Roof drainage
for demanding construction projects

The system exclusively uses the data you provide and bases its recommendations on design principles in accordance with DIN 1986. Subsequently, when dimensioning the downpipe size(s) and the number of drainage runs, a minimum rainfall intensity of 300 l/(s x ha) is assumed. If higher rainfall intensities are typically experienced regionally, these must be taken into account accordingly. Your information regarding the respective construction project will not be separately verified by us. Liability for incorrect information, natural wear and tear, excessive stress, or improper installation is not assumed. Adjustments to the structural conditions are the responsibility of the installing specialist company. WUS requires adherence to valid regulations and the application of technical standards when processing its products.

This tool is for guidance only. Drainage systems should be dimensioned by a specialist engineering firm.
