What if flooded basement?

readership FORUMHOUSE well aware that cellar construction or basement - responsible action requiring competent calculation. Despite a number of benefits to be gained from the device space "0" level, their operation may be complicated due to the high groundwater level. So think about how to drain water out of the basement, it is necessary at the stage of its design.

However, even if you have already built a basement floods on a regular basis, it's not a reason to give up. Practice Site users said that there is always a way out!

Fresher (Participant Portal):

- I dug under the house basement depth of 2.7 meters. The floor in the basement of the earth. Geological surveys have shown that the groundwater level is below the foundation base. Each time after heavy rains flooded basement water. If it does not pump out, it turns out the real pool 1.5-1.7 meters deep. Water seeping between the slits of the foundation blocks at a depth of -1.5 meters from ground level. Basement waterproofing done, but apparently it is not effective, but the gutter yet. I think we need to do drainage.

Most often, the following scheme is proposed to solve this problem:

1. Fully dig the basement around the perimeter.

2. Do additional waterproofing the basement walls.

3. Arrange a drainage system at the level of foundation base.

4. Make a clay castle.

Despite the apparent universality of this decision, the practice shows that there are no schemes, suitable for all situations.

Selection method drainage system device depends on the data obtained in the study on the hydrogeological portion.

Evan(Participant Portal):

- First we need to understand what kind of water flooded the basement: dirt or perched.

This is done so - 2-3 drilled hole depth of 2-3 meters below the level of the basement box.

Then look at what level will the water in the wells, and whether it will be above or below the level of the foundation. Perched usually collected in the ground, applied backfill sinuses foundation.

Therefore, drainage and waterproofing should be considered together, the one without the other does not.

Drainage system cuts off the water from the basement walls, and waterproofing is moisture inside.

It is also necessary to withdraw from the base water coming from the roof, when melting snow, which is arranged otmostka mounted catchment system and arranged livnovka.

On the right the cake warm otmostki gives detailsin this article.

If these measures do not help, you have to do trim drainage, and water collected in the basement, pumped through the pit.

Dodge45(Participant Portal):

- I have a house there is a basement. Each weight of its floods. Water - about 20 cm from the bottom of the basement level. So I decided to drain it by organizing a pit, where going to the water, which can then be pumped out.

Pit forumchanin did so: took an aluminum tank for 500 liters and cut it in half. The result was a container with a bottom, a height of 1.7 meters and a diameter of 90 cm. By the bottom of the tank Dodge454 screwed corner that favor the capacity size. They serve as an anchor and does not allow the tank to float. Then, the bottom of the tank, in a circle, forumchanin nasverlil plurality of holes 20 mm in diameter. They are necessary for better water harvesting.

The next step was digging in the basement pit depth of 1.5 meters with the distance from the wall 2 meters.

Dodge45:

- Dig a hole, I put it in the tank and fell asleep pit with a capacity of granite rubble fraction 3-7 cm.

The user then dug trench two inclined to the pit, with a height difference of 60 cm to 100 cm. Sprinkle bottom of trenches granite gravel, laid sewer plastic pipe with a diameter of 150 mm prosverlonnymi discordantly holes 13 mm in diameter and sleep trench rubble. We turned drains. The barrel set forumchanin pump for pumping the collected water. It then merges into a roadside stream.

Schedule lowering the water in the basement:

• 2006 The pump is switched every 20-30min.
• 2007 The pump is switched every 1 h 30 min - 2 h 30min.
• 2008 The pump is switched every 2 h 30 min - 4 hr.
• 2009. The pump is switched every 4 h 30 min - 6 hr.
• 2010 The pump is switched every 6-12 hours.
• 2011 The pump is switched on only by force. The water level on the bottom of the barrel is stable - 6 cm.

A year forumchanin buried under the road pipe, which has paved the sewer plastic pipe of 150 mm diameter and made of stainless steel in receiving well for draining water from the pit.

Dodge45:

- Humidity in the basement is 73%. Now you can store everything that previously had to be stored in the cabins: tools, building materials, food supplies. Also in the basement is worth pumping station and gasoline generator.

Another variant of the pit to drain water from the cellar

da4hik(Participant Portal):

- GWL in my area - at bayonet spade, under the house - an aquarium, because the foundation of almost all filled with water. To pump it all the time the pump is expensive. So I made drainage.

Drilled in the housing a plurality of apertures for water drainage, while at the bottom of the tank secured a siphon from the kitchen sink with a pipe diameter of 70 mm. Then da4hik prokapat under fundamentomtransheyu sloping towards the storage pit present in the distal end portion.

The drain trench brought plastic pipe of the pit. Instead of a perforated drainage pipe wrapped in geotextile, on the advice of neighbors forumchanin sketched on the trench bottom trunks felled trees. The water collected in the storage tank in the basement, according to the natural slope is discharged through a drainage ditch outside the area.

da4hik:

- So I'm not only removed the water from the house, but also partially drained site.
