Calculation of a bulk floor in an industrial building
It is necessary to carry out bulk floors in a production building (energy center), in which there is a parking lot for vehicles and technological equipment installed. The area of the building is 21.5 x 11.0 m. The task for budgeting indicates the consumption of 3.1 tons with a layer thickness of 20 mm. In the estimated standards there is only a thickness of the bulk floor of 2 and 3 mm, and the indicated layer thickness of 20 mm makes me very suspicious.
Please help with determining the thickness of the bulk floor, brand, consumption and cost. The same goes for primer. Thank you in advance for your response!

Hello, Eugene.
For bulk floors of industrial buildings, a layer thickness of 20 mm is quite normal. It happens that this parameter reaches 100 mm - it all depends on the geometrical evenness of the screed, operating conditions and the load, so most likely you hurried with your suspicions about the builders.
As for the flow rate of the dry mixture, it depends on the brand of material and its density. This value ranges from 1.5 kg per 1 sq. m of epoxy up to 1.3 kg per 1 square. m polyurethane mixture with a layer thickness of 1 mm. It is possible to determine exactly how much dry matter is required to equip the bulk floor using the formula Q = S×H×Pwhere:
- S is the area of the production room;
- H is the required layer thickness;
-
P is the density of the prepared solution.
In your question, you indicated the area and thickness of the bulk floor, but did not indicate its brand and density. In addition, very often various solid fillers are added to the mixture to reduce financial costs - we simply don’t know what technology the contractor adheres specifically to in your case, so we won’t be able to help with accurate calculation of the required amount of material. Nevertheless, you can easily do the calculations yourself, relying on the above methodology and using the missing parameters.
From my own experience, even without an accurate figure, offhand, it can be said that 3 tons of material with such a thickness and area at an industrial facility is an acceptable indicator, so your fears are most likely to be groundless.
