Putting the grass carpet down

It is actually more complicated than I made it sound below. They cut it really carefully, like when they cut carpet for installation in a home. And judging by the job the guy did when we redid the carpet on our stairs, the Polygrass guys are actually more meticulous. Then they put 8 inch nails in about every 1-2 feet. the seams run every 15 feet and are cut in a wavy pattern. under the seams, they put this hard white liner down, and coat it with gasket adhesive, then stick the grass on top. Finally, nail it down.

 

  

  

Once the grass is all stapled and glued down, they fluff it and start infilling it. First they rub in 1/4 to 1/2 inch of sand. On top of that, goes same amount of black rubber grit. This adds a lot to the spongy-ness and realistic feel to the grass as you walk on it. Going to ask today if that rubber needs to be refilled in once in a while.
Here are the nails: big bad boys...

 

Even better, the rubber grit is made 100% from recycled tires, so that adds another plus to synthetic lawn installation. No water, no fertilizer, no weeds, no mowing. And reuses rubber tires which are a terrible product to put in land fills as pure waste. Costs a lot, but lasts 20-30 years, if not abused.
