Never consume something you're unsure of. But don't waste food, either. There are plenty of things that are safe long after their sell-by dates. Maybe you aren't the type to eat around the mold, but here are 10 things you can safely eat past their expiration dates.
Basic concrete slab cost. I'll base my price on what my actual estimate would be to install a 6 thick concrete slab for one of my customers. Base cost for a 6 thick concrete slab -- $4.00 dollars per square foot --. Take the length of the concrete slab x the width of the slab to get the. total square footage. Multiply the total square footage by 4 (dollars) to get the total price.
To actually pour the slab (place and finish is the usual term) will cost about $0.55 per square foot of surface area; another $345.00 on top of the other costs. This will bring the total of your slab, based on the prices in my area, to around $1500 to $1800, in place and finished. don't know the current rate for concrete in your area; in my area it's about $120 per cubic yard. Roughly $920, plus the delivery charge of $125.00, if they charge that in your area. You will have to have forms set, to hold the concrete while it sets up.
