Strengthening and stabilizing the banks of water bodies
Premium Technologies geopolymer resins are a material that does not come into contact with water and is able to maintain a stable state in a humid environment. This makes it possible to use geopolymers to strengthen the shoreline of water bodies and strengthen the soil of the coastal zone. Water erosion – gradual destruction due to the continuous influence of liquid – can be exposed not only to the shores of large lakes, seas and rivers. No less dangerous for coastal soil, and therefore for neighboring buildings, are illiterately equipped reservoirs, wastewater receivers, small lakes with underground springs, weakly fortified dams, etc. To prevent the occurrence of emergency situations that threaten the breakthrough of fortifications or the collapse of the soil of the coastline, it is necessary to strengthen the coastal soil and strengthen the shore of the reservoir. TRADITIONAL COMPLICATIONS When the threat of coastal erosion is not a priority, shore restoration and reinforcement of damaged soil can be carried out on a residual basis. For example, due to the impossibility of carrying out a complete reconstruction of the fortifications, temporary solutions are used (for example, periodic reinforcement of the soil with crushed stone). Such an approach in the long term turns out to be long, laborious and expensive. This requires the use of heavy construction equipment and extensive excavation work. When using Premium Technologies geopolymer resins, a one-time capital solution to the problem of soil reinforcement is possible. Restoration of soil properties using geopolymers is carried out quickly and efficiently, involving compact mobile installations that introduce multicomponent geopolymers through small holes with a diameter of 8-16 mm. SOIL REINFORCEMENT TECHNOLOGY To strengthen emergency sections of the coastline and restore destroyed shoreline fortifications (for example, bulk stone dams) using geopolymer resins, the Deep Lifting injection method is used. Geopolymer injections are carried out to a depth of 1.5 m or more. In this case, a series of several injections at different depths makes it possible to form a powerful waterproof screen directly in the soil. Multicomponent geopolymer resins gain strength within 15 minutes after the injection is completed and immediately create a waterproof barrier capable of withstanding a multi-ton load. The structure of geopolymers provides the fortification with waterproofing and waterproof properties and allows it to maintain a stable state in humid and water-saturated environments for a long time. To strengthen the structure of the shore, injections can also be carried out into the existing coastline formed from stones and boulders. In this case, the geopolymer resin will gradually fill the space between the boulders, resulting in the formation of a monolithic massif. FEATURES OF GEOPOLYMERS Increased humidity does not affect the quality of the hardening of Premium Technologies. In addition, geopolymer resins are a completely inert and environmentally safe material. Its use does not disrupt the biological balance in water bodies.
Leveling and stabilization of the railway track
Thanks to Premium Technologies geopolymer injection methods, it is possible to eliminate subsidence of railway ballast, as well as stabilize concrete slabs of railway crossings, tunnels, stations, stations or depots without changing the train schedule. Railway infrastructure facilities include not only sections of the tracks themselves, but also a wide range of elements of the transport system. These include railway bridges, tunnels, stations and stations, depot premises, facilities for repair and maintenance of warehouses, etc. All of them experience regular operational loads, as well as the influence of the environment and groundwater. The design of railway tracks involves the arrangement of a ballast layer of crushed stone or other bulk material, on which the rail pair is laid. Long-term operation of the track leads to the fact that in some sections of the railway track, ballast subsidence occurs, which changes the position of individual rails. When the rail subsidence exceeds the permissible value, the risk of emergency situations increases. Thanks to Premium Technologies technologies, subsidence of individual sections of the rail track can be eliminated in just a few hours without dismantling structural elements. STRENGTHENING OF RAILWAY BALLAST To strengthen the soil at the base of the railway track and eliminate ballast subsidence, it is not necessary to dismantle the rail pair and carry out backfilling and strengthening of the ballast. When using Premium Technologies methods, it is enough to make several injections of geopolymer resins under the ballast or into the body of the ballast prism. The gradual introduction of geopolymers will fill all cavities and voids, and then the uniform expansion of the geopolymer material will create the necessary vertical pressure and eliminate rail subsidence. STABILIZATION OF REINFORCED CONCRETE PLATES On some sections of railway tracks, primarily at level crossings, as well as in tunnels, at railway stations, stations or depots, rails are laid on reinforced concrete slabs. Here, subsidence of individual slabs is also possible. This often occurs due to disruptions in the operation of drainage structures, when soil erosion begins under the reinforced concrete and cavities and voids are formed. In this case, it is necessary to strengthen the soil and stabilize the position of concrete elements. Premium Technologies technologies allow this to be done without dismantling the slabs and rails by injecting geopolymers under the reinforced concrete slab. Two geopolymer injection technologies are used for this. In order to strengthen the soil at a great depth under the railway track, geopolymers are injected using the Deep Lifting method. And for direct alignment of concrete slabs, the Floor Lifting technology is used. FEATURES OF GEOPOLYMERS INJECTION To deliver geopolymer material to the required depth, it is necessary to drill a well in the ballast of the prism or in the reinforced concrete coating. Injections are carried out through special tubes with a diameter of 8-14 mm, where geopolymers are supplied through hoses. The rise of reinforced concrete structures and sections of the rail track is controlled using laser levels. It is noteworthy that the geopolymer fills voids, structures, forms the necessary vertical pressure and gains 90% strength in just 15 minutes. This allows the repair of the railway coating to be carried out as quickly as possible and without disrupting the schedule of regular transportation.
Lifting the foundation and floor in private homes
Foundation subsidence, which often manifests itself in the form of deformation and subsidence of individual sections of the first floor floor, often leads to cracks in the floor and walls. Dangerous damage to buildings can be avoided as soon as possible by strengthening the base soil and stabilizing the foundation using Premium Technologies techniques. The reasons for the weakening of the foundation soil and the gradual subsidence of the foundation of a private house can be different. Most often, such problems arise due to loosening or poor-quality preparation of the soil under the foundation. It is also possible to simply ignore the need to conduct survey and geodetic work during construction, as well as weakening of the soil and further subsidence of the foundation due to a breakthrough of a water supply or sewage system, the action of groundwater, the destruction of underground tanks, and so on. If the situation becomes more complicated and the degree of subsidence of the foundation increases, gradual damage to the supporting and non-supporting structures of the building, skewing of windows and doorways, disruption of thermal insulation and, as a result, the slow destruction of the entire house is possible. In order to stop subsidence and stabilize the foundation, it is necessary to urgently strengthen the foundation soil, and then lift and stabilize the foundation, and at the final stage – leveling and restoring the floor. FOUNDATION AND FLOOR RAISING Thanks to the application of the Deep Lifting geopolymer injection technique, the foundations of private and multi-storey buildings can be lifted without any destruction. The fact is that for the injection of Premium Technologies geopolymer resins, there is no need to involve massive equipment for earthmoving or concrete work. Deep injection of Premium Technologies geopolymers makes it possible to strengthen soils and increase their bearing capacity. As a result of injection to a depth of up to 10 m, the foundation is raised to the desired level with an accuracy of ± 1 mm. The work is monitored using high-precision laser levels in real time. The maximum height of the foundation is raised to 20 cm. In this case, the injection is carried out directly under the foundation sole. In some cases, after the completion of operations to strengthen the base soil and raise the foundation, the first floor floor slabs are leveled. Here, the restoration is carried out using Floor Lifting technology: geopolymers are injected directly under the concrete base slab. For this, holes with a diameter of 8-16 mm must be drilled in the slab, which are simply closed after the work is completed. ADVANTAGES OF THE Premium Technologies METHOD The structure of Premium Technologies geopolymer resins allows you to perform foundation lifting and floor slab leveling work at any time of the year and in any weather, day or night. At the same time, thanks to the mobility and compactness of the equipment used, the work is carried out without the relocation of residents. The material used for lifting the foundation and floor slabs is environmentally friendly, stable for a long time, harmless to plants, animals and people. It does not pollute the soil and the environment, does not react with water and has waterproofing properties. Due to the fact that geopolymer resins gain strength just 15 minutes after injection, foundation stabilization and floor slab lifting in private homes can be completed in an average of 2-3 days. At the same time, cost savings compared to traditional technologies reach 25%.
Repairing cracks in the floor and walls of private houses
Unfortunately, the formation of cracks in the floor and walls of private houses is not a rare phenomenon. Most often, such deformations occur due to subsidence of the foundations of buildings, which can be provoked by weakening of the foundation soil. It is possible to restore a house with damage of this nature using the Premium Technologies geopolymer injection technology. Despite the fact that the house seems to us to be a solid structure, its position in space can dynamically change due to changes in the characteristics of the soil on which the house is built. The fact is that the foundation of the house, and therefore the entire structure, can be subject to uniform settlement or uneven settlement, when for one reason or another the settlement in adjacent areas of the foundation is different. When the degree of settlement of the foundation exceeds the limit value, the load-bearing and non-load-bearing structures of the building are damaged. This is manifested in the formation of cracks in the floor and walls, the departure of load-bearing walls from the ceilings, the skew of doorways and window structures, and so on. There can be several reasons for such subsidence of the foundation. These are both design errors and poor-quality construction work on compacting the soil of the foundation base. Force majeure situations are also possible, when the soil of the foundation is weakened due to a violation of the integrity of the underground water supply or sewage system or a sudden increase in the groundwater level. In any case, to prevent further destruction of the house and to eliminate cracks in the walls, it is necessary to strengthen the soil and raise the foundation of the house to the desired level. METHODS OF SOIL STRENGTHENING AND FOUNDATION RAISING The traditional method of strengthening the soil of the base and raising the foundation of the building involves the implementation of large-scale work. In this case, to eliminate cracks in the floor and walls, it is necessary to involve serious construction equipment. In this case, the full period of repairing the foundation, strengthening the soil and restoring the floor and walls of the house can take about 4-6 weeks. Modern methods of soil strengthening, stabilization and lifting of foundations of private houses, which involve the introduction of a base of multi-component geopolymer resins Premium Technologies into the soil, are able to solve such problems within just 2-3 days. At the same time, there is no need to carry out earthworks and involve heavy special equipment. GEOPOLYMERS INJECTION To eliminate cracks in walls and floors using Premium Technologies technology, geopolymer injections are made either to a considerable depth under the foundation base (Deep Lifting technology) or directly under the concrete floor slabs (Floor Lifting technology). The expansion of the geopolymer material gains strength in 15 minutes, which allows you to quickly fill the voids in the soil under the foundation and increase the density and bearing capacity of the base soil. It is very important that the structure of geopolymers makes it possible to carry out injections, including in excessively moist soils. During the injection process, Premium Technologies specialists are able to track the movement of concrete floor slabs and foundations in real time with an accuracy of ± 1 mm. Cracks are eliminated literally before our eyes. The injection procedure itself consists of drilling small holes or holes in the concrete floor. The diameter of the injection holes is usually 8-16 mm.
Leveling the floors of warehouses and stores without stopping their work
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%.
