Horizontal insulation – methods

Horizontal insulations – methods

In our everyday operations, we use thoroughly worked out methods, owing to which horizontal insulation serves as efficient protection for all kinds of buildings.

The strategies we rely on are our own solutions – developed on the basis of long-standing experience and an accurate analysis of the most popular and commonly applied methods in the construction industry. The greatest and unrivalled advantage of our method of installing horizontal insulation is its 100% effectiveness immediately after execution. The effect is the same as in the case of protective layers installed in newly constructed buildings (during the first stages of an investment).

Being completely certain that proper installation of horizontal insulation guarantees its effectiveness and durability, we provide 30-year warranty for our services. What is equally important, the method proposed by us may be used both in case of utility as well as historic buildings. Even if the line of welds is irregular, performing horizontal insulation is still possible.

Loading of normal and load-bearing walls is also of significance – providing protection against moisture based on the PRINZ method is possible even in case of heavy loads. By entrusting us with this task, you can be sure that we will make every effort possible to ensure the perfect technical condition of your building and that we will perform the work as fast as possible. We have at our disposal state-of-the-art equipment, which is why – irrespective of the type of material walls are made of – we are able to prepare an appropriate gap.

Please take a closer look at the table below where the most popular methods are compared. Based on that you will find out that horizontal insulation made with the PRINZ method provides most benefits.

Comparison of basic methods of installing new horizontal insulation in existing buildings.

 PRINZ draining of walls through sawing processChemical methods – injectionMethod of driving stainless chrome-nickel steel sheets
  • 100% efficiency – comparable insulation as in a new building
  • durability of PEHD horizontal insulation – until the end of a building’s technical durability
  • insulation execution possible in case of all wall loads
  • extensive experience in method application (for about 100 years)
  • short time of order completion
  • relatively low interference in the static stability of the construction as compared to mechanical methods
  • insulation execution possible in case of all wall loads
  • high efficiency
  • insulation execution possible in case of all wall loads
  • experience in method application (for about 20 years)
  • high durability of horizontal insulation estimated to total at least 50 years


  • linked with more extensive repair work – more working space required
  • substantial price increase in the case of an irregular course of working joints in walls made from harder materials
  • no possibility of optical control of the behaviour of substance once it is introduced
  • high variety of available agents for injections, characterised by different levels of efficiency
  • efficiency of the method depends on many factors
  • considerable financial outlays, mainly due to high prices of metal sheets
  • in case of long walls without staying, the application of the method is risky
  • existence of a continuous joint is required
  • considerable vibrations connected with driving metal sheets, which may cause the formation of cracks
  • no possibility of execution if stones are present in a joint

Time of execution

(house 10×10 m, walls 40 cm + partition walls, approx. 22m2 wall surface in total)

approx. 3-4 working daysapprox. 2-3 working daysapprox. 3-4 working days
  • in case of brick walls, carbide tipped chains are used
  • in case of stones and concrete, saws with a diamond rope are used
  • dampness level is of no significance
  • historic buildings, palaces, castles
  • many injection techniques used depending on the type of moisture, degree of dampness or injection agents applied
  • historic buildings, palaces, castles
  • buildings with brick walls, with continuous and equal joint
  • homogeneous brick walls
  • historic buildings – walls of maximum thickness of about 1 m

Why choose PRINZ wall drainage technology?


We provide 30-year warranty for our services.


Our method guarantees 100% cut-off of capillary moisture – the problem does not return until the end of technical life of the building.


The method can be used in most of the buildings, regardless of wall moisture level and thickness.
