Paver Walkway Replacement, from the subgrade up
Pulling a failed walk and rebuilding the base under it.
What actually goes wrong
When a paver surface goes wrong in Florida, the pavers are rarely the thing that failed. Water got into the base, the base moved, and the surface followed it down. Fix the surface only and you are back in two years.
Most of what we dig into across the region is sand, with limestone below it. That combination drains fast most days. Give it a storm that dumps two inches in an hour, though, and water has nowhere to go quickly enough, so it moves through the base and tests every shortcut in it.
Tree roots lift more pavers than people expect. They chase water and the base holds water, so once a root grows into that layer it keeps raising the surface above it.
That is why the schedule on our jobs is mostly spent on the part you will never see again. The surface takes a day or two. The ground it sits on takes the rest, and the ground is what you are actually paying for.
How we run this job
We come look at it
Step one is a visit. Someone from our crew walks it with you, watches how water moves across the property, and gives you an honest read. Sometimes that read is good news.
You get the plan in writing
Scope, materials, schedule, and cost on paper before a shovel moves. The number you approve is the number, not an opening position.
We build the base first
Excavation to the depth this job actually needs, aggregate compacted lift by lift, bedding screeded flat. The slow part, and the part that decides whether the surface is still flat in ten years.
Pavers go down and get cut in
The field goes down to the pattern, edge cuts happen on site, and the perimeter gets a restraint so nothing creeps.
Joints get filled and the site gets cleaned
Sand swept in and compacted, surface washed, debris hauled by us. You get the property back the way we found it, minus the problem.
Why walkways move before anything else
A walkway is a trip-hazard question before it is anything else. People walk it in the dark, carrying things, not looking down. A quarter inch of lift is enough to catch a toe, and on a commercial property that is a liability question as well as a maintenance one.
Walkways are narrow, which makes edge restraint proportionally more important. There is less field to hold itself together, so the perimeter is doing more of the structural work than it does on a wide surface.
Roots are the usual reason a walkway moves. A path that runs past mature trees is running through their root zone, and roots follow the moisture a paver base holds.
Compaction in lifts is the difference between ten years and two.
Polymeric sand binds when it is wetted and resists washout better than plain sand, which is why it has become the default. It has to go in dry, get swept properly off the surface before wetting, and be watered in the way the manufacturer specifies. Rushed installation is why some jobs end up with a hazy residue over the pavers.
Packed sand wedges each paver against the ones around it. Step on one and the joints push part of that weight sideways into its neighbors, which is how loose units end up behaving like one surface. If the joints wash out, nothing is passing load across anymore. Every paver carries itself, and a paver carrying a car tire on its own is the one that rocks and cracks.
Fall
About an eighth to a quarter inch of drop per foot, heading away from the building. You will never feel it. The water will.
Restraint
A perimeter edge restraint is what stops the field creeping outward and the joints opening from the outside in.
Joint sand
Structural, not cosmetic. It transfers load between units, which is the whole reason a field of loose pavers behaves like a surface.
More walkway work
We take this work all over the region. Some of the places we are in most often:
What it asks of you afterwards
Pavers that went down on a proper base do not ask for much. Every so often, look at the joints. If the sand is low, refill it, and if leaves or dirt are packed in, clear them out. Watch for settling and deal with it while it is small.
If you like the look of freshly wet pavers, sealing gets you close to that all the time. It also makes stains easier to lift and helps hold the joint sand. What it asks of you is a recoat every few years and some care in choosing a product, since the wrong one can look plasticky or trap moisture. We will be straight with you about whether yours needs it.
The thing worth acting on quickly is a trip hazard. A lifted edge of more than about a quarter inch is something somebody will catch a toe on, and on a commercial property that is a liability question as well as a maintenance one.
Concrete pavers cover the biggest share of what gets installed. They are pigmented through the body of the unit, so the sun fades them gently and evenly over time. New ones look a touch different from how they will look after a year or two, since the color settles as they cure out. Shapes and colors run wider than any other paver.
Clay brick keeps its color essentially forever because the color is the fired clay itself. It costs more, comes in fewer shapes, and it is the right answer when you want a surface that looks the same in twenty years.
Concrete in the midday sun can get uncomfortable on bare feet. Travertine stays noticeably cooler, which is the main reason it is the paver people ask for around pools. The tradeoffs are that natural stone varies from piece to piece and that it should be sealed anywhere it is likely to get oil or heavy staining.
What we see when somebody else did it
These are the mistakes you cannot catch by looking at a fresh install. That is exactly what keeps them in circulation.
Skipping the geotextile
Geotextile fabric is a thin layer that does a big job. It sits on the subgrade and keeps the native soil out of the aggregate base. Leave it out and the fines work their way up over time until the base is half dirt, and then the surface starts to sink.
Using the wrong sand in the bedding
Bedding wants sharp, angular concrete sand. Rounded mason sand or beach sand behaves like ball bearings under load and lets the pavers wander.
Sealing too early
Give new concrete pavers time before sealing. They have to cure and let efflorescence work its way out. Sealing during the first month risks catching that white bloom under the sealer, where it stays for good.
Laying over the old surface
It is the shortcut that costs the most later. A new surface on top of a failed one goes down fast and cheap, and it still sits on the same ground. If the base caused the original failure, the overlay hides it for one season.
The edge restraint is the piece nobody thinks about and the reason the field holds.
Common questions
Do I need to be home while you work
No. Many of our customers come home to a finished section after work. Just make sure we can reach the area and have a water source. Surprises get a same-day call.
Will the new pavers match what I already have
It depends mostly on whether the line is still made. If it is, we can usually get close, though sun and age shift the color of concrete pavers a little over time. If it has been discontinued, we show you the options before ordering, and that can include borrowing units from a less visible spot.
What happens to the old surface
You do not have to deal with it. Our crew breaks out the old surface and hauls it away, and the concrete and pavers are recycled wherever a recycler is available. Haul-off is already in the scope.
How do you keep it from settling again
Settling is a symptom. The cause is almost always water or a weak base, and occasionally a tree root. We correct whichever one it is, rebuild the base where it failed, and then relay the pavers, so the spot has no reason to drop again.
Do you work with HOAs and property managers
Yes, HOA and condo work is part of what we do. We prepare submittals for the board and phase the job so residents still get in and out. Tell us your approval steps and we follow them.
Do you cover Miami, FL
Yes, Miami is our home area. Tell us where the property is and what you are thinking about, and we will give you a realistic idea of when we could be there.
Tell us what you are looking at
You do not have to book anything to get an opinion. Describe the problem over the phone or send photos, and we will tell you what we see and what it takes to put it right. Sometimes the right call is to wait a year, and we will say so.
Quality you can stand on
