Belgian Block Curbing and Aprons in Smithtown, NY
Belgian block is a rough-cut granite paving block, and around Smithtown it does three jobs: a curb along a driveway edge, a border band framing the drive, and a full apron where the driveway meets the street. The street edge is where it earns its place. NOAA's Islip normals count 98.3 nights a year at or below 32 degrees F and 31.8 inches of snow, so plows, salt and freeze-thaw all meet at the curb. A granite face has no cement paste to scale, the flaking that salt and freezing cause on concrete, and the Town of Smithtown's street standards list cobblestone curb among the approved curb types. The weak points are the concrete bed and the mortar joints. Because an apron sits in the public right-of-way, the road owner sets the permit.
$9 - $11 per ft of edging; $18 - $50 per sq ft for cobblestone paving (national) · full pricing guide
National cost guides price block edging by the linear foot. One guide, updated May 30, 2026, puts Belgian block driveway edging at $9 to $11 per foot and stone curbing at $12 to $40 per linear foot and up, labor included; another lists granite curbing at $11 to $16 per foot for the stone alone. The national guides do not price a block apron separately; the nearest proxy is a national cobblestone driveway range of $18 to $50 per square foot, against $8 to $18 for a poured concrete apron. The estimate moves with block size, whether each block is set in concrete and mortared, tear-out, and at the street the Town permit: $150 per residential apron plus a $150 road improvement initiation fee applied to the total. The Smithtown concrete cost page sets these beside driveway and sidewalk ranges.
A block curb is a small concrete footing with stone on top. One supplier's installation guide gives the sequence: set a string line at finished curb height, pour a 4,000 psi concrete footing, press each block into the wet concrete to the line with a joint between blocks, and mortar the joints once the concrete has set. The Borough of Beach Haven, New Jersey, writes the same 4,000 psi minimum into its code for block curbing. The concrete wrapping the bottom and back of each block, called the haunch, is the edge restraint that keeps the edge from spreading under wheel loads; industry guidance says cut stone edging generally runs the depth of the base, on compacted aggregate or concrete backfill. An apron is the same parts laid flat: blocks bedded in mortar on a concrete slab over a compacted base.
Edging on your side of the property line is private work; anything between the property line and the street is in the public right-of-way and needs the road owner's permit. On a Town street that is the Superintendent of Highways under Town Code Section 245-15, with a $300 minimum deposit under Section 245-16C, plus 10% of estimated work above $300, and a certificate of insurance naming the Town under Section 245-19. Work must start within 30 days, and the Town will not permit an opening in a road it resurfaced within the prior three calendar years, or five for a new or rebuilt road. In the Village of Head of the Harbor, block used for curbing must be approved by the Highway Department before it goes in, and the driveway and curb permit is valid 60 days.
Salt and freeze-thaw attack cement paste, so the parts of a block edge to watch are the joints and the bed, not the stone. Islip's normals show the local pressure: 98.3 nights a year at or below 32 degrees F, but only 16.4 days when the high stays at or below freezing, which leaves about 82 days a year that freeze at night and thaw by day. Mortar and haunch concrete are still cement products, so the deicer rules for concrete apply to them: never ammonium sulfate, ammonium nitrate or magnesium-based salts. Repointing open joints before winter keeps water out of the bed, where freezing does its damage.
For a useful estimate, measure the run in linear feet for edging, or the apron's length and its width at the curb and at the property line, and note the road name at the curb, since the road owner sets the permit. Settle the color early: a Kings Park mason supply yard lists regular block in gray, pink and yellow, and jumbo in buff, charcoal, gray, pink and yellow. If the driveway is due for replacement too, plan the edge with the new concrete driveway so the block goes in with the pour rather than being cut in afterward. Photos of loose or chipped blocks, and of the joint where the apron meets the road, let the estimate separate a reset from a rebuild. The quote form takes both.

When Belgian Block Is the Right Call, or an Old Edge Needs Resetting
Block earns its cost in a few specific situations, and an existing block edge shows when it needs work long before it falls apart. Look at the driveway edge, the apron where it meets the road, and the joints between blocks. These are the conditions that point to new block, or to lifting and resetting what is already there.
- The asphalt edge of the driveway is crumbling into the lawn where tires ride off the pavement, and nothing solid holds the edge in line.
- A concrete apron at the street has scaled or broken for the second time, and you want a surface at the curb with no cement paste to flake.
- Blocks in an existing curb rock underfoot, lean out of line or sit higher than their neighbors, which points to a cracked haunch or one that was never poured.
- Mortar joints between blocks have cracked or washed out, and sand, grass or ice is working into the gaps and pushing blocks apart each winter.
- Blocks at the street end of the apron are chipped, shoved back or missing after a plow pass, often where they stood above the road edge.
- Water stands along a block border after rain instead of running off, a sign the edge has settled or the base under it was never compacted.
A few loose blocks in a sound run are a reset: lift them, clean off the old mortar, bed them in fresh concrete to the line and repoint. Long runs that lean together mean the haunch failed and the edge needs rebuilding. If the loose curb is the Town's street curb rather than your driveway edge, the Town's FAQ says your only step is a Notice of Defect at the Town Clerk's office.
Jumbo vs Regular Block: Sizes, Weights and Counts per Foot
Long Island yards stock block in two main sizes, jumbo and regular. Jumbo block runs about 4 by 7 by 10 inches; one importer's spec sheet puts it at 26 pounds in gray, pink or buff and 33 pounds in black, and a Kings Park yard sells it 100 to a pallet. Regular block, also sold as regulation, is about 5 by 5 by 9 inches, 19 pounds in the lighter colors and 23 in black, sold 140 to a pallet at the same yard. Sizes drift by quarry and seller: another Long Island yard lists its jumbo at 4 by 8 by 10, as does one supplier's estimating table. Long Island yards also spell it Belgium block.
That table gives edging counts per linear foot of 1.5 jumbo or 1.33 regular blocks with a 1-inch joint, rising to 1.7 and 1.5 with no joint, and paving counts of 2.1 jumbo or 3.2 regular blocks per square foot laid flat. Its formula converts the count to tons at about 68 jumbo or 100 regular blocks per ton, the weight your delivery and lawn staging have to handle. Which size suits a curb depends on the reveal, the height of stone left showing above the pavement, and on how deep the haunch can go. Either way, the estimate should name the block size, count, joint width and the concrete under it in writing.
Setting Block in a Concrete Haunch: Mortar, Drainage and the Street Edge
The haunch carries the wheel load and the frost, so it deserves the same mix discipline as a driveway slab. All of New York sits in the severe weathering category on the state code's weathering map, and ready-mix guidance for exterior concrete exposed to deicers calls for 4,000 psi with about 6 percent total air. Ask what mix the haunch gets. Supplier guides set each block into the wet footing to a string line, leave a joint, and mortar the joints only after the concrete has set, so joint mortar is a separate visit.
For mortar in paving, the Brick Industry Association's selection guide recommends Type M for most exterior paving and advises the lowest strength that meets the job, since stronger is not necessarily better. Drainage belongs in the plan too: the Town of Haverstraw, in Rockland County, requires 4-inch perforated pipe in 3/4-inch stone or washed gravel under its granite block street curbs. At the street end, the Town of Smithtown's subdivision spec sets a one-inch step at the curb cut face, and a block set higher than its line gives a plow blade something to catch. Where block meets a poured sidewalk or slab, an isolation joint lets each piece move on its own; the NRMCA lists driveways against sidewalks among the places that need one.
Town, County, State or Village: Who Approves Block at the Curb
Smithtown's street standards in Town Code Chapter 248 name three curb types for subdivision streets in Section 248-37C: battered concrete, battered reveal concrete and cobblestone curb, with integral concrete curb and gutter wherever the grade exceeds 4%. Section 248-37E sets aprons at least 10 feet wide at the curb face and 7 feet at the property line, built to the same specification as the street paving or equal. Whether block counts as equal on your street is settled with the Highway Department at permit time. Next door, the Town of Huntington's Highway Office requires a hold harmless for anything other than concrete or asphalt, block and pavers included.
On a Suffolk County route, such as Harned Road and Indian Head Road (County Route 14) or Townline Road (County Route 76), the county's Non-Utility Highway Work Permit applies, with work built to county requirements and the latest NYSDOT standards. On a state route such as Route 25, 25A or 347, 17 NYCRR Section 125.9 sets the minimum driveway material within 10 feet of the travel lane as 1 1/2 inches of asphalt or 4 1/2 inches of cement concrete on a six-inch gravel base, so a block apron there needs NYSDOT's sign-off first. The villages add limits of their own: Head of the Harbor allows one curb cut per lot, no wider than 22 feet, and the Village of the Branch builds curbs 18 inches deep and at least 6 inches thick on residential streets.
Belgian Block Apron, Poured Concrete Apron, or a Block Border on Concrete?
The strip between the street and your property line can be all granite, all concrete, or concrete framed in granite. The choice turns on budget per square foot, the road owner's rules, and how the apron should look against the rest of the drive. The ranges below are national published figures, not Long Island prices.
Full Belgian block apron
Granite laid flat across the whole right-of-way strip, bedded in mortar on a concrete base and framed by a block curb. There is no concrete surface at the street to scale, and a damaged block can be cut out and reset without a new pour. It costs the most: the nearest published proxy, a national cobblestone driveway range, runs $18 to $50 per square foot. On a state route, the 10-foot rule names only asphalt or cement concrete.
Poured concrete apron
The Town's subdivision spec builds aprons to the street paving standard, and where the sidewalk crosses, the walk is six inches thick instead of four. A national cost guide puts concrete aprons at $8 to $18 per square foot, the lowest of the three. The risk is the surface: without entrained air and a 4,000 psi mix, salt and freeze-thaw can scale the paste off. The concrete apron and sidewalk page covers the Town thickness rules and the mix in detail.
Block border on a concrete drive
A band of block along the driveway edges and across the street end, framing a poured apron. Edging runs $9 to $11 per foot in national guides, on top of the concrete, and gives the look without paving the whole strip in stone. Leave an isolation joint where block meets slab so the two move separately. If the look matters most, a stamped cobblestone pattern in the concrete itself runs about $14 per square foot in one national pattern table.
On a Town street with no village rules on top, all three go through the same highway work permit and the same $150 residential apron fee. Budget per square foot and the road owner settle most jobs: concrete where cost rules, a border where the look matters, and full block where you want no cement surface at the street.
Belgian Block Curbing and Aprons FAQs
Does the Town of Smithtown allow a Belgian block apron?
The Town's street standards do not rule it out. Section 248-37E asks for aprons built to the same specification as the street paving or equal, and Section 248-37C lists cobblestone curb among the approved curb types. Those are subdivision specs, so whether block counts as equal on your street is answered by the Highway Department when the $150 residential apron permit is filed. Inside a village, the village decides, and Head of the Harbor wants curbing block approved before installation.
How much does Belgian block edging cost per foot?
National cost guides put block driveway edging at $9 to $11 per foot, stone curbing at $12 to $40 per linear foot and up with labor, and granite curbing material alone at $11 to $16 per linear foot. No published survey gives a Long Island figure, and the yards that stock block quote it rather than posting prices. One guide's New York City driveway page, at $10 to $28 per square foot against $8 to $20 nationally, shows how New York prices can run above national ones.
Should Belgian block be set in sand or in concrete?
Both methods exist. Supplier guides describe block over a compacted aggregate base, set in sand or mortar, and a 2021 City of Portland report notes that its historic block streets were both sand-set and mortar-set. For a curb that takes tires and plows, the supplier method is a 4,000 psi concrete footing with each block pressed in to a string line and the joints mortared later. Brick industry paving guidance adds that mortar setting beds belong only on a concrete base.
Do I need a permit for Belgian block edging on my own property?
The Town code does not answer it directly. Chapter 112, the building code, lists no exemption for driveway work, and Section 154-15 exempts the digging for a driveway, wall or sidewalk from the separate regrading permit, so ask the Building Department before work starts. Edging past the property line, in the right-of-way, needs the Highway Department permit. Head of the Harbor and Nissequogue both list driveways as work that needs a village permit.
Will a snowplow damage a Belgian block apron?
It can, at the street edge. Islip averages 31.8 inches of snow a year and 7.9 days with an inch or more, and each plowable storm runs a blade along the curb line. Blocks bedded in concrete and set to the line give a blade less to catch than loose blocks standing proud. The Borough of Beach Haven, New Jersey, makes owners waive claims for snow removal damage to the block, so ask the road owner about liability before the apron goes in.
