Repair and waterproofing of underground structures

Геополимерные смолы дают возможность их применения для гидроизоляции и укрепления подземных сооружений. С помощью геополимеров можно гидроизолировать и восстанавливать подземные емкости, колодцы, коллекторы, топливные баки, трубопроводы, шахты, подвалы и другие конструкции.

Во время использования подземного сооружения, которое должно обеспечивать полную герметичность, возможно возникновение микротрещин с дальнейшим проникновением в них технологических или почвенных жидкостей. Во многих случаях срочный ремонт конструкции, замена поврежденных элементов и заделка трещин не может полностью вернуть гидроизоляционные свойства. Ведь появление трещин могло спровоцировать изменение характеристик грунта, в толще которого расположена конструкция.

Если стенки подземного сооружения начали пропускать жидкость, грунт, скорее всего, испытал ослабление, размытие и уменьшение уплотненности. В таких ситуациях кроме заделки трещин и восстановления характеристик объекта, нужно также укрепить и усилить грунт. Сделать это можно, повысив его уплотненность с помощью геополимеров Граундтек.

Особенности геополимерных смол

Важное преимущество геопролимеров Граундтек в том, что этот материал не вступает во взаимодействие с водой. Геополимеры просто вытесняют воду в окружающее пространство. При инъектировании геополимеров в ослабленный влагонасыщенный грунт, вода из него уходит, а сам грунт усиливается и уплотняется.

Кроме того, способность к водопоглощению усиленного и уплотненного геополимерами грунта снижается, а в качестве дополнительного эффекта от применения геополимеров происходит гидроизоляция стенок конструкции в местах, куда была совершена инъекция.

Обработка стенок шахт и туннелей

Нередко туннели, трубопроводы, шахты и другие подобные конструкции делают из сборных элементов. Чтобы гидроизолировать поврежденные элементы такой конструкции и заделать швы и стыки между сборными элементами, можно использовать геополимерные смолы. Их инъектируют в грунт, который сопрягается с местами повреждений и стыками между элементами.

Осуществлять инъектирование можно и с поверхности земли без раскопки поврежденной конструкции, и прямо изнутри туннеля или шахты (если есть такая возможность). Во время инъектирования, геополимерный материал может даже попасть в пространство шахты или туннеля, что будет свидетельствовать о качественном выполнении работ. Лишний материал нужно будет просто срезать с внутренних поверхностей.

Снижение влагоемкости грунта

Другая причина ухудшения гидроизоляционных характеристик таких подземных сооружений, как подвалы, фундаменты и т.д. – некачественное уплотнение грунта обратной засыпки, прилегающего к стенкам конструкции. Такой грунт становится более влагоемким, чаще намокает, что приводит к непрерывному воздействию влаги на стенки сооружения.

Этот процесс можно остановить, если уплотнить грунт, выполнив инъектирование геополимерами. При инъектировании геополимерами влагоемкость грунта снизится, а косвенным следствием будет гидроизоляция сооружения.

Unfortunately, there is incorrect understanding of the conditions in which similar materials are effective.If the design is experiencing a plugness out of out, then impregnating the design from the inside you do not squeeze the moisture out and stop its arrival.Fracting under such conditions you will regularly get leaks as the moisture will deform the design over time and finds new ways of receipt.Therefore, for a radical solution, it is necessary to provide measures to block the income of moisture from outside.Groundtek compounds are just performing this feature.

Materials have different nature and properties.For the task of filling the empty containers of various contents, there are a number of materials that have enormous potential to expand and absorb not only liquid substances, but also odors in closed cells of the final composition.This task is solved without unnecessary headaches.

The material is selected individually for the task, taking into account all the requirements for expansion, fluidity, expansion volume and strength of resistance to compression.Therefore, the risk exists a plot of material into damaged pipes.Therefore, a very important part of the project implementation is a survey and collecting the maximum amount of data for a guaranteed solution with minimal risks.

With a general approach, there are two options.The number one is the water supply so that the groundwater does not blur the base.The number two is to create a non-blurred base under the building.

The principle of materials Groundtek is different.Grandtek materials squeeze moisture and fill holes and pores into which water comes from-out.For waterproofing works with grained materials, the contact with water is not important, because the project can be implemented in dry conditions.

This is an erroneous opinion.Despite the name "geopolymer resin", this is not the resin, which is used for classical resinization.The classic resin does not have such properties and the technological process passes otherwise.Do not get misleading.
