The sumps and pits (double-jacketed plastic tanks) of ASIO, spol. s r.o. are made by welding structural elements and boards made of integral polypropylene or polyethylene and their copolymers, both homogeneous as well as lightweight. At the customer’s request, the plastic tanks may be equipped with technological partitions or various technological openings for the connection of pipelines.
Sumps and pits (double-jacketed plastic tanks) are normally designed as closed tanks with a non-supporting plastic lid or with a cast-iron cover suitable for walking on. The plastic tanks may be produced as food-grade tanks enabling contact with food.
The sumps and pits (double-jacketed plastic tanks) are waterproof, as defined by ČSN 75 0905. The structural design and static verification of the plastic tanks are based on the modern calculation method of end elements.

Sumps and pits and their design
The design of these double-jacketed plastic tanks combines the advantages of plastic and concrete. The basic plastic double-jacketed tank (sump, pit) makes use of the characteristics of plastic (low weight, waterproof, and chemical resistance) while also serving as the carrier for the reinforcement of the future concrete lining between the jackets. After the concreting of the inner space between the jackets, the tank acquires the static properties of concrete tanks, i.e., load-bearing capacity and resistance to soil pressure (to the length of 5 m of the footing bottom) and loading by medium-weight vehicular traffic. The plastic walls perfectly protect the concrete structure from the aggressiveness of both wastewater and groundwater.
Sumps and pits and their advantages
Quick installation without the need to use reinforcement and formwork, concrete mixture savings, guaranteed waterproof, in accordance with ČSN 75 0905.
