Paver Porch Installation, from the subgrade up
Porch floors set flat and drained away from the threshold.
What actually goes wrong
Here is the honest version: a sunken paver is a symptom. The base under it lost material, usually to water, and the surface settled into the gap. Resetting the pavers without correcting the base just buys you a season.
The water table sits high across a lot of the coast, so there is less room for water to go down and more reason for it to move sideways. That is what takes the sand out from under a driveway edge.
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
One of us walks the property with you, looks at where the water goes, and gives you a straight read on what we see. If it is smaller than you feared, we say so.
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
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
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, the surface washed down, and the property left the way we found it. We haul our own debris.
What a proper installation actually involves
Depth is decided by what the surface has to carry. A walkway that only ever sees people can sit on a shallower base than a driveway that takes a loaded pickup every day, and a commercial drive that takes delivery trucks needs more again. Anybody who quotes the same base depth for a garden path and a driveway is not measuring, they are guessing.
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.
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.
Compaction in lifts is the difference between ten years and two.
The sand in the joints is structural. It is what transfers load from one paver to the next, which is the whole mechanism that lets a field of loose units behave like a surface. When joints wash out, each paver starts carrying its own load alone, which is exactly when they start rocking and cracking.
Polymeric sand binds when it is wetted and resists washout better than plain sand, which is why it has become the default. It has to go in dry, get swept properly off the surface before wetting, and be watered in the way the manufacturer specifies. Rushed installation is why some jobs end up with a hazy residue over the pavers.
Compaction
Aggregate goes down in lifts and each one gets compacted. One dump and a quick pass gives you a crust over loose material.
Fall
Roughly an eighth to a quarter inch per foot away from the building. Invisible underfoot, decisive for where water ends up.
Restraint
A perimeter edge restraint is what stops the field creeping outward and the joints opening from the outside in.
More installation work
We cover this across the region. A few of the areas we work most:
What it asks of you afterwards
A paver surface that was built properly asks for very little. Keep the joints topped up, keep organic debris from composting in them, and deal with a settled area while it is small. That is genuinely most of it.
Sealing is optional and it is a preference rather than a requirement. It deepens the color, makes stains easier to lift, and helps hold joint sand. It also needs redoing every few years and a bad sealer choice can leave a plastic-looking sheen or trap moisture. We will tell you honestly whether your surface benefits.
The thing worth acting on quickly is a trip hazard. A lifted edge of more than about a quarter inch is something somebody will catch a toe on, and on a commercial property that is a liability question as well as a maintenance one.
Porcelain is the newest of these in residential work. It is dense, absorbs almost nothing, and is close to stain-proof. It needs precise base work because it is unforgiving of an uneven bed, and cutting it takes the right blade and patience.
Concrete pavers are the workhorse and cover most of what gets installed. Widest range of shapes and colors, most predictable to lay, and the easiest to match later. Color is pigment through the unit, so it fades gently with sun rather than wearing off, though it does shift over the first year or two as it cures out.
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.
How this gets done badly
None of these are visible on the day the work finishes, which is exactly why they keep happening.
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.
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.
Laying over the old surface
It is quick, it is cheap, and it inherits every problem underneath. If the base was the reason the old surface failed, putting a new one on top of it just hides the failure for a season.
Skipping the geotextile
A separation fabric between the subgrade and the base stops the two from mixing. Without it, fine soil migrates up into the aggregate, the base loses its structure, and you get settlement that no amount of surface work will fix.
If nobody talks to you about drainage, they are quoting a different job.
Common questions
What happens to the old surface
We break it out and haul it off. Concrete and old pavers go to a recycler where one is available. That is included in the scope, not added on after.
How do you keep it from settling again
By fixing the reason it settled. That usually means correcting drainage and rebuilding the base properly, and sometimes it means dealing with a root or a downspout that is dumping water in the wrong place.
Do you work with HOAs and property managers
Regularly. We are used to submittals, board timelines, and phasing work so residents keep access. Tell us what your approval process looks like and we will work inside it.
Do you cover Miami, FL
Yes. Miami, FL is inside our regular working area and we are out that way most weeks. Call and we will tell you honestly when we could get to you.
Is there a warranty
Yes, in writing, covering our workmanship. Manufacturer coverage on the pavers themselves comes from the manufacturer and we will hand you that paperwork too. We will also tell you plainly what a warranty does not cover, like a new root or a changed drainage condition.
Can you work around my pool being open
Usually. Pool deck work gets staged so you keep a safe path and the water stays covered while we cut. If there is a stretch where the pool has to be off limits we tell you which days up front.
Let us walk the property
Call and describe it, or send pictures. You will get a straight answer about what is wrong and what it takes to put right, including when the honest answer is that it can wait a year.
Quality you can stand on
