I bought a farm. I have an outbuilding with a concrete floor. I want to make it into a barn so I need the concrete gone and 4-5 inches of crushed stone so animal waste accumulates not.
But this is the mother of all concrete. I tried an electric jackhammer and it was 4 hours before I dented six square feet to a depth of two inches.
Now I have a Skid Steer with a hydraulic breaker. I'm down 6-8 inches and no sign of dirt. I'm hitting lattices of rebar and layers of gravel. The breaker is just making holes and there are no cracks radiating from the properly spaced holes. There is no justification for this level of reinforcement.
I can't get through it. This was meant to support planets. Help!

We have an old wooden deck at the back of our house that we want to remove and replace with a brick patio. It turns out that under the deck is a solid concrete set of steps. We need to get ride of them. How can we do that economically? [more inside]

I'm trying to put up shelves on a wall that, I believe, is drywall over concrete. I made holes for plastic anchors, but the drywall part isn't deep enough for them to fit. Help, I'm about as handy as the two I have at the of my arms! [more inside]

I'm getting estimates for repairs to a retaining wall in south Minneapolis; the web's awash in listings, but I'm hoping that some MeFites have worked with and had good experiences with some contractors they could recommend. The wall in question is about 10 feet high and holding up my neighbor's yard, so this is more of a structural thing than a cosmetic thing.

I'm the new owner of a 1950-built home in Whitefish Bay, WI. While doing some landscape regrading around an addition put on sometime after the initial construction (which we think included an expansion of the basement), we discovered this mysterious concrete slab
buried underneath some bushes, next to one of the basement windows. Why is it there? And is it doing something important? [more inside]

I recently bought a new house. One of the things I liked about the house was that the backyard was a blank slate -- fairly large, but nothing "done." It's just an expanse of concrete, with some edge areas covered with either tan bark or stones to keep weeds out.
I thought I'd hire a landscape architect to help me envision nice landscaping and plan something great out there. But I ran out of money! Whoops.
So, I turn to the hive. Hive, how would you improve a backyard that is mostly just (quite ugly) concrete, on a budget? I don't love entertaining in a prison yard. [more inside]

I recently moved into a loft in a really nice building. One issue I'm up against is that I am not permitted to drill any holes in the walls or concrete ceiling.
I have been using the 3M Command strips and hooks and they work well for small things.
However, even the hooks rated for 3 lbs failed to hold my very light-weight surround speakers.
I also have a display case for my shot glass collection that weighs 21 lbs before even adding the glasses to it. I am thinking that may just have to live as a resting, rather than hanging, display.
But I would also like to hang a lightweight pendant style lamp over the area I've set up as my living room. The ceiling does have some concrete protrusions that extend down from it. Would some hardware like a C clamp be solid enough to hang something like that from? Other suggestions? And recommendations for hanging artwork besides the Command products?

I am in the process of replacing my almost 20 year old asphalt driveway with concrete and am looking for some advice on what I should be looking out for when picking a contractor.
One guy quoted me $5.75/sq. ft for a 4.25" thick driveway, rated at 6500PSI. Another guy quoted me $6/sq. ft for a 6" thick driveway at 4500PSI. Both will be reinforced with steel rebar and I am doing just under 900 sq. ft. This will be completed in the Twin Cities, MN metro area so it will have to withstand the harsh winters the years we do have them.

I want to use my unfinished basement as a workout space and have laid down some interlocking foam tiles on the bare concrete floor.

How can I set up a comfortable workout space in a typically humid but not wet basement without having to lift the tiles every couple of months to scrub out the mildew? [more inside]

Looking into building a house near Golden/Boulder CO area. Planning on using ICF's. Looking for suggestions of almost any kind. Would like the house to be about 2000sqft. Am a teacher and worked construction for several summers (but only w/ stick built houses) a few years ago so I will have some time and rudimentary knowledge. Trying to keep the house as simple as possible to keep costs down. Simple rectangular shape and roof and trying to avoid the need to any custom building supplies. If we keep it under $300,000ish we won't need financing. Is it possible? [more inside]

My Driveway is long.... Very long around 8/10 of a mile. I want to concrete the whole thing but it's too cost prohibitive. As an alternative I'm thinking about pouring it as two parallel tire track widths. I'd like to research this but am having trouble finding the right search terms. Is there an industry term for this type of driveway? Has any one here done this what are the pros and cons? [more inside]

A contractor is planning to come out this week and replace a substantial portion of my driveway. It (was and) will be a concrete driveway. The same contractor ('s father) will also be doing a substantial amount of tuckpointing. I live in Cleveland and as you know this is mid-November. Should I be concerned about the cold/snow/rain affecting the durability of their work? What should I expect them to do to adapt to the weather? Should I just try to get them to wait until Spring?

Why does so much of the concrete work here eventually mold? (I am in the Yucatan)
If that is the right word for this action. The discoloring.
Is there an admixture missing? Something that is used elsewhere? how much is to be blamed on the humidity?
People elsewhere are experimenting w/ new mixtures (i. e. fly ash) to make less wasteful, lighter etc.; in this area, is anyone experimenting w/ new formulas?
What is the difference between exposed formwork say, in the US, and here?
Oh, and one more. Could 'rammed earth' construction be done here? What is the raw ingredient necessary?
There is alot of limestone here.
