Comparison of cementing technologies and grained
In comparison with the injection of cement (or silicate) solutions in the base, technology Граундтек has elasticity in the approach and project implementation, which is a serious advantage. When the volume of the ground array is changed (depending on the moisture content), the cement solution crumbs or at all "not seizing", losing its properties. The discharge of cement solutions is useless for alloying soils and soils with a high content of organic substances. In turn, silication in such conditions is applicable. Depending on the degree of acidity of soils and their, the time of setting concrete mixtures and silicate solutions may be an unpredictable value. Cement solutions are subject to negative impact of shock and vibratory loads, developing into the construction trash. Граундтек deprived of all these shortcomings, because It is elastic and does not interact (it is not subjected to significant influence) with the chemical medium of the base grounds.
Technological Advantages: Strong>
- Все компоненты, необходимые для реакции, смешиваются при инъектировании;
- Время реакции предсказуемо и контролируемо;
- Процесс реакции не зависит от внешних факторов.
The soil layers are subject to expansion and compression when the content of moisture in them (and its aggregative state) is changed.When the foundation is enhanced by concrete, a rigid structure is formed, which begins to rise and fall into periods of changes in the degree of water saturation.In the process of constant vertical and horizontal primers of the soil, crack arise and the integrity of the base structure is destroyed.The inhomogeneity of the soil layers even more enhances the dynamics of the destruction of the object.
Silication and the discharge of cement solutions is prohibited in some types of soils, for example, in loss, due to the presence of water in these soils, which makes it impossible to gain the required properties of the required properties.Depending on the chemical composition of soils, silicate and cement solutions may not gain the required strength and turn into a pulver, which will further worsen the carriers of the soils.
Advantages of cementation (and silication, as related technologies according to work technique): strong>
- Это традиционная инженерная техника
- Она имеет широкое инженерное применение, из-за высокой степени опробирования технологий
Cement deficiencies (and silication): strong>
- Это может быть медленный процесс, поскольку результат не предсказуем даже после утверждения проекта.
- «Грязные» технологии в виду технологических особенностей. Частое возникновения аварийных ситуаций. Это трудоемкий процесс, который требует наличия большого количества времени, персонала и серьёзной техники.
- В глинах и иных подвижных либо изменяющихся со временем грунтах она не применима, так как по сути не решает причину проблемы.
- Не применима в водонасыщенных основаниях.
- Не способна к предсказуемому выравниванию и подъёму конструкций.
decision Граундтек: strong>
This is a more modern, but still a proven method for strengthening the foundations and bases of buildings (since 1978). It includes the injection of an ecologically neutral resin under the foundation in the base through small holes (8-28 mm). The resin is supplied to the ground and expands as it harvested. It also fills emptiness and cavities. In the process of how the injections of the resin continue, it will finally raise the house or design above. The process is carefully monitored by practitioners that control injections with special highly sensitive laser instruments. The resin formula is carefully selected in accordance with unique weather, soil conditions and facing engineers.
Advantages Граундтек: Strong>
- Односторонняя проектная заменимость с цементации на Граундтек без потери качества
- Чистота и опрятность: нет необходимости в раскопках, что означает отсутствие грязи и отходов
- Оперативность и быстрота: большинство проектов, завершается в течение двух-трёх дней
- Клиент может продолжать использовать объект во время работ.
This is more than a 40-year-old world-proven method of strengthening foundations and grounds for protecting the future of your most important asset.

What about comparing the characteristics of concrete and your polymer?Can he replace concrete?
Aleksandr Efimchik (inzhener GROUNDTEK) Nov. 21, 2020
In the new construction, concrete is treated with something will replace.At least in the foreseeable period.But in the question of repair and reconstruction, polymer technologies have long been bypassed concrete technologies due to their flexibility, predictability and convenience at all stages of project implementation.As for the characteristics, the polymer is able to gain compression strength to 10 mp, despicable, in principle, it is not capable of significant expansion, not to mention the predictability of hidden work.

Tell me, but the distribution of your material is really controlled?Because when my neighbor was strengthened with the help of cement, I have in the garden at a distance of 4 meters from the house of the neighbor, the hills began to climb ... the spectacle is still.
Evgenij Novitskij (inzhener GROUNDTEK) Oct. 16, 2020
Yes, the spread of the material is controlled, in contrast to cement.It's all about the method: cement - swing under pressure and it flows from the region more pressure into a lower pressure area in a semi-liquid aggregate state.The material of the YurgrandteTektka creates pressure itself at the injection site, it in principle cannot lean, since it is only a liquid state in the tube, and then it is an expanding and hardening substance.

Good day, how is the calculations for the number of material and what documentation is your technology certified in the territory of the Russian Federation?
Aleksandr Efimchik (inzhener GROUNDTEK) Nov. 28, 2021
All calculations are carried out by qualified geotechnical engineers who trained abroad.On the territory of the Russian Federation we are based on the "Standard" developed by NIRP them.Hersevanova issued after testing and adapting technologies in the Russian Federation.

And if you make a strengthening of the house, then it is necessary to process the entire perimeter of the building to handle or can only handle cracks?
Skvortsova Nadezhda· Nov. 28, 2021
Is this material that will be under home is not harmful?After all, living with him.
Pavlov Aleksandr· Dec. 13, 2021
Cement here is the body of the foundation to strengthen ... How are your materials with this?
Aleksandr Efimchik (inzhener GROUNDTEK) Dec. 13, 2021
This is possible and there are resin-designed specifically for these purposes, however, it is worth noting that this is not our specialization.The question is that if the foundation is in the ground, then this is our specificity and we can strengthen it according to a special injecting scheme.
Kuz'mina Olesja· Dec. 21, 2019
The financial component of course a lot of important factor in choosing technology, however, I want to say that the cleanliness and speed of work, and the most important result, for me personally played a key factor when choosing GrUNDTEK technology.
I am very pleased with the work performed.
Terehova Alla· Nov. 15, 2021
We practice in practice with the lack of results by cementation, made us work on the strengthening, the controlling organization tried to cut the cores in the places of strengthening, and everywhere in prototypes something similar to the pulp liquid, perhaps the gain method was incorrect, since he could have heard that the flooded soils should be servedThe dry mixture, but nevertheless in empty discharged money.
Scherbakova Milana· Oct. 13, 2020
How much is this method more expensive cementation?
L'vov Mihail· Dec. 18, 2020
And you can experience the result after the cementation?Curne will answer questions?
Kalashnikova Alla· Nov. 24, 2020
Good day, is it possible to produce your work after unsuccessful cementation, if at the same time the cement grabbed, and the sediment continues?
Starikova Alla· Nov. 22, 2019
When comparing two technologies, I can say that your technology is more efficient.
Although, if the strengthen is required at the stage of preparation of the soil under the foundation, here is certainly a controversial question ...
Kuzina Galina· Nov. 22, 2020
Hello.And were there any attempts to mix the polymer and concrete, and what did this lead to?
Frolova Alla· Nov. 17, 2021
And the replacement of the project from cementation on the polymer is easy?And for examination?
