Concrete Paver Installation without the part that fails later
The workhorse unit, laid on a base built to carry what runs over it.
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.
The ground under most of the region is sand sitting on limestone. It sheds ordinary rain easily. The trouble comes with the heavy afternoon storms, the ones that put down two inches in an hour, when the sand cannot drain fast enough and water starts carrying it out from under 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.
None of this is visible in a finished photo, which is why the cheap version and the right version look identical on day one. They stop looking identical around year two.
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
When pavers sink, it is almost always the base that went first. We build the base before anything else, digging to the depth your job needs and compacting aggregate in lifts under a screeded bedding layer, so the surface stays flat for 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
Sand swept in and compacted, the surface washed down, and the property left the way we found it. We haul our own debris.
What a proper installation actually involves
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.
Short version: the base gets as deep as the load needs. Foot traffic is light, so a walkway sits on a shallower base. A driveway is a different job the moment a loaded pickup parks on it every day, and a commercial drive taking delivery trucks is a bigger one again. We measure for the heaviest of those your surface will see. A contractor who quotes a garden path and a driveway at the same depth skipped that step.
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.
The pavers are a wearing surface. The base is the building.
Plain sand in the joints works until the first few hard rains start carrying it away. Polymeric sand binds when wetted, so it stays in the joint, and that is why it is now the standard choice. The binding is also the risk. Any of it left on the paver faces when the water goes on will set there, so we install it dry, sweep it clean, and water it in to the manufacturer’s spec.
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.
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.
Compaction
Thin layers, each one compacted before the next goes on. A thick dump with one pass of the plate leaves loose stone hiding under a firm skin.
More installation work
This service runs across our whole region. Some of the areas where we do the most of it:
What it asks of you afterwards
The main job is the joints. When the sand drops below the edge of the pavers, add more. When leaves collect in them, sweep them out before they rot and start growing weeds. A properly built surface really does not need much beyond that.
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.
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 have only recently become common on homes. They are very dense and take on almost no water, so stains have little to hold onto. The catch is the install. Porcelain shows every flaw in the bedding, so the base has to be exact, and cuts need the right blade and a slow hand.
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
These are the mistakes you cannot catch by looking at a fresh install. That is exactly what keeps them in circulation.
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
When someone asks us to pave over what they have, we look at the old surface first. If the base is why it failed, an overlay keeps that problem and puts a nicer face on it for a season. Quick and cheap, and still broken underneath.
Skipping the geotextile
Fabric between the ground and the base is a small step that keeps the base doing its job. Sandy soil especially wants to wash up into the stone layer above it. When it does, the base loses its strength and you get low spots that come back no matter how often they are reset.
Using the wrong sand in the bedding
Using whatever sand is on the truck is a common shortcut. Bedding has to be sharp, angular concrete sand, because rounded mason or beach sand lets pavers drift once weight goes on them.
If nobody talks to you about drainage, they are quoting a different job.
Common questions
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 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 work with HOAs and property managers
Yes. If your board only meets monthly, we plan the job around that meeting. Submittals and phased work that keeps residents moving are normal for us, so tell us how approvals run.
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.
Have somebody come look at it
Send a couple of photos or just call. We will tell you what we think is going on, what it would take to fix, and whether it needs doing now or can wait.
