The concrete floor of the first floor of utility and production premises may begin to sag. Deformation and skewing of individual concrete slabs, damage to concrete elements at joints, etc. are also possible. To repair and level the concrete floor, it is not necessary to interrupt the production process and dismantle the equipment.
If the floor of the first floor of a utility or production premises is made of concrete slabs, subsidence of individual elements is permissible within certain limits. All preparatory work when arranging the floor must be done at a high level, otherwise after some time of operation the premises will require repair of concrete floors. Heavily subsided and unstable concrete elements, as well as sagging or damaged edges of the slabs will interfere with the normal course of production processes.
CONCRETE FLOOR REPAIR
To eliminate the deformation of the concrete floor, to raise and level the position of individual concrete slabs of the first floor floor, it is possible using the Floor Lifting technology. The work can be carried out in the shortest possible time, without dismantling the equipment. This saves time and money, which is impossible when using outdated methods of repairing concrete floors.
At the same time, when repairing concrete floors using the Floor Lifting technology, the load on the concrete floor is not a disadvantage, but rather an advantage. Sometimes it makes sense to first install new equipment, and only then perform work on correcting the level of the concrete floor. With significant weight loads, it is easier to direct maximum efforts when injecting geopolymers into lower soil layers. The soil is compacted under a given load, which will allow you to obtain a more stable floor surface.
CONCRETE FLOOR LEVELING TECHNOLOGY
When repairing a concrete floor using Floor Lifting technology, problem areas of the floor can be put into operation as quickly as possible. Downtime and costs associated with removing and replacing concrete floors are virtually non-existent. And the technology itself has minimal impact on the customer’s business processes.
In order to align the horizontal position of the concrete slabs, a series of geopolymer injections are carried out directly under the slab through holes with a diameter of 8-12 mm. The constituent components of the material are mixed on special equipment, the chemical reaction of the expansion of geopolymers begins almost instantly. The geopolymer material fills cavities and voids, expands and compacts the weak bearing capacity layers of the soil under the slab.
Soil compaction occurs within a radius of 0.50 m from the injection site, and with the further introduction of geopolymers, a layer with bearing capacity is formed, which becomes a support point for lifting the concrete floor slab. The lifting process is controlled and monitored during the work. The lifting accuracy is ± 1 mm. After the work is completed, the injection holes are closed.
REPAIR OF COLD ROOM FLOORS
Special requirements are made for thermal insulation of refrigerated warehouses. In order to maintain a sub-zero temperature inside the room, such structures are specially insulated on all sides, including not only the walls and ceiling, but also the floor.
If it is necessary to convert an existing warehouse into a refrigerated warehouse that is not equipped with reliable thermal insulation, geopolymers can also be used to level and insulate the floor or concrete slab foundation.
During injection, two tasks are solved here. First, the soil is strengthened and compacted, which makes it possible to prepare the floor of the first floor for increased loads. Secondly, an additional layer of geopolymers under the foundation or floor of the first floor acts as a thermal insulation material. In this case, there is no need to incur additional costs for arranging thermal insulation of the floor of the refrigerated warehouse.
