Asphalt and concrete contractor in Sonoma County

Grinding 112,800 SF down 2 inches and paving it back is about getting the grades right before it's about paving. Elevations have to carry across the whole lot so water still reaches the catch basins afterward and every entry apron and gutter line still meets flush.

Get that wrong on a big lot and you've traded an aging surface for a new one that ponds, and that will wear out faster than what you removed.

Careful sequencing keeps the center open. We grind, pave and reopen each area before moving on to the next, instead of closing the whole lot.

Sonoma gets more winter rain than the East Bay, which means a shorter, busier construction season. Asphalt and seal coat both need dry conditions and warm enough temperatures.

If crack sealing has been put off, a wet North Bay winter is what turns open cracks into base failure. Sealing cracks before the rains is one of the cheapest things you can do for a Sonoma County lot.

Asphalt has to arrive within its placement temperature range. On longer hauls, staging trucks so material reaches the site hot and in order is a real part of the quality of the finished surface, not just a logistics detail.

It's one of the things Rocky Stich of R.V. Stich Construction pointed out: correct batching at the plant, and staging the trucks so the asphalt holds its temperature before it's placed.

We did the Rancho Cotati work for R.V. Stich Construction, a general contractor we've worked with for more than seven years.

Good subcontracting comes down to relationships: holding the agreed date and flagging site conditions early instead of sorting them out later.
