Certain areas of the concrete floor of warehouses and logistics centers can sag for various reasons. Thanks to Premium Technologies technology, it is possible to restore the required floor level and prevent cracks in the walls without vacating the area.
Concrete floors in supermarkets, warehouses and large storage facilities are subjected to daily loads, both from the regular impact of forklifts and other equipment and from the loading of shelves with goods. Exceeding the permissible loads on a concrete floor, as well as other reasons, such as movement of the base soil or erosion and weakening of the soil due to a water pipe, sewage or groundwater, can lead to subsidence of the floors in certain areas.
Such problems cause not only inconvenience in the operation of the facility due to changes in the horizontal position of shelves and racks, but can also affect particularly important objects, such as warehouse loading platforms or the floor of a store’s refrigeration chamber.
DANGER OF FLOOR SINKING
Owners of warehouses and retail premises often delay repairing sagging floors because their restoration threatens not only with direct financial costs, but also with loss of profit. After all, when restoring floors using traditional methods, long downtime of the premises is guaranteed.
Unfortunately, such negligence can end in disastrous results. The subsidence of the foundation and floor and the change in the horizontality of the racks often lead to the appearance of emergency and dangerous areas on the territory of the facility. And the situational repair of retail spaces using stands or stops that help return the racks to a horizontal position often have an untidy and unattractive appearance, which acts as anti-advertising and also indirectly leads to a lack of profit.
FLOOR LEVELING TECHNOLOGY
In order to eliminate the subsidence of the concrete floor, it is necessary to strengthen the soil and level the position of the lower floor slabs. This can be done without earthworks and without the use of heavy machinery. Geopolymer injection technologies Deep Lifting and Floor Lifting allow you to stabilize the position of concrete floor slabs by injecting special geopolymer resins, which gain strength in just 15 minutes and increase the bearing capacity of the soil to a value of 10.6 MPa.
To perform injections, it is necessary to drill several standard holes with a diameter of up to 16 mm in the concrete, which are then easily closed. Injection tubes with a diameter of 12-14 mm are inserted into the hole, through which the injection is performed directly. All equipment for carrying out the work is located in a mobile automobile complex, which can be located up to 120 m from the place of work. The material is supplied through hoses that can be placed in the aisles between the racks without the need to free the latter from goods. And the fast hardening time of geopolymer resins allows you to carry out work at night, when the premises are idle naturally. If the injection is performed during working hours, thanks to the mobility of the equipment used, it is not necessary to take the entire warehouse out of operation, but it is enough to block only one or two rows with goods for the duration of the work.
ADVANTAGES OF THE Premium Technologies METHOD
Premium Technologies geopolymer injection technologies allow real-time control of the floor level restoration process and lifting of the foundation and subsiding slabs of the lower floor to a height of up to 20 cm. At the same time, it is possible to eliminate openings due to subsidence cracks in the partitions that rest on the floor slab. Lifting control is carried out with an accuracy of ± 1 mm using special laser levels. The work can be carried out without stopping the operational cycle of the premises with savings compared to traditional methods of up to 25%.
