Calculations are based on a wall-to-wall installation and taking into consideration the interlock loss of each product, cutting and trimming of the tiles may be necessary in this case. If you are calculating for an island installation, the quantity might be more than needed.

Whether installed on an aggregate sub-base, concrete, asphalt or rooftop the Open Drainage Tile for Synthetic Turf drainage helps provide you with consistent drainage on your outdoor flooring surface. Open Drainage Tile is 1 inch high, has a 92 percent air void and a vertical and lateral drainage rate which cannot be matched by any other product in the industry.

Open Drainage Tile has been used in specs and projects where the city or county has limited the water that can be introduced into the sewer system or has limited the size or volume of the exit drains on a roof top.
If your field floats, has ponding or infill migration (which is an extreme player safety and owner liability issue) and you can't figure out why, maybe because they said it would drain XX amount per hour when in reality, it doesn't and never will.
Those issues don't get better they get worse! Countless hours in maintenance and grooming, adding materials etc. etc. what's the cost of that every month?
In a Cost Value Performance scenario, no product comes close to Open Drainage Tile.
Over the years, many architects and engineers have asked us just how fast will the Open Drainage Tile grid drain. Our reply has always been that the Open Drainage Tile is only limited by what is above it and the exit drains due to the fact that the area of an Open Drainage Tile part is 1 inch high and has a 92 percent air void.
Recently, our Open Drainage Tile grid was tested using the ASTM D 4716 Hydraulic Transmissivity Standard Test Method. The testing was done using plates on top and bottom of the Open Drainage Tile part, setting them to the required slope and adding water from one end down the slope.
Open Drainage Tile was draining so fast they had to modify their testing equipment to accommodate the volume of water Open Drainage Tile could move.
As it turns out there is practically no resistance to drainage using this tile. The most important factor to consider is the percentage of slope that the Open Drainage Tile is sitting on.
To put this in perspective of rainfall, Open Drainage Tile can handle anything that Mother Nature throws at it. On a nearly completely flat surface (1/2% of 1% slope) Open Drainage Tile will drain 2.85 inches of rainfall in one minute.
For example, it could rain over 171 inches in an hour and Open Drainage Tile could drain it. Open Drainage Tile can hold .576 gallons of water per sq ft. if needed until it can evacuate to the perimeter exit drains.
Open Drainage Tile's capability to hold water .576 gallons of water per sq ft. in the grid until the exit drains can evacuate it is another plus for the Open Drainage Tile System.
No other product on the market comes close to Open Drainage Tile's ability to drain a project, it's not even close.
This tile can also provides consistent shock attenuation properties which are a major contributor to the reduction of concussions and the safety of your players.
So when you see the claims of manufacturers rainfall per hour drainage, ask them if they have the test that really shows a products drainage capability.
When installing over rubber roofing membrane, lay down a thick geo mesh layer first.
This tile is a 100% recycled copolymer with the impact modifier, metallocene, qualifying it as a No Break plastic.
Q: I have a small rooftop area that I am trying to cover (12 x 60). I want to cover this with a small section of artificial turf and the rest in one of your other tiles. Do these drainage tiles connect to any of your other tiles?
A: These tiles do not interlock or connect to other types of perforated tiles. You could use the StayLock Perforated Tile under the turf and also as a stand-alone finished surface.
Q: I have IPE wood deck tiles I would like to place on my deck. I need to get some clearance for drainage. Could I put my deck tiles on top of these? Are they flat, and would they puncture the TPO membrane?
A: The open drainage tile may not work with the IPE deck tiles. I suggest working with a rep for a safer solution. If you use the drainage tiles over a rubber roofing membrane, lay down a thick geomesh layer first.
Q: I have a 10x12 deck that I would like to cover with synthetic turf. Would a layer of these tiles between the deck and the turf help prevent water condensation under the turf? The deck is covered with a torch roll membrane. The company that installed it says it is walkable because it is double the thickness they use for roofing, but they say I should be careful with the furniture as it could puncture the membrane. Would these tiles puncture the membrane?
A: These drainage tiles are there to help protect the membrane.
Q: Are the tiles 24''x24''? Can the tiles be cut to fit smaller/different dimensions than the tiles come in? If yes, what do you recommend using to cut the tiles? How does the turf ''attach'' to the tiles, or can it just lay on them? I am looking to buy tiles and then find a suitable turf to place on top that will look nice but not be super high/tall. I have decking that will sit next to the mat + turf combo.
A: These tiles are 2.65 feet by 2.66 feet. Please call to speak with one of our sales reps regarding your installation and turf selection questions.
Q: Does this work with all outdoor turfs? If not, which turf do you recommend for rooftops or balconies?
A: La Jolla works great on rooftop applications. As far as going over the drainage tiles, you loose-lay the turf over the tiles and secure it around the edges.
Q: Does this product have adjustable feet for leveling?
A: It does not.
Q: Can these tiles endure the cold and freeze/thaw of a Wisconsin winter?
A: Yes, these tiles can endure extreme temperatures like that.

When I first saw how small the packages were, I was a little worried. But then I saw how efficiently they stacked, and I was very impressed.
They are pretty sturdy, can actually bear weight which is what I cared about. The plastic used I wish was a bit thicker, but that would add to the overall cost. I love how they interlock with each other.
