Can you lay grass turf over a concrete base?

Question

i'M GUESSING YOU WOULD NEED SOME TOP SOIL? IF SO HOW MUCH?

IS IT POSSIBLE OR WOULD IT DIE?

Answer 1

hire a kango {concrete breaker}from a builders merchants, about £40 per day, then airate the soil under, u can use a fork, before laying the grass. dont forget to water straight after

Answer 2

No you would have to rip up the concrete remove all the hard core get a rotivator take out all the stones rake it even then lay the turf final give it a very good watering top soil is not needed

Answer 3

If at all possible you should knock out the concrete. Even with 6" of topsoil (that's enough for the roots) there isn't much water reserve. In a real lawn the roots only go down 3-4" but water from further down comes up to help keep water for the roots when you go awhile without rain. Additionally the temperature of that area will be higher because the concrete will retain heat longer because it doesn't hold as much water as soil. Higher temp means the water evaporates quicker.

You could try it with 6" but I think you'll smack yourself in the future for doing it.

Answer 4

Even if you put down a fair depth of top soil then i think the grass would only grow for a short number of years because the soil would become root bound and the grass wouldn't get any nutrients so the best thing would be to dig up the concrete and make a more permanent job...

Answer 5

You need to get rid of the concrete. For a reasonably strong man that's not an extremely big job. You break the concrete up with a sledge hammer. If it doesn't break, you keep hitting it in the SAME SPOT until it does. Then you can fill in with plain ordinary dirt until everything's level when you put the sod down. Don't forget to keep the sod watered or it will die. That's particularly true if you plant it in the spring or summer.

Answer 6

You can, but it will die.
If it's all level with no runoff, I'd put down 4 inches of topsoil or it may stay too wet. If there is some drainage, a couple inches could work.
We work on turf which is over garages all the time. Cement with a rubber barrier. No problem with enough topsoil.

Answer 7

It would be better to break up the concrete & make a decent job out of it instead of, throwing on a foot or so maybe two of topsoil ,that will wash away after settling down in no time at all.

Answer 8

yes you were right,you need some top soil mixed with sand and compost (3:2:1).for the best result you got to find clayey top soil,so its can retain water for grass.if you planning just to plant ground cover (grass), 1 feet thickness is enough.you need a regularly watering each morning and evening also dint forget to fertilise grass with 15:15:15 compound fertiliser and compose.good luck.

Answer 9

Geez, at least 6" of soil at least I'd think , you'll have to water a lot. too much work to get rid of the concrete?

Answer 10

Bit of a stupid question really, NO unless you can put a considerably amout of topsoil on top of the concrete.
