• Creating a drainage system. In order for your site to have any swamping, it should be installed on it a special drainage system. This will allow rain and groundwater not to accumulate on your site, but to immediately go to the drainage system and at the same time do not undergo construction. The simplest and most inexpensive construction of the drainage system is open drainage. To do this, you need to dig the grooves of a small depth, which will be located around the entire perimeter of your site. Closed drainage can also be used, but it is more complex and expensive, but at the same time much more reliable and practical.
