In most projects, the basement of the building walls slightly exceeds the total thickness of the supporting structures. On the formed ledges, precipitation accumulates in the form of rain and sleet, the soaked concrete foundation eventually loses its strength and begins to collapse. ebb for the basement base will help to solve the problem. It serves as a "protective shield" for the base of the house from getting wet and is made of various materials. Types of ebb tides, selection criteria, installation and do-it-yourself manufacturing - further.
For owners of private houses and for developers there is a restriction: the height of a private residential building should not exceed 2 full floors. This is the reason for the wide popularity of semi-basements: they allow you to completely legally circumvent the ban and expand the living space. Basically, the basement floor is a kind of basement. The only difference is that it has windows and partially rises above the ground level.
Structural types of basements:
The walls of the house are wider than the ground part of the base, and the basement part turns out to be, as it were, recessed externally. The advantage of the design is that practically no precipitation falls on the semi-basement walls. All the water from the roof flows down the walls without falling on the base. Such walls do not need a drain device.
In this case, the load-bearing walls of the house are in the same vertical line with the base.
In the case of a protruding type of basement, the upper edge is very vulnerable to the effects of moisture from precipitation.
Liquid accumulates at the joints of the foundation with the walls and gradually destroys the structure of the concrete. This is especially noticeable with temperature changes: in winter, the accumulated moisture freezes inside the foundation and expands, in a warm period it thaws, forming cracks in the walls. In addition to spoiled finishes, such destruction can lead to the fallout of whole bricks, leading to the formation of mold and mildew indoors. In addition, moisture gets into the basement and under the protective finish of the basement walls. All these factors reduce the service life of the structure, so there is a need for an ebb.
External ebbs to protect the basement of the walls outwardly resemble plates ... The design differs in the presence of elements that simplify installation and increase the functionality of the ebb - these are shelves and folds.The latter serve to fix the ebb to the wall, and the shelves bear the main load: they are attached at an angle to the plinth and provide moisture removal.
The width of the shelves varies from 50 to 400 mm. The color spectrum is very diverse, which makes it possible to choose a model for any exterior.
The main purpose of the ebb for the basement is to protect the basement from the destructive influence of the environment.
Based on this, their scope extends to:
Ebb tides are classified, in addition to the details of their construction, in size, color and material of manufacture.
Casting strips for basement walls protection are made of aluminum, copper, steel, PVC, stone, clinker and other materials. The varieties differ in the type of installation, have their own design features, advantages and disadvantages. Let's consider each of them in more detail.
One of the most popular materials due to its affordable price and noiselessness. A wide selection of sizes and colors allows you to choose a plastic ebb for the basement for any exterior and harmoniously fit it into the decoration of the house.
that over the years, plastic ebb tides can lose their former aesthetic appeal due to exposure to sunlight. In addition, plastic is quite fragile in the cold.
Heavy hail can damage material that cannot be repaired, but replacing a broken piece will not be difficult.
Protective structures made of sand, cement, crushed stone and plasticizer are not afraid of temperature changes and have a long service life. They are very strong, resistant to the appearance of chips, cracks and other mechanical damage, do not lend themselves to deformation. Like others, they come in a wide variety of sizes. The main advantage is that you can paint the concrete ebb in any color, matching it as harmoniously as possible to the overall finish.
The bulkiness of concrete is considered a significant defect. designs. The installation of such strips should be provided at the stage of drafting the project. And in case of failure of one of the fragments, it will not be so easy to replace it.
In addition to visual appeal, clinker tiles have other advantages:
Clinker tile is a piece material and in case of failure of one of the elements it will not be difficult to replace it.
However, such ebbs are quite expensive and afford not everyone can do them. In addition, the installation of elements requires certain skills and dexterity: it is rather difficult to fit piece elements, creating with their help an integral surface.
Most often, stone ebb for the basement is made of sandstone, less often you can find products from granite. Planks are available in black, green, blue and light with a gray tint.
The advantages of stone elements in strength, durability, aesthetic appeal and durability.
Stone ebb for the ground part of the base harmoniously fits into the exterior with brick or stone walls, plastered surface or facade panels.
Stone casting strips for the basement, due to their specific weight, are not suitable for protecting every foundation. Only a base that can withstand heavy loads can withstand such a finish. Also, the lack of natural stone in the rather high price of products, high weight and difficult installation.
Copper , steel and aluminum castings for the ground part of the base differ among themselves in appearance, weight, properties and other technical indicators. Some models are equipped with a polymer coating to prevent damage to the strips.
Coatings differ in texture and color. There are options for wood, stone and other materials. Common to ebb tides from different types of metal are only a wide range of sizes and a design consisting of two folds and a shelf.
One bend is used to fasten the plank to the wall, the second to provide a drain.
The advantages of metal shims are:
The disadvantages include the noise of such elements and the possibility of damage in the place of cuts if they are improperly processed. The most expensive are copper ebbs.
Due to its aesthetic qualities, this option is used when decorating log houses or buildings sheathed with a block house, wooden clapboard, etc.
One of the main tasks of a wooden ebb, in addition to its protective function, is not to disturb the external integrity of a building made of natural materials.
The wooden moisture-proof element for the basement perfectly complements the natural exterior of the building.
Such ebbs are made of larch, impregnated with an antiseptic and treated with a polymer. Sometimes these are just wooden planks nailed at a certain slope to allow the drainage of the waste water. With a reliable moisture-resistant backing, the material can last for about 2 decades.
Waterproof wooden strips are the most short-lived, require systematic staining and timely replacement. In the sun, the material dries up, in the rain it is saturated with moisture, and after several frosts, cracks form on the surface. The main advantage of such ebb tides is affordability, so if there is an opportunity to consider more expensive options, it is better not to stop your choice on a tree.
It is possible to replace the wooden ebb when decorating the exterior of a log house with metal or stone elements.
Metal and plastic ebb models are available in a wide range of colors, which allows them to be used in combination with other finishes of the same materials, forming a kind of set.
For example, an ebb for a plinth made of steel covered with a protective polymer layer and blue paint will look harmonious on a house where the roof is trimmed with blue corrugated board or metal tiles of the same color range. In this case, the decoration of the facade itself can be any: plaster, siding or composite panels.
Aluminum and copper tints are made in a single natural color ...
Concrete structures make it possible to adapt them to any exterior by painting. Protective elements made of natural stone have the colors of the stone from which they were made.
Based on the difference between the thickness of the basement and the load-bearing walls (or the width of the foundation overhang), the casting strips have different dimensions. The narrowest ebb is 5 cm, the widest is 40 cm. The size is selected depending on the proportional dimensions of the above parameters.
The length of the ebb tides differs depending on the material of manufacture, for example:
If you have the necessary tools, it is not difficult to install ebbs on the base yourself. The main difficulty is cutting stone when choosing structures from granite or any other stone products.
Base moldings are installed at the final stage of the facade finishing. With the help of these strips, the boundary is conditionally determined, visually separating the basement of the foundation from the outer walls.
Main selection criteria :
Ebb tides for the basement are chosen in the same color scheme with other elements of the same materials (roof, drainage system, visors, window tides, etc.) or to match the facade finish. Be sure to take into account the material with which the facade is decorated. For example, on a house made of PVC panels, an ebb for a facade made of natural stone will look ridiculous, as well as its plastic alternative on a facade made of granite chips.
Also, do not ignore its thickness, specific weight, uniformity of color, uniformity of structure, quality of the coating, if any, and the degree of difficulty during installation.
Low priced planks are generally not as durable. If you live in difficult climatic conditions, consider this fact when buying and do not give preference to cheap materials.
Correctly selected by the form factor, the ebb should ideally match the outlines of the ground part of the base:
How to determine the required size and number of planks? Measure the width of the plinth protrusion and add at least 5 cm to it - this will be the estimated width of the plank.
A difference of at least 5 cm is needed so that water flowing from the low tide does not fall on the vertical surface of the base.
The required number of planks is calculated as follows: add up the total length of the base and divide it by the length of one plank. We add 1 or 2 to the resulting value (this is a margin for overlaps, cutouts or possible damage).
Bending machine for sheet metal
If you have certain skills and want to save money on the purchase of ready-made elements, it is quite possible to make such an ebb by yourself. Basically, the elements are made of galvanized steel.
The metal is thin, easy to work with, and the coating makes the material durable (which eliminates the need for additional painting of the elements).
To make an ebb, you will need galvanized sheets, a hammer, metal scissors, a tape measure, a ruler, a pencil, a grinder, an electric drill, a screwdriver and hardware for fasteners.
Design features of products and what they are made of, provide a different installation method. Consider the options for attaching the casting strips using the example of various materials.
In order not to be distracted during the installation process by going to the building store or searching your storeroom, the first step is to prepare the tool that you will need in the process of work, as well as to purchase all the necessary materials.
To install, you need to acquire:
Based on the base surface and the stage of construction or decoration of the house, the preparatory work may be slightly different.
the aluminum rule
For example, in the case of a wet facade, we clean the surface to be covered from debris, eliminate the drawbacks by filling cracks and joints with sealant. In order for all the ebb tides to be set along a single horizon line, we make horizontal markings.To do this, we determine the highest base point, set the horizontal with a laser level and stretch the thread along the wall (or draw a line with a pencil). Using this markup, we will fix the upper limb of the low tide.
If the foundation protrusion has roughness, it will need to be leveled with a cement screed with the addition of liquid glass for additional protection from moisture.
For log walls, the preparation looks about the same, only the cracks are sealed with an antiseptic instead of mortar.
When using stone products, concrete castings or elements of clinker tiles, surface preparation consists in cleaning wall sections from dirt, eliminating defects, leveling the surface with a screed and marking.
Attention! It is necessary to install an ebb for the basement after all the work on insulation and cladding of the ground part of the base has been completed.
If the façade is designed with a recessed plinth, no additional protection is required.
The entire installation process begins with corners and protrusions. Elements for outer and inner corners may be included in the configuration. If they are not there, we cut it ourselves. It is correct to make a corner joint in the middle of the molding strip, building it up after installation in a permanent place on both sides, since it will be much more difficult to join the finished strips in the corners.
Cut out the outer corner element:
PVC moldings are joined in the corners in approximately the same way. The resulting gaps are filled with sealant.
The cutout of a metal or plastic molding for installation on an internal corner is not much different from the above technology. In this case, the upper fold remains intact, since the corner is marked in the opposite direction. When joining the sides, it is enough to cut only one.
After the corners are decorated, we fasten the strips to straight lines areas with an overlap of at least 10 cm.
Tip: to prevent the noise of rain drumming on the surface during operation, create a base of polyurethane foam for them.Metal tightly set on the foam will be virtually silent.
With a drill we make holes in the folds of the shelf at a distance of 300-500 mm. We attach the product to the supporting wall and fasten or nail the elements strictly according to the markings.
Fill the joint gap between the wall and the ebb with a sealant.
The main difficulty of this stage is the absence of an inclination of the foundation ledge. A cavity is formed between the attached strip and the rough surface, which will negatively affect the quality of fastening the elements and their further operation. This slope is adjusted even at the preparatory stage during the leveling of the basement with cement with liquid glass. Also for this purpose, a narrow board is used or the ebb is planted on polyurethane foam.
Having chosen the last option, be careful: the foam tends to expand, so do not fill the entire cavity with the material. After screwing on the ebb, place the weights on it in increments of 400-500 mm.
The brackets are attached after installing the main strips. All ebb joints are treated with a hermetic compound.
Piece products are difficult to fit to the desired size during installation, so it is most convenient to install such ebbs simultaneously with the finishing of external walls, provided that decorative bricks or others are used similar materials.
Elements are attached for an adhesive composition intended for ceramic or stone products. This glue is sold in every building store in powder form.
Important! The adhesive should be designed for work outside the building.
Also, an adhesive mixture for fixing piece elements can be prepared independently from cement and sand.
Concrete and stone are difficult to cut with improvised methods, so when installing such ebbs, try to minimize or avoid the need for adjustment.
To do this, distribute piece products evenly before installation, adjusting the width of future seams.
The installation of a concrete, stone or clinker ebb bar begins with corners of the structure. Put glue on the back of the product and press it against the base, without deviating from the horizon. When all the corners are ready, proceed to straight lines. We apply the composition and fix the elements in the same way.
When the adhesive is frozen, we seal the joints. Further finishing works are carried out after the glue has completely solidified.
Although the price is one of the main indicators, when choosing ebb tides, you should not focus only on their cost.Both expensive and cheap materials can recoup the costs - it all depends on the correct installation and operating conditions.
For those who make repairs facade of the house on their own, a few practical tips from experienced craftsmen:
Avoid knocks, scratches and other mechanical damage. In places without a protective coating, the metal will begin to rust.
To do this, you need to attach a strip with ready-made holes to the wall along the marked horizontal line and make marks. Then use these marks to drill holes for the convenience of further work.
Otherwise, you can accidentally damage the brand new ebb.
Competent choice and correct installation of ebbs for the basement basement is not as simple a matter as it seems from the outside. Coming closer to the task, you will encounter a lot of nuances and pitfalls of an individual plan. To avoid mistakes, carefully study the rules for choosing elements, features of materials and tips for their installation.
