What goes into a patio that lasts
Most early patio failures trace back to what happens before any concrete arrives: the base. Front Range soils often contain expansive clay that swells when wet and shrinks when dry, so sub-grade preparation, compaction and drainage away from the foundation matter more than the finish on top.
For exterior flatwork in a freeze-thaw climate, air-entrained concrete, correct slab thickness, and properly spaced control joints are the standard practice. Joints give the slab a planned place to crack instead of a random one.
Finish options
Broom finish — the classic slip-resistant texture, and the most economical option.
Colored concrete — integral color mixed through the slab, so wear and chips don't reveal gray underneath.
Stamped concrete — patterns such as flagstone, slate or wood plank pressed into the surface. See stamped & decorative concrete.
Exposed aggregate — the top paste is washed away to reveal the stone in the mix, giving a durable, textured surface.
