In the 1980s, the Novokuznetsk City Clinical Hospital began an ambitious expansion program that included the construction of several new buildings. One of these buildings was never outfitted as a hospital, and the shell stood unfinished and exposed for decades. This shell was converted into an office tower after a long repair and restoration effort.
To counter the effects of the many years of neglect, the project team began with a detailed analysis of the deterioration in the concrete matrix, in particular the below-grade basement structures. In a first step, the local Penetron team, who carried out the restoration work on-site, followed the required concrete surface preparation procedures to expose any hidden damage and micro-cracks. The surface preparation process exposed leaking cracks, damp spots, honeycombing, and structurally damaged concrete. After the major cracks and damaged areas were drilled/routed/chipped out and filled, a layer of PENETRON crystalline materials was sprayed on all concrete surfaces to ensure a durable and waterproof matrix.
