Problem: Write an article based on this summary: Measure out the space you wish to fill with concrete. Mark the height you want the concrete to reach. Use the measurements to calculate how much concrete you will need. Install braces around where you will pour the concrete. Prop up the braces with wooden stakes. Test the evenness of the boards by laying a bubble level on top of them. Lay wire mesh between the braces.

Answer: Taking measurements is necessary if you plan on filling a large space. Use measuring tape to figure out the length and width your new slab needs to be. Write your measurements down so you know what supplies to get to pour a smooth, consistent slab later. If you are only going to pour a thin slab or patch up existing concrete, make a general estimate of the area's size and how much concrete you need for it. You can usually mix and pour a small batch without setting up a perimeter. Slab thickness is important and depends on your plans for your home. If you want the slab to reach up to your doorstep, for instance, you need to measure from the existing slab to the bottom of the doorstep. Use chalk to mark the height the slab should reach. Take your time measuring. The ground beneath the existing concrete may not be level, so measure on all sides. Measure the length, width, and depth of the area you wish to fill. Multiply these numbers together to get a general estimate of the amount of concrete you need. Add an extra 10% onto your total estimate to account for spillage. The calculation can be an imperfect estimate, especially for areas that aren't perfect squares or rectangles. Always get more concrete than you need to ensure you have enough. Using your measurements, cut some boards to help hold the liquid concrete in place. You can get wood boards that will reach the depth marks you made in chalk earlier. Set the braces up around the perimeter of your old concrete slab. These braces serve as a mold. When you pour the concrete into it, you no longer have to worry about it spilling off the old slab and making a mess. It gives you a better chance at creating a strong, level slab. You can cut the wood yourself with a circular saw. Wear protective gear, including a dust mask and eye protection, if you do this. Alternatively, get the wood cut at a home improvement store. Dig out the soil around the braces, then stand the stakes in them. You can use 2in 4in (5.1cm 10.2cm) wood for most projects. Place the stakes approximately every 12in (30cm), then drill them to the braces with 3in (7.6cm) wood screws. Make sure the stakes are planted firmly in the dirt so the braces don't fall as you work. If your slab won't be very high, you may be able to lay the wood braces on the ground and screw them together without using stakes. The braces should be even before you begin pouring the concrete. Set the level on top of each board 1 at a time. Watch the liquid in the center of the level to make sure the bubble stays in the center. If the bubble moves to 1 side, that side is lower than the other side and needs to be adjusted. Another way to test the boards is to run string behind them. The string should be the same distance from the board at all times. If 1 end is closer to the string than another end, the brace isn't straight and should be adjusted. Wire mesh provides extra strength to thick concrete slabs. You can purchase a roll of welded wire mesh at a home improvement store, then simply spread it out in a single layer over the old concrete. Press it down so it is flat and level before you add the new concrete. The new concrete you pour binds to the mesh. Although it makes the concrete stronger, it won't prevent it from cracking. Another option is to get rebar and lay it out in a grid pattern similar to the mesh. Place rebar chairs underneath the rebar to hold them in place.

Try resetting your Blackberry Try using another USB cable or USB port on your computer if your computer or Blackberry Desktop Software fail to recognize your Blackberry Curve.

Answer:
Lack of storage space can often prevent Blackberry Desktop Software from successfully updating your device software. Try deleting text messages, third-party applications, Internet browsing history, and other data you no longer need to free up memory on your device. if updating your device results in software malfunction. In some cases, a corrupted update or an update that fails to complete can cause software problems, but performing a reset can help restore your Blackberry to a working state. In some cases, faulty hardware can interfere with your being able to update your Blackberry.
