How Paver Installation Is Actually Done: Base, Compaction, Drainage and the Work Behind the Quote

A finished paver driveway can look like a pile of manufactured bricks arranged neatly on the ground. The part you see, however, is only the wearing surface. The performance of an interlocking paver installation depends heavily on excavation, subgrade condition, compacted base, grade and drainage, bedding sand, edge restraint, cutting, joint filling, and compaction.

The process in one line

Plan elevations/drainage → excavate → prepare subgrade → place and compact base → establish final grade → install restraints → screed bedding sand → lay/cut pavers → compact → fill joints → compact again → clean and inspect. Sealing is a separate maintenance/appearance decision, not the structural step that makes the pavement work.

Permit, right-of-way and licensing check

Do not assume that a paver project is permit-free because the visible material is not structural concrete. Driveway construction, widening, resurfacing, work in a public right-of-way or easement, drainage changes, lot grading, retaining conditions, and related site work can trigger permits or reviews. The exact answer is local and depends on the complete scope.

Charlotte County illustrates the distinction: it publishes a residential driveway permit for driveway construction on private property, and separately requires a right-of-way permit for driveway installations, reinstallations or resurfacing within county rights-of-way or easements. Another Florida city or county may administer the same kind of project differently, so verify the address and scope with the authority having jurisdiction before excavation.

If the project requires a permit, ask who will pull it, what inspections or drainage/site reviews are involved, and what document will show the permit is closed. A capable homeowner may qualify for an owner-builder permit for some work, but an owner-builder permit is not a way to hire an unlicensed person to act as the contractor. See the Florida Surface-Job Licensing & Permit Matrix.

1. Start with elevations, drainage and what connects to the new surface

Before excavation, determine where water should go and how the finished surface must meet the garage slab, street, sidewalk, pool deck, drains, doors, landscaping, and neighboring property. A visually attractive paver field that sends stormwater toward the house is not a successful installation. Local right-of-way, drainage, pool, utility, or permitting requirements can also affect the complete scope even when ordinary paver installation itself is not a DBPR-licensed construction trade.

2. Excavate enough material for the complete pavement section

The installer is making room not only for the paver thickness but also for bedding material and the engineered/selected base below it. Excavation depth therefore depends on the project, soil, loads, drainage design, paver thickness, and base specification. This is also where the “simple” job begins producing a pile of material that must be moved and disposed of.

3. Evaluate and compact the subgrade

Soft, saturated, organic, disturbed, or inconsistent soil can undermine everything installed above it. The subgrade is shaped to the required elevation and slope, weak areas are corrected as needed, and the soil is compacted with equipment appropriate to the space and soil. Open areas may use larger compaction equipment; confined areas around walls, curbs, utility structures and other obstructions may require a mechanical tamper or smaller plate.

Compaction is not simply “make it look hard.” CMHA guide specifications recommend density criteria tied to standardized Proctor tests—for example, at least 98% Standard Proctor density for pedestrian areas and residential driveways, with heavier vehicular work commonly specified against Modified Proctor density. A Proctor percentage is a density target, not a knob on the compactor. On work where density is specified or important, field testing is how the contractor verifies the prepared soil or base rather than judging only by footprints or appearance.

4. Build the base in controlled lifts and compact each lift

This is one of the major pieces of hidden work. Aggregate base is spread in lifts—layers shallow enough for the selected compactor and material—then compacted before more base is added. The crew makes repeated overlapping passes across the lift rather than dumping the full base depth and vibrating only the surface. Moisture condition matters too: material that is excessively dry, saturated, segregated, or contaminated can be difficult to compact consistently.

The exact lift thickness, machine size, number of passes and moisture condition are not universal numbers; they depend on the aggregate, required density, compacted depth and compactor manufacturer. This is why a proposal that says only “install base” leaves out important information. Ask what base will be used, what the compacted thickness will be, how it will be placed in lifts, what equipment will compact it, and how the crew will know the required density and grade have been reached.

What compaction actually looks like on the job

Subgrade: the exposed soil is shaped, unsuitable soft areas are corrected, and the soil is compacted before base aggregate is placed.
Base aggregate: aggregate is spread in controlled lifts. A vibrating plate, reversible plate, roller, rammer or other suitable compactor makes repeated overlapping passes over each lift before the next lift is placed.
Edges and obstructions: areas beside curbs, walls, utility boxes and other places a larger machine cannot reach require smaller compaction equipment rather than being left loose.
Grade check: elevation and slope are checked as the base is built. The bedding sand is not supposed to become a thick filler used to hide a poorly graded base.
Installed pavers: after laying, the pavers themselves are vibrated into the bedding sand with a plate compactor. CMHA calls for a low-amplitude plate compactor capable of at least 5,000 lbf of centrifugal force for conventional interlocking concrete pavers, generally with multiple passes.
Joint filling: dry joint sand is swept into the joints and the pavers are compacted again until the joints are properly filled. A protective pad may be required on the plate for some paver surfaces.

The common shortcut to understand: a thick loose base can feel hard at the top after a few passes while deeper material remains inadequately consolidated. If that lower material later densifies under vehicles or rain-related movement, the finished pavers can settle with it.

5. Establish the grade in the base—not by making the bedding sand thick and thin

CMHA specifically warns against using bedding sand to compensate for an uneven base. The final paver surface follows the base. Low spots should therefore be corrected in the base rather than hidden under extra sand that can later consolidate differently.

6. Install edge restraints where the pavement is not otherwise restrained

Interlocking pavers depend on lateral confinement. CMHA describes edge restraints as essential because they help prevent the field from spreading under traffic and other horizontal forces. Restraints can take several forms, but they belong in a planned system and should not be treated as a cosmetic finishing strip.

7. Screed the bedding sand uniformly

CMHA guidance uses a nominal 1-inch uncompacted bedding layer for conventional sand-set interlocking concrete pavers and specifies appropriate bedding-sand gradation. The sand is screeded over the prepared base and should not be repeatedly walked through and patched after it has been leveled.

8. Lay the field, maintain the pattern and make the cuts

The visible part of the work now begins. Lines and pattern have to remain controlled while the installer works across the prepared bed. Perimeters, drains, curves, columns and transitions create substantial cutting. A paver saw or masonry saw, layout tools, string/laser references, handling equipment, and practiced cutting technique can matter as much to appearance as the full pavers in the middle of the field.

9. Compact the installed pavers into the bedding layer

CMHA calls for vibration with a low-amplitude plate compactor to seat the pavers and begin forcing sand into the lower portions of the joints. Its current guidance specifies at least 5,000 lbf of centrifugal compaction force for conventional interlocking concrete pavers and multiple passes. A protective pad on the plate may be required for pavers whose faces could be scuffed or etched. Broken units are replaced rather than hidden under joint sand.

This is not the same job as compacting the aggregate base. The base machine has to densify material below the finished surface; final paver compaction has to seat the units without damaging their faces, disturbing unrestrained edges, or losing the laying pattern.

10. Fill the joints and compact again

Dry joint material is swept into the joints and the field is compacted again until the joints are filled to the required level. The exact sand can vary by system; conventional joint sand, stabilized products, and polymeric products have different installation and water requirements. Do not assume the joint material is simply whatever sand was left over from another part of the job.

11. Inspect elevations, drainage, edges, cuts and transitions

Before calling the project complete, look for rocking units, inconsistent joints, low spots, damaged pavers, weak edges, poor transitions, and drainage problems. A hose or natural rainfall may reveal water behavior that is difficult to judge by eye alone.

Before deciding to install pavers yourself

The useful question is not only “Can I lay pavers?” It is “Do I want to manage the excavation, material handling, compaction, grade, cuts, disposal, rentals, weather and property disruption for my first installation?” A capable DIYer should be able to answer the questions below before ordering pallets.

Have I checked permits, right-of-way limits and buried utilities? Excavation should not begin until the legal work area is clear and utility locating requirements have been handled.
Where will the excavated material go? Soil, old concrete, sod and failed base occupy real truck/trailer volume and may need paid disposal.
Can delivery trucks and equipment reach the work area? Pallets of pavers, base aggregate and sand need staging space that does not destroy the area needed for excavation and grading.
What compactor will I use for the subgrade and each base lift? A small plate that is convenient to rent may not be appropriate for every soil, base depth or lift thickness.
How will I measure elevation and slope? Decide whether you can confidently use string lines, a long straightedge, laser level or other grade-control method before the base is covered.
How will I make the cuts? Curves, borders, drains and garage transitions can require many cuts. Masonry and concrete cutting can generate respirable silica; wet cutting or other appropriate dust-control methods should be planned rather than improvised after the saw arrives.
Can I keep prepared bedding protected? Screeded bedding is not a storage or walking surface. Rain, foot traffic and delays can force rework.
Build an equipment list before a material list. The pavers may be the obvious purchase; the compactor, saw, loader, screeding equipment, hauling, disposal, PPE and dust/water control can change the economics.
Estimate calendar time, not only labor hours. Deliveries, rentals, weather, learning, cleanup and material shortages can turn a weekend estimate into a long-running construction site.
Decide how long the driveway or patio can be unusable. A project can be technically manageable and still be badly timed if family is visiting or vehicles need access.
Consider the recovery job. A poor pattern can be relaid. A poorly compacted base, wrong elevations, or drainage problem may require lifting large areas and rebuilding from below.
Hybrid work is possible. A capable homeowner may choose to hire excavation/base preparation and perform the laying, or handle demolition/cleanup while an installer controls the pavement section. The responsibility boundaries should be explicit.

What you are paying a professional crew for

The visible laying speed is only part of it. A competent crew brings production equipment, material-handling capacity, familiarity with grade and drainage, repeatable compaction, cutting skill, and the ability to keep a large installation moving without leaving prepared bedding exposed for days. Surface Blueprint does not assume that a higher price proves better work; the proposal should identify enough of this hidden work that two quotes can actually be compared.

What is being excavated and where will it be disposed of?
What is the compacted base material and thickness?
How will the base be placed and compacted?
How are final elevations and drainage being established?
What bedding material and nominal thickness are being used?
What edge-restraint system is included?
What joint material is being installed and what maintenance does it require?
Are sealing and joint stabilization included, optional, or excluded?
How will access to the garage, driveway, pool or entry be affected and for how long?
Who corrects settlement, spreading or drainage defects during the workmanship-warranty period?
