I came to concrete later than most. I spent years in other work, then learned the trade on a finishing crew, out on driveways and slabs with a trowel in my hand. In 2021 I started South Lake Tahoe Concrete, a concrete contractor based here in South Lake Tahoe, CA. We're still a small crew, and I still answer the phone myself.
Finishing taught me early that the top of a slab gets all the attention, but the subgrade, the packed ground the slab sits on, decides whether it stays flat. So does where the water runs. A slab poured on raked dirt can look fine the first week and start sinking a winter or two later, so the dull prep work is where I spend my time.
Most of our calls come from homeowners, along with some property managers and small business owners. What they want from a contractor is a straight answer on cost and a straight answer on timing, even when the answer isn't what they hoped to hear. I'd rather give you the bad news up front than have you pay for a shortcut later.
