Frequently Asked Questions
Do drainage holes guarantee no pooling in heavy rain?
Drainage holes in the backing help water pass through the turf to the surface below, greatly reducing surface pooling. For very heavy or sustained rainfall you still need a permeable sub-base or proper slope to carry water away — the turf's drainage is one part of the system.
Will these turf rolls work on balconies and roofs?
Yes — the reviewed products are suitable for balconies and roof terraces because they include drainage-holed backing and are designed to be weather resistant. Confirm your roof or balcony's waterproofing and slope before installation and avoid trapping water under the turf.
How long do these artificial grasses last in wet climates?
Lifespan depends on pile density, UV stability and traffic. Many users report good appearance and function for years, but several note the pile can be thinner and durability varies. Choosing UV-proof fibers, proper sub-base drainage and avoiding excessive wear will extend life.
