A common question from homeowners is, "How do we stop weeds from growing between my pavers?" In 2025, keeping a weed-free patio or driveway is easier with proper installation and maintenance. Let's break down the myths and solutions.
Myth
A common objection to installing concrete pavers is that you will get weeds between the joints.
A common question from homeowners is, "How do we stop weeds from growing between my pavers?" In 2025, keeping a weed-free patio or driveway is easier with proper installation and maintenance. Let's break down the myths and solutions.
Myth Busting
You'll only get weeds when industry standards are not met both on the installation and maintenance side of concrete pavers.
Weeds do not grow from underneath the pavers unless the pavers are installed on the soil.
Weeds can grow on the surface of the joint if natural sand was used and if dirt is present. With a little bit of wind, weed seeds will blow into the joints, and with sun and water, they will root into these areas.
How to Stop Weeds
There are two stages where you can prevent weeds. They are during the installation and maintenance stages of concrete pavers.
Installation Stage:
When interlock pavers are installed, polymeric sand should be installed between the joints. It should be established according to manufacturer instructions.
Polymeric sand such as Alliance's Super Sand G2 or Techniseal's HP NextGel, is essentially glue and sand mixed to form a strong bond that is also flexible enough to float with the pavers during its freeze and thaw cycles. While flexible, polymeric sand when cured is rock hard to the touch and doesn't contain moisture or nutrients for weeds.
Maintenance Stage:
With any item ever created by man, there is inevitably maintenance. With concrete paver surfaces, three things need to be maintained over time.
Number One: Polymeric sand based on the micro-climate conditions, will need to be replaced when it no longer has its bonding strength. Many owners will opt for merely topping up the low joints with new polymeric sand. While this can work great most of the time, new sand will not bond with old sand, and eventually, the new sand will crack and pop out.
We often recommend a full replacement which consists of power washing the joint completing out (or as best as possible) and installing a new batch of polymeric sand. Not only will this keep weeds out indefinitely, but it will also bring back the interlocking structural strength that polymeric sand provides to the paver system. Without it, pavers will slide, rotate and shift with the freeze-thaw cycles and traffic.
Number Two: Although not a primary preventative for weeds or moss, cleaning and sealing your pavers every 2-4 years will keep them cleaned and protected from the elements. This will inevitably remove and prevent dirt and debris. It will also maintain the look and appearance of the pavers over their lifetime (remember, they will last a lifetime, backed by a lifetime manufacturer warranty from most manufacturers).
For cleaning products, Alliance's Paver Cleaners and Techniseal's Paver Cleaners are rated the best in the industry. They also have Alliance's Paver Sealers and Techniseal's Paver Sealers as well.
Number Three: As with any product, repairs will always be needed in some shape or form. The benefit to pavers over other paving surfaces is you will only need to repair the sections that need it rather than removing the entire surface.
We recommend paver lift & relays during a joint replacement or before cleaning and sealing.

FAQs
How to remove weeds between pavers?
To remove weeds between pavers, use boiling water, a vinegar solution, or a weed torch. Manual removal with a joint scraper is also effective.
How to prevent weeds from growing between pavers?
Prevent weeds by using polymeric sand in the joints, sealing the pavers, and regularly cleaning to remove dirt and debris where seeds can take root.
How to eliminate weeds between pavers?
Eliminate weeds by applying herbicides, using a pressure washer, or replacing the joint sand with polymeric sand to block future weed growth.
What is the difference between pavers and interlocks?
Pavers are a broad category of paving stones, while interlock pavers are specifically designed to fit together tightly, creating a stable and durable surface.
Are interlocking pavers cheaper than concrete?
Interlocking pavers have a higher upfront cost than concrete but offer better durability, flexibility, and easier repairs, making them more cost-effective long-term.
