Sites of great historical and cultural value are threatened by natural ageing and going to ruin just like any other structure.
Sites belonging to national and global cultural heritage must be restored or reconstructed to keep structural damage to minimum, be it then repair of walls and floor or lifting and strengthening of foundation. Damage of historical buildings can be minimised by using URETEK geopolymers technology.
Manor buildings and palaces, castles and fortresses, churches and temples, but also many other sites of historical interest age, break down and go to ruin. Condition of walls, roofs and ceilings of the building is affected by constantly alternating external factors: pressure, temperature, humidity and airborne gases.
Equally dangerous are changes in soil on which the site of historical interest has been erected. Thus, weakening of soil under the structure may cause subsidence of ground floor and reduce stability of foundation, which leads to damaging other structural elements of the structure.
Complications related to strengthening soil
Subsidence of foundation and floor of sites of historical interest often causes occurrence of cracks in floor and walls. In that case, simple cosmetic repairs of walls and floor are not enough to improve the situation, because the cause of cracking is not eliminated. Without improving the condition of substrate and lifting foundation or floor, the situation continues to worsen and may ultimately result in complete destruction of architectural monument.
Although sites of historical and cultural interest are generally renovated by using state-of-art technologies and building materials, lifting of floors and strengthening of foundation in these structures is often performed using traditional methods. However, traditional technology along with involvement of heavy machinery and concrete and earthworks may damage the site of historical or cultural interest.
