Perimeter drainage - protect the foundation from moisture disastrous

What is and what is used trim drainage?

trim foundation drainage - a circular system of perforated pipes, which are mounted so that lie beneath the slope and take a position below the level of the deepest foundation of the foundation group.Angles systems have auditing manhole through which you can brush creates blockages.

Drainage pipes laid in the rubble, accumulate in itself water, and then sent to a holding pit.From there it is given in different ways for the border area.

Prifundamentny drainage performs another function - removes mechanical and hydrostatic pressure of the ground water in the basement.It should be noted that the installation of drainage pipes does not solve the problem of wetting the walls of basements and cellars completely.To fully exclude moisture from entering the structures that are below ground level, it is necessary to make a good waterproofing, to avoid any contact.

Site preparation for near-wall drainage device

At sites located on flat terrain, it is better to use open drainage system.Water accumulating in trenches, drains into the drip pan or evaporates.But such systems can be used in areas with slope.Then dig out two trenches, one above the other in parallel just below, so that it can intercept the drained water.

They should connect the pipe or dig another ditch for drainage.The system will work as follows: - water enters the ditch bottom, and from it to drain a pond or a well.Before you make the drainage around the foundation, it is necessary to prepare the ground for him.With the help of lasers need to fathom all the elevation changes and make a mark.Followed by making a bias in the marked locations by podsypaniya sand.

To avoid fraying the wall to do a 20-degree slope, but it should be much less than for clay soil because it is fairly stable and does not crumble.In order not to interfere with water flow, ditches should be periodically cleaned of debris.

main stage

laying drainage Now, to finish the device of wall drainage, it is necessary to lay pipes and cover them with gravel. At the bottom of the ditch is necessary to lay a geotextile which prevents silting of the drainage. On top of him is poured gravel with the same slope and attain to the level.Then made a groove in which is located the pipe in the gravel.Thereafter, it can be stowed.

Now you can connect the pipe, but you must make sure that they are connected by a slope of 1 cm to 1 meter of pipe length.Check this using tensioned cord, the same method can be used to check the evenness of the slope.Further, the pipe tightly wrapped geotextile that it did not get the ground.

then it should fix the rot-string.Then all is well fastened with gravel, and the top is filled with soil and sown grass.Thus, water is absorbed well drains by gravity and is sent from the slope in the reset position.Most often it is in a central sewage or drainage wells.

to a drain can be washed, it is necessary to build a vertical pipe on the corners with a lid that closes.A top of the pipe should be removed to a height equal to the height of the blind area.Now ready to drain.By the way, this type of foundation is considered the most effective method of protection.
