Frequently Asked Questions
How much drainage do I need for heavy rain?
Aim for turf with perforated or highly permeable backing and a sub-base that drains — crushed stone or compacted aggregate with a slight slope to a drain. The turf alone helps, but surface drainage and base prep determine whether water pools.
Can I use these turf rolls on a roof or balcony?
Yes, but use a ventilated underlay and ensure the building membrane isn’t damaged. Choose a product with perforations and confirm the rooftop drainage outlets handle the runoff; consult a roofer for waterproofing compatibility.
Will the synthetic grass fade or change color over time?
Most modern turf has UV-stabilized yarns, but customers note some batches can look slightly yellow in certain light. Premium products usually keep color longer; ordering a sample helps confirm shade before committing.
