What it is?
The collector floor slab is a square or rectangular piece of reinforced concrete. A sewer hatch needs to be installed over the circular hole in the middle of the design. Mounting loops are included with certain models.
High quality F-75 (GOST 251 92-2012) concrete is used in the construction of the structure. Hot-rolled steel is used as the material for the product’s internal reinforcement. GOST 380-71 states that the embedded elements are composed of carbon steel.
Products made with KP manifolds are marked to make selection easier.

Every value in the marking demonstrates a particular quality. As an illustration, the marking KP-12d denotes:
- KP – collector floor slab.
- 12 – internal width of this collector, in our case 12 dm = 120 cm.
- d – additional block having a width of 60, 88 cm.
Where are they used??
These components’ primary job is to shield collectors from outside pressure (soil, groundwater). The product can be used in unfavorable construction conditions because of its high characteristics.
Take note! The collectors have a longer service life if the slabs are installed in compliance with building codes.
There is active use of KP-12 products in metro tunnel construction. Prefabricated components are being used in the building of overpasses and bridges.
Collector floor structures aid in boosting the degree of thermal insulation and shield the heating mains from condensation.
Requirements for structures
Certain operational and technical requirements are placed on finished products because collector structures are constantly subjected to aggressive external influences.

Among them are:
- concrete class not lower than M300;
- mobility – P2-P4;
- waterproof. The recommended indicator is W6;
- frost resistance – F200;
- hardness – Zh3;
- strength – minimum 295 kgf/cm 2 .
Crucial! GOST 7473-2010 specifies the specifications for collector floor slabs made of reinforced concrete.

Features of application and installation

- A special feature of the operation of collector products is that structures are used deep underground, therefore they must be characterized by increased strength.
- Depending on the design features of the collector, suitable slab models are selected.
- Collector slabs can be installed in seismically unstable areas.
- If the groundwater is located high (the distance from the bottom of the collector to the water boundary is less than 1 meter), it is additionally necessary to create a drainage system.
- To drain wastewater, it is recommended to create a slope inside the collector of 2 degrees.
- To create additional strength of products, elements can be additionally reinforced using frames and a special welded mesh, which connect the slabs to each other and enhance their performance characteristics.
Advantages and disadvantages
Structures are actively used because of the many benefits of reinforced concrete products, which include:
- high strength of elements;
- fire resistance;
- long period of use;
- waterproof;
- resistance to the aggressive effects of corrosion and external factors;
- increase in thermal insulation indicators;
- frost resistance.
One of the drawbacks is the weight of the products, which increases the expense of transportation and structure installation.
