Local rainfall
What does 622 mm mean for a house?
Water does not disappear from a property on its own. Roof water needs a stormwater system, surface water needs correctly graded ground and water in the soil needs perimeter drainage to carry it away from the foundations.
The area managed by the drainage and stormwater systems receives an average of
164,000 litres
per year. The estimate is based on an average detached house in 20810 Turku, with a building footprint of 105 m², plus the three-metre zone around the building.
Where does the water go at your home?
Ground grading directs rain and meltwater away from the building. The stormwater system carries roof water away in a controlled manner, while perimeter drains remove water accumulating beside and below the foundations. All three need a safe, working discharge route.
One less worry for your home
When water flows the right way, home can feel like home
Working perimeter drainage, a properly designed stormwater system and correct ground grading carry water away from the building. Good moisture management is almost invisible in daily life. That is exactly how it should be.

Frequently asked questions
What does a perimeter drainage renovation cost in 20810 Turku?
The price depends on the building's size, drainage length, soil, working space, surfaces to be reinstated and the water discharge route. Enter the exact address to receive a property-specific plan and price.
How does soil affect a drainage renovation?
Soil affects excavation, trench construction, water movement and the machinery that can be used. Area data provides local context, but each property is always analysed separately.
Why does rainfall management matter?
Perimeter drainage, roof water, ground grading and a safe discharge route form one moisture-management system. Replacing drainpipes alone does not address every source of water load around the foundations.
