Hardscape material problems often get blamed on the pavers when the real issue is the sand, the base underneath, drainage, missing edge restraint, or a product that was never suited to the application. Identifying the actual cause is the first step toward correcting it.
Ocean County projects see sandy soils, coastal weather, and regular freeze-thaw cycles. Those conditions expose weaknesses in joint sand, base layers, and paver selection faster than in milder climates.
Cedar Bridge Landscape Supply in Barnegat stocks the Cambridge pavers, concrete sand, and bulk aggregates that address the most common material-related issues.
Common Paver Problems and Solutions Tied to Joint Sand
When Joint Sand Washes Out or Fails
Joint sand that washes out leaves gaps between units. Water and debris enter those gaps, and the surface can shift under foot traffic. Regular sand is more prone to this on slopes or in high-rainfall areas. Polymeric sand is designed to resist washout once activated, but it still requires proper joint width and a stable base underneath.
If joints are open or the sand has failed, the material itself may need replacement. Concrete sand is the typical bedding layer under pavers; joint sand is a separate product. Product details for concrete sand for paver bedding are available on the site.
The comparison of concrete sand vs. mason sand covers the differences that matter for bedding versus joint applications.
Base Layer Problems That Cause Settling and Shifting
Signs of an Inadequate Base
Low spots, rocking units, or areas that sink under furniture or foot traffic usually point to the base rather than the pavers themselves.
Angular crushed stone locks together when compacted and distributes weight.
A base that is too thin, poorly compacted, or made with rounded material is more likely to settle, especially on sandy Ocean County soils. Bulk crushed stone and aggregate options for structural layers are stocked by the yard. Review them on the bulk stone, sand, and base materials. The paver base essentials guide covers how these layers perform in local conditions.
ICPI standards address aggregate specifications for interlocking systems.
Drainage and Edge Restraint Issues
Water and Movement Problems
Standing water or units that creep outward over time often involve drainage or missing edge restraint. Water that cannot move away from the surface saturates the base and accelerates settling. Without edge restraint, the units can spread under load, opening joints and reducing interlock.
Open-graded or clean crushed stone helps water move through the base. Edge restraint systems keep the perimeter locked. Both are part of a stable installation. Confirming the correct materials with the yard team before ordering reduces the chance of repeating the same problem.
Paver Selection Problems and Solutions
When the Wrong Product Was Used
Some failures come from using a paver that was never suited to the application.
Thinner units or styles not rated for vehicular traffic will crack or shift under cars. Softer natural stones can be worn faster under heavy foot traffic in a coastal climate. Cambridge interlocking pavers are manufactured to consistent thickness and are available in options suited to residential patios, walkways, and other hardscape uses.
As an authorized Cambridge dealer, the Barnegat yard stocks design kits and slab sizes. Compare options on the Cambridge pavers and hardscape materials. Matching the product to the expected use is one of the more practical ways to avoid future material problems.
How to Identify the Root Cause
Start with what you can see. Open joints and missing sand points to joint material. Low spots or rocking units usually involve the base. Water that sits or runs in the wrong direction suggests drainage. Units that have moved outward indicate edge restraint.
Cracked or worn units may mean the wrong product was chosen for the traffic.
A full hardscape supply checklist covers the surface, base, bedding, edge, and joint materials typically needed. The hardscape supply checklist organizes those categories.
Bringing photos or a description of the problem to the yard helps the team point to the right materials for the repair.
Get the Right Materials for the Repair
Once you know whether the issue is joint sand, the base, drainage, or the pavers themselves, the next step is getting the correct materials.
Look through the hardscaping and bulk materials pages for Cambridge pavers, concrete sand, and crushed stone options that match the problem. Stop by our yard at 309 Route 72 in Barnegat to see the materials and describe what you’re seeing on the project.
The team can point you to the right sand, aggregate, or paver without guessing. If you already know what needs replacing, request a quote, and they’ll confirm stock and delivery for your Ocean County job.

Frequently Asked Questions
Why do pavers settle or shift?
Settling is usually caused by an inadequate or poorly compacted base, especially on sandy soils. Joint sand failure or missing edge restraint can also allow movement. The base and bedding materials are the first place to check.
What sand should be used under and between the pavers?
Concrete sand is commonly used as the bedding layer under pavers. Joint sand—sometimes polymeric—fills the gaps after the units are set. The two products serve different purposes.
Can the wrong paver cause problems later?
Yes. Units that are too thin for the expected traffic or not suited to coastal conditions can crack or wear faster. Cambridge interlocking pavers are available in consistent thicknesses suited to residential hardscape.
Where can I get the right materials for repair?
Cedar Bridge Landscape Supply in Barnegat stocks Cambridge pavers, concrete sand, and bulk aggregates for base layers. Stop by or request a quote with a description of the issue.
