Very small projects can be completed in one day while larger projects may take multiple days. Small to mid-size projects often have a phase/day for demolition and form setting and a separate phase/day for pouring and finishing. Most commonly [...]
The work can be phased to re-direct traffic during demolition, placement, and curing. If this approach is not practical, metal trench plates can be used to cover and protect new concrete while it cures. For some other applications, use [...]
Most concrete mixes are referred to by the amount of cement (the “glue” or binder) holding the aggregates together in each cubic yard of the mix. Most mixes for sidewalks, curbs, gutters, driveways, slabs etc range from 5 to [...]
Rebar serves several purposes. Dowels and longitudinal strands are simple means of typing together new concrete with existing so that they move together rather than independently. Rebar grids, commonly at 12”-24” on center are placed in load bearing slabs [...]
As a general rule, most sidewalks and driveway approaches do not contain rebar. With all concrete structures (whether slabs, curbs, etc) if there is vertical displacement at cracks, there is no rebar.
In general, yes. Good design and construction result in fewer cracks and more predictable and controllable location of them. Concrete structures generally consist of a combination of expansion joints to allow for expansion and contraction of the concrete and [...]
