Paver Sealer Stripping, from the subgrade up
Stripping a failed or hazed sealer before putting anything new down.
What actually goes wrong
The failure is almost always below the pavers. Sand washes out of the joints, water gets down into the bedding, the bedding migrates, and the surface drops. Everything you can see is downstream of that.
Our ground is sand over limestone in most of the region, and sand drains fast right up until it does not. Add an afternoon storm that drops two inches in an hour and the base either handles it or it starts washing.
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.
We would rather lose a bid than skip the base work, because the base work is the job. Everything above it is finish.
How we run this job
We come look at it
Somebody from the crew comes out, stands on the problem, and tells you what is actually going on underneath it. No sales visit, just a look and an honest read.
You get the plan in writing
Scope, materials, how long it takes, and what it costs, written down before anybody starts. No verbal numbers that change later.
We build the base first
The base comes first and gets most of our attention. Excavation goes as deep as the load requires. Aggregate is compacted layer by layer, then the bedding is screeded flat. You will not see any of it once the pavers are in.
Pavers go down and get cut in
Laying the field is the fast part. The care is in the cuts at the edges and the restraint that locks the whole field in place.
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.
What a proper installation actually involves
Base depth works both ways. Digging a garden path out like a truck drive spends your money on stone nobody needs. Laying a driveway on a path’s base saves money for about a season. People on foot need the least, a pickup parked every day needs more, and a commercial drive taking delivery trucks needs the most. Matching the depth to the load is the measurement, and it is the part guessers skip.
The difference between a base that holds and one that sinks often comes down to a bit of extra time. Building it in lifts means spreading aggregate a few inches at a time and compacting each layer fully. Skipping that saves time on the day and costs the owner later, when a crust that was compacted only at the top lets the loose stone under it settle. You cannot see which method was used once the pavers are down.
A paver surface is really four layers and only one of them is visible. Under the pavers there is a thin bedding course of sharp sand, screeded dead flat. Under that is the base, which is compacted crushed aggregate and does the actual structural work. Under that is the subgrade, which is whatever your property is made of. The pavers on top are a wearing surface. They spread load and they look good, but they are not what holds the thing up.
Water is what ends most paver surfaces, and it rarely arrives from the sky.
On a flat commercial lot, a channel drain across the low edge is often the cleanest answer. It catches sheet flow before it reaches a doorway or a parking stall. Where there is no fall to send water anywhere, a permeable section can let it soak through into a stone reservoir underneath, and sometimes the right move is regrading the planting bed alongside. We decide that during design, while it is still easy.
People expect rain to be what wears out their pavers. In practice, a field with properly filled joints sheds most rainfall without trouble. The failures trace back to concentrated water: a gutter dumping at the border, irrigation hitting one spot day after day, or the neighboring lot draining across the corner.
Every paver surface we build is pitched away from the building at roughly an eighth to a quarter inch per foot. You will never feel that slope when you walk across it. Water does feel it, and it runs off the edge instead of sitting in puddles or heading back toward your foundation, which are the two ways a bad grade shows itself.
Joint sand
Structural, not cosmetic. It transfers load between units, which is the whole reason a field of loose pavers behaves like a surface.
Separation
Geotextile between subgrade and base stops fine soil migrating up and destroying the aggregate structure.
Base depth
Set by what the surface carries, not by habit. A walkway and a truck-bearing drive are not the same excavation.
More installation work
We take this work all over the region. Some of the places we are in most often:
What it asks of you afterwards
Think of sealer as a coat you can choose to put on, and then have to keep putting on. It helps the joint sand stay put and gives stains less grip. Pick the wrong product and you get a shiny, plastic look you will not like, or a film that holds water under it. We tell people plainly when theirs is better left alone.
A lifted edge is the one problem worth fixing the week you notice it. Past about a quarter inch it becomes a trip hazard. Catching it early usually means resetting a few pavers. On a commercial property, waiting also means carrying a liability question until it is done.
Debris in the joints is the thing to stay ahead of. Leaves and grass clippings break down into soil, and soil in a joint is where weeds start. Sweep it out, keep the sand topped up, and a well-built surface will ask very little else of you.
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.
Travertine gets requested for pool decks because it stays noticeably cooler than concrete under bare feet in the sun. It does want a sealer if the area sees oil or heavy staining, and as a natural stone, expect variation from one unit to the next.
How this gets done badly
Nothing on this list shows when the work is new. Each one waits a while before it surfaces, which is how it keeps getting repeated.
Sealing too early
Everybody wants the new pavers sealed right away. That is the mistake. Concrete pavers need to cure and clear their efflorescence first, and sealing in the first month can lock a white haze under the sealer permanently.
Laying over the old surface
A new surface laid over an old one usually looks fine for about a season. After that, the base that ruined the first surface starts ruining the second. Speed and price are the only things the shortcut buys you.
Skipping the geotextile
Between the native soil and the base, there should be a geotextile fabric. It keeps the two from mixing. Without it, fines migrate into the aggregate until the base weakens, and the settling that follows comes back after every surface repair.
Using the wrong sand in the bedding
Pavers only hold their line if the bedding grips them. That takes sharp, angular concrete sand. Rounded mason or beach sand behaves like ball bearings once there is weight on it.
The edge restraint is the piece nobody thinks about and the reason the field holds.
Common questions
How long does the job take
A typical paver sealer stripping job runs two to five working days once we start. Base work is the slow part; laying the field goes quickly. Weather moves things, and in summer we plan around the afternoon storms rather than pretending they will not happen.
Do I need to be home while you work
You can go to work as usual. We need to be able to reach the work area and use your water. If anything changes the plan, like what we find once the old surface is up, we call you that day.
Will the new pavers match what I already have
What matters most is where the repair sits. In a back corner, a close match is usually fine. By the front door it needs to be better, and if the line is discontinued we can borrow pavers from a less visible part of the surface for that spot. Either way you see the options before we order.
What happens to the old surface
We remove it. Breaking out and hauling the old concrete or pavers is a normal part of our scope, and where a recycler is available, that material gets recycled instead of landfilled.
How do you keep it from settling again
We start with a question: where is the water going? That answer usually explains the settling. From there it is a matter of correcting the drainage and putting a proper base back in, plus handling any root or downspout feeding the problem.
Do you cover Miami, FL
Yes. Being Miami-based means we are in and around Miami, FL almost every week. Ask us about scheduling when you call and you will get a clear answer.
Start with a conversation
Start with a phone call or a few photos. Tell us what you are seeing and we will tell you what we think is causing it and what fixing it involves. If it can safely wait a year, we will say that too.
