Keansburg is a small, densely built borough on the Raritan Bay, with a beachfront, an amusement area and blocks of modest homes. Many houses started out as summer bungalows and were later converted to year-round living. Lots are small and the land is low, close to sea level in many places. Water is the main force acting on masonry here, from storm surge and high groundwater to everyday rain with nowhere to go.

Concrete that has heaved, cracked or sunk

Walkways, stoops and patios on low ground take a beating. Water under slabs washes out the base, freezing water lifts them, and salt eats the surface. Not every cracked slab needs to go. Our concrete repair and resurfacing can restore a slab that is still sound underneath. When it has sunk or tilted toward the house, we replace it on a new compacted base with proper pitch.

Small steps, built right

Many Keansburg homes have short front stoops of two or three steps. Small steps still need a real footing, and in wet ground that matters more. We rebuild concrete steps and porch slabs with good drainage at the base, and we can face them in block or brick. Railings are anchored with salt exposure in mind.

Damp foundations and crawl spaces

With water close to the surface, many homes deal with damp crawl spaces, wet basement corners and efflorescence on block walls. Our basement waterproofing work starts outside with grading, downspouts and crack sealing, then moves to interior drainage when needed.

Practical tips for bayfront homes

  • Extend downspouts well away from the foundation.
  • Keep grades sloping out, even on a small lot.
  • Seal small cracks early before water and frost widen them.
  • Rinse salt off steps and railings after storms.
  • Check flood zone rules before adding new hardscape.

FAQ

Keansburg, NJ FAQs

Can’t find your answer? Call us at (973) 874-8169.

Can my cracked walkway be repaired or does it need replacing?

If the slab is still level and mostly in one piece, crack repair or resurfacing can extend its life. If it has sunk, tilted toward the house or broken into chunks, replacement on a new base is the better value.

Water comes into our crawl space after storms. What can be done?

We start by looking at grading, gutters and where water collects outside. Sealing cracks and improving drainage often helps a lot. For heavier problems, we discuss waterproofing systems suited to a high water table.

Are there flood zone rules for steps and walks in Keansburg?

Many lots in town are in a flood zone, which can affect fill, grading and new structures. We check with the borough before work begins and handle permits when they apply.
