Stupid question maybe, but I would like to know if it is possible to grow grass over a concrete slab? Details: I live in Baltimore City and have a very tiny and uninspiring concrete slab patio (enclosed by a fence) behind my rowhome. The concrete slab has a concrete border approximately 7 inches higher than the slab itself. Note: It’s not feasible/affordable to break up the concrete and start anew. Just wondering if there is a way to put down a shallow amount of soil and roll sod grass over it? Is artificial grass my only option?

My darling hubby and I are planning on pouring a concrete slab patio. We have a patio door that exits to this patio and needs about a three and a half foot flight of stairs. DH and I are a little confused about the most cost efficient way to construct steps. We want something that will go well with the concrete or patio stones so I don’t believe wood will work very well and we’re not sure exactly how to set up a frame to pour steps, set brick steps or build a frame that we can disguise with patio stones and concrete slab treads. I have enclosed a few links to pictures for the latter of the options. Thank you for any help!

I need to install a pier Foundation under existing concrete slab.
I was told that I can install some 36 inch piers under my existing concrete slab porch in order to enclose the porch inside my home. Can I do this by pouring the concrete on the side on the slab or do I have to take some of the slab up, install re-bar , etc. Any masonry tips would help.
If I excavate under the slap, should I use a sonatube, and how do I pack it so the bottom of the slab touches the pier?

Seems to be in the winter or after a lot of rain. Happens to concrete patio too. A white residue forms and then the concrete or blocks start to slowly fall apart.

I need some to hold up real good in the weather. Can I use regular kilts as my base coat or do I get a concrete primer & use concrete paint?

Concrete nouns are nouns we can touch, such as apples. However, paper is a common noun. We can touch paper why isnt it a concrete noun or a common concrete noun?

I am planning to have a concrete patio poured at my new house. How can I be sure the contractor is properly preparing the “underlayment” before pouring the concrete? I know that a certain amount of dirt should be removed (about 8″), that 3/4″ gravel and fine gravel should add back about 4″ when compacted, and that there should be a pre-soil treatment as well as a vapor barrier installed before the rebar goes down, but what else should I be sure gets done before the 4″ thick concrete gets poured?

Also, what PSI rating should the concrete be for this type of application?

I am in the Southern California area, in case weather is a concern.

I am in a pinch. We jsut bought this farm and until we build a big barn we have to put our horses in a mechincal shed with a concrete floor. The concrete floor is smooth and the horses with their shoes will no doubt slip and slide. My question is what is the best recommendation for turning a slick concrete floor into a not skid floor. That I can perform myself. Where can I get the equipment with out hiring it done. It is only about 20 by 40 floor so it can be done in a weekend. Let me know your thoughts and ideas would be welcome. With in reason.

I have some slopped concrete that I would one day like to get fixed. I’m wondering if mudjacking works, or if I’d be better off just re-paving the concrete instead. One contractor told me that mud jacking is very expensive and just a short-term fix.
