How to Stop Weeds in Block Paving: Expert Tips from Advance Driveway Solutions

Block paving brings style, durability, and curb appeal to your home’s exterior—but nothing spoils its neat appearance quite like weeds creeping through the joints. These unwanted guests can quickly turn a beautiful driveway or patio into a maintenance nightmare.

At Advance Driveway Solutions, we specialize in helping homeowners restore and protect their paving from common issues like weed growth. In this detailed guide, you’ll learn why weeds grow in block paving, how to remove them effectively, and—most importantly—how to prevent them from coming back.

Why Do Weeds Grow in Block Paving?

Contrary to popular belief, most weeds don’t grow up from underneath your block paving—they grow from above, when seeds settle and germinate in the gaps between blocks.

Common Causes of Weed Growth in Block Paving:

Wind-blown Seeds: Weeds such as dandelions, chickweed, and moss often arrive via wind and settle into the tiny cracks in your paving.
Organic Build-up: Dirt, dust, fallen leaves, and bird droppings collect in the joints over time, creating a fertile bed for weed seeds.
Moisture & Poor Drainage: Damp environments are ideal for weed growth. Block paving areas with poor drainage or shaded spots are especially vulnerable.
Lack of Maintenance: If block paving isn’t regularly cleaned or resealed, the gaps between blocks can become breeding grounds for weeds, moss, and algae.

How to Stop Weeds in Block Paving: Proven Methods

The best way to stop weeds in block paving is to prevent them from taking root in the first place. Here’s how:

1. Preventive Maintenance: The First Line of Defense

The best way to stop weeds in block paving is to prevent them from taking root in the first place. Here’s how:

Regular Sweeping

Sweep your paving at least once a week.

Use a stiff-bristled broom to remove dust, leaves, and seeds.
This reduces organic material buildup and prevents seeds from settling.

Power Washing (Jet Washing)

Power wash your paving every 6–12 months.
High-pressure water lifts out dirt, moss, and early weed growth from joints.
Be cautious not to disturb the sand between the blocks—resanding may be needed after washing.

Edge Control

Trim grass, plants, and hedges that grow near your block paving.
Weeds often start at the edges and migrate inward.

2. Weed Removal Techniques: Get Rid of What’s Already There

If you’re already seeing weeds, don’t worry. Here are safe and effective removal techniques:

Manual Weed Removal

Use a weeding knife or block paving scraper to extract weeds from the roots.
Ideal for light infestations or eco-conscious homeowners.
Best done after a rain when the ground is soft.

Natural Weed Killers

Boiling Water: A simple and effective method—just pour directly on the weed.
White Vinegar Spray: Mix 1 part vinegar with 1 part water, add a few drops of dish soap, and spray.
These methods are non-toxic and great for households with pets or children.

Chemical Weed Killers (Herbicides)

Use a glyphosate-based product for stubborn or widespread infestations.
Apply in dry weather when no rain is expected for 24 hours.
Be cautious around plants and follow all safety instructions.

3. Block the Growth: Long-Term Weed Prevention

Short-term fixes are great, but to truly stop weeds in block paving, you need to block their access and growth.

Use of Polymeric Sand

Unlike regular kiln-dried sand, polymeric sand contains binders that harden when wet.
Once installed, it creates a solid seal that blocks weed seeds and insects from penetrating the joints.
Great for patios, driveways, and paths with heavy foot or vehicle traffic.

Seal Your Block Paving

Paving sealers are liquid solutions applied to the surface and joints of the paving.
They create a protective barrier that:
- Prevents weed seeds from settling.
- Reduces water penetration.
- Enhances color and extends the life of the paving.
Reapply every 2–3 years for best results.

FAQs: Stopping Weeds in Block Paving

Q1: Will sealing block paving stop weeds permanently?
Sealing significantly reduces weed growth but may not completely eliminate it. It forms a barrier against moisture and seed germination—when combined with good maintenance, it offers near-complete protection.

Q2: Can weeds grow through polymeric sand?
Very rarely. Polymeric sand creates a tough joint that resists weed penetration. It’s far more effective than traditional jointing sand.

Q3: How often should I reseal my block paving?
Every 2–3 years, depending on usage, weather conditions, and sealer type.

Q4: Is pressure washing safe for block paving?
Yes—but it should be done with care. Too much pressure can dislodge jointing sand. Always follow up with re-sanding.
