Longevity enhancement of wooden civil structures

A method of longevity enhancement of wooden civil structures by absorption-chemical modification of timber surfaces is described herein. The modifiers were phosphoric acid ethers. The properties of the superficial layer were studied by IR-spectroscopy and elementary analysis by Energy Dispersion X-Ray Spectroscopy (EDX) for build-up detection of covalent bonds of the modifier with the timber surface. During mycological studies, quantities of vital spores on surfaces of wooden structures were measured. As a result, the modified surface of the timber features durable a high degree of biological and fire protection enhancing the longevity of timber structures. The obtained results were practically introduced for longevity enhancement of the timber structures in Ryazan Kremlin, Anglican Church in Archangel’sk City, Nikol’skaya Church (Lyavlya Village, Archangel’sk Region), in Yaroslavl’ Wooden Architecture Museum, Holy Trinity Sergius’ Lavra, in construction of individual housings in Moscow Region
