How to build a viewing hole

How to build a viewing hole

During the construction of the garage before the car owners there is a question about the observation hole. Arguments "for" enough.

However, despite the fact that the inspection hole facilitates maintenance of the car, the main problem that you may encounter when you create a hole - a penetration of groundwater into the garage.

Therefore, before laying the foundation to the pit is necessary to make metering of groundwater level.

If it is higher than 2.5 meters, it will have to forget about the pit.

instructions

1

Ideal - the pit lay at the stagecreating a garage basement. It is necessary to provide for the working area, which will include a pit, and a relaxation area. This design allows the construction of a garage to protect from excessive moisture and avoid emergency underbody corrosion.

2

The width of the hole depends on the brand of car, and directlyIt binds to its wheelbase. The depth of the pit lay the basis of motorist growth given its comfortable position for repair and maintenance work. That is, add to the growth of 10-15 cm and get the desired setting. pit length is calculated according to the formula "length of car + 1 meter" to the car owner could easily go into the pit when installed on her car.

Making the necessary measurements, proceed to the creation of the pit. Add to the calculated depth of 20-25 cm to the length and width of 40 cm. The walls of the pit tamp.

Floor
Bottom pour a 10-centimeter layer of gravel, thensand layer - 5 cm. Each layer also carefully tamp, spilling water. Lubricate the resulting clay box and place a layer of waterproofing. Set rebar and pour concrete, and after its complete drying lay the last layer of puff pie - waterproofing.

Walls
The walls of the pit, rammed and plastered with clay,isolated thick film. Further around the perimeter walls to install the formwork and reinforcement as well as flooring, concrete fill. The second option - to lay out a brick wall. To finish use a variety of materials: ceramic tiles, facade plaster, fiberglass. Provide in the construction of the wall vent, which will be located at the level of 20-25 cm from the floor. By this opening, attach the flexible corrugated pipes outside, which brought to the surface and cover with a protective "fungus."

a safety rail

The design of the observation wells must beIt provided insurance, which does not allow the car to drive it. As insurance, use a metal rail T-shaped. She will support boards that cover the niche.

Warming of the pit
Think about warming can only be afterpit carefully insulated against moisture. The best option of insulation - polystyrene. In a standard thickness of 50 mm, the material holds heat well, it does not rot, it is waterproof and easy to apply to concrete. For the floor usually used PSB-S-35, and the wall PSB-S-25.

Lighting
Lighting is necessary to ensure normalworking conditions in the pit. It may be carrying, running on battery power or special lights powered by 36 V. In the niche is unacceptable infeed socket, issuing 220 V. It is not only a violation of SNIP, but also a real threat to life.
