For a New Jersey developer or property manager, a new construction project is a high-stakes investment. While you might worry about timeline delays or the cost of steel, the most financially devastating problems are often silent and buried underground. Site work failures can turn a multi-million dollar asset into a permanent liability.
These aren't minor issues; they are foundational flaws that can lead to safety hazards, compliance violations, and six-figure repair bills. Here are three of the most common construction problems in New Jersey and how to prevent them before the first shovel hits the ground.
1. Failure: Catastrophic Sub-Base Failure
What it looks like: You see it in the parking lot 2-3 years after the build. The asphalt begins to sink in long, straight lines where utility trenches were dug. Large, web-like "alligator cracking" appears in high-traffic areas. The pavement feels soft or spongy after a rainstorm.
Why it happens: This is almost never a "pavement" problem. It's a base problem. It occurs because the aggregate sub-base beneath the asphalt was not properly compacted, was installed with the wrong materials, or was laid on top of unstable, wet soil. In New Jersey, this is often rushed. Contractors fail to properly test soil density or don't use the right compaction equipment. The base shifts, and the flexible asphalt on top sinks and cracks.
How to prevent it: Your site work partner must have an engineer-led approach. This involves soil testing (proctor tests) to determine the optimal moisture content for compaction. It requires using the right equipment (like a vibratory roller) and installing the base in 4- to 6-inch "lifts," compacting each one individually to 95% density before adding the next.
2. Failure: Systemic Drainage & Water Pooling
What it looks like: Every time it rains, your new parking lot turns into a lake. Catch basins are overwhelmed, and water sheets across drive lanes, creating a hazard for pedestrians and vehicles. In winter, this water freezes into massive ice slicks, creating a huge liability. Worse, water pools directly against your building's foundation.
Why it happens: The project was improperly graded. Pavement is not flat; it must be installed with a precise "pitch" or "fall" (typically 1-2%) to channel water toward the drains. This failure means the contractor either didn't follow the engineering plan or didn't have one at all. They paved a flat surface that traps water instead of shedding it.
How to prevent it: This requires a site contractor who is an expert in both excavation and paving. They must use laser-guided grading equipment to ensure the sub-base has the perfect slope before the first "hot mix" truck arrives. The paving team must then lay the asphalt in a way that preserves this precise pitch, ensuring water is actively and efficiently moved to the stormwater system.
3. Failure: Rapid Concrete Spalling and Cracking
What it looks like: After just one or two winters, the concrete curbs are flaking and crumbling. The corners of your sidewalks are cracking, and the surface of your dumpster pad is flaking away, revealing the stone aggregate underneath.
Why it happens: This is called spalling. It's the direct result of the freeze-thaw cycle in New Jersey, and it's accelerated by low-quality work. Either the concrete mix was improper (too much water), it wasn't air-entrained (a process that adds microscopic air bubbles to let frozen water expand), or it was "finished" improperly by a crew that over-troweled the surface.
How to prevent it: You need a true concrete specialist. They must use the correct PSI-rated, air-entrained mix for the specific application (e.g., a dumpster pad needs a much stronger mix than a sidewalk). They must also know not to pour during the wrong weather and how to properly cure the concrete.
The single best prevention for all three of these issues is to avoid hiring piecemeal, low-bid subcontractors. The best construction companies in NJ partner with a single, expert-grade firm that manages all construction services, from the excavation to the concrete to the final layer of asphalt.
