When constructing structures such as roofs and foundations, waterproofing material must be used . There are many coatings of this type on the market today. One of the most effective and popular is Uniflex. The waterproofing agent of this variety effectively protects the structures of buildings and at the same time is quite easy to install.
Varieties of "Uniflex"
There are several types of this waterproofing. To determine what this or that material is intended for, it is possible by marking. The first letter in it indicates the type of base material, the second - the type of sprinkle on top, the third - the type of protective coating from the bottom. This material can be made:
By the type of coating "Uniflex" can be marked K (with sprinkling) or P (with a polymer film). The first variety is mainly used as the top layer for roof sheathing. The second can be used in the lower carpet of the roof or for waterproofing the foundation. Also, a variety marked with the letter M is sometimes found. This waterproofing agent is finely sprinkled and is also most often used to protect roof moisture. Thus, there is a variety of Uniflex roofing materials on the market. "Uniflex" EPP, HPP, CCI, ECP - all these are quite popular varieties.
EPG material
This type of waterproofing "Uniflex" is currently one of the most popular. Its marking is deciphered as follows: a polyester-based waterproofing insulator (E), coated with a protective polymer film on both sides (P). In fact, the Uniflex roofing material, whose characteristics are very good, EPP brand is a modern and much more perfect analogue of the well-known roofing material. Currently, it is considered a business-class waterproofing system. EPP material can be used in the same place where ruberoid without sprinkling was previously used.
Many manufacturers make this roll coating. However, its most popular variety is the TechnoNIKOL brand waterproofing device. This company makes Uniflex carpets from the highest quality materials, with the exact observance of all the required technologies. The technonikol specialists make this waterproofing device as follows:
A special composition containing bitumen, fillers and SBS thermoplastic is applied to the polyester base.
A protective polymer film is additionally applied to the resulting waterproof material.
The advantages of a material made in this way include:
Long service life. “Uniflex EPP” house structures will be protected for at least 20-30 years in a row.
High vapor permeability.
Strength. Unlike the Uniflex EPP roofing material, it does not tear under tension, and also does not stretch.
Large range of operating temperatures.
Material properties
Next, let's see what technical specifications Uniflex EPP has. TechnoNIKOL is a very high-quality brand and can be used for waterproofing structural elements of both residential and industrial buildings of any number of storeys.
Parameter | Value |
Thickness | 2.8 mm |
Breaking strength in the transverse / longitudinal direction | Not less than 350/500 N |
Heat resistance | Not less than 95 C |
Flexibility temperature on a beam with a diameter of 25 mm | -20 C |
Weight 1 m2 | 3.85 kg |
Length and width | 10x1 m |
Thus, the technical characteristics of Uniflex EPP, as you see, are really just excellent. It is almost impossible to tear this material, and it is allowed to mount it even at low temperatures (up to -20 gr.). The Uniflex EPP is transported and stored exclusively in an upright position in one or two tiers. Since the material is combustible, it is not allowed to store it in the immediate vicinity of heating appliances and open flame sources.
Cost
So, the Uniflex EPP material has just wonderful technical specifications. "Technonikol" (the price of this waterproofing is not too high), moreover, it is considered a brand that is also quite economical. Of course, Uniflex is more expensive than an ordinary roofing material. But it is also considered much more reliable. Too much roof repair is often not necessary.
The price of the Uniflex EPP of the Technonikol brand can vary between 1300-1600 rubles per roll of 1x10 m. When installing this material, a special primer for concrete, a primer, is also mandatory. A remedy for this variety from the same manufacturer costs about 1800 p. for 20 liters.
Terms of use
These are the inherent technical characteristics of the Uniflex EPP waterproofing system. Technonikol is one of the best manufacturers of this material. The “Uniflex” EPP of this manufacturer can be used both for waterproofing structures of buildings and structures from scratch, and during repair and restoration work. When performing waterproofing on a new roof, it is used as a substrate. Any other variety of “Uniflex” is laid on top, in the marking of which there is the letter K. When carrying out restoration work without removing a strictly waterproofing coating, the material can be mounted in one layer.
The manufacturer recommends using the “Uniflex” EPG both for protecting vertical, horizontal and inclined surfaces. This material is mounted using a burner. And therefore, for waterproofing structures assembled from combustible materials, it is practically not used.
Installation steps
The procedure for coating structures of buildings and structures with the Uniflex waterproofing system from Technonikol, the technical characteristics of which were analyzed above, usually includes the following steps:
surface preparation;
fitting material;
deposition.
How to prepare the surface
Before laying the Uniflex EPP roll material, the technical characteristics of which (Technonikol - in particular) are simply excellent, the roof, foundation or walls must be thoroughly cleaned of all types of contaminants. In addition, all crumbling and lagging areas should be carefully treated, and then the surface should be leveled.
The concrete base for the material should be primed. It is recommended to use bitumen BN 90/10 diluted with gasoline in a ratio of 1x3. This will increase the adhesive properties of the surface. Preparatory work can also be carried out, as already mentioned, using the finished bitumen primer.
Material Fit
This operation must be performed. This material is cheaper than many others intended for waterproofing surfaces, but at the same time more expensive than roofing material. Adjustment will eliminate the risk of improper cutting, and, consequently, excess spending. When performing this operation, the roofing material is simply rolled out on the surface onto which it will be further fused, and cut in the right places.
Deposition "Uniflex EPP"
To install this type of waterproofing, you can use both a propane and a solar burner. During the work, the lower layer of material is gently heated. The base itself also passes through the burner. After that, the roll is carefully rolled out using long hooks. In order to make the waterproofing as tight as possible, the strip should be pressed firmly to the surface. After the roof or foundation is completely glued, it is necessary to additionally check all the seams.
Useful Tips
The roofing material "Technonikol" "Uniflex EPP" is mounted in compliance with the following recommendations.
On pitched roofs with a slope of less than 12 grams. work is done from bottom to top, on steeper ones - on the contrary, starting from the ridge.
The overlap of adjacent strips must be at least 10 cm.
The installation of the waterproofing should be done together. At the same time, one person should heat the bitumen with a burner, and the second should roll the roll and press the material.
On flat roofs 4-5 gr. EPP lining material should be laid in two layers.
How to repair the roof
The Uniflex material is very tensile. However, you can still pierce or cut it. It is advisable to inspect the roof covered with Uniflex waterproofing from time to time for damage and defects. In this case, first of all, attention should be paid to the presence of exfoliation and swelling. The departed places need to be cut crosswise, bend the “petals”, cleaned, smeared with mastic and firmly pressed back to the base. From above, the material is again treated with bitumen and a patch is applied. The latter should be more damage by 15-20 cm from all sides. Also, when examining the roof, you should carefully check all the seams. If peeling is detected, the material is coated with mastic and pressed into place.
So, now you know what technical characteristics Uniflex EPP waterproofing has. At the same time, Technonikol is its best producer. By choosing this material, you are guaranteed to get a reliable roof and for a long time forget about the need for its repair.
