WATERPROOFING

Protection of buildings from moisture and water, known as waterproofing, is a very important area of construction. The majority of construction complaints are related to water, which exists around us in three states of matter. Due to the various potential problems caused by water, it is crucial to perform a proper „engineering diagnosis“ of the issue (whether it involves leakage, condensation, groundwater, etc.).

After identifying the problem, it is equally important to choose the correct technical solution (the proper installation of suitable materials). Over the past twenty years, chemical construction technology has experienced rapid development, especially in terms of quick material application, with waterproofing materials holding a significant position among them.

WATERPROOFING MATERIALS

Waterproofing materials constitute a special group of construction materials subject to very strict quality requirements. These materials are not considered structural or load-bearing, but they are responsible for the usability and condition of the structure. The primary task of waterproofing materials is to protect the structure, or building, from the effects of moisture and water without degrading themselves. These factors, besides impacting the durability of the structure, also affect the living environment of people.

General physical and mechanical requirements for waterproofing materials:

  • Impermeable to water and do not absorb it

  • Durable when in contact with water and other materials

  • No harmful effects on other materials they come into contact with

  • No harmful effects on people and the environment during installation and later use of the building

  • Satisfactory plasticity at low temperatures and stability at higher temperatures

  • Good resistance to sudden temperature changes

  • Ability to accommodate the movements (expansion and contraction) of the underlying structures

  • Able to bridge small cracks in the underlying structures

  • Resistant to deformation under pressure

  • Easy to apply

  • Good electrical insulators

  • Self-extinguishing or at least flame-retardant

  • Resistant to punctures and plant roots
