Florida Lanai Pavers done so it stays flat
Lanai floors for the way Florida houses actually get used.
What actually goes wrong
Almost every paver problem we get called out to is a base problem wearing a surface disguise. The pavers themselves are fine. They are concrete or stone, and they will outlast most of us. What moves is what is underneath them.
In a dry climate a so-so base can last for years without showing its faults. South Florida is less forgiving. The sand under most properties shifts when water moves through it, and the rain comes in heavy bursts. Each wet season finds any weakness in the base.
Mature trees are the second cause. Roots go where the water is, and a paver base holds moisture, so they grow straight into it and push the surface up.
So the real question to ask anybody bidding this work is not what pavers they use. It is how deep they excavate, how they compact, and where they think your water goes. The answers tell you everything about how long the job will last.
How we run this job
We come look at it
We come out and see it with you. The walk covers the surface and where the water goes after it leaves. You get a plain answer, and if the fix is smaller than you feared, we tell you that first.
You get the plan in writing
Everything in writing up front: what we are doing, what it is made of, how long it takes, and what it costs. Nothing changes without you signing off on it.
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
Field laid to the pattern, edges cut on site, and a restraint set around the perimeter so the field cannot creep.
Joints get filled and the site gets cleaned
Joints filled and set, everything washed down, our own debris on our own truck. The site is yours again the same day we finish.
What salt air and a high water table do to a surface
Think of the pavers as the finish floor and the base as the foundation. Nobody would judge a house by its tile, and a paver job works the same way. Underneath what you walk on there is a thin bed of sharp sand screeded flat, then a thick layer of compacted crushed aggregate, then the native subgrade. The aggregate is what actually holds the weight. The pavers wear well and look good, and they ride on everything below them.
The same paver can go on a garden path or a delivery drive. What changes is everything under it. People on foot put very little load on a base, so a walkway can sit shallow. A driveway with a loaded pickup on it every day needs more depth, and a commercial drive that takes delivery trucks needs the most. Picking the paver is the easy decision. Sizing the base is the one that gets measured.
Loose aggregate under a hard crust is the failure nobody sees coming. It happens when a base is dumped in at full depth and compacted only at the surface. The top tightens up and the bottom never does, and once traffic and water work on it, the loose part shifts and the pavers above it sink in patches. Laying the base in lifts of a few inches, compacting each one, prevents it.
If nobody talks to you about drainage, they are quoting a different job.
Settling at one corner usually has a single water source behind it. Picture a downspout pouring onto the edge in every storm. That edge stays wet, the sand underneath moves, and the corner drops. Irrigation hitting the same patch daily does the same thing more slowly. Rain spread across the whole surface rarely causes that kind of failure.
The grade under a patio or walkway has one job: get water off and away from the building. The pitch that does it is roughly an eighth to a quarter inch per foot. Underfoot it feels level. In a downpour you can watch the water move. Lose that fall and you get puddles, or worse, water running back toward the foundation.
Where the water goes once it leaves the surface is a real design question. On a tight lot with no fall available, that can mean a channel drain across the low edge, a permeable section that lets water through into a stone reservoir, or a regrade of the adjacent planting bed. All of those are cheaper to build now than to retrofit.
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 coastal work
We take this work all over the region. Some of the places we are in most often:
What it asks of you afterwards
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.
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.
Keep an eye on paver edges. A lip of roughly a quarter inch is where a surface stops being uneven and starts tripping people. At home that means a stubbed toe. On a commercial property it also means a liability question, so a lifted edge there should not wait for the next maintenance round.
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.
Porcelain is the material where installer skill shows most. It is dense and close to stain-proof, yet it will not hide an uneven bed, and it takes the right blade and patience to cut cleanly. It has only come into residential work fairly recently.
Concrete pavers carry their color through the whole unit. Sun will mellow it slowly over the years, and there is no surface layer to wear off. Expect some shift in the first year or two while the paver finishes curing, which is normal. This is the material behind most of the driveways, patios and walkways we build, because it is predictable to lay and easy to match later.
The shortcuts that surface two years later
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
If a newly sealed paver job looks cloudy white under the shine, it was probably sealed too early. Concrete pavers need to cure and release their efflorescence first. Sealed in the first month, that haze stays locked beneath the sealer.
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
Bedding wants sharp, angular concrete sand. Rounded mason sand or beach sand behaves like ball bearings under load and lets the pavers wander.
Water is what ends most paver surfaces, and it rarely arrives from the sky.
Common questions
How long does the job take
A typical florida lanai pavers 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
New pavers start out looking newer than the ones already down, because concrete pavers change color a little with sun and age. Sometimes the match is exact and sometimes it is close. When a line is discontinued or the difference is too obvious, we walk you through the options before anything gets ordered.
What happens to the old surface
We take it out and take it away. Old concrete and pavers get recycled where a facility is available, and hauling is built into the scope from the start, so there is no surprise charge at the end.
How do you keep it from settling again
Most of the time it comes down to the base. If it was laid too thin or compacted in one pass, we dig it out and rebuild it in lifts, then check that water is leaving the area the way it should. Fixing the surface without the base just repeats the problem.
Do you cover Miami, FL
Yes. Miami is where we are based, so it is about as close to home as our work gets. Give us a call and we will tell you when we can come out.
Tell us what you are looking at
The water usually explains the problem, so that is what we look at first. We come out, walk the property, trace where the water goes, and write up what we find. It is the fastest way to a real answer.
