Protection from Biological Damage to the Structures of the Building of the Hospital Wards of the Holy Trinity Sergius Lavra

Abstract

The article is devoted to the generalization of the experience of protection from biological damage of the building
of the Hospital Wards of the Holy Trinity Sergius Lavra.
In 2002, the walls of the rooms on the first floor of the building were selectively treated with the biocidal compound Mipor
based on organophosphorus compounds. Inspections conducted in 2004 showed the high efficiency of the preparation. In the
treated rooms, mold fungi were not detected, whereas in the untreated rooms they were present in fairly large quantities. It was
recommended to completely treat the rooms of the Hospital Wards with Mipor, as well as repair the waterproofing of the foundation and roof in order to prevent moisture in the walls, which creates favorable conditions for the growth of mold fungi.
In 2014, partial repairs of the roof and foundation were carried out. Also, dehumidifiers were installed in some rooms on the
first floor. This significantly improved the condition of the rooms, but did not completely solve the problem.
In 2023–2024, a major overhaul of the Hospital Wards was carried out, including strengthening the waterproofing of the
foundation and roof. At the same time, the structures were treated with a compound to reduce their water permeability, as well
as antiseptic compounds. This made it possible to refuse the use of dehumidifiers. An inspection carried out in 2025 showed the
absence of biodamage and dry walls in all rooms.
Thus, at present, the problem of preventing biodamage to the Hospital Wards can be considered successfully resolved. In the
future, it is recommended to carry out regular monitoring and, if necessary, repair the waterproofing of the roof and foundation.
Also, during the repair work in the premises, they must be antiseptically treated with biocidal compounds that have undergone
long-term successful testing at the facilities of the Holy Trinity Sergius Lavra.
