The ring with bottom IDA PLAST is a monolithic concrete structure. The use of a concrete ring with a bottom will greatly facilitate the process of installing the well, as it will not be necessary to separately mount the concrete bottom, and place concrete rings on it.

When building a well, first a concrete ring with a bottom is placed in the pit, and concrete rings of the CS are placed on it. This results in an airtight and deaf tank.

Sealing rings are located between the elements of the IDA system well. They provide maximum tightness and reliability of the well.

The protective shell is made of low-pressure polyethylene (PPP) according to GOST 16338-85, designed to ensure durability (at least 50 years) and waterproofing of sewer tray bottoms and pipes during operation under conditions inside pipes of highly aggressive environment to concrete (reinforced concrete). PNT is resistant to concentrated hydrochloric, carboxylic and fusible acids, oils, fats, alkalis, salt solutions, resistant to gasoline, low temperatures, ductile and has good impact resistance.
