If you’ve cleaned the surface and the smell remains, the problem is likely deep in the sub-base, where basic artificial grass odor removal techniques won’t reach. You may have a “swamp effect” where urine is trapped between the turf and the soil, which means you might need to pull back a corner of the turf to inspect the base for sludge buildup.
How do you cut artificial grass for repairs? Use a sharp blade on the underside, cutting along the stitch rows. If you find the stone base is clogged with organic fines or has failed due to compaction, you may need to excavate the affected base material and rebuild the sub-base with proper drainage aggregate.
In some cases, however, the damage runs too deep for repairs alone. Understanding the different types of artificial grass and their drainage ratings can help you decide if a complete replacement is necessary, especially for pet turf used in tight side yards where ventilation is poor. If you’re unsure whether repair or replacement is the right call, our team can assess your turf and recommend the most cost-effective solution.
