Europe is rich in its history and buildings reminding its culture and time periods. It's a shame that they do not always receive appropriate protection and care which they merit as a part of our history.
Restoration not only has to renew the aesthetic view but also reduce the usage of energy, to improve the climate of the premises, to enlarge the value of the buildings and improve the quality of life.
Water is considered to be the source of life on earth but at the same time it is the reason No 1 of all defects occurring in the building constructions;
When the damp level in brick construction increases 1% - thermal resistance decreases 5% !
After examining all the impacts for the buildings and their causes, we may define an appropriate conception for the restoration works, to identify an appropriate system for each part of the building taking into account both the whole and in detail.
Concrete repair is necessary when the buildings which components are concrete or ferroconcrete because of the production spoilage, in appropriative usage or environmental conditions looses aesthetic look or static function. It must be understood as concrete or ferroconcrete durability and functional recovery and which requires substantial technical knowledge and understanding of materials.
Concrete is unstable building material. It is negatively affected by many internal and external factors. These factors become more and more dangerous when we speak about reinforced concrete. At the presence of different nature effects different methods of concrete reconstruction must be applied.
The main stages of concrete repair:
- preparing the ground
- anti-corrosion coating of armature
- concrete surface roconstruction
- protection from harmful influences
Taking into consideration the level of damages, existing environmental conditions stating what qualities the concrete must gain the most effective and economic reconstruction type is chosen.
JSC "Immo-Invest" represents German company TPH-Bausysteme GmbH and Austrian company Rofix AG and can therefore offer a wide range of production for concrete repair and protection works which may be applied for different industrial branches.
Injection as a term in construction field must be realized as thick materials' injection into cavities and cracks in the premises or grounds in order to fill them, reinforce or waterproof..
Water pouring through the leaking joints in concrete, foundation blocks or the cracks to the inside of cellar or underground parking makes much trouble for the building owners. Usual applying isolation from inside often is only the temporary solution of the problem, postponing it for the later time. We assure long-term tightness even in dynamically exposed buildings while injecting elastomeric tars to leak locations using special technique with the high pressure support. We may ensure it with the help of our experience because the first objects were injected ten years ago.
Air and water enter though every crack in ferroconcrete construction. In the crack's place armature is not protected by alkaline concrete medium and as the result of it begins to corrode and this significantly shortening construction's life. In accordance with EU norms >0,2 mm width crack is considered dangerous for the structure. In order to fill in such cracks we can inject low viscosity duromeric tars or mineral suspensions which not only fill in the crack but also stick the structure. Cracked lintels, columns, floor structures are often occurring cases requiring a reliable adhesion in full width of the crack and that is guaranteed only by a professionally conducted injection.
Moisture rising by the capillary depleting finishing layers of the buildings plinth part also may be blocked with the help of injection. As it is known, the damp wall has significantly lower thermal resistance and forms a very favorable medium for growth of various fungus and mould. Subject to many factors we suggest for the solution of this problem injections with the hydrostructural tar or micro emulsions. They are often combined with the injections of limy solutions in order to fill in all cavities and cracks.
In addition to the above mentioned most frequent cases we may also offer more complicated ground stabilization, isolation behind the wall, suspension of the under pressure water, brick walls in entire area sealing and other works accomplished with the help of injection.
Referring to long years experience we have all necessary equipment to accomplish all types and manner injections. In Lithuania we represent the largest injection equipment manufacturer, German Company DESOI GmbH, professional injection materials producing companies TPH-Bausysteme GmbH and Wacker AG, because of it we are in lead position in this field in Lithuania.
