Bitumen mastic waterproofing. How to choose it correctly?
Providing high-quality insulation protection of objects is the main goal of bitumen mastic waterproofing
Efficient and durable thermal, hydro and vapor insulation of industrial and commercial facilities is provided through the use of high-quality insulating compounds that create a seamless coating with excellent protective functions. The leader among materials of this kind is bitumen waterproofing mastic.
The main provisions on waterproofing with bitumen mastic
Bitumen mastic waterproofing itself is a process of treating surfaces, objects, structures and structures of various types and purposes with liquid compositions based on bitumen, bitumen-rubber, bitumen-polymer or emulsion components. Before use, some modifications of waterproofing compounds should be heated to operating temperature, while others can be operated immediately after opening the factory container, since they do not need to be fired. The first type of bitumen waterproofing is mastic for "hot" use, and the second is mastic for "cold" laying.
In what cases is bitumen mastic waterproofing carried out?
Bitumen mastic insulation is one of the most popular types of construction work, as it ensures proper mechanical and anti-corrosion protection of treated objects, increases their service life, and also does not require special installation skills and additional equipment to create an optimal level of hydro, heat or vapor insulation.
Waterproofing with bitumen mastic, the consumption of which completely depends on the area of the treated surface and its material, is used in the process:
  • providing anti-corrosion and mechanical protection of concrete, reinforced concrete, wooden and metal surfaces;
  • creation of insulating protection of monolithic insulation materials;
  • ensuring the vapor tightness of industrial and commercial facilities;
  • the construction of roofs in order to create their heat and vapor barrier, as well as the laying of roofing coverings;
  • elimination of defects in the roadway and asphalt pavement;
  • protection of pipeline bases from corrosion and mechanical damage of their insulating coating;
  • waterproofing of floor coverings.
The selection of the necessary brand of bitumen waterproofing mastic is carried out in accordance with the type of work being carried out. For example, MBK-G mastic is used for roofing waterproofing, and the composition of bitumen universal mastic is excellent for waterproofing foundations, basements or other surfaces.
The main operational advantages and disadvantages of bitumen waterproofing
The waterproofing device with bitumen mastic of various brands, compositions and types of applications allows for high-quality insulation and long-term protection of treated objects. In addition, bitumen mastics for waterproofing have:
the ability to create a high-strength seamless coating that is resistant to deformation, corrosion and negative external influences;
water resistance;
the ability to provide optimal thermal, hydro, and vapor insulation of facilities;
high adhesion to surfaces made of various materials;
wear resistance of the created coatings;
the ability to operate even in harsh climates;
monolithic;
optimal elasticity and plasticity;
high penetrating ability of "hot" bitumen mastics;
simplicity and adaptability of application, which is typical for "cold" mastic compositions for insulation work;
high level of adhesion to the bases;
the ability to dedust surfaces.
Among the disadvantages of bitumen waterproofing for road works, special attention is paid to compositions for "hot" application, since their operation is associated with a fire hazard, since before applying them to the surface, the composition is adjusted to an optimal consistency, which bitumen mastic acquires under the influence of high temperatures. These temperatures usually range from +160°C to +180°C. Therefore, work with waterproofing mastics for "hot" installation requires special attention and compliance with safety regulations.
