Concrete Additions & Extensions in Pearl, MS
Extending an existing driveway, patio, or wall instead of starting from scratch.
Adding Onto Existing Concrete
Not every project needs a full replacement. A driveway that's too narrow for a second vehicle, a patio that's outgrown a growing family, or a decorative seat wall added around an existing slab are all extension jobs — tying new concrete into what's already there rather than tearing it all out.
The tricky part of an extension is the joint between old and new concrete. We match the existing slab's elevation and thickness, and where it makes sense, we use dowels or tie bars so the two sections move together instead of separating — which matters more here given how much our clay soil shifts through wet and dry seasons.
When an Extension Makes Sense
- Existing driveway or patio is structurally sound but too small
- Adding a decorative wall, curb, or seat wall to an existing slab
- A pool or landscaping project needs the existing concrete widened
- You want to avoid the cost of a full tear-out and replacement
Our Process for Additions & Extensions
Assess Existing Concrete
We confirm the existing slab is sound enough to tie new work into.
Match Elevation
New base graded to meet the existing slab at the right height.
Tie In & Pour
Dowels or tie bars placed where needed, concrete poured and finish-matched.
Cure & Walkthrough
We walk the finished addition with you once it's cured.
What Drives the Cost of an Extension
Square footage of the new section, condition of the existing concrete it ties into, and how closely the finish needs to match. We'll be upfront if the existing slab isn't in good enough shape to build onto.
Why Choose A&K for Additions & Extensions
We'll tell you honestly when an extension is the right call versus when the existing concrete is too far gone to build onto — we're not trying to sell you the smaller job if it isn't the right fix.
Additions & Extensions FAQs
Can you extend a driveway that's already too narrow?
Yes — widening an existing driveway is one of the more common extension requests we get, tied in at a matching elevation and finish.
Will the new section look different from the old concrete?
There's usually some visible line where old and new concrete meet — that's normal and expected. We match the finish and joint pattern as closely as possible, but a perfectly invisible seam isn't realistic, especially if the existing concrete has weathered or discolored over time.
Can you add a seat wall or curved edge to an existing patio?
Yes — this is a common way to add usable space and definition to a patio without repouring the whole thing.
Is it cheaper to extend existing concrete than replace it entirely?
Often, yes, if the existing slab is structurally sound — but if the original concrete is already cracked or settling, tying new work to a failing base isn't a good long-term fix. We'll tell you honestly which situation applies.
How do you keep the new section from cracking away from the old one?
We use dowels or tie bars between old and new concrete where appropriate, and place control joints to manage the connection point.
