How to do Foundation drainage right?

If we are talking about how to protect from excess moisture Foundation structures, first of all talk about waterproofing. In this case, the necessary drainage? In fact, the purpose of waterproofing is to prevent the destruction of the Foundation water, and drainage task – to withdraw from construction of this water. Measures for improvement of the drainage and waterproofing are “hand in hand”, but to talk about their interchangeability is not necessary.

Modern Drain Foundation is an engineering system, which takes away from the Foundation and the walls melt, groundwater, rainwater. At high groundwater levels or the location of the land in the valley definitely need to do something to keep the water in contact with the Foundation, and even better is to remove it from the site. These measures will not be perched, and indicators of seasonal rise of water level will be significantly reduced.

Drainage system is represented by products of metal, which is placed around the perimeter of the structure into a prepared trench. Modern construction market offers tubes that are wrapped in a special material - geotextile. Thanks to him, the drainage lasts longer. Are important not only components of the drainage system, but also a way of its organization. Ensure only properly trained and the work carried out.

To the Foundation are protected from water, there are two types of drainage boundary and the ring. If we are talking about the first here as one of the trench walls is the Foundation. The second option – trench digging, departing 1,5-3 m. the wall version can be used in the presence of a ground or basement floor, and in their absence manage the annular drainage. The ring wall is different from another, and rounded, soft corners pipes. We're not talking here about the exposure of some accurate distance, most importantly, a maximum of 3 m. However, the main principle must remain inviolable: the pipe is placed lower than bottom of Foundation.

Drainage around the house consists of several stages, which will take about a few weeks. First dig a fortified trench, and then, if you provide wall drainage, clean the Foundation of the old waterproofing and any dirt. Dried it out then put the new waterproofing. The next stage-the laying of geotextile, backfill gravel underlayment. Then go directly to laying drainage pipes, and after installing the necessary storm sewer. After that, tubes covered 50-70 cm of gravel, but it is possible to use sand, especially if it is the circular drainage.
