It is called "Rollrasen". Here is a company that supplies a product called "Rollturf Royal". I think I picked up the brochure at the garden centre near our house. They told me they can install if for me. I forget the price....I must have fainted when they told me. It is very tempting though...grass so quickly. I just wonder how long you have to keep the dogs off of it.
Here is the supplier.

We had to reseed a corner of the garden last year where we removed an old tree root. I put down the seed and a net to protect it but the birds still had a great time. Eventually the seed took but it seemed to take forever. Then we filled in another section, didn't use green mesh and the birds never went near it. It's fine, though a lot of clover coming through lately.

This Spring, if Spring ever gets here, we still have to reseed a large section that didn't take last year as it was too late in the season when we tried. We put a fleece on it to control the mud over the winter which has been really effective. Now I have noticed some grass coming through the fleece and when the weather gets better we will lift the fleece, add more seed, and then fence off the area to keep the dogs off so the new seed will take, I hope. The dogs will be mad. It's the part at the front of the house and they love to see what is going on- kids walking by, horses, other dogs. We are thinking we might seed in two stages so as not to frustrate the dogs so much.

We are still undecided about what to do with the immergrun since it is not dense enough to be nice. I would prefer grass but it's a slope. I just think grass will be easier for the dogs and not muddy in winter, which the immergrun is. So I will dig up the immergrun but not sure what I will do with it....perhaps at the front outside of our fence where everyone else's dog leaves a P-mail message. I know others put rocks around the lamp post, but it doesn't look very nice.

I hope you find a good solution.
