Bottom slabs – to create a reliable foundation.

What elements are used in the installation of well structures:

Additional rings – to obtain the required well size if it is not possible to create it from standard products.
Floor slabs (also known as well covers) – for covering the top of the well and the space under the hatch.
There are also rings with caps, which are a combination of a ring and a cap into a monolithic structure in a factory environment.

Well covers
The cover is a round plate that covers the ring, with a hole in the center or on the side. In drainage wells, covers are mounted with a hole for the hatch in the center, for other purposes - on the side.

The covers are made of heavy high-strength concrete of at least class B15, waterproof and frost-resistant. For installation and loading/unloading, the product is equipped with reinforcement loops.

Bottom plates
These are prefabricated reinforced concrete elements for the skype data of underground engineering structures and communications. The slabs become the base for the chamber, and rings are mounted on top of them. Thanks to the bottom slabs, it is possible to ensure the tightness of the well and protect it from destruction, moisture ingress and soil collapses. Before choosing a bottom slab, you need to know how much the concrete ring weighs in order to correctly calculate the load.

Bottom slabs are a round product with the diameter of the well. They are made of concrete with frost resistance of at least F100, water resistance of at least W6, strength of B15 and higher.

Support rings
These are special elements on which the manhole hatch rests. The products are round in shape according to the outer diameter of the manhole, of small thickness with an inner opening diameter of at least 70 centimeters, so that a person can get inside if necessary. The weight of the concrete ring is about 50 kilograms. Concrete meets all requirements and standards.

Rings with caps
Such products involve combining two elements - a ring and a cover - in a factory environment. A finished product is delivered to the facility, replacing the other two.
