Technoelast ekp laying technology. Technoelast epp - roofing waterproofing material. Material Quantity Calculation
Technoelast EPP is used to create a roofing sheet for buildings and structures, waterproofing protection of foundations, basements, as well as other structures that are subject to constant pressure and deformation. It is very durable and flexible.
Technoelast EPP: characteristics
This product is a SBS-modified multifunctional roofing product. Its application ensures the highest level of reliability. Technoelast EPP is mounted by welding. It is a lining material, therefore, the correct arrangement of a roof or waterproofing implies the obligatory application of a cover layer from above. The material is very practical in installation and operation.
Waterproofing
Technoelast EPP does not deform under loads and pressure. The material is simply stretched while maintaining the integrity of the structure. The canvas does not rot and is resistant to temperature changes. It is designed for waterproofing. the following types objects:
- pools;
- underground garages;
- boiler rooms;
- industrial and loaded roofs;
- subway vaults;
- foundations.
This material is perfectly combined with EKP technoelast (a product for creating the outer layer).
Compound
Technoelast is a bituminous material consisting of a polyester base, a binder layer based on polymers and a special protective film. This canvas can be considered duplicated. On its basis, a composition of bitumen, butadine-styrene thermoplastic elastomer and filler is applied on both sides. The latter also has double-sided protection (polymer film). The basis of the canvas is white polyester, which consists of individual fibers. Thanks to it, EPP technoelast is characterized by high strength, resistance to high humidity and, compared with fiberglass, which stretches only within 2% of its size, polyester is very plastic. Therefore, it is more suitable for operation in conditions of deformation and severe loads. Technoelast EPP is a biostable material. Top and bottom is covered plastic wrap, which protects the web from sticking during transport or storage in rolls.
Installation
Laying of EPP technoelast is carried out using a gas burner according to the deposition method. All work must be carried out in the order in which they are performed. First you need to prepare the base. It is necessary to remove all debris, close up holes and cracks with a special cement-sand-based repair compound or mastic. Then it is necessary to prime the surface with a bitumen-gasoline solution (1: 3) or a primer. It must dry completely. After that, you can start fitting. The rolls are unrolled and laid out on the base in order to estimate the required volume for laying. If necessary, you can make cuts with a knife. Then it is again rolled into rolls. For welding, technoelast and the base are evenly and simultaneously heated. The roll is gradually rolled out, and the canvas is pressed to the surface. It is overlapped (80-100 mm).
Features of waterproofing
Technoelast EPP is a very high quality and modern material. It has excellent technical characteristics and is relatively cheap. Of course, its price is slightly higher than that of conventional counterparts, however given material very economical, resulting in more profit. In addition, this waterproofing roofing sheet is much easier and more convenient to lay. And it lasts a very long time, which allows you to recoup its cost.
Technoelast EPP-Thermo
This material is supplied in rolls. It is an SBS-modified roofing and waterproofing sheet of increased reliability. The material is used to create roofing carpets, arrangements and other capital structures with high requirements for reliability. It can be used in all climatic zones. Unlike a standard type of fabric, technoelast-thermo has an increased heat resistance, which significantly increases its service life. When heated, bituminous compounds do not evaporate into the atmosphere. This material is very durable and flexible. Its use ensures the highest reliability and durability of the waterproofing roofing layer.
Technology development does not stand still. This also affected construction market. More and more advanced materials are being created that have high rates of strength, durability and reliability. One of these materials is EPP technoelast, the technical characteristics of which make it the most popular. This article describes what technoelast is, where it is used. Its modifications and composition will be considered, as well as what the letters E and P mean for the technical characteristics of EPP technoelast.
What is technoelast?
Technoelast is a rolled roofing material that is characterized by high reliability, waterproofing capabilities and high strength. Thanks to its properties, technoelast can be used in any climatic conditions. Technoelast is used to cover roofs, waterproofing foundations, swimming pools, garages and other structures.
The production technology consists in the fact that a layer of a mixture of bitumen, SBS thermoplastic (and its modifications) and filler is applied on both sides to a strong and sufficiently flexible base. SBS is an artificial rubber, and talc, dolomite and other substances can serve as fillers. The top and bottom layers are a film or a crumb. It is the film that protects the material from sticking during storage in a roll, and it is also melted during the installation of technoelast. The crumb can be both coarse-grained and fine fraction. Shale, sand, etc. are used in its quality.
Deciphering the abbreviation and the main modifications of technoelast
Technoelast is produced in several modifications, each of which has its own conditions and area of use. And the letters that are indicated in the modification are deciphered as follows:
- the first letter of the abbreviation is the material from which the base is made. It can be: polyester (ether) - E, canvas - X or fabric - T;
- the second letter of the abbreviation is the type of top cover. It can be: crumb - K, film (or fine-grained dressing) - P;
- the third letter of the abbreviation is the type of bottom cover. It also comes in two types - crumb (K) and film (P).
Depending on the combination of these layers, TechnoNIKOL offers several types of technoelast:
- Technoelast EPP is a waterproofing agent for various construction projects. It is used as a different type, and for waterproofing floors, buildings, foundations, boiler rooms, pools and other buildings. In addition to absolute water resistance, it also has high extensibility and has high heat resistance. EPP is made from which SBS thermoplastic and filler are applied. The bottom layer is a film, and the top one is a fine-grained dressing. If it is used as a waterproofing for building structures, then it is welded in two layers using a burner.
- Technoelast EKP- roofing waterproofing, which is used as the top layer. It is often used with EPP technoelast, thus increasing reliability. roofing works. EKP is characterized by high heat resistance and excellent tolerance low temperatures(up to -30 o C). As the main layer for the production of ECP is polyester (which is not subject to decay) with a layer of bitumen, thermoplastic and filler. The top is covered with a large mineral film, and the bottom layer is a protective film.
- Technoelast TKP is used as a roofing material for the top layer of the roofing sheet. It can also withstand high loads, so it is often used as a waterproofing agent for underground facilities. The rolled material has high strength, increased reliability, is resistant to steam and temperature fluctuations. TKP technoelast is based on fiberglass, which is covered with SBS-bitumen with thermoelastic on top. The top layer is a crumb, and the bottom layer is a film.
- Technoelast HPP is a waterproofing agent that is mainly used as a bottom layer for roofing, foundations, swimming pools, etc. Differs in resistance to frosts and heat resistance.
- TKP roll material consists of fiberglass coated with SBS-modified bitumen and filler, and a film. Due to the absence of polyester and chips, it has the smallest thickness - 3 mm.

- The cost is above average.
Application area
Technoelast waterproofing has become very popular with various construction work. Due to its technical characteristics, technoelast EPP is primarily used where protection against moisture penetration is needed. It is also used as a material for roofing carpet.
In case of need for repair, technoelast is applied in one layer. If you need a new coating, then you need to apply two layers. At the same time, the top layer looks quite attractive, which allows you to avoid unnecessary spending on a decorated coating.
Installation and storage
For a long service life of waterproofing, it must not only be chosen correctly, but also properly laid and fixed.
The sequence of work is as follows:
- The surface to which technoelast will be attached must be thoroughly cleaned of dust. If there are potholes and pits, then they should be cemented. Then degrease the surface of the structure.
- To ensure the adhesion of technoelast, the base must be covered or diluted with bituminous mastic with gasoline (proportions 1:3).
- At this step, you need to roll out and cut the panel.
- Warm up the bottom layer gas burner and press to the base. All subsequent sheets are welded with an overlap of 9-10 cm.
Technoelast is quite easy to store. First of all, it should be placed in a room with dry air, which is well ventilated. It is necessary to stack rolls on shelves in vertical position and in such a way that they are from heating appliances less than a meter away.
If you want to provide maximum waterproofing, then ideal solution there will be technoelast EPP. The technical characteristics of the rolled material allow it to serve reliably and for a long time.
Technoelastmost and Technoelast EPP 4.0 are made of a durable polyester base, on which a polymer-bitumen binder is applied on both sides, modified with SBS (styrene-butadiene-styrene) artificial rubber. From above, Technoelastmost material is covered with fine-grained sand, from below - with a fusible anti-adhesive film with a pattern. EPP 4.0 is covered with an easily meltable anti-adhesive film on both sides.
The modifier and base properties set the material properties such as:
- flexibility and elasticity: elongation of the material at break more than 30%, elongation at break of the binder by more than 15 times, flexibility on a bar with a radius of 10 mm ("on a finger") -25 ° C;
The heat resistance of the material is + 100 ° C, which is 20-30 ° C higher than that of bituminous materials;
- excellent adhesion: to achieve a cohesive (by material) separation, there is no need to overheat the material or base;
- light, quick styling, comfort at work.
The base must be dried, cleaned of dust and dirt, leveled. The surface must either be cleaned of cement laitance by sandblasting).
Important: Technoelastmost "B" is glued to an unprepared surface, but at the same time, separation occurs along the surface of the base.
Easy to stick to the base. The lower surface of the material is covered with a film with a special indicator pattern: when the “snowflakes have melted” under the influence of the burner flame, the material is ready for installation.
The order of deposition of material on a horizontal base:
1. 5-6 rolls are unrolled on the prepared base, while the rolls are tried on one to the other so as to ensure an overlap: 6-10 cm along the longitudinal side, at least 15 cm at the ends of the rolls.
2. The material is then rolled back into rolls.
3. The material is welded “on itself” with a gas-air burner: one worker heats the material, standing with his back to the direction of gluing, the second one unrolls the material, being on the side opposite to the overlap.
4. Heating is carried out by smooth movements of the burner so that uniform heating of the surface of the material is ensured. It is good practice to move the torch in an "L" pattern with additional heat applied to the area of the material that overlaps.
5. To ensure 100% adhesion of the material to the base and the previous roll, it is necessary to achieve a small roller of polymer-bitumen binder at the point of contact of the material with the surface. A sign of good, correct heating of the material is the presence of a roller of polymer-bitumen that has flowed out from under the edge of the material. This bead is also a guarantee of the tightness of the overlap. When insulating surfaces with a slope of more than 25%, it is necessary to roll the overlap with a roller to ensure its tightness.
6. On junctions (parapets, parts, etc.) of small height, the “heat and stick” laying method can be used: the material is heated, after which the burner is laid down and two or three workers glue the material immediately to the entire surface.
7. For fusing materials on vertical surfaces, for convenience of work, it is recommended to cut the rolls into panels 1.5-2 meters long. With a significant height of the insulated surface, the sticker of the rolled material is produced in tiers, starting from the bottom.
For fixing waterproofing layers on each tier, it is recommended to provide for the installation of wooden antiseptic rails in height every 1.5-2 m, i.e. by the height of the working grips.
8. Overburning of the material is unacceptable. Its features are:
Boiling and abundant runoff of the polymer-bitumen binder, its outflow;
Strong smoke, polymer-bitumen fire;
Liquefaction of the upper surface of the material, when it "sinks" under its own weight, leaving black spots of bitumen;
- "ripples" on the surface of the material, which is not smoothed out after cooling: in this case, there is already a partial destruction of the polyester base.
In the event of a burn, the defective insulation must be replaced.
Shoe marks that may be left on hot material (immediately after welding, hot sunny day) are not dangerous, as they usually smooth out after cooling. However, you can walk on hot insulation only in soft shoes without heels and metal objects on the sole. It is also undesirable to put on the material gas cylinders and other heavy objects. If necessary, weight-distributing stands with a support of at least 50x50 are used.
