When boring the ceilings (11 bores) the following was
disclosed: ceiling arches of the western and central part of the
overlapping foundation are 450 mm thick in the lock area; in the
area of church-porches, porches, and stairwells - 300 mm;
under the white-stoned floor of the north gallery there are two
layers of brickwork on the side arranged in the «goose feet»
manner, under them there are a number of brickwork layers
arranged “'flatways”, and they are wet; under the same floor of
the west gallery there is a backfill of broken brick made with the
limestone solution, significantly wet; under the floor of the
southern porch area there is a sand cushion which is 800 mm
thick, and underneath one may see horizontal brickwork layers.
Utilization of new methods of diagnosis and forecasts of
structural changes in the brickwork materials applying a
scanning microscope and other equipment allowed to determine
a mineralogical composition of the brickwork and the type of
defects related to the biochemical corrosion.
Engineering examination of the on-the-ground part of the
church with the account of the above-presented results allows us
to make a complex assessment of the condition of the building,
and prepare recommendations for any further examination of
the building.
Upon completion of the full volume of planned complex
engineering technical examinations it will be possible to prepare
recommendations aimed at the protection of the World Heritage
monument, which is The Church of Ascent in Kolomenskoye.
