Learn to understand the subsidence of plane structures and their restoration
GeoResin’s methods of correcting subsidence and deformation, which include lifting the concrete floor and leveling the plane of contact with the soil base, are effective for buildings of any size, including residential buildings. They also provide successful results on driveways and roads of any purpose and importance. GeoResin contractors have successfully completed thousands of projects worldwide.
What causes subsidence?
There are many different causes of subsidence and various contributing factors. They are all related to some change in the subgrade soils, which in turn causes movement of structures. For example, drought dries the ground, causing soils (especially clay) to shrink. Seismic or construction activity shakes the ground, often resulting in liquefaction, which “squeezes” fluid out of the ground. Excavation or piling activities, including the heavy movement and vibration of machinery, can shift, displace, and alter the condition of soils. In addition, different soil types are affected to varying degrees by different conditions and influences. for example; clay is particularly susceptible to compression in drought conditions, gravel and stony (rocky) soils may be more affected by nearby excavation, and excess water has a softening effect on mud. Subsidence can occur over large areas of land or in a small target area. It may occur over a long period of time, or may be an immediate reaction to nearby activity or natural events. When the ground structure has been disturbed, building settlement is common. The foundations or supports are no longer adequately supported, sinking due to the weakness of the soil.
