In what cases should be eliminated by the bottom of the foundation of the house
В течение 3-5 лет после постройки дома, фундамент сооружения может давать осадку. В случае если предельно допустимые нормы осадки превышены, конструктивные элементы здания начинают испытывать чрезмерную нагрузку, которая может привести к образованию повреждений. В подобной ситуации осадка уже считается просадкой и ее следует устранять.
Чрезмерная осадка фундамента здания может привести к возникновению аварийно опасных ситуаций. Признаком неприятностей обычно является разрушение или повреждение несущих конструкций дома – возникновение трещин в фундаменте, стенах, просадка плит пола, отхождение перегородок от пола или от потолка, перекос проемов и т.д.
Само по себе наличие трещин в стенах еще не говорит о том, что присутствует аварийная просадка фундамента, ведь повреждения могут касаться только финишного слоя декоративной отделки. Однако если затронуты несущие конструкции здания, необходимо провести полноценное обследование дома и его фундамента. Если выяснилось, что причиной повреждений является просадка фундамента, то устранять трещины и проводить внутренний ремонт имеет смысл только после стабилизации состояния фундамента.
Традиционный способ усиления фундамента
Классически задачу устранения осадки фундамента решали путем усиления фундамента. Вообще термин «усиление фундамента» может применяться на разных этапах возведения дома.
Когда строительство только начинается, производится просчет осадки фундамента под воздействием нагрузки на грунт. Если при просчете выясняется, что выбранная ширина фундамента недостаточна и дом оказывает нагрузку на грунт большую, чем тот способен выдержать, фундамент усиливают. То есть производят пересчет проекта при увеличенной ширине фундамента или при другом типе его конструкции.
Однако осадка фундамента может превысить допустимые нормы и на реальном объекте. И в этом случае тоже можно усилить фундамент. Традиционно это делали путем проведения серьезных земляных и бетонных работ. Нужно постепенно откопать фундамент по периметру всего здания и провести усиление отдельных участков конструкции. При классическом подходе одновременно усиливать сразу весь фундамент нельзя, и работы делают поэтапно. Учитывая немалую длительность застывания бетона (28 дней), становится понятным, насколько это сложный и трудоемкий процесс.
Усиление грунта геополимерами
Инновационные технологии геополимерного инъектирования Граундтек позволяют произвести усиление фундамента другим путем. Дело в том, что фундамент не является отдельной конструкцией, которая передает нагрузку на грунт, а существует в рамках системы грунт-фундамент.
Поэтому задачу усиления фундамента можно решить не только путем увеличения ширины фундамента, но и за счет изменения характеристик грунта основания здания. Если увеличить несущую способность грунта, то система грунт-фундамент начнет работать нормально, а конструкция и состояние фундамента при этом останутся неизменными. Таким образом, выполнив процедуру усиления грунта, можно сказать, что произошло «усиление фундамента».
Как производится геополимерное инъектирование
Чтобы остановить и ликвидировать чрезмерную осадку фундамента путем усиления грунта, под подошву фундамента инъектируют геополимерные смолы Граундтек. Проводить крупные земляные и бетонные работы при этом не нужно. А весь цикл восстановления конструктивных характеристик здания заканчивается в течение двух-трех дней.
Инъектирование выполняют через специально пробуренные скважины , в которые вставляют трубки диаметром 12 мм. В отдельных случаях возможно использование сразу двух или трех трубок в одной скважине. Трубки при этом погружают в грунт на разную глубину. Инъектирование выполняется с помощью компактных мобильных установок, без задействования большой строительной техники.

When carrying out work on the strengthening of soils, traditional methods arises an additional sediment of structures associated with technological features: excavation, drilling and a long time of the durability of materials.The GroundTek method avoids additional precipitate, since drilling is carried out by a small diameter, and the material gains strength in seconds.

Good day!
We plan to reconstruct in the company, due to serious vibration loads, there was a sediment of the floor slab.Interested in two points: Is the polymer really freezes so fast, because I would not like to slow down production.
And another moment, how much does the overall technique enter the object in the production of CMR?

Application of GROUNDTEK technologies The speed of the complete reaction of materials allows you to stabilize and vibrate the design or equipment for half an hour, while not stopping it.In most cases, the manufacturing workshop does not drive at all.The technique can be parked within a radius of up to 100 meters from the project's working area.

It rarely happens to be a strong need for drilling through the body of the foundation.In practice, the technology does not oblige unambiguously to bury the foundation itself, but obliges to get to the problem zone.If there is a way to do this without interference in the design, it will be done.

Unfortunately, it is impossible to say so.The process of change may not be linear and not flow smoothly over time.Very often, the situation changes dramatically, accumulating certain potential.We recommend in this situation to conduct surveys to determine the potential of further destruction and dispel uncertainty.

This is a heavy polymer designed for injection into the ground ground.After the injection of the polymer into the ground, it expands with controlled force and hardens, creating the necessary support to the structures based on the "modified" base.

This question will answer the instrumental examination of the foundation for the state of its condition and its bearing capacity.Visually "not beautiful" foundation may well even continue to perform its functions.Only examination and calculations can respond to your question in exactly your case.

The question is what is "critical"?Any destruction is dangerous.If the "criticality" is a threat of vital activity, that is, building standards that indicate the pre-emergency and emergency condition of building structures.But for many users, the process of starting destruction itself can mean "criticality"
