AquaDrain® T25

Capillary passive surface drainage for coverings on gravel / chippings

Information

On (roof) terraces, you are often confronted with the situation that there is little or no fall on the waterproofing. The water collects over a large area on the waterproofing and drainage is very slow. AquaDrain® T25 has a thickness of 25 mm. This prevents hydrostatic pressure and therefore damage to the waterproofing. The laminated special fleece raises the entire area of the covering and prevents trapped moisture from getting back into the structure.

Advantages

Specially developed for use on (roof) terraces without a fall.
25 mm thick – prevents large puddles forming on the waterproofing.
Prevents hydrostatic pressure from standing water on the waterproofing.
No fouling on the waterproofing thanks to the special filter fleece.
Footfall noise improvement of up to + 33 dB.
