“There is never enough time to do the job right, but always enough time to do it over…
Don’t be one of those people.”
Excessive friction can cause damage, which may cause seam rupture and/or separation. Poor planning, materials and workmanship will always cause havoc on your installations, not to mention driving back to the job to fix something that should have never happened.
I recommend never laying synthetic turf where seams are under heavy foot traffic areas. This would include slides, swing sets, climbing features and play equipment exits. The underpadding/shock pad is flexible. If a seam is placed in these areas, it may eventually cause seam separation. You might have to figure waste in your budget to avoid having seams in these areas.
