Baugut UAB, a company with years of experience, offers a modern waterproofing solution, which ensures efficient and long life of buildings: injection.

What is injection?

When looking for ways to fix and renovate damaged buildings, injection can be one of the best solutions. However, effectiveness and quality of this method requires special knowledge and awareness. As a construction term, injection means a targeted insertion, injection or embedding of liquid substance into the cavities, pores and cracks of a solid object, such as concrete, soil or other material, in order to reinforce and waterproof it. Crack filling is a complex process, which should be divided and assessed based on different phases.


The precondition for successful crack filling is the thorough examination of the structure, focusing on the causes of fracture, its effects on concrete, its type, width, length, condition, changes in width, dampness and the strength of water current. These analyses help decide which type of injection (rigid bond, waterproofing, elastic or filling) should be used and what materials should be chosen.


Main areas of injection:

  • Masonry injection against capillary rising damp (horizontal waterproofing);
  • Filling of leaky cracks;
  • Reinforcement, filling of cavities;
  • Surface coating;
  • Soil reinforcement.


Rising damp


Just like basement walls, house walls also need insulation protecting against damp rising from the foundation.

Many old houses do not have the so-called horizontal waterproofing, which has never been installed or has deteriorated. In this case, new horizontal waterproofing can be installed or the old one can be renovated. This involves creating a waterproof hydrophobic layer using pressure or gravity injection. If an appropriate solution is chosen, such waterproofing can be installed in any structure, which tends to absorb moisture.


Masonry injection against capillary rising damp (horizontal waterproofing)

There are two types of this injection method: chemical and mechanical. Mechanical injection helps fight rising damp by using a tin-plate or other waterproof material to block the way of capillary rising damp after making mechanical cuts in external or internal walls. Depending on the moisture level in the structures, chemical waterproofing can be done using two different injection methods. One of the main conditions for good horizontal waterproofing is the integrity of the structure, i.e. its solidity, achieved by the initial injection. It means that the pores and cavities of the structure are filled with a mineral substance using pressure or non-pressure injection. Of course, this is done only after determining the moisture level in the structure, number of pores and cavities, number and depth of drill holes and the distance between drills. Taking into account the type of the structure and the existing conditions, horizontal waterproofing is installed at the basement level above the soil grade or in the external part of the basement wall above rainwater or groundwater level. In addition to renewed waterproofing, it is important to make it possible for the moisture to escape from the structure and to remember that evaporating moisture contains salts, which precipitate on structures and hygroscopically absorb moisture, which may lead to surface dampness.
