We have Unilock pavers around our in ground swimming pool. I’m
sure there are others who have pavers. How do you keep the weeds
from sprouting between the pavers? Tried an area with the weed
mat or newspaper, after a season (upstate NY) it looks the same
as the other areas. I use stone dust in the joints. I heard of
the chemical (weed stop) sand mix. Haven’t located any around
here. I hear its very expense, and wears away. I hate to use a
chemical (ie: roundup) because of it getting into the pool
water. Tried the weed torch to burn them, PITA. Does anyone
have a good solution to weeds and pavers?
A chemical but it will kill everything and anything. Be careful of wanted roots
may be near or under the weeds.
Ortho® GroundClear® Complete Vegetation Killer Concentrate
* Kills weeds and prevents new growth for up to 1 year
* Eliminates unwanted vegetation from driveways, walkways, patios, fence
rows and other areas
Actually, it's very different than Roundup. While Roundup also kills
just about everything, you can safely replant a week later. The above
type product not only kills, but keeps anything from germinating for 6
months to a year. It's designed for driveways, walkways, etc.
We had a contractor that was going to put a polymer type grount to fill in
the cracks....never got it done but sounded like a good solution that would
Thanks FDR. polymer grout...? Interesting! Seems, like it could
be a pain to install. If it installs like ceramic tile, you
can’t rub off the haze on pavers…
I wonder if polymer would prevent the natural drainage that is
needed around a pool.
FDR, What did you use for grout? Have any problems?
Triox works better. Sterilizes the soil. Nothing can germinate...even if
you plant something in it.
Ortho makes both products. I guess one saves a nickel but may work just
as well. I go for the sure kill myself. No stragglers.
Actually, we use a mineral cartridge at the pool pump for desanitizing. It
only requires a 1ppm chlorine residual in the pool so it never smells of
Why are you intentionally being an ass in your responses?
Sorry if this is a duplicate, I never saw my earlier reply show up.
Start by washing out as much of the stone dust as you can. Stone dust
is no good for interlocking paver joints. (I hope for your patio's sake
your setting bed is not stone dust as well.)
Let the area dry out thoroughly.
Invest in some polymeric joint sand (NOT grout), it should be available
from most resellers of concrete pavers. Follow installation instructions
carefully & completely.
The brand we sell here in Maryland can be seen here:
This product should eliminate virtually all your weed problems, and also
stop ants from tunneling through the joints & making piles of powder on
I set 500 sf of pavers 2 years ago. DW would only agree to pavers if I
promised that no weeds would grow in between them. I used a product called
Surebond. So far not a single weed has appeared. It's not cheap but it
works! I am not affiliated with the company - just a very satisfied
A friend of mine installed pavers using sand in the joints for a year or two
until he was sure there would be no settling, then he (a) pressure washed
them to wash out some of the sand, (b) sprinkled grout over the pavers and
used a broom to sweep it off the pavers and into the joints, and (c) gave it
a light sprinkling of water. It looks great, nothing grows in the cracks,
and it's really solid -- Regards --
