Uneven Paver Repair, from the subgrade up
Lifting and relaying the high and low spots back to a flat plane.
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.
Our ground is sand over limestone in most of the region, and sand drains fast right up until it does not. Add an afternoon storm that drops two inches in an hour and the base either handles it or it starts washing.
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.
We would rather lose a bid than skip the base work, because the base work is the job. Everything above it is finish.
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, how long it takes, and what it costs, written down before anybody starts. No verbal numbers that change later.
We build the base first
Excavation to the depth the job needs, compacted aggregate in lifts, and a screeded bedding layer. This is the part nobody sees 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, surface washed, debris hauled by us. You get the property back the way we found it, minus the problem.
Working out what actually failed
Repair starts with diagnosis, not with lifting pavers. The surface tells you where it failed; it does not tell you why. Pull up a sunken section without answering the why and you have bought a season.
The usual why is water: a downspout discharging at an edge, an irrigation head hitting the same spot twice a day, or a neighboring grade sending runoff across a corner. Second most common is a root. Third is a base that was never compacted properly.
A good repair is invisible. That means keeping the units that came up, blending replacements so they do not read as a patch, and matching the joint sand so the repaired area does not sit a shade different from the field around it.
Water is what ends most paver surfaces, and it rarely arrives from the sky.
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.
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
Aggregate goes down in lifts and each one gets compacted. One dump and a quick pass gives you a crust over loose material.
Other repairs we handle
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.
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.
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.
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.
The pavers are a wearing surface. The base is the building.
Common questions
How long does the job take
A typical uneven paver repair 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
No. We need access and a water source. Most people go to work and come home to a finished section. If we hit something unexpected we call you that day, not at the end.
Will the new pavers match what I already have
Sometimes exactly, sometimes closely. Concrete pavers change color a little with sun and age, and older lines get discontinued. If we cannot match, we will show you the options before we order anything, including pulling units from a less visible area to patch a visible one.
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 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.
Tell us what you are looking at
The fastest way to get a real answer is to have one of us stand on it. We will walk the property, look at where the water goes, and write up what we find.
