Description
Drainage channel market Germany: sales in thousand linear metres and forecast to 2031
How is the drainage channel market in Germany developing? The dataset provides demand for drainage channels for linear drainage at buildings in thousand linear metres for every quarter from Q1/2021 to Q4/2031 – as historical market data and forecast.
The dataset covers channels with gratings that collect surface water from paved areas along a line: at garages, entrances, yards, parking areas, terraces, level thresholds and commercial yards. Channel bodies are mainly polymer concrete and concrete, plus stainless steel and plastic; load classes to DIN EN 1433 range from A 15 (pedestrians, private driveways) to D 400 and above. Public roads and squares, yard gullies and indoor floor drains or shower channels are excluded.
In new build almost every driveway and garage forecourt receives linear drainage, as falls towards the house and level thresholds require it. When paved areas are renewed, the existing, very durable drainage is often kept. As channels and paving are laid together, demand tracks paved areas closely: the garden boom up to 2022 was followed by a sharp slump in 2023; after a further decline to 2026, sales recover with new build and modernisation. Infiltration requirements and the sponge city concept could add support but are not included.
Which questions about the drainage channel market does the dataset answer?
- How many linear metres of channel are laid each quarter, split by residential and non-residential buildings?
- What share does renovation hold compared with new build?
- When do channel sales bottom out, and how do they recover to 2031?
- How pronounced is seasonality across quarters?
Who is the dataset for?
Channel system manufacturers use the series to plan sales and ranges, foundries and grating suppliers to plan production. Merchants, landscapers, paving contractors, external works designers and analysts use it for planning and sales.
Data basis and methodology
The dataset contains the total market and its split by new build/renovation and residential/non-residential buildings. The model links completions, permits and renovation activity with paved area per square metre of floor area, channel length per square metre of drained area and the share of areas with linear drainage. Volumes were derived from stock, equipment and renewal parameters and checked for plausibility against available industry information and internal data.
Delivered as CSV and Excel files, each in German and English, with 44 quarterly values. Related datasets: Concrete paving stone, Terrace slab (concrete/natural stone), Prefabricated garage (concrete) and all data on structural work, load-bearing structure and outdoor facilities.
