Preventing Weeds In Brick Pavers


I have a customer that wants to know if we are going to do something to prevent weeds from growing in between the bricks in a brick paver sidewalk.

This is for a new paver sidewalk, it's my first paver job.

Do you know of anything that will work?

Re: Preventing Weeds In Brick Pavers


you could try using polymeric sand, i think it has an additive to harden it to make it more difficult for the weeds to grow

I'm going to try a white vinegar and water solution on my crushed limestone drive.

The polymeric sand helps.
Give them a gallon of Round-Up
as a lovely parting gift.

Around here (ag country) you can buy generic, concentrate roundup for $16/gallon. That gallon will last them 5 years, spraying 3-4 times/summer. Can't think of anything any cheaper/easier than that.

I have seen several garden chemicals etch concrete. I can't remember if Roundup was one of these.

Don't waste your time or money.
Didn't work worth a darn on Calif. weeds.

Roundup is an acid, so that could be a possibility.

Most states require certification to apply pesticides for a customer. Yes, even for "stuff anyone can buy at Lowe's." Hire someone who is, or leave it alone.


Your profile lists you as a roofer, so I reckon you were unaware of this. That's OK, many landscapers are unaware of it too, and many more ignore it, and apply illegally.

pesticides kill bugs, herbicides kill plants. But you sounded like you knew what you were talking about.

Most guys around here put down a geotextile fabric first before pavers and base. It does a really good job fighting against weeds.

No one said anything about applying.
The weeds won't show up until
the OP is gone.
Please explain why you would
use pesticide on weeds anyway?

For sure, the combination of polymeric sand and geotextile fabric under the base work well.

Just for future reference when there are grass/weeds that you want to get rid of inexpensively, a mix of boiling water and a good amount of salt works quite well, and very effective for a quite a while. Non-toxic too. I put it on my drive in the springtime and generally don't have to reapply the rest of the year. Doesn't take a whole lot, but just pour enough of it on to "cook" the roots of the plant.

I was wondering...maybe the weed seeds are landing on top of the pavers and grow from there?

They sure will if there is suitable material for them to grow in. Some places weeds just thrive more than others, like my garden for instance!

Re: Preventing Weeds In Brick Pavers


Air-borne weed seeds are probably the most common problem for an established patio.

The joints are usually lower and seeds collect are washed into them. The surface shedding of water from the concrete pavers also collects in the joints and provides a source of moisture. Weeds can grow anywhere even if there is a "weed barrier" below.

Tress can grow in rock formations and create new cracks/joints, so why do people think that some short lived additive to the joint sand would really have much effect.

Boadleaf weeds are a minor short term problem than can easily be solved by the same "Weed-Be-Gone, etc. that is commonly used on lawns. For grasses, a light application of Round-Up" after germination and sprouting will be absorbed and kill to the roots. I used a squirt bottle once a year or so is usually adequate for patios, walkways and driveways.

For real paving surfaces (10 to 50 acres) polymeric sand is never used because of the cost, life and ineffectiveness over time.
