If the groundwater level in your area is high, then protect the cellar is not easy. Dear building materials (rolled glassizol, liquid glass, high grades cement, waterproofing impregnations, etc.) are required. Yes, and do it for only the experienced master. I decided to try another way. Avoid flooding helps me a small-sized submersible drainage pump. Here are some tips to those who want to follow my example.
As soon as water from the cellar goes completely, plan its reason so that he has a slope where water will be drained. Then in the low part of the cellar, cut the veil size of 30 × 30 cm and a depth of 50-60 cm. For these dimensions, make a container inside the leaf iron, inside which the pump will be. It is not necessary to apply welding, because the container should not be hermetic, the main thing is that it keeps the form and quickly filled with water. Therefore, the sidewalls and the bottom can be connected with the help of corners, bolts, brackets, etc. Next, set the capacitance in the veil to the closure with its edges or slightly lower, and then in the center put the drain pump ( what a drainage pump to choose). The calculation is simple: water flowing down the water will fill the container, and the pump pumps it from the cellar.
Pumps that would successfully deal with such work, unfortunately not so much.
