Questions people ask
How many concrete contractors are there in Portland?
The Census counted 9 concrete contractors with employees in Portland, OR in 2023, plus 297 self-employed businesses in Multnomah County.
Why does concrete crack?
Concrete shrinks as it cures and moves with temperature and soil. Control joints guide cracks into straight lines. Poor base prep or drainage causes worse cracking.
How long before I can drive on a new driveway?
Ask your contractor. It depends on the mix and weather, but usually it is longer than for walking on it.
Should I repair or replace damaged concrete?
Small cracks and shallow damage can often be repaired or resurfaced. Sinking, heaving or widespread cracking may need replacement.
