The paper describes strengthening historical buildings made of limestones rocks located in the Republic of Crimea. The stones were treated with the chemical compound Oxal NK100 for filling a porous material reducing water absorption and strengthening the treated stones. The stones with additives was tested and the results were compared to natural limestones (reference samples) which not treated with any chemicals compounds. All samples are extracted in-site from an actual historical construction located in the mentioned Republic. The effect of the chemical composition Oxal NK100 on the water absorption of the investigated stones is illustrated and incorporated. The comparison data of the index graphs before and after the addition of the chemical composition are given and described.
