Assessment of The Effectiveness of Secondary Horizontal Insulation Against Rising Damp Performed by Chemical Injection

The Influence of Injection Agents Applied for Carrying out Secondary Horizontal Damp Proof Courses on Masonry Mortar Properties

“…After a period necessary for the mortar to reach full strength, it was subjected to dampening, placing the moulds in a tray with water (on a grate) so that the samples were constantly submerged in approximately 10 mm. After two days, the moulds were taken out of the water, wrapped in foil and left for two weeks in order to ensure even distribution of moisture in the mortar (Monczynski, 2019) (Figure 1).…”

Analysis of the Impact of Omitted Accidental Actions and the Method of Land Use on the Number of Construction Disasters (a Case Study of Poland)

“…These failures or disasters are related to design or execution errors as well as improper use. Additionally, buildings deteriorate due to the use of poor-quality materials, inadequate insulation [27], or a lack of regular repairs and ongoing maintenance ( Figure 3) [28,29].…”

Which methods are suitable to assess the effectiveness of chemical injection treatments in the laboratory?

“…The ability of the invading injection fluid to displace water already present in the pores was investigated, for both water-based and solvent-based fluids, in the Seventies and Eighties [12,[15][16]. Afterwards, different aspects of this problem and, more in general, the effectiveness of damp-proofing injection products were investigated in laboratory by different researchers, who performed tests on single materials (brick, mortar) [12-13, 17-19, 20], small-size masonry blocks [15,16,18,21], or realscale walls [11,[22][23][24][25]. Some papers also reported on the drying effect of chemical injections onsite, in real buildings affected by rising damp [26][27][28][29][30].…”
