"Lawn mat" used to drive over lawn without damaging it?

 I am looking for a product that is placed over your lawn allowing a
vehicle to drive over it without damaging it.  I have seen one that is
left in place permanently and the grass grows over the top of it.  I
just can't remember where I saw it and can't seem to find it online.

I have a boat that is parked on the other side of my lawn from my
driveway.  I need a way to get to it with my truck without damaging my
lawn or making a drive way through the middle of it.

Thanks for your help.

 I am not sure about products which you place over, as it would
eventually sink into the soil.

I am trying out a product which is placed in the soil over a gravel
substrate which takes the load.
