Permeable Pool Decks, built on a base that holds
Decks that pull water down instead of pushing it at the house.
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.
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.
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
A straight read starts on site. We come out, walk the whole property with you, trace the water, and tell you what we see without dressing it up. Small problems get called small.
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
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
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
Sand swept in and compacted, the surface washed down, and the property left the way we found it. We haul our own debris.
Where the water goes when it rains here
Cut a paver surface in half and the pavers are a thin slice at the top. Beneath them is a shallow course of sharp sand, screeded flat, that the units bed into. Beneath that is the base, a much thicker band of compacted crushed aggregate, which is the layer doing the structural work. At the bottom is the subgrade, meaning the ground your property is built on. Most of the depth, and most of the labor, sits out of sight.
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.
Compaction has to happen in lifts. That means putting the aggregate down in layers of a few inches and compacting each one before the next goes on. Dump the whole depth in at once and run a plate over the top and you get a hard crust over loose material, which behaves fine for a year and then starts settling in patches. This is the single most common corner cut in the trade and it is invisible on day one.
Water is what ends most paver surfaces, and it rarely arrives from the sky.
Polymeric sand needs a dry patio to go into. It is designed to bind when it gets wet, which is why it resists washout better than plain sand, and also why moisture at the wrong moment ruins it. We fill the joints dry, sweep the surface fully clean, then water it in following the manufacturer’s instructions. When that sweep gets rushed, the residue bonds to the paver faces and leaves a haze.
Joints should be filled all the way, and kept that way. The sand in there is structural: it shares load from one paver to the next, and that sharing is what makes a set of loose units work like a surface. Half-full joints wash out faster, and once they do, every paver is carrying its own load. Rocking comes next, then cracking.
Fall
Roughly an eighth to a quarter inch per foot. Flat surfaces hold puddles and backward ones send water at the foundation, so the slope always runs away from the building.
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 drainage work
You will find us doing this across the region, often in these areas:
What it asks of you afterwards
If the base was built right, you will spend very little time on it. An occasional sweep keeps organic material from composting in the joints, and a top-up of joint sand now and then keeps the pavers locked together. That is the list.
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.
Two things to know about travertine. It is natural stone, so expect differences in tone between units. And it stays cooler than concrete underfoot in direct sun, which makes it the usual pick around a pool. If the spot gets oil or heavy staining, add a sealer to the plan.
Porcelain pavers are dense enough to be close to stain-proof, which makes them easy to keep looking new. They are also the newest option in residential work and the least tolerant of a poor base. Any unevenness in the bed comes through on top, and cutting them well takes patience and the right blade.
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.
The failures we get called out to fix
None of these are visible on the day the work finishes, which is exactly why they keep happening.
Laying over the old surface
Whatever made the old surface fail is still down there when you pave over it. If the base was the problem, a new layer on top only covers the failure for a season, and then it shows through again.
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
Sand looks like sand until a truck rolls over it. Sharp, angular concrete sand grips. Rounded sand, the mason or beach kind, rolls under the load and lets pavers slide out of place.
Sealing too early
A new concrete paver needs to cure and let its efflorescence work out before it gets sealed. Seal it in the first month and you can lock a white haze under the sealer permanently.
The edge restraint is the piece nobody thinks about and the reason the field holds.
Common questions
Will the new pavers match what I already have
First we find out whether your paver line is still made. Older lines get discontinued, and even a current one can look a little different from units that have sat in the sun for years. If we can match, exactly or closely, we order. If not, we show you the options first, like pulling pavers from a less visible area.
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
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
Regularly. We phase the work so residents can still reach their doors and parking while each section is rebuilt, and we fit into whatever approval process your board runs.
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.
Is there a warranty
Two warranties apply. Ours covers the workmanship and comes in writing. The manufacturer covers the pavers, and we give you their documentation. Our warranty does not cover conditions that change after the job, such as a new root or a drainage change, and we tell you that up front.
Tell us what you are looking at
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.
