Can I raise a concrete block on my walkway without breaking it?
Q. A piece of my front walkway has sunk 3 1/2 inches on the side closest to the house. So we step very far down when we step off of the stoop onto this walkway. This concrete front walkway is made out of separate squares of concrete. The squares are about 3 x 4 feet and 3 plus inches deep. I know nothing about concrete, but I was thinking of digging out underneath this sunken block and jacking it up with my car jack and then loading dirt underneath. Will the concrete break when it is jacked up? Do you have any advice as to how to fix my problem? One person said to add a small concrete step on the end of the sunken slab so we don't have so far to step down. Is that a better idea?

A. Ha ha ha...lol lol lol. Sorry, was just reading tickettorides answer to this question. You know, ticket to ride...the guy that speaks for all contractors in a three state area. He had a good point when he said novices shouldn't answer questions on here, only experts like him. So I looked into his profile to see what else he was an expert at. Seems he's an expert on trolls, C-Sections, loose stools in 4 year olds, getting evicted, and so on and so on. Anyway, like others have said, you could repair the slab, but replacing would be the better solution in the long run.

Is concrete at 2500 psi adequate for garage floor & driveway?
Q. I got a quote from a concrete contractor who is proposing to pour 2500 psi concrete to form my garage floor and driveway (about 1,000 sq. ft. total combined area). My question, is 2500 psi strong enough or should I request a stronger grade? They're planning to add rebar for added strength. The quotes were based on 4" thickness (seems to be the typical for So. Calif.) just parking two sedans, no extra heavy vehicle types. garage floor is 21' x 20', and driveway is 21' x 30'. I received quotes ranging from $6 to $8. so 2,500 psi is adequate?

A. In Texas, we specify 3,000 psi concrete for residential driveways and slabs. The typical thickness is 4 inches unless the homeowner wants something thicker. The cost between 2,500 & 3,000 concrete should be minimal since the design mix is only altered by some additional cement to the mixture.

How to prepare soil for a concrete patio?
Q. 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.
Asked by djasail - Thu Jun 1 13:44:41 2006 - - 5 Answers - 0 Comments
A. The newly updated standards for ground-supported monolithic concrete flooring is to ONLY use vapor barrior when it is an area that is air-conditioned. So, if your patio is "open-air" like a porch and garage, and will not have conditioned air above it, then do not use any vapor-barrior. Stand firm on this, as vapor barrior pushes too much water to the surface during concrete curing and can cause more cracks then needed. Dampen the ground before placing the concrete so that the dirt does not wick moisture away from the fresh concrete. This will also help in cracking. Vibrate the concrete, if you can, by tapping on the form-boards with a hammer. Place #4 rebar at a minimum of 12 inches on center, and tied at intersections with wire-tie [cont.]

Does mudjacking concrete work, or is it more cost effective to re-pave?
Q. 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.

A. Mudjacking would be used for foundation repair. If that is what you need, go for it. If not, tear it and repave it, make sure your base is compacted firm and not too wet, use a low water cement ratio, and utilize rebar for extra reinforcement.

How strong an ultrasonic wave has to be to conduct a testing on concrete?
Q. My friend is working on his thesis which is to measure concrete density by using ultrasonic wave. The wave's frequency is 50 kHz and the concrete is 15 cm thick. He calculates the density of the concrete by measuring how fast the wave propagates through the concrete. So, he emmits the wave on one side of the concrete and a receiver receives the wave on the other side of the concrete. The problem is the wave cannot penetrate the concrete. Can really a ultrasonic wave penetrate a concrete? How strong (in voltage) should the wave be to penetrate?

Three and a half feet is 42" (about) and the standard step risers are 7 1/2"- 8", so that would be a cast step of 4-risers, and 4-12" treads. 8" from deck to first tread, down three more treads, then 8" to walkway.

A. It largely depends on your Water to Cement Ratio, if you make it really wet, it may take longer to dry. If you do not make it so wet, it should dry very fast, I have seen crews pour sidewalks and then let people drive onto them in about 7 hours. They had to drive on them to get to their driveway.

A. Adding such a thin layer of concrete would not hold up to being driven on. Grinding down the existing driveway will make it thinner, so that is not a good idea. Home depot sells bags of asphalt repair material. It is a sticky, asphaltic cement you could use to create a slope and since it is flexible, will not break off like concrete would.

A. no...ur wasting ur time and money...what ur doing is called 'forming" and the material ur thinking of using is not going to hold the presure of the concrete...i dont know how high u wnat to go but we form out of plwood and reinforce with 2x4 along the top and bottom and up the sides and then have to put n 45 deg. bracing... lic. gen. contractor

What is the difference between concrete design mix strength and compressive strength of concrete?
Q. Does the addition of admixtures and plasticizers to concrete influence it's strength?
Asked by suraj k - Thu Oct 18 05:33:35 2007 - - 3 Answers - 0 Comments
A. The design mix strength comes from the recipe, and the compressive strength results from the test (usually crushing) to ensure that the recipe was correct. All additives ( and setting temperature) affect the strength of concrete

How do you preserve a concrete statue that is exposed outdoor?
Q. I have a 1-foot tall concrete chicken statue that I decorate my garden. Since it is exposed to weather, over time, the paint peel off and some of the concrete is chipped. How do I fix it so that it will last long?

A. I have several concrete statues and fountains in my yard which I have used several manufacturer's paints to spruce up over the years. I've found that the Patio Paints and sealer last about the longest even when exposed to water spraying from the fountains. You really have to wire brush off all of the peeling paint on the statue before starting and use the primer and the sealer after painting for the best adhesion. I have pieces that I painted 10 years ago out there that have weathered better than the ones on which I used concrete paint from the home improvement centers.

How do i make a water tight concrete aquarium?
Q. I plan to make a concrete aquarium (above ground). I want to have a glass window on one side. I have no experience in any kind of glass-work. My question is, can i make a concrete tank with a hole and buy of the shelf a glass sealant and stick the glass to the concrete? will this work?

A. Ever been to an aquarium, like Sea World? That's what they are. To make the tank, you'd probably do it in two pours, unless you're set up to pour a mold, which you probably aren't. You just pour the base (floor) first and embed 'water stop' halfway into the concrete. That's a rubber strip either 4" or 6" wide. Half gets embedded in the floor, and the other half sticks up for when you pour the walls. I'd also add butyl water stop before pouring the walls. Looks like a big piece of licorice and sets on top of the floor before the second pour. It expands as the concrete cures. You can use either, but both is double protection. After pouring the floor, just form up the walls and frame a box in where the window will go. Drill some 3/4" hole… [cont.]

How do you prep a concrete floor for painting?
Q. I have an outdoor patio with a concrete floor that I want to paint. I already bought paint specifically for concrete/patios/floors. How do I prep the surface? Do I really need a pressure washer or would a good sweeping suffice? Best details will get the "best answer". Thanks!
Asked by eyedoc999 - Sat Feb 3 02:09:34 2007 - - 3 Answers - 0 Comments
A. follow the manufacturers directions on the paint can, and give them the points. To the best of my knowledge there shouldn't be much prep work other than to make sure the concrete has fully cured, and, is clean, and free of foreign objects. But like I said, follow the manufacturers instructions.

Will putting a concrete patio right next to my foundation be damaging to the foundation?
Q. I had a concrete patio put in last summer. They said they were going to be putting in the expansion joint that goes between the patio and the foundation on the house but when they were finished they didn't put it in and told me it wouldn't be necessary. Now after the thaw, (I am in MN), the patio top is chipping away because it shifted along the foundation. Is this going to cause problems for me? I am afraid my foundation may have been weakened by this.

A. could be future trouble for the foundation...they only told you it wouldnt be necessary because they forgot it...see if they cant come back and cut a relief joint next to the wall and caulk it to keep water out...
