The water exerts pressure on the sides of the tank in which they are located, and therefore appropriate drainage systems must be installed.
In any case, it is important to consult with the engineer in charge of the project which means are most recommended.
Among the variety of solutions for dealing with hydrostatic pressure:
One of the ways to deal with hydrostatic pressure is by using materials designed for underground sealing and adapted to the pressure in question.
Most often, the pressure loads on these sealing layers and therefore they should be placed in several layers, depending on the local pressure.
Also, the deeper the bottom of the building is, the greater the number of sealing layers needed.
Sometimes also called a “perforation pit”.
These drainage pits are designed to deal with a wide range of problems including hydrostatic pressure.
The pit itself was drilled using a pile drill designed for this. After drilling, a sleeve is made of geotechnical fabric.
Coarse gravel is placed in the sleeve itself, and the fabric around it prevents and filters particles from the ground from penetrating the gravel layer.
The threaded pipe later carries water that accumulates in the soil or with the gravel and drains it to the bottom of the pit.
In close consultation with the engineer, a submersible pump can be added at the top for cases of failure or flooding.
At the top of the pit you can also add an iron mesh or a custom lid.
In underground buildings such drainage pits can also be installed in order to deal with the groundwater that is transported through the sleeve to the bottom of the drainage pit below the building.
The most important advantage of drainage pipes lies in the fact that they prevent the accumulation of groundwater.
A drain pipe is built in a perforated way so that water can always enter it from anywhere thanks to the small holes along its entire length. These holes allow free penetration of water that all drains into the designated place.
A special geotechnical fabric prevents blockages due to its virtue as a filter and thus allows the passage of water only.
It should be noted that the type of pipe itself varies according to the relevant ground route, but the most common of which is a perforated threaded drain pipe.
The main advantage of the above pipe is its flexibility and ease with which it can be installed in any condition.
The water is usually transferred from the pipe out of the compound we want to keep or to dedicated drainage pits.
How are drainage pipes buried?
The depth of the excavation varies depending on the route of the area.
For example: while in hard clay soils we dig less than a meter, in softer surfaces where infiltration usually occurs, we dig deeper.
At the end of the excavation we will fill the part closest to the surface with penetrating soil.
Drainage pipes are widely used in places like:
– Underground car parks
– Building Foundations
– Underground shelters.
In conclusion, hydrostatic stress is an issue that needs to be considered when dealing with any construction as it exists everywhere, and failure to address or give an opinion on the issue can lead to extremely serious consequences.
