The cement may not have been sealed properly, which would allow water to seep in the small cracks. In the winter the water freezes and expands causing the cement to crack and crumble. the finish on the concrete was not done correctly.trowel finished pushing the stones down from top of surface then sealed. concrete setting up before finish steps done.

Yes
Can you glue cement back together?
A lot depends on the stress factors and use that it's going to get. I've glued pieces to small concrete walls with 'thin set' cement and that works well as long as it's not subject to people jumping on on it like a step. I've also repaired edges of steps this way, but it seldom lasts a year. So far, I haven't found an actual 'glue' that works better with cement than 'thin set' .
What year did Thomas Edison invent cement?
Thomas Edison DID NOT invent cement! From Rutgers University's "Edison Papers" collection we learn the following: "While attempting to develop his ore milling process to concentrate low-grade iron ore, Edison found that he could sell the waste sand to cement manufacturers. In 1899, he decided to investigate how he might transfer his rock-crushing technology to the production of Portland cement. During the next few years, Edison made other improvements in cement manufacture, the most important of which was a long rotary kiln that he licensed to other manufacturers, as well as using at the automated plant he built in Stewartsville, New Jersey. The kiln helped lead to overproduction in the industry and the Edison cement plant was never very profitable. Edison Portland cement was used extensively for buildings, roads, dams, and other structures, including Yankee Stadium. Edison also designed a system for building inexpensive cement houses that he planned to license to other manufacturers. Only a few of these were ever built." http://edison.rutgers.edu/cement.htm
What are the uses of waterproof and water repellent portland cement?
Just look around to see all the uses of concrete in our daily lives! Concrete made of Portland Cement is a subject to all types of degradation starting with Carbonation as soon as it comes in contact with the atmosphere. The thing most people overlook is that when concrete is placed, the water in the mix in addition to hydrating the concrete, is trying to evaporate out of the matrix to the atmosphere. In doing so, Bleed water is expelled to a surface. The channels this water travels through is called a gel-pore or capillary system. Once the water is gone -- this capillary system remains open allowing contaminates to enter the concrete. Concrete is a Big Sponge that breaths for years after it is poured. A sealer to protect it is Vital to Longevity. Choose a sealer wisely. Surface membrane type sealers don't last! Stay away from a sealer that cautions Do Not expose to metals or glass. That is a Sodium Silicate based product that is gone in less than a year! Any sealer that allows for another coating at some future date?? Doesn't this beg the question of "What happened to the first application"? Get a penetrating sealer to seal the gel-pore system, that doesn't form a film membrane and has a 15 year warranty for water proofing.
What is Portland cement used for?
Portland cement is used to make concrete. And concrete is what we build things with. No large structures could exist without it, and concrete is used even in the construction of most smaller structures - like houses. Concrete forms a foundation or footing for most structures in modern societies. And aside from its use in concrete, cement is used in motar for applications in masonry. We also make stucco out of it, and stucco is an exterior finish for many homes and small structures. Additionally, most "regular" grout for tile and stonework is made from cement. The "fuzzy" term infrastructure includes roadways. Imagine roadways with no concrete. How about influent and effluent waterways? Most of these are built with concrete. We could go on, but we'd be here all day. Concrete is all around us. We just don't see it unless we look for it. Start looking and thinking about it and see what you can see.

What should i choose asphalt or concrete for my entrée de garage(driveway)?
We have had both. Concrete tends to look better and hold up longer, but the surface stones can pop out and the concrete can crack. It is more expensive to install than concrete. We paid additional for a formula that would have fewer surface pops. New asphalt driveways look nice, too. There are pros and cons to sealing them every year. Sealants give the driveway a new look but don't necessarily prolong the life of the driveway. The surface of an asphalt driveway can become uneven and will crack. Tire pivot points will wear and tire depressions will form where vehicles are regularly parked. The dark color can be a heat sink due to sun exposure and can actually soften with the heat That can be a negative during a hot summer, but our south-facing asphalt driveway seemed to finish snow removal jobs by melting whatever remained. Asphalt is less expensive, but generally needs to be replaced more often than concrete. Some folks have gone to using paving bricks in driveways. That looks nice, but you have to fight weeks growing in the cracks and it makes for a noisy and bumpy ride for anything wheeled across it. (think wheeled garbage bins or luggage). Whichever driveway you choose, you need to do your homework on the proper installation and watch that your contractor adheres to those parameters. Also check the contractor's guarantees and reputation. We had to take one contractor to court because an asphalt driveway was installed cold and didn't last a year.

Our house was built 2.5 years ago and our neighbor's house was done 2 years ago About 1 year ago our neighbors had a survey done and found out their driveway goes through our property What do we do?
There is a range of possibilities, depending on how long you plan to stay and whether or not you want to be friendly with your neighbors: * You can sell them the land under the driveway, which could also allow them to tear out the driveway and put in something worse, * sell them an easement to use that part of your property to cross your land, which also means it can be used as a driveway forever, * license this particular owner to use the driveway (or the driveway easement) either annually, or until they sell the house or remove the driveway, * ask them to move their driveway, or * sue them for trespass and force them to move the driveway. Whatever you do, put it into writing and have a local real estate attorney review it for you. If you completely ignore the problem, it will not go away, and the longer you wait, the more rights the neighbors may have (laches, estoppel, easement by prescription, adverse possession).

How can you stop weeds growing through gravel driveway?
Lately I have been wondering how much damage pine needles and leaves will cause to a gravel driveway if not raked or blown away in the fall and left to sit and decompose. I have a sneaky suspicion that the leaves and needles break down year after year and deposit quite a bit of soil into the gravel if left unattended. This year I decided to rake it all up. We'll see. Anyone else have an opinion?
What are the advantages of artificial putting greens?
