7 Reasons Why More Homeowners Are Choosing Polymeric Sand As Their Permanent Joint Filler Solution
(No Maintenance Required)
One application. Lasts for years.
Fix Fails
Sand washes out every season and cement cracks in the winter. They seem like the obvious fix but they were never built to hold. Polymeric sand was engineered to be the last solution you ever need — put it down once and it holds for years.
Ant Proof
Open joints are an open invitation for weeds to root and ants to tunnel in. Once the polymeric sand hardens, every joint is fully sealed. Weeds have no entry point and ants have nowhere to build. No gap. No weeds. No ants. It really is that simple.
Start by cleaning out your joints with a screwdriver or putty knife. Then pour the sand over the surface, brush it into every gap and soak it with your garden hose. — strong enough to outlast multiple winters but flexible enough to move with the ground without ever cracking. Do it once and it holds for years.
Flexibility
Once the polymeric sand sets, it bonds permanently into your joints. Unlike regular sand or cement, it uses a water-activated polymer that locks every grain together It hardens on its own in 3 hours and the job is done.
Wash Safe
Most joint fillers wash straight out the moment you pressure wash your surface. Which means every time you clean it, you're also destroying it. Polymeric sand locks deep inside the joint so even a pressure washer can't damage it. Clean your surface as hard as you want — the filler stays put.
Required
Sand is a seasonal chore. Cement eventually needs to be redone. Polymeric sand is neither — once it's in, your job is done. No topping up, no checking, no calling anyone. Just a clean sealed surface for the next decade.

What Our Customers Say
"Did my whole driveway two years ago and haven't touched it since. No weeds or cracks so far and it looks exactly the same as the day I put it in. First home project I've done that actually stayed done."
— Tom S., Verified Buyer
"I was skeptical because I'd tried sand twice before and it always came back. Did this one afternoon and that was it. Two seasons later and there's nothing to fix."
— Mike R., Verified Buyer
"I pressure wash my patio every summer and used to dread it because the sand always washed out. Used Permomix last spring and pressure washed it this year — joints are still perfect."
