4. Insulation
   In some cases, the pavement is insulated, even if a hard-type bridge is assumed. Insulation is a controversial issue, not everyone agrees with it. It is believed that it is designed to reduce the negative impact of low temperatures on the foundation, reduce soil freezing, and sometimes reduce heating costs. This point is important to consider on complex soils prone to swelling. Styrofoam plates are used, which in addition isolate the foundation from water.
   
   
   
   
5. Soft pavement
   These include options from gravel, light tiles, lawn. But that’s not all, because you only see the top of the complex structure. So that a soft pavement does not pass water, you need a powerful waterproofing base. In its role, a profiled membrane can act, the edges of which are closed on the wall. The membrane is two-layer: from the bottom a dense spine-shaped polyethylene that forms drainage, from the top - a special textile that prevents clogging of this drainage. A scaffold is placed on top of it.
