Hardscape in Conshy That Lasts.
Most Conshy lots are on a slope, and most of the rowhouse and twin stock has stoops, sidewalks, and driveway aprons that have been through too many winters. NextGen rebuilds them right — deep footings, deep stone base, and drainage where it matters.

[ Why Conshohocken ]
Conshohocken is a borough of roughly 9,400 residents along the Schuylkill's western bank, with a housing stock dominated by brick rowhouses and Italianate townhomes from the early 1900s. Median construction year is 1958, but the Fayette Street corridor and older sections of Cedar Heights and Conshohocken South have homes dating to the 1880s–1910s. The concrete and masonry at those properties — stoops, sidewalk panels, driveway aprons, and rear patio slabs — has been through the full count of Pennsylvania winters. Most of it shows it.
The riverfront redevelopment boom in Conshohocken — new apartment buildings, office campuses, and retail along the Schuylkill — has raised property values throughout the borough and increased homeowner investment appetite for exterior upgrades. For residential properties on Borough Center's Fayette Street corridor and Spring Mill, that often means a new patio replacing a decades-old cracked slab, a stoop rebuild on a brick twin, or a driveway expansion to accommodate a second vehicle.
Tight lot lines on most residential streets in Conshohocken mean retaining walls and graded rear patios are frequent project types. Many properties on hillside streets need a retaining wall to create a usable level yard behind a home that otherwise slopes steeply from the foundation to the property line. NextGen installs segmental block retaining walls with proper drainage columns — 12 inches of clean stone behind the wall face with a perforated drain at the base — on every hillside project in the borough.
Conshohocken Borough's code enforcement is active. The borough requires a permit for all sidewalk, curb, and driveway work. Sidewalks must be a minimum 5 feet wide concrete or borough-approved material. All contractors performing paving or concrete work for property owners must hold a Borough of Conshohocken contractor license. New slabs require proper jointing at 5-foot intervals and curing per borough construction standards. NextGen is licensed with the borough, pulls every required permit, and meets these standards without exception.
Frost heave in Conshohocken is driven by 20 to 30 freeze-thaw events per winter. Brick rowhouse stoops that heave away from the foundation every spring and settle back unevenly are a visual constant in the borough's older sections. The root cause is always the same: original stoops were poured without footings extending below the frost line, so the stoop structure moves with the frost while the house foundation does not. NextGen rebuilds stoops with footings at 36 inches below grade — the PA frost depth — so the stoop is anchored below the zone of frost action.
Word travels fast in Conshohocken. MoreThanTheCurve.com covers the borough extensively, and neighbor referrals drive most local contractor selection. Visible exterior work on a rowhouse or twin is seen by everyone on the block. NextGen's commitment to clean jobsites — debris removed daily, forms stripped and hauled same day as pour, no concrete splatter on adjacent surfaces — is part of the job, not an afterthought.
"Most Conshy lots are on a slope. That means a wall, somewhere — and behind every wall we build, there's drainage."

[ Climate Panel / Freeze-Thaw History ]
Why we use a freeze-resistant concrete mix.
Greater Philadelphia averages 25 freeze-thaw cycles per winter. Each cycle drives water into tiny pores in the concrete, where it freezes and expands ~9%. Without 5–7% entrained air, that pressure flakes the surface apart within 5 years. (Severe freeze-thaw zone per building code: ACI F2.)

Conshohocken FAQ
Common questions about concrete in Conshohocken.
Q.01
Do I need a permit to replace my front stoop in Conshohocken?
In Conshohocken Borough, all sidewalk and structural concrete work requires a permit from the Code Enforcement / Licenses and Inspections Department. Replacing a front stoop — even at the same footprint — typically triggers a permit requirement because it involves structural concrete. All contractors performing this work must also hold a Borough of Conshohocken contractor license. NextGen Masonry is licensed with the borough and handles permit research and filing as part of every Conshohocken project.
Q.02
My Conshohocken rowhouse stoop lifts away from the house every spring. What is happening?
This is frost heave — one of the most common failure modes in Conshohocken's pre-1940 rowhouse stock. The original stoop was poured without footings below the frost line, so the stoop rides with the freezing and thawing soil each winter while the house foundation (anchored in soil that stays unfrozen) doesn't move. The gap that opens between stoop and foundation each spring is the difference between what froze and what didn't. The only permanent fix is to rebuild the stoop on footings 36 in. below grade — below the PA frost line — so the stoop is anchored in soil that stays unfrozen all winter.
Q.03
Can NextGen build a rear patio on a sloped Conshohocken lot?
Yes. Many lots on Conshohocken's hillside streets slope steeply from the house toward the property line. Creating a usable level patio area requires either cutting into the slope (and managing the removed grade with a retaining wall) or building a raised slab patio over the grade change. NextGen assesses the specific site geometry on the estimate visit and proposes the most structurally appropriate solution. Hillside patio projects in Conshohocken almost always include a segmental retaining wall component.
Q.04
What is the minimum width for a replacement sidewalk in Conshohocken?
Conshohocken Borough requires replacement sidewalks to be a minimum of 5 feet wide and constructed of concrete or other borough-approved material. New slabs must have proper jointing at 5-foot intervals and be cured per borough standards. The borough's code enforcement is active — a replacement sidewalk that does not meet these standards will not pass inspection and will need to be redone. NextGen Masonry builds to borough specification on every Conshohocken sidewalk project.
Q.05
How long does a concrete project take in Conshohocken's tight lot conditions?
Most Conshohocken residential concrete projects run two to three days. Day one is demolition and base prep, day two is pour and initial finish, day three is saw-cutting, curing compound touch-up, and debris removal. The tight lot lines and rowhouse density mean staging is planned on the estimate visit — where the pump truck or chute truck will position, where demolition debris stages before pickup, and whether any temporary lane use needs to be coordinated with the borough. We do not start a project without a clear logistics plan for the specific block.
