How to protect a house near a road or railroad from vibration

Admit it, none of us would like to be a tenant in a house located ten meters from the railway or a busy highway. If possible, all potential buyers of land and houses refuse such options.

And if the land near the railway tracks was offered at a very low price and it has a lot of other advantages? Or did you inherit the plot next to the highway? How, in this case, to minimize the negative impact of such a neighborhood, causing harm to the building and its inhabitants? After all, there are houses located directly at the railway stations, and people have been living there for decades.

What can vibration at home due to transport cause? Prolonged vibrations lead to disturbances in the structure of the soil, bonds between its particles break down, and the bearing capacity is lost. As a result, the foundation may shrink, cracks will appear in it and on the walls of the house. You can fight this unpleasant phenomenon, but you need to take measures to protect against vibration so that cracks do not appear again.

The best way out of the situation is to build a house at a distance of at least 40 meters from a vibration source, for example, a railway line, motorway or metro tunnel. It is this distance that the standards indicate. Therefore, on a sufficiently large plot of land located near the source of vibration, it is advisable to build a building as far as possible from the highway or railway tracks, in the far corner, in order to reduce the impact of the transport artery.

In addition, when building a house by the road, you should carefully consider not only the location of the building, but also its features..

Important! A lightweight frame house will vibrate more significantly than a brick building, which can dampen vibrations due to the high inertia associated with a solid weight..

You should immediately think about reducing vibration in a house being built on a site near highways. Experts note that in this case it is preferable to abandon the basement under the house. It is most advisable to use a slab foundation. In addition, it is highly desirable to increase the rigidity of the building, including reinforcing the walls and making monolithic belts.

One of the most effective ways that can be applied during the construction phase of the foundation is the use of rubber pads (springs), which effectively dampen vibrations. For example, tires can be used to make rubber pads that sit on a reinforced concrete base plate. The foundation is already being built over such a gasket..

There are also special plates, elastomers used for vibration isolation of the foundation, this is a more reliable option than do-it-yourself rubber gaskets.

If the building is already on the site and there is clearly a vibration in the house from nearby trucks or freight trains, you can use a simple but proven method – an anti-vibration screen..

Despite this name, this is not a screen at all in the literal sense of the word. This is a trench in the ground that will dampen vibration, preventing it from reaching a residential building. Such shielding trenches in the ground can reduce vibrations by 10-15 dB.

Rules for arranging a screening trench:

  1. It should be placed as close to home as possible. However, a minimum distance should be observed – not less than the depth of the building foundation.
  2. The length of the trench must necessarily exceed the length of the wall of the house directed towards the source of vibration. Moreover, the further from the building is the screening trench, the greater its length should be..
  3. Depth – equal to the depth of the foundation of the house to completely block underground vibrations.
  4. Trench width – about 25-60 cm.

Important! It is optimal not to fill up the screening trench at all. This way she will do her job better..

However, realizing that not all owners will want to leave just a dug trench on their site, in the end it is simply unsafe, we advise you to fill it with rubber crumbs, large gravel, expanded clay, coarse sand. These loose materials should not be tamped tightly – the presence of air is important for damping vibrations.

Another important point is that a high level of groundwater will lead to a deterioration in the effectiveness of the screening trench. Therefore, in this case, you have to take care of the availability of drainage..
