RPP 200 and 300 rubberOroid is popular with the arrangement of roofing coatings with a multilayer structure. His difference from RRK roll material is quite significant, as evidenced by the decoding of the abbreviation. When choosing a suitable option, the labeling features, technical characteristics, rubberoid roll weight and its sizes should be studied in detail.
RPP referenced RPP with a value of 150, 200 or 300 in marking is a roll material manufactured by GOST 10923-93. It establishes the size and weight of the roll, determines which characteristics it possesses. All rubberoids manufactured in Russia are marked in a certain way. It is on this basis that you can understand which appointment will be covered.
Abbreviation RPP means that this material:
- refers to rubberoids (literal r);
- lining type (P);
- It has dust-free sprinkle (n).
Figures after letters indicate what kind of density has a cardboard base. Than it is higher, the stronger the finished product will be. Ruberoid RPP The cardboard density range varies from 150 to 300 g / m2. In some cases, additional listers are used in labeling – a or b, indicating the time of impregnation, as well as its intensity.
The main purpose of the RPP rubberoid – the formation of a lining for soft roofing coatings of the Ondulin type or its analogues. In addition, this type of materials are used for 100% waterproofing foundations, bases. The main characteristics of the material look like this:
- width – 1000, 1025 or 1055 mm;
- Roll area – 20 m2 (with a permissible deviation of 0.5 m2);
- discontinuous force when exposed to stretching – from 216 kgf;
- Mass – 800 g / m2;
- water absorption – up to 2% by weight per day.
For rubberoid RPP, as well as for other species, be sure to preserve flexibility throughout its storage and operation period. The material is covered with dusty sprinkle from glass adhesive and chalk so that its layers do not stick. Its obligatory properties include heat resistance.
Transportation of rolls is allowed only in a vertical position, in 1 or 2 rows, storage is possible in containers and pallets.
What is different from RKK?
RPP RPP and RKK though relate to one type of material, still have significant differences. The first option is intended to create a lining layer in multicomponent roofs. It does not have a high mechanical strength, has a dusty sprinkle.
RKK – Ruberoid for the formation of upper roofing. It is distinguished by the presence of coarse-grained stone sprinkle on the front side. Such protection ensures an increase in the functionality of the coating.
Stone crumb protects well bituminous layer from mechanical damage, exposure to direct sunlight.
Many companies are engaged in the release of rubberoid brand of RPP in Russia. The leaders can accurately include Tekhnonikol – a company, without one of the leading places in the market. The company produces products in rolls with RPP-300 labeling (O), intended for waterproofing basements and basements. The material is characterized by increased strength, affordable cost, withstands heating to +80 degrees.
As well as the release of RPP RPP enterprise is engaged in the enterprise CRZ. Ryazan plant produces lining materials in the average price category. The company specializes in the RPP-300 brand, suitable for the formation of the basis for a concrete tie, warm floors. Material from CRZ flexible, convenient to stripping and mounting, has sufficient strength.
Special attention deserves RPP rubberoids, produced by Omskkrovlya, DRZ, Yugstroykrovlya. They can also be found on sale in building materials stores.
Installation of coercions from RPP type referenced implies following a certain procedure. Material in rolls is delivered to the place of work in the required quantity. The number of rubberoid is pre-carried out, sufficient to fully coat all the surfaces of the roofing cake.
Of great importance is the choice of suitable weather conditions. You can work exclusively in dry weather, it is desirable to choose a cloudless sunny day. Consider the order of work when laying a subflore layer.
- Surface clearance. The roof section is released from dirt and dust, the rafters are prepared, allowing you to rise to the desired height.
- Application of mastic. It will increase the clutch with the surface, will provide the best adjacent material.
- Next begin to roll Ruberoid. Its styling is carried out from the skate or central part of the future coating, side without putting up to the layer of mastic. At the same time, warming up, allowing you to apply the material to the surface. Work continues until the whole roof is covered. In places of joints of rolls, the edges are superimposed.
When waterproofing the foundation or base, the fixation of sheets can be carried out in a vertical or horizontal plane. Each method has its own characteristics. With a horizontal mount, the RPP runned on the mastic on a bitumen basis, with a reserve of 15-20 cm. Upon completion of construction work, you need to fix the remaining edges of the material, adjust them upstairs, fix on concrete. This method is usually used at the construction stage, it allows to ensure the protection of the foundation.
Vertical waterproofing using rubberoid RPP is made to protect the side surfaces of concrete structures from moisture exposure. As a peculiar adhesive composition, a bitumen liquid mastic applied here on top of a special primer to increase adhesion. Installation is carried out by penetration, bottom up, with overlapping adjacent sections by 10 cm.
If the groundwater level is high enough, insulation is imposed in several layers.
