Comparison of pasting waterproofing TechnoNIKOL EPP with coating waterproofing penetrating type - Maxsil Super

To date, the most common types of waterproofing (in particular those relating to foundations) include two types:

1. Coating waterproofing which includes the following varieties:
   • Penetrating (cutoff of capillary moisture);
   • Rigid (provides internal or outer part waterproof);
   • Elastic (coating with elasticity and water resistance).
2. Built-up (pasted) waterproofing, which is a roll of fiberglass, fiberglass or polyester fiber coated with a bitumen-polymer binder.

To compare the advantages and disadvantages of these types of materials for foundation waterproofing, consider the following

• As coating waterproofing take a penetrating compound for applying a waterproof coating for concrete, brick, cement mortar and brickwork - MAXSEAL SUPER® (MAXSEAL SUPER®), companies DRIZORO S.A. You can also consider more cheap material MAXSEAL
• As built-up (pasted) waterproofing take waterproofing roll material Technoelast EPP, companies TechnoNIKOL.

MAXSEAL SUPER® (MAXIL SUPER®), DRIZORO S.A.

MAXSEAL SUPER is a mixture of cements and special additives, as well as carefully selected fillers and special organic and inorganic additives.

The surface must be prepared before application. Application of special primers is not required. The surface only needs to be clean, free of paint, loose particles, grease, traces of stripping agent, dust, gypsum plaster and others. Ideally, flushing with water under pressure with a plant of the "Karcher" type. For application MAXSEAL SUPER full curing of concrete is not required.

The material can be laid both on freshly laid and hardened concrete mix.

Preparing the mixture produced as follows:

1. In a container containing 6.5-7.5 liters of water, gradually mixing, pour MAXSEAL SUPER in proportion: 1 bag (25kg.) - for approximately 6.5-7.5 liters of water.
2. Mix with a low speed drill until a smooth, thick, creamy paste is obtained (stirring for about one minute).
3. To check the consistency, lower the brush to half the length of its bristles. If the brush does not sink and does not fall on its side, but, nevertheless, it can be special efforts move in mass, then the desired consistency is achieved.

When waterproofing, apply the mixture with a nylon bristle brush in two coats. This application allows the material to penetrate into the pore structure of concrete to a depth of 2 to 20 cm (depending on the porosity of the concrete). Apply a thick layer that forms a continuous and uniform coating, do not smear it, as is done with paint, apply only in one direction.

The second layer must be applied in the opposite direction to the first. The total consumption of material for a two-layer coating should be 2-2.5 kg.

But, because we are talking about waterproofing the foundation, we will need to first sprinkle the dry mix on the moistened preparatory screed (lean concrete) just before placing the concrete foundation slab. The expense is the same 2-2.5 kg of dry mix per 1 m2.

This approach will allow the penetrating material MAXSEAL SUPER penetrate, closing the pores of the concrete of both the screed and the foundation slab.

This will allow (over time) to create a kind of single screed-slab construction that is impervious to water.

As you can see, the device for waterproofing the foundation with material MAXSEAL SUPER, technically is not no complications.

And now, for comparison, let's consider the material Technoelast EPP, by TechnoNIKOL, used for the same task - foundation waterproofing.

Technoelast EPP is a polymer-modified, deposited roll waterproofing material.

Technoelast is obtained by double-sided application of a bitumen-polymer binder consisting of bitumen, styrene-butadiene thermoplastic elastomer on a glass or polyester base. It has a polyethylene coating on both sides, which performs a protective function and prevents the bitumen composition from sticking together during transportation. As a protective layer, fine-grained dressing and a polymer film are used.

The surface must be thoroughly cleaned and prepared before installation.

Surface preparation consists in cleaning from dirt and dust (dust removal), as well as embedding cement mortar cracks and gouges.

Also, for high-quality welding, the cleaned surface must be treated with a bituminous primer with a flow rate of from 300 to 500 g. per 1 m2.

Before installation Technoelast, it must be tried on in place and adjusted to size. The material is rolled out over the surface, all excess is removed with a knife, then gently rolled back into a roll.

When installing waterproofing material Technoelast, it is necessary to check the base for moisture. It should not exceed 4% by weight.

After preparing the surface, proceed to the deposition of the material. The laying of the material is carried out by fusing with a propane torch, after the bituminous primer has dried.

Roll, after fitting, slowly unfolding the roll, melt the bottom side, gradually rolling it out. The next roll must be laid at the joint with the next one (at least 300mm), providing a continuous waterproofing membrane.

Also, do not forget that if you choose Technoelast as a foundation waterproofing, then, before viscous reinforcement and subsequent pouring of the foundation slab, Necessarily you need to set up a protective shield. Such a measure is necessary to avoid rupture of the laid waterproofing, with various possible risks of mechanical damage.

conclusions

As can be seen from the above laying technologies MAXSEAL SUPER® And Technoelast EPP, you can definitely make a choice in favor of the first, if we set ourselves the task of waterproofing the foundation.

This conclusion is made up of several factors, namely:

• There are no special difficulties in surface preparation ( not required sealing cracks; not required primer application)
• There are no special difficulties in the technology of work (it is enough just to spill the dry mixture MAXSEAL SUPER® on a moistened preparatory screed to enhance penetration into the body of the surface);
• Not dependent on the weather MAXSEAL SUPER® can be laid in the rain, tk. it is a cement based material; Technoelast EPP however, being a welded material, it is simply afraid of precipitation);
• No dependence on surface humidity (For application MAXSEAL SUPER®, complete maturation of concrete is not required, while the deposited material cannot be placed on a wet surface);
• Cements are better "friends" with each other ( MAXSEAL SUPER® cement material with special additives, therefore stringent requirements for the foundation No);
• And, finally, the economic benefit (even if you roughly estimate the list of work performed using MAXSEAL SUPER® and with the help Technoelast EPP, it will become obvious that due to the simplicity of waterproofing with cement materials, it will come out much more profitable).

Approximate cost of labor and materials MAXSEAL SUPER® ranges from 600 r/m2.

Approximate cost of labor and materials foundation waterproofing material Technoelast EPP ranges from 800 r/m2(whole pie).

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, the 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 a readily 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 welding materials on vertical surfaces for the 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 roll material 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.

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. Apply it as various types, and for waterproofing floors, buildings, foundations, boiler houses, swimming 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 is a roofing waterproofing agent used as a top layer. It is often used with EPP technoelast, thus increasing reliability. roofing works. EKP is distinguished by high heat resistance and perfectly tolerates low temperatures (up to -30 ° 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 TCH is used as roofing material 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.

2. Small selection of colors.
3. Burner heating is longer.
4. 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:

1. 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.
2. To ensure the adhesion of technoelast, the base must be coated or diluted bituminous mastic gasoline (proportions 1:3).
3. At this step, you need to roll out and cut the panel.
4. 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.
