Answer 2

Laying Turf On Concrete

Answer 3

Actually the person who mentioned the use of turf on roof top patios and gardens is quite correct. You can grow grass on top of a cement pad as long as it is somewhat raised, this will allow for drainage. I have seen and had to remove grass that has covered entire patio slabs. As long as you use a shallow rooted grass, fescue is a possible species, lots to choose from in that family. Most lawn grass only roots down to about 3-4". Pasture grass and haying grasses are a whole different game. Make sure you have a good quality soil base down, 20% sand, mulch and soil will work best. Use Seed and Sod starter fertilizer, has low nitrogen and contains bonemeal to encourage a strong root system before laying down the turf. If possible use an underground watering system to maintain the moisture levels needed. I know wishfull thinking. Other wise water thoroughly early in the morning daily until established. The cement will heat the turf up faster than that on the ground so watering is going to be essential. Good luck.

1. how is the soil going to stay in the area, do you have a guard or rim that will keep it from running off when you water your plants. If that is why you are doing this.
2. if you can find a why to keep the soil in place you need to decide what you will be planting and how deep the roots will grow. you need to have the soil that deep.
3. where is the water going to go when you water the plants. are you making a makeshift are that prevents the water from leaving (if the water runs so can the soil). then you have to plant only plants that are good in wet soil, unless you have a hot climate which can dry the soil in quick amount of time.
4. you will probably have to plant something like grass where the roots lock together so it will keep most of the soil in place as well.

I had problems with with an area of stones in my front yard. I dug at least over a foot and still nothing but stones and dirt. So I flatend out as much as I could and put a 3-4 in layer of dirt over it. Then I planted grass seed. The stones allow the roots to grow as long as they want and they get the enrichment from the soil as well, since grass roots grow down and sideways it locked everything in place and no one can tell there were any stones there.

good luck

Answer 5

It can be done. Monaco play their football on a pitch laid over a underground car park. It receives many complaints regarding the condition of the pitch, and if it were simply a lawn, it would be fine. Drainage is the critical factor, land drainage pipework would be required, and a good depth of topsoil. Old WW2 airstrips, and standings have become lawns. This involves a lot of work, with not predictable results, but with some thought it is possible.You will need perhaps 6"+ of topsoil, but water logging MUST be avoided.

Answer 6

Yes, you would need to break up the concrete first for drainage purposes and to allow the grass roots to pass through. Then cover with 1.5 to 2 inches of riddled top soil before laying the turf. (This is the wrong time of year to be laying new turf,early April and mid September are the best times to lay turf as there is less chance of it drying out)
Hope this helps.

Answer 8

I once had a similar problem to this.Yes, you can grow turf over concrete, or virtually any substance. On the concrete, I used a little over 4 inches of topsoil.
However, you haven't indicated how deep this level of concrete is. Very deep concrete may need a different amount of soil.

Answer 11

Yeah but it wont really stay firm to the ground because the turf won't bind with the soil because theres concrete there it also depends how thick the concrete is.
