Eskisehir is built on a wide, flat plain split in two by the Porsuk River. That topography makes natural discharge of surface water difficult and raises the groundwater level, particularly in areas close to the river bed. Sudden snowmelt in the continental climate of Central Anatolia is another factor that increases seasonal water pressure.
The city has a strong industrial base, led by defence and rail manufacturing, and waterproofing at ground floor level in production facilities matters for business continuity. In Eskisehir we apply solutions on both residential and industrial projects that account for the water retention of this flat plain soil.
For homes in neighbourhoods close to the Porsuk River in Eskisehir, we install drainage lines with backup pump systems against seasonal rises in the water table.
At production facilities in the industrial zone we combine ground floor waterproofing with rigid membrane systems that stand up to heavy machinery loads.
The three situations we meet most often in Eskişehir
Water table around the Porsuk. In settlements near the river and the plain the water table comes close to the surface. Drainage is an inseparable part of waterproofing for basements and below ground spaces in these areas.
Freeze thaw in a continental climate. Layers near the surface freeze and thaw repeatedly through winter. Water trapped beneath terrace and balcony finishes expands through this cycle and debonds the tiles. Surface drainage lines must sit below the frost depth.
Surface water on flat ground. Where ground fall is limited, rain and snowmelt do not drain away on their own. Without correct falls and a drainage arrangement around the building, water approaches the foundation.
What we look at during the survey
Distance to the river and the plain, water table level, the local frost depth and whether existing lines sit below it, whether a drainage arrangement exists beneath the terrace finish, and surface falls around the building and the discharge point.
