There is a prejudice that with proper selection, the trunks of already dead withered trees will have a number of important advantages... But the practice of using such lumber completely debunks this myth.

The term "dead wood" is applied to trees that have not yet fallen and are standing on the vine, but they are already dead. This definition may apply not only to individual trunks, but also to entire sections of the forest. Dry wood is also called lumber cut from dead round timber. The fallen forest is distinguished separately. These are dead dry trees that lie on the ground. They can fall, for example, after strong winds, snowfalls and the like.

The tree does not always die (dries up) from old age. This can happen for other reasons, namely:

Critical rise groundwater accompanied by strong waterlogging of the soil;
Critical decline in groundwater accompanied by drought;
Prolonged cold weather with abnormal frosts;
Harmful industrial impacts;
Strong soil compaction;
Forest fires;
Damage by fungi or insects;
Various mechanical damage ...

The intensity and speed of such processes depends on different factors... Sometimes destruction occurs in a matter of days (15-20 days) - at the same time, a layer of blue 1.5-2 centimeters thick appears very quickly throughout the entire wood mass.

Inspection of trunks in dry areas where trees died long ago (a year and a half ago) allows us to draw important conclusions. Only 2 percent of all the logs available can be used to produce relatively buildable lumber. 70 percent of this forest will be used only as firewood. The rest can be considered waste containing great amount pests and pathogens.

A pattern can be traced - the longer the period from the death of a tree to the moment it is harvested, the more useless and dangerous the dead wood will be. Deadwood is damaged and destroyed even faster than dead wood, since the contact area of ​​the trunk with the soil is much larger.

In some cases, there is only a few months to select an intact sawlog from dead wood.

Infection can occur in the warehouse and even already in ready-made structures, not subjected to harsh antiseptic treatment. In addition, dead wood products can act as a source of infection, being in the vicinity of normal wood.

In addition to damage by fungi and insects, dead wood and dead wood are characterized by the loss of physical and mechanical properties important for construction. Dead wood dries without control, unevenly - at the same time, rather deep cracks not only along, but also across the fibers. For a bar or edged board of GOST from a green forest, this is completely unusual.

Uneven stresses, in addition to significant cracking in different directions, can lead to deformations of products after sawing the log - warpage of various types, which are simply impossible to fix during installation, because lumber just breaks.

The presence of fungal infections and damage by harmful insects is not allowed by the standards of GOST, not only for aesthetic reasons. These pests feed on wood, after their vital activity, voids and loose areas remain in the trunk, which leads to such negative phenomena:

Lumber becomes less hard, more capricious during installation and processing;
products lose bearing capacity;
structures are more heat-conducting and sound-permeable;
loose tree in to a greater extent absorbs water.

Most unpleasant is the fact that it is very difficult for an inexperienced person to recognize dead wood against the background of lumber from a healthy forest. And not every seller honestly points out the origin of his goods, which gives him the opportunity to get extra profit (deadwood round timber and sawn timber products, for example, edged board

Dead wood is an extinct forest, a forest infected with a bark beetle, a burnt forest, a forest affected by natural disasters.

What is the difference between a board, a timber according to GOST 8486-86 from dead wood and how to distinguish a healthy fresh forest from a bad low-quality one, I will tell you in this article

V Lately in the capital markets, you can often find a board, timber at a very attractive price from 4,600 rubles / m3 to 5,000 rubles / m3. In 90% of cases, at this price, you are offered dead wood and they assure you that this is a board of the first grade, produced in accordance with GOST. Such material is not suitable for residential construction; in most cases, it is infected with the lumberjack beetle and bark beetle, which in turn contributes to a mortal danger to the tree.

Such material as dead wood can be purchased for the following purposes:

Formwork erection;

Construction of scaffolding;

Construction of temporary facilities;

Construction of a temporary fence;

For other construction purposes (Except for residential construction);

If you are offered a board, a bar at a comparatively cheap price, then think about whether it is worth spending your money on such a purchase. After all, the purchase of such material for residential construction is fraught with consequences. The price for dead wood is from 4,600 rubles / m3 to 5,000 rubles / m3. The price for normal fresh wood is from 5,700 rubles / m3 to 6,700 rubles / m3, depending on the type of GOST or TU.

When buying via the Internet, pay attention to the reputation of the store, whether everything is indicated on the site, pay attention to where the production is located. Mostly dead wood is produced in the Moscow region and nearby areas (due to a large number fires and droughts in these areas). For example, the board, the deadwood timber that we sell, is produced in the Tver region.

Always when ordering edged lumber, check with the manager whether they will bring you dead wood (or it is better to warn that if the machine is with low-quality wood, you will refuse it)

If a construction company or a private team of craftsmen is engaged in the construction of your house, you do not know well. They don't quite trust the purchase of lumber. good idea(there have been cases when builders bought obviously bad material for profit).

How to distinguish a green forest from dead wood?

Below are the pictures of the substandard edged lumber all these facts point to dead wood

Holes with a diameter of 3-4 mm are visible on the board, this indicates that the board is infected with bark beetle! Also pay attention to the fact that in places where there should be wane there is blackness (most likely the forest was damaged by fire)

There are also holes from the larvae of the bark beetle and the barbel beetle. but the color of the wood is natural (the forest suffered from drought or was damaged by pests)

This photo shows that the board has partially turned into dust, and has a characteristic reddish color or dark blue areas. (this suggests that over time all these areas will turn into dust, and it is simply dangerous to use this material for residential construction)

Another difference between dead wood and normal wood is the presence of cracks almost along the entire length of the board, and even a through crack is possible at the ends! (on the edged board cracks also come across from a normal forest, but they are mostly small and shallow)

I hope the article was informative for you and you understood the dangers of buying deadwood lumber for residential construction.

You can buy dead wood for rough work on our website at a price of 4,900 rubles / m3 in the section

What's happened deadwood? Surely, a person far from construction will immediately open an encyclopedic dictionary and read information about dry that fits in a small paragraph.

According to encyclopedic data deadwood refers to that part of trees or forests that do not show any signs of life. However, deadwood does not rot or fall, but continues to cling to the roots of the tree. If you go into any forest, you can see deadwood in the form of freestanding dried trees, or whole forest areas dead wood who died from drought or a sharp drop in the level of groundwater, frost, sunburn, forest fires and a whole series. If we talk about separately standing trees – dead wood, then in this case the tree could die due to "old age", attack of harmful insects or fungal diseases. As practice shows, conifers are more often exposed to dead wood rather than deciduous.

Cabin dead wood Is a very important activity that contributes to the prevention of forest fires. After all, everyone knows how well it burns dry wood especially when it is under scorching sun... Some 5-10 years ago in the Russian construction market and did not hear about the construction of houses from dead wood... However, fashionable Western trends are very quickly being introduced into our market, because many construction companies Russia today appreciated all the advantages of working with deadwood and offer a wide range of building structures based on dry wood. The most interesting thing is that they were the first to decide to use deadwood in the construction of houses, practical Americans who opened Europe houses from dead wood.

Interestingly, succumbing to this fashion trend, Russian construction companies thought they had discovered something new for themselves. However, digging into the history of construction, we found that the first houses from dead wood appeared many centuries ago and not just anywhere, but in Russia! After all, even our great-grandfathers noticed that the most durable and strong houses are made from dry wood, so they specially chopped up the bark so that the tree dries up faster. Moreover, the construction of houses from dead wood- it is also a colossal saving of sharply decreasing forest resources. Agree, why ruin living tree, if every year in our forests appears a huge amount dead wood... Therefore, at home from dead wood today are our main solution to the problem of lack of housing and the preservation of selected woodlands.

The main advantage of a house from dead wood is that it solves the main problem of construction wooden houses – natural shrinkage at home, which occurs as the "living" tree dries up. As you know, experienced specialists do not recommend immediately after building a house from a log house to carry out Finishing work, since at first it will shrink by about 10-15 cm. But the construction of a house from dead wood devoid of this disadvantage, because in the already "dead" tree there is no moisture, which "shrinks" the walls of a log house. Therefore, in this case, at home from dead wood can be finished immediately after the completion of its construction.

Ideal for ordering dead wood is the northern forest, which has the greatest strength and durability. Certainly, dead wood cost from northern conifers you cannot call it low, but by ordering such a tree, you can be sure that you will receive a high quality home.

When life cycle dry wood finally comes to an end, root system slowly begins to die off and the plant itself becomes dangerous, since a small squally wind or hurricane can easily knock down or even uproot dead wood. The drying process that has begun with the help of external natural conditions gives the wood good resistance to mechanical damage, the influence of various biological factors and exceptional hardness... It is thanks to these characteristics that dead wood (pine, spruce, etc.) is so highly valued in the industry.

To guarantee the quality of wood, specialists can monitor dead wood from the beginning of its formation to removal from the forest. After the object passes the control and is recognized as a quality specimen, the process of extracting the trunk from the ground along with the root system takes place in order to minimize damage to the most valuable part of the trunk - the base, as well as to a number of growing plants. The uprooted trunks are removed from the site with special care. There are known cases of involving a helicopter for the correct and careful extraction of the barrel, although this is done mainly in hard-to-reach places, in mountainous or swampy areas, where it is difficult to get to other equipment. Before carrying out any work on the extraction of a tree, it is imperative to obtain permit for cutting dead wood in the forest.

If in the future a dry tree is used to build a house, then the best specimens will be plants that have reached the age of 100-200 years. There are very few such specimens and they usually grow in northern latitudes, which significantly increases the price of housing made of such material, but a house built from dead wood is striking in its beauty, quality and durability, it does not shrink and, strangely enough, it is less susceptible to fires than a log house from ordinary wood. Therefore, the sale of dead wood is quite a profitable event.

Clearing the forest from dead wood

For dry and diseased trees in the forest, it is necessary to constantly monitor, as well as record the slightest changes. This is done so that there is an opportunity to intervene in time and turn the dangerous situation in a different direction. There is no need to immediately resort to drastic measures, sometimes timely pruning of affected or dried branches may be sufficient. Wood affected by pests, rot or other diseases poses a dangerous threat to other plants in the forest. You need her not only remove it in time, but also dispose of it soon so as not to harm the rest of the green spaces and cause a full-scale epidemic.

Cut off dead wood in whole or in part is sometimes very important. Such a useless, and in some places dangerous, tree only blocks the light of other healthy plants, and if it falls on its own, it can cause mechanical damage to other green plantings. Who knows, maybe they themselves can turn into dead wood from such an injury. In time take out the felling dry residues wood is an equally important event. This is not only the cleaning of the area for the full growth of other representatives of the forest, but also the prevention of fire hazardous situations.

Measures aimed at preventing dangerous situations and preventing epidemics are called sanitary or recreational and should be carried out only by competent specialists who decide whether it is necessary to cut dead wood and cut down a diseased plant or not.

Cutting down unnecessary, dry and or diseased plants can be done in 2 ways:

• 1st method. Clear sanitary cabin. It is carried out when dry trees prevail in the selected area of ​​the forest. Such felling takes place when the affected plants account for 40% or more of the stand of one location. These zones are subject to the earliest complete renewal of green spaces.
• 2nd way. Selective sanitary felling. It is carried out to partially localize certain objects among other trees in the forest. This work is considered more painstaking and sometimes it can take much more time and effort to neutralize one dry tree than with clear sanitary felling, when plants are chopped down. The complexity of the work lies not so much in the neat sawing of a dry branch or the whole tree, but in ensuring the safety of the rest of the green spaces.

In any case, before starting any work, i.e. immediately before deciding on removal, the plant should be examined by a specialist who assesses the degree of risk to other trees. Experts will offer the most suitable way felling based on the current situation and the terrain. After that, a felling ticket for dead wood must be issued, and only then a team of contractors is selected who will carry out this work.

Accurate and qualified extraction of dry stands will allow clearing the forest, which will create a favorable opportunity for planting young stock, renewing the green fund.

Deadwood cleaning in the city

Cutting dry trees within the city Is a difficult and dangerous event. It can be carried out quickly and without loss of quality only by experienced climbers and employees of companies for the removal of green spaces. In parks, recreation areas, botanical gardens, squares, not only sanitary cabin dry and damaged plants, but also pruning when only the crown or dead branch is removed, and the rest remains intact. Such an event is intended to preserve the aesthetic appearance of the recreation areas of the townspeople. In addition, the complete removal of the entire tree as a whole is a more costly process, both in time and in terms of money. In most cases, it is enough to carry out a simple cut or crown a part of the plant in order to solve the problem. In addition, cutting or felling an entire object will require further uprooting the stump in order to get rid of the tree completely.

Many people think that there is nothing dangerous in removing dead wood, but buying a chainsaw is not enough for this. Any work on dry trees, wherever they are carried out, must be carried out in accordance with the current regulation and legislative regulations... Each organization or company that will carry out the process of felling or sawing must have all permits, and workers - a certificate for the performance of the relevant work.

The elimination of dead wood can occur as wholly and in parts... If the space under the tree allows, then you can choose a simple method of felling the whole tree, towards the natural inclination of the trunk or in the opposite direction, using a guy.

Most often, deadwood felling in urban conditions takes place in parts... An unreliable trunk gives very few chances for a climber or arborist to climb on it, so there is a need for special equipment: aerial platform and truck crane... In this case, the carrying capacity of the machine must be at least 200 kg. If there is no free area under the tree for dumping the sawn fragments, then the method of hanging the sawn fragments on neighboring trees or using a truck crane is used. It will take a lot of time to remove such dead wood, while the price will be much higher than for a conventional saw cut of a plant as a whole.

Uprooting dry trees can be done in only two stages: in the first, the trunk itself is cut, in the second, the remaining stump is removed along with the roots.

Deadwood video

It looks like we are being fooled and very cool!

Yes, deadwood wooden houses have advantages - no shrinkage, insignificant shrinkage, specific color and texture, plus ingenious marketing. Who doesn't know about Kelo houses today?

Well, now about the cons. And there are disadvantages, and what are they!

All dead wood, somewhere more, somewhere less affected different kinds woodworms and in an amicable way it must be destroyed, since it is a source of infection (read sanitary regulations through the forest).

Inside such a tree there is a gnawed system of tunnels, dust, waste of the larvae, live larvae, pupae and the insects themselves (beetles). There can be so many life cycles of all this population living in dry conditions, which is quite enough for the complete transformation of the log into dust.

In our life, we have never seen trees standing on the root affected by woodworms anywhere and never - neither in Karelia, nor in the Arkhangelsk, nor in the Vologda regions, nor in Komi, nor in Siberia.

The deadwood procurers themselves in Karelia confirm that there are no unaffected trees. All the deadwood houses that we have seen and all the logs that are shown at the regular exhibitions dedicated to wooden houses, also pierced by insects (right at the exhibition in Sokolniki several years ago we saw a woodworm beetle crawling out of such a log!)

When you imagine what can be in this log, it becomes somehow uncomfortable.
And here for the owners of a fashionable house made of dead wood there are two options: either let everything go as it goes, and we live together with the possible “population” of the log, or we need to poison this living creature with chemicals. Then about the benefits of dead wood, as ecologically pure material have to forget.

The lover of the exotic in the form of a deadwood house, who caught the trend and settled in the Kelo house, can live wherever he sees fit. But! How will woodworms affect the trees and forest growing next to such a house, flying out of a log of a fashionable house? The answer is obvious: they will continue their genus, which means they will infect nearby trees. And very soon there will be another dead forest near the dead wood house.

And one more thing: our ancestors never did anything, let alone housing! They were not built from dead wood.

All of Russia was made of wood, and at least somewhere in the memory of generations it would certainly remain. And now, when you ask about the dryness of the old people wielding an ax from Arkhangelsk to Krasnoyarsk, they just open their eyes wide and shrug their shoulders: "utter stupidity - how is this dead tree home?"

Probably because our ancestors understood and felt nature better than us, building houses for life from a dead or sick tree was considered absurd.

And Deadwood is just a tree that is dead - either from age or from illness.

How does a living tree affect a person? - beneficial. And no one denies this.

How does it affect human dead tree? And a dead house?

Let someone try to refute it and say it's good.
