How to build a pit</a>

When building a garage in front of the car owner, the question arises about the inspection pit. Arguments "for" are enough.

However, despite the fact that the inspection pit greatly facilitates the maintenance of the car, the main problem that can be encountered in creating a pit is the penetration of groundwater into the garage.

Therefore, before laying the foundation with a pit, you need to measure the groundwater table.

If it is above 2.5 meters, then about the pit will have to forget.



The ideal option is to lay the pit still on the stageCreating a garage foundation. It is necessary to provide a working area, which will include a pit, and a rest area. This design will save the garage construction from excessive moisture and avoid rapid corrosion of the bottom.


The width of the pit depends on the brand of the car and directlyCommunicates with its wheelbase. The depth of the pit is laid, based on the growth of the car owner, taking into account its comfortable position in repair and preventive works. That is, add 10-15 cm to the height and get the desired parameter. The length of the pit is calculated by the formula "Length of the car + 1 meter" so that the car owner can easily enter the pit with the car installed on it.

Having made the necessary measurements, proceed to create a pit. Add to the calculated depth of 20-25 cm, to a length and width of 40 cm. Pitch the walls of the pit.


Bottom the bottom with a 10-centimeter layer of gravel, thenLayer of sand - 5 cm. Each layer is also carefully tamped, spilling water. Lubricate the resulting box with clay and lay a layer of waterproofing. Install the reinforcement and pour it with concrete, and after it has completely dried, lay the last layer of this puff cake - waterproofing.


The walls of the pit, tamped and smeared with clay,Isolate with a thick film. Next, along the entire perimeter of the walls, install the formwork with the reinforcement and, just like the floor, fill with concrete. The second option is to lay out the walls with a brick. For finishing use a variety of materials: ceramic tiles, facade plaster, fiberglass. Provide for the construction of walls ventilation opening, which will be at a level of 20-25 cm from the floor. To this hole, attach a flexible corrugated tube from the outside, which you bring to the surface and cover with a protective "fungus".


Safety harness

The design of the inspection pit should beThere is an insurance, which will not allow the car to enter it. As an insurance, use a T-shaped metal bar. It will also support the boards that cover the niche.


Warming of the pit
Think about the insulation can only afterThe pit is carefully insulated from moisture penetration. The best variant of a heater - expanded polystyrene. With a standard thickness of 50 mm, this material holds the heat perfectly, while it does not rot, does not allow water to pass through and easily adheres to the concrete. Usually, PSB-C-35 is used for the floor, but for PSB-S-25 walls.


Lighting is necessary to ensure normalWorking conditions in the pit. This can be carrying battery-powered or special lamps that feed from 36 V. In a niche, it is unacceptable to cut in an outlet that emits 220 V. This is not only a violation of SNiP, but also a real threat to life.
