Prolisur uses different methods for the rehabilitation of canals and sewers, effectively restoring the watertightness of structural elements in the long term. In this way, the useful life of these infrastructures can be significantly extended through the use of modern systems with high chemical resistance.
Sewer rehabilitation is often implemented in municipal drainage systems. Often these drainage systems are historic structures exposed to increasing stress due to increasing urban development. This causes pore and surface water to gradually leak out of the grain structure of the foundation soil, leading to subsidence. The subsidence causes the rearrangement of vaults of stone walls, giving rise to cavities and leaks in the structure. In such cases, a primary goal of channel and sewer rehabilitation is to fill cavities and repair leaks.
