The Ultimate Guide to Cambridge Pavers Joint Sand: Why Your Choice Between Polymeric and Regular Sand Can Make or Break Your Project

When it comes to completing your Cambridge Paver installation, the type of joint sand you choose is more than just a finishing touch—it’s a critical decision that affects the longevity, appearance, and maintenance requirements of your entire hardscape project. Understanding the performance differences between polymeric and regular sand can save you thousands in future repairs and countless hours of maintenance.

What Makes Joint Sand So Important?

Filling the joints of the pavers contributes to the vertical interlock that is achieved by interlocking pavement, which adds to the strength of the overall project. Without this material, the interlock would move around under the pressure of a dynamic load on the surface of the pavement. This structural component is essential for maintaining the integrity of your Cambridge Paver installation over time.

Regular Sand: The Traditional Approach

Regular dry joint sand is a natural product known as “all-purpose sand” or “leveling sand.” It is not the same as play sand, beach sand, or masonry sand—those types are not strong enough. Regular dry sand is fine-graded sand with some slightly larger granules in it. It is loose, flexible, and does not include bonding agents in the sand.

The main advantages of regular sand include its affordability and ease of installation. You can find it anywhere, costing $5 to $20 per 50-pound bag. Regular dry sand is the easiest to install. You dump the sand into the joints and sweep it with a broom.

However, regular sand has significant limitations. Regular dry sand in your paver joints will not prevent pests like weeds and bugs. In the PNW, it’s common to see weeds or ant hills popping up in areas through paver joints. Additionally, it will washout over time and will be subject to weed growth more so than polymeric sand.

Polymeric Sand: The Superior Solution

Polymeric jointing sand is not a natural product but a mixture of man-made and natural components. The fine particles of sand in joint sand have bonding agents such as silica. It seems similar to regular dry sand when it is dry, but when it is wet, the bonding agents activate and form a hard compound.

The performance advantages of polymeric sand are substantial. When appropriately applied, polymeric sand can last up to 10 years. But a typical span is three to five years, depending on the environment. Since it becomes rigid once dry, it doesn’t move around like regular dry sand.

Key Performance Comparisons

Pest and Weed Control

Polymeric sand, on the other hand, is known for controlling weeds and insects. It dries hard, and pests cannot get through without a crack. This creates a significant maintenance advantage for homeowners who want to keep their Cambridge Paver installations looking pristine.

Durability and Longevity

Regular sand will need a touch-up every couple of years, while touch-ups for polymeric sand would only be once every decade. More durable and resistant to erosion than conventional jointing products, polymeric sand significantly increases the life expectancy of any installation. In addition, joints obtained through the use of this material do not crumble, nor do they decompose.

Installation Complexity

While both materials are relatively straightforward to install, regarding the installation of Regular sand vs. Polymeric Sand, both materials are nearly the same. However, the polymeric sand application process could lead to more room for error. Polymeric sand is not technically hard to apply to your pavers, but it is possible to damage them. To install, pour the sand in the joints, sweep it in with a broom, activate it with water, and spray away any remaining dust or sand. This is the tricky part—if you don’t blow or rinse off your pavers, you can end up with a film of sand all over your pavers. You also must install polymeric sand on a warm and dry day during a week when temperatures do not dip below freezing.

Cost Analysis

Polymeric sand is also easy to find but will cost you more—anywhere from $20 to $90 per 50-pound bag. However, you should think carefully about the long-term benefits; polymeric sand may cost more initially but add up to much less over the years.

Expert Recommendations for Cambridge Pavers

For Cambridge Paver projects, professional installers consistently recommend polymeric sand for its superior performance characteristics. Installers prefer polymeric sand as it adheres best to the pavers and offers durable and even joints between them. The enhanced bonding properties work particularly well with Cambridge’s precision-manufactured pavers.

Making the Right Choice for Your Project

Polymeric sand is the more reliable and durable option for filling in the paver gaps. It outperforms regular sand when a homeowner is looking to lock the paver joints properly and wants a steady and stable path. While the initial investment is higher, the long-term benefits of reduced maintenance, superior weed and pest control, and enhanced structural integrity make polymeric sand the clear winner for most Cambridge Paver installations.

The choice between polymeric and regular sand ultimately depends on your project’s specific requirements, budget constraints, and long-term maintenance preferences. However, for Cambridge Pavers—known for their premium quality and durability—using polymeric sand ensures that your joint filling matches the quality of your investment in these superior paving stones.
