If you do not want to use any products or chemicals, pressure washing is the best way to kill weeds between paving stones. Simply pull the weeds by hand, and then use a pressure washer around the paver stones to remove the roots.
Once your pavers are in place, fill the spaces between the stones with polymeric sand, which forms an effective barrier to weeds. 2.
In the old days, patio owners were removing old contaminated sands from cracks & sand between pavers in patio or bricks of brick patio. They used to fill up the crevices in stone pavers or brick patio with new or fresh sands between pavers. Unfortunately, it alleviated weed growth only for a limited period of seasons.
We recommend either purchasing a weed killing mix, or combining water, white vinegar and dish soap in a spray bottle. Once you have sprayed the weeds, wait until the mixture has killed them. Once the weeds are dead remove all the plant matter from the concrete joints.
The safest places to use vinegar weed killer are between concrete seams in sidewalks, mulch or gravel paths, and driveways. It's usually easy to spray the vinegar in these areas without getting it on other plants.
Is Roundup Safe to Use? According to the EPA, there are “no risks of concern to human health from current uses of glyphosate” if products are used as directed.
To stop weeds from growing between pavers, you first need to ensure proper installation, seal pavers, and stabilize the sand bedding. You can also halt weed growth by doing regular sweeping, torching, pressure washing, or pulling the roots.
It works because it has a high salt content that will suck the moisture out of the foliage and roots. Once this happens, your weeds will become dehydrated and die, so they can't grow back. When using this method, you need to be careful because baking soda won't prevent just your weeds.

It's time to ban it. Roundup's main ingredient is a probable human carcinogen, but it's almost impossible to avoid coming into contact with it. The EPA must ban it, unless and until independent research proves it safe.
The risks are much greater once it dries, and since it has a half-life of up to 197 days, the dangers of the dried chemicals becoming airborne, particularly on sports fields and in high-traffic areas, are significant.
Is Glyphosate Banned in the United States? Despite the IARC report's 2015 conclusion that glyphosate is a probable human carcinogen, the U.S. Environmental Protection Agency (EPA) has held that glyphosate poses no unreasonable risk to the environment or human health. But that classification could soon change.
Bricks. The acid content in vinegar is particularly good at breaking down the molecules in clay surfaces. Standard bricks are made mostly from clay, so exposure to undiluted vinegar will quickly result in discolouration and a sticky chemical byproduct coating your bricks.
Vinegar is not selective. Glyphosate, the ingredient in Roundup and other products, is translocated from the leaves to the roots of a weed. Vinegar is not translocated. It is true that 5% vinegar (acetic acid) will kill young, tender weeds but it does little damage to established weeds.
The Takeaway. To eradicate weeds effectively, the roots need to be killed, not just the top growth, which synthetic weed killers do successfully. The bottom line is that mixing vinegar with Epsom salts or table salt and liquid dish soap does not make a safe, effective weed killer.
