Methods for replacing the foundations of wooden houses.Pros and cons

The replacement of the foundation is a complex procedure that becomes necessary in some cases.The foundation is the most important part in the design of any home.If there are problems with this part, this entails problems in retired details of the structure: in walls, window shoals, ceiling.If the base collapsed quite strongly, then the replacement of the foundation becomes the only optimal solution to the problem.This will significantly strengthen the design of the house without the need for a complete demolition of the structure.

Replacing the foundation of the house is a fairly responsible and laborious process.There are several basic types of replacement of an old foundation:


  • Косметический - это замена фундамента стоимость которой наиболее низкая. Он заключается в замене отдельных поврежденных участков, ремонта трещин или прогнивших балок. К недостаткам данного способа относится нарушение целостности здания.

  • Метод с разборкой стен, являющийся, пожалуй, наиболее оптимальным методом. В этом случае замена фундамента под домом производится вместе со стенами, после их сноса и замены нижнего венца. К недостаткам метода относится его высокая трудоёмкость и длительность работ.

  • Демонтаж фундамента. Заключается метод в снятии верхнего слоя грунта, с последующей заменой венцов и восстановлением фундамента. Чаще всего такой способ применяется, когда необходима замена ленточного фундамента.

  • Метод с использованием домкратов. Это самый надежный метод, значительно облегчающий и ускоряющий процесс, но его цена порой очень высока.

Replacing the foundation of a wooden house must be carefully prepared.It is important to decide which type of foundation will be erected as a replacement.The most often recommended the following types:


  • Столбчатый. Довольно простой, но вместе с тем, надежный тип основания. Представляет собой систему столбов, расположенных в углах, местах пресечения стен и тяжелых несущих перегородок;

  • Свайно-винтовой фундамент. В данном случае происходит замена фундамента на сваи. Метод имеет целый ряд преимуществ, например, он отлично переносит морозы и перепады температур без пучения. Также отлично подходит для сложных рельефных местностей. В целом это достаточно экономичный фундамент, но потребуется применение спецтехники.

  • Ленточный. Представляет собой замкнутый контур из мощных деревянных балок. При применении такого типа фундамента возможно существенная экономия строительных материалов, и проведение меньшего количества работ с грунтом.

  • Буронабивной. Основан на специальных буронабивных сваях, которые расположены по периметру фундамента. Они могут быть как отдельно стоящими, так и связаны между собой ростверком для равномерного распределения давления.

Disassemble and replace the foundation yourself is a difficult task, and therefore it is better to trust this business to specialists.It should be remembered that not every foundation requires replacement.Some foundations may seem to be quite old, but to fully perform their support function without any complaints or with a small overcast.In this case, the best solution will be the use of Граундтек technology, which will solve a lot of problems with the foundation, namely: to perform stabilization, rise, amplification or alignment.

Technology Advantages Граундтек:


  • Работы могут быть произведены при любых погодных условиях.

  • Любая проблема с фундаментом решается без проведения земельных работ.

  • Восстановление фундамента при помощи технологии Граундтек можно производить без остановки эксплуатации здания.

  • Геополимерные смолы Граундтек полностью безопасны: для человека и окружающей среды.

  • Точность работ составляет 0,5 мм.

  • Работы производятся в кратчайшие сроки, составляющие от 1 до 3 дней.

Good day!
An old house, age of more than 70 years.
From the bottom of the house, there is a protrusion, there are cracks on this protrusion and pieces fall off.
Another inside one of the corners of the building is chips from the rest of the house!
How to restore the foundation?

Before choosing a solution, it is necessary to inspect the building for evaluating its condition and readiness to perceive the impact of repair and remediation technologies.Step number 1 is a survey of the foundation and structures.

There is no such method as "cosmetic" in principle, this is called "repairs in the invaders" and it is the most risky, so it is not clear how the voltages in the supporting structures are distributed and where to choose this very invapination.

You are definitely right that working with an existing design under load need to be correct to perceive the risks and carefully calculate and develop a project.Special attention should be paid to the designs that have lived more than half of their project life.

With this approach, the most significant is the question of the transfer of the load on the installed piles.This question is not solved without the organization of new construction, that is, it is how to start a construction site.

Of course, it significantly reduces the risks of the appearance of unpleasant signs of destruction.Even the listed is worth adding the correct operation and supervision of the building after its construction.Unfortunately, the force majeure nobody can cancel.

It is necessary to conduct a survey.According to the collected data, carry out calculations and determine wear and bearing capacity.If everything is in acceptable limits, then the building can be operated on if not, then it is necessary to decide on the further fate of the house together with the geotechnical engineer.

It is important to understand what is "subject to replacement".If this is the official conclusion of experts, then alas, yes, it is not possible to challenge it in our country in practice.But if it is only an opinion subjective, then Groundtek proved many times that everything is solved.However, in any case, it is necessary to study the design, make a survey and then take the final solution.

In essence, it is.Grained here is an alternative in general the traditional approach initially, rightly appropriately with understanding that in static systems the best option is not to interfere with the work of the design nodes than to think how to do it safely

Other types of buildings are not "light".Because the approach is the "replacement" of the foundation will be an individual character and it is best not to dismantle the old foundation, but to strengthen it delicately

Dobrynina Anastasija· Sept. 26, 2020

This is such a question, let's say the foundation began to crumble, collapse, in general, to get out of its full-fledged performance, we press it the basis, but as for the better, the health of the foundation will change if it is not induced inside?

You're right.If the foundation body itself does not fulfill the function, then the support does not make sense.In this case, the task number 1 is to bore or strengthen the body of the foundation
