Is The Installation In The Path of Large Volumes of Stormwater?
When installing synthetic turf in commercial applications in the path of excessive water from building rooftops, sidewalks, and streets, I recommend placing commercial drains to handle rushing floodwater to prevent damage to the turf and surrounding areas.
*** Make sure your backfilling of trenches around pipes and drains is firmly compacted***
Foundation Level & Stucco Weep Screed
It is very important to keep the elevation of compacted materials below foundation weep screeds. Keeping all hardscape and landscape below the weep screed is required by most building codes and prevents water from entering the interior.
Creating a Positive Slope and Exit of Hardscape Flood Water
The images above show that the pool deck and patio deck are sloped toward the proposed turf areas. Exit Drains are installed to allow water run-off from the hardscape onto the turf and exit the yard successfully.

Drainage Pipe & Compaction
I have expressed the concern for compacting trenches when backfilling. The above pictures show poor compaction where drainage pipes were installed. This poor workmanship has now left depressions in the surface. These depressions will cause trip hazards and may cause injury. When placing drainage pipe, it is crucial that you compact the trench in lifts to prevent this from happening. I recommend a mixture of clean ¾ aggregate with the existing surface to prevent future settlement.
