Patio Replacement & Extensions
Patio Replacement in Salt Lake City, UT
Plenty of Salt Lake patios were poured as an afterthought: a small square off the back door, thin in places, no gravel under it, and a slope that sends water toward the house. A few winters later they are cracked across the middle, sinking at one corner, or flaking where the snow sat. Other times the slab is sound and simply too small for the way the family uses the yard now. Those are two different jobs. A tired slab usually gets replaced, while a healthy one that just needs more room can often be extended.
Replacement starts by breaking the old concrete out and hauling it away, then figuring out why it failed. Soft spots are dug out, gravel is brought in and compacted, and the new slab gets formed with the slope it should have had. Extensions are drilled and doweled into the existing slab with steel so the new section stays level with the old one. Color is the honest catch: new concrete will not match a weathered slab, so many people choose a contrasting border, a stamped addition or a resurfacing across both pieces so it looks planned.
What's included
What goes into patio replacements and extensions
- 01
Breakout and haul-off
The old slab broken up, loaded and hauled away, along with small steps and landings being replaced.
- 02
Failure check
A look at the soil, base, slope and downspouts so the cause of the old cracks is not poured right back in.
- 03
New base and slope
A compacted gravel base and forms set so the new patio drains away from the house.
- 04
Doweled extensions
Steel dowels drilled into the old slab so an extension stays flush with it.
- 05
Design joint
The seam between old and new treated as a border, band or pattern line.
- 06
Finish options
Broom, troweled border, stamped and colored, or a resurfaced finish over old and new together.

How it works
Patio Replacement & Extensions, step by step
- 1
Replace or extend
We look at cracks, settling and flaking to judge whether the existing slab is worth keeping.
- 2
Break out or drill
Old concrete is removed, or dowel holes are drilled along the edge of the slab that stays.
- 3
Prep and pour
The subgrade is fixed, base compacted, forms set, and the new concrete placed and finished.
- 4
Blend and seal
Joints are cut, borders finished and sealer applied so the patio reads as one space.
Questions
Patio Replacement & Extensions questions
Why did my old patio sink at one corner?
Most often the soil under that corner was loose fill or got soaked again and again, from a downspout, a sprinkler or melt running off the roof. Clay and silt soften when wet, and backfill near a house can keep settling for years after construction. The fix is removing the weak soil, compacting a gravel base and sending the water somewhere else.
Does extending cost less than replacing?
When the existing slab is sound, extending usually costs less because nothing is broken out or hauled away. If the old patio is cracked through, sinking or badly flaked, adding on just ties new concrete to a failing piece, and replacement is the better use of money. The free estimate weighs both options on your actual slab.
What happens before an old patio comes out?
Furniture, planters and anything mounted on the slab get moved, and access is planned for breaking equipment and hauling. 811 is called to mark buried lines, and HOA rules on size or color are checked if the patio is growing. If a hot tub or gas line sits on or near the slab, it is flagged early.
Can you resurface my patio instead of replacing it?
Sometimes. A resurfacing overlay can renew a slab that is structurally sound but worn, stained or scaled on top. It will not fix a patio that is cracked through, sinking or heaving, because the new layer follows the old slab wherever it moves. The estimate visit is a good time to sort out which you have.
How much bigger should my patio be?
Bigger than feels necessary on paper. Most people who extend find the original slab fit a table but not the chairs pulled out, a grill and a path past both. Adding 6 to 10 feet in the right direction often changes the whole space. Lay a garden hose in the new outline and live with it for a weekend before deciding.
