Paver Courtyards, from the subgrade up
Enclosed courtyards where the pattern has to work from every angle.
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.
Most of the region sits on sand over limestone. That sand drains quickly in normal weather, then hits its limit in a heavy downpour, when two inches can fall in an hour. A base built for that holds. One that was not starts to wash out.
Moisture collects under a walkway, and roots go where the moisture is. Ficus, black olive and a lot of older shade trees root shallow and wide, so they find that damp layer and push the pavers up.
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
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, 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
Dig to depth, compact the aggregate in layers, screed the bedding. Nobody ever sees this part again, which is exactly why most failures start here.
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 outdoor rooms do to a surface
Heat is a real material constraint around fire features. Some units spall when they take repeated direct heat, so the ring immediately around a fire pit gets specified differently from the field around it.
Outdoor living surfaces get treated as furniture rather than pavement, which is exactly how they fail. A kitchen run takes grease and heat; a fire feature takes heat and foot traffic in the dark; a lanai floor lives under a cage that concentrates runoff.
Under a screen enclosure the cuts have to be clean to the track and the drainage has to work with the cage rather than against it. Water coming off a cage lands in a line, not spread out, so it concentrates in one place.
Water is what ends most paver surfaces, and it rarely arrives from the sky.
When water stands on pavers, the slope is usually the reason. A paver surface should fall about an eighth to a quarter inch per foot away from the building, a pitch you cannot feel underfoot that still moves water off. Flatten it and puddles form. Tip it the wrong way and runoff ends up at the foundation.
Drainage is the cheapest thing to fix while the ground is open and the most expensive thing to add later. Once water leaves the paved surface it has to land somewhere, and on a tight commercial lot with no fall to work with, that takes planning. We look at a channel drain along the low edge, a permeable section over a stone reservoir, or regrading the planting bed next door.
A downspout that discharges right at the edge of a paver surface puts a whole roof’s worth of water into one small patch of base every storm. Irrigation heads that spray the same spot twice a day and runoff from a neighboring grade do similar damage. Compared with those, rain falling across a properly jointed surface is minor.
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
Compacting the whole base in one go only firms up the top. We place aggregate in layers and compact each one, so the base is solid all the way down.
More outdoor work
This is work we do throughout the region. Here are a few of our most frequent areas:
What it asks of you afterwards
Owners are often surprised how little a properly built paver surface needs from them. The joints are where most of the attention goes: keep them full of sand and free of leaves that would otherwise rot in place. Beyond that, keep an eye out for any area that starts to sink.
Sealing really is a preference, which is why you hear different opinions on it. Our view: it is worth it where the surface takes oil, food or heavy staining, and less worth it on a walkway that only sees foot traffic. A poorly chosen sealer can leave a glossy sheen or trap moisture underneath, so product choice matters as much as the decision itself.
People walking across pavers are rarely looking at their feet, which is why a raised edge matters. More than about a quarter inch of lift is enough to catch a toe. Deal with that one quickly, especially on commercial property, where it is a liability concern along with a maintenance one.
If staining is your main worry, porcelain is close to stain-proof. It absorbs almost nothing. It asks more of the installer than most materials, though: an uneven bed shows through, so base work has to be precise, and cutting it cleanly takes the proper blade and some patience.
Pick a paver at random from our jobs and it is probably concrete. You get the widest pick of shapes and colors, and a unit that lays predictably. Because the color is mixed into the concrete, it fades slowly with sun and does not peel or wear away. Early on it does drift a little as the pavers finish curing.
Clay brick costs more than concrete pavers and offers fewer shapes. What you get for that is color that does not fade, because the color is the fired clay itself. If the surface needs to look the same two decades from now, brick earns its price.
The shortcuts that surface two years later
Every one of these looks fine on the last day of the job. That is why contractors keep getting away with them.
Laying over the old surface
Paving over an old surface is a lot like painting over rust. It goes quickly and costs little, and the problem underneath keeps working. If the base caused the first failure, the new surface will show it again within a season or so.
Skipping the geotextile
This one cannot be checked after the fact. Once the pavers are down, nobody can see whether there is fabric under the base. If there is not, fine soil gradually moves up into the aggregate and weakens it, and the settling that follows takes a full rebuild to fix.
Using the wrong sand in the bedding
Bedding sand that is round acts like a layer of ball bearings. Pavers set on mason or beach sand drift under load. Sharp, angular concrete sand stays put.
Sealing too early
Sealer works like a lid. Put it on a new concrete paver too early, in the first month, and whatever efflorescence has not come out yet gets trapped underneath as a permanent white haze. Let the pavers cure first.
Compaction in lifts is the difference between ten years and two.
Common questions
How long does the job take
A typical paver courtyards 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
Not at all. With access to the site and a water source, we can work whether you are home or not. The one thing we will not do is make a big decision without you, so if something unexpected shows up, we phone you the same day.
Will the new pavers match what I already have
You will know before we order anything. Plenty of repairs match exactly. Others come close, since concrete pavers shift color a little with sun and age and older lines get discontinued. When close is not good enough, we can move units from a less visible area onto the visible patch.
What happens to the old surface
Old surfaces come out completely before anything new is built. We haul the debris away and recycle the concrete and pavers wherever we have a recycler to take them. Nothing about removal gets billed as an add-on.
How do you keep it from settling again
Settled pavers almost always point to something underneath. We trace it, whether it is drainage, a soft base or a root moving in, and fix that first. Pavers go back down only once the reason for the dip is gone.
Do you cover Miami, FL
We do. Miami, FL is home base for us, and our crews are in the area most weeks. Call with what you have in mind and we will be straight with you about timing.
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.
