After the pit dug, you can start concreting.First, you must seal the bottom of the pit.This can tamp the gravel in several layers.Gravel mound should be more than 10 centimeters.If t
he soil has a high moisture content, the bottom of the pit is necessary to begin to cover the clay.Clay is also necessary to tamp.Above the clay is poured gravel.A layer of gravel should be covered with a layer of sand, about 5 centimeters thick.

Then proceed to the preparation of the walls of the future viewing hole.Clay pit wall to be treated.So, create a clay zamoy who will enter the water in the pit .Then we engaged in creating a waterproofing bottom.You will need a plastic film.Next, you need to concrete inspection pit bottom.The layer of concrete should not exceed 10 centimeters.

wait, when there will be a complete solidification of the floor and set the formwork around the perimeter of the future walls of the pit.The walls of the pit must be strengthened reinforcement.Thereafter, they will be more reliable.With rendered monolithic formwork anchors on the floor of the garage, you must install a metal frame.Fill between the formwork and the concrete wall of the pit.It must at the same time compacted.Inspection pit ready.

Warming pit
think of insulation only after the pit carefully insulated against moisture.The best option of insulation - polystyrene.In a standard thickness of 50 mm, the material holds heat well, while not rot, is waterproof and easy to apply to concrete.For the floor usually used PSB-S-35, and the wall PSB-S-25.
7
Lighting Lighting
necessary to ensure normal working 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.
