When it comes to protect from excessive moisture foundation structures, first of all talk about waterproofing.What is needed in this case the drainage?In fact, the purpose of waterproofing to prevent the destruction of the foundation of water and drainage task - to withdraw from the construction of the water.Events for the Development of drainage and waterproofing performed "hand in hand", but to talk about their interchangeability is not necessary.
modern drainage of foundation engineering is a system that takes away from the foundation and walls of the melt, groundwater, rainwater.At a high level of ground water or finding land in the valley definitely need to do something to keep the water in contact with the base, and even better to remove it completely from the site.These measures will not be perched, and rates of seasonal rise of the water level will be significantly reduced.
drainage system represented by products of metal, which are placed around the perimeter of buildings in a prepared trench.Modern building market offers pipes which are wrapped in a special material - geotextiles.Thanks to him, the drainage lasts longer.It is not only important components of the drainage system, but the way its organization.Provide the effect of a well-prepared and carried out the work.
foundation to be protected from water, there are two types of drainage: and trim ring.If this is the first, here as one of the walls of the trench appears foundation.The second option - to dig a trench, stepping 1.5-3 m. Trim variant is used in the presence of ground or basement floor, and in their absence cost the annular drainage.Different ring from the wall, and even rounded, soft turn of a pipe.There is no question about the exposure of some precise distance, most importantly, a maximum of 3 m. However, the main principle must remain inviolable: pipe lay lower than the sole foundation.
Any drainage around the house consists of several stages, which will take about a couple of weeks.First, dig a trench fortified, and then, if it is provided drainage trim, clean the foundation of the old waterproofing and any contamination.It was dried, and then put a new waterproofing.The next stage - laying of geotextile, filling gravel underlay.Then comes directly laying drainage pipes, and after the installation, if necessary, storm sewer.After that, the tube is filled 50-70 cm gravel, but you can take and sand, especially if it is an annular drainage.
