Question 1

Can damaged pavers from snow removal be individually replaced?

Accepted Answer

Yes, individual damaged pavers can absolutely be replaced — this is one of the key advantages of interlocking pavement over poured concrete. Unlike concrete slabs that crack permanently, damaged pavers can be lifted out and new ones installed without affecting the surrounding installation.

Snow removal damage typically affects pavers in predictable ways. Metal snow shovels, ice chippers, and snow blowers can chip paver edges, crack surfaces, or cause spalling (surface flaking). Salt and de-icin

Question 2

Should I hire a pro or DIY to fix a few sunken pavers on my patio?

Accepted Answer

For a small area of sunken pavers (10-20 pavers), this is one of the few interlock repairs that many homeowners can successfully DIY. However, the underlying cause of the sinking determines whether a DIY fix will be temporary or long-lasting.

What causes pavers to sink in Metro Vancouver is usually one of three issues: inadequate base compaction during original installation, water washing away bedding sand from underneath the pavers, or tree roots displacing the base material. If only a few pav

Question 3

Why is there white residue on my interlock pavers and how do I remove it?

Accepted Answer

The white residue on your interlock pavers is called efflorescence — a natural process where calcium carbonate leaches from the cement in concrete pavers and appears as a chalky white film on the surface. This is completely normal for new concrete pavers and typically fades on its own within 6-12 months through normal weathering and rain exposure.

What Causes Efflorescence

Efflorescence occurs when water moves through the concrete paver, dissolving calcium compounds from the cement, and then e

Question 4

How do you match replacement pavers to an older interlock installation?

Accepted Answer

Matching replacement pavers to an existing installation requires identifying the original manufacturer, product line, and colour — though perfect matches are often impossible for installations over 5-10 years old due to weathering and product discontinuation.

The most practical approach starts with identifying the original manufacturer and product specifications. Look for any remaining packaging, receipts, or installation documentation that lists the paver brand, style name, and colour. Common

Question 5

How do you fix edge pavers that are crumbling along the driveway border?

Accepted Answer

Crumbling edge pavers along a driveway border indicate missing or failed edge restraint, inadequate base support at the edges, or traffic loads exceeding the paver's capacity. This is a structural issue that requires removing the damaged pavers, rebuilding the edge support system, and installing proper edge restraints to prevent future failure.

The most common cause of crumbling driveway edges in Metro Vancouver is missing edge restraint. Pavers along unconfined edges spread laterally under veh

Question 6

Can you lift and relay pavers to fix a drainage problem?

Accepted Answer

Yes, existing pavers can be lifted and relaid to fix drainage problems, but success depends on the underlying cause and extent of the drainage issue. This approach works well for localized settling or minor grade corrections, but major drainage problems often require more extensive base reconstruction.

When Lifting and Relaying Works

If your drainage problem is caused by a few sunken pavers creating low spots where water pools, lifting and relaying is often an effective solution. This typicall

Question 7

How often should interlock pavers be re-sanded in the Vancouver climate?

Accepted Answer

Interlock pavers in Metro Vancouver should have their joint sand replenished every 3-5 years, compared to 5-8 years in drier climates. Vancouver's heavy rainfall (over 1,200mm annually) and persistent humidity accelerate joint sand erosion, making regular re-sanding one of the most important maintenance tasks for paver longevity.

Why Metro Vancouver Requires More Frequent Re-sanding

Vancouver's marine climate creates unique challenges for joint sand retention. The region receives approximately

Question 8

What do I do about ants pushing sand out between my pavers?

Accepted Answer

Ants excavating sand from paver joints is a common problem in Metro Vancouver, especially during the drier summer months when ant colonies are most active. The solution is switching to polymeric sand, which hardens when cured and creates a barrier ants cannot easily excavate through.

Ants are attracted to regular jointing sand because it's easy to dig through and provides ideal nesting material. They'll systematically remove sand from joints to create tunnels and chambers for their colonies, le

Question 9

How do you repair interlock pavers that have shifted or spread apart?

Accepted Answer

Repairing shifted or spread-apart interlock pavers requires lifting the affected pavers, correcting the underlying base issues, and reinstalling with proper edge restraints and joint sand. The repair approach depends on whether the shifting is localized (a few pavers) or widespread (indicating base or edge restraint failure).

Diagnosing the Problem First

Before starting repairs, identify why the pavers shifted. In Metro Vancouver's wet climate, the most common causes are inadequate edge restra

Question 10

Can a paver driveway be releveled without removing all the pavers?

Accepted Answer

Yes, a paver driveway can often be releveled without removing all the pavers, but this depends on the extent of settling and the underlying cause of the problem. For minor settling in isolated areas (typically 10-30% of the driveway surface), experienced contractors can lift and relay sections while leaving the stable areas intact.

Partial releveling works best when settling is localized — such as areas near the garage door where heavy vehicles repeatedly load the same spots, or sections where

Question 11

How do you fix weeds growing between interlock pavers?

Accepted Answer

Weeds growing between interlock pavers are primarily caused by deteriorated or missing joint sand, and the fix involves removing the weeds, addressing the underlying sand issue, and applying preventive treatments. In Metro Vancouver's moist climate, weed growth in paver joints is one of the most common maintenance challenges homeowners face.

The root cause of weeds in paver joints is almost always compromised joint sand. When the original sand between pavers washes out (common with standard mas

Question 12

What causes polymeric sand to wash out between pavers in Vancouver?

Accepted Answer

Polymeric sand washes out between pavers in Vancouver primarily due to improper activation during installation, choosing low-quality products that can't withstand the region's heavy rainfall, and the natural degradation that occurs faster in Metro Vancouver's persistently wet climate.

The most common cause is incorrect water activation during installation. Polymeric sand must be activated with a controlled mist of water — not flooded or soaked. Many installers either use too much water (which w

Question 13

Why are my interlock pavers sinking in certain spots?

Accepted Answer

Sinking pavers are almost always caused by inadequate base preparation or water infiltration that has compromised the foundation beneath your installation. In Metro Vancouver's wet climate, this is unfortunately one of the most common interlock problems, and it typically gets worse over time if not properly addressed.

Base Preparation Issues

The most likely culprit is insufficient base depth or poor compaction during the original installation. Residential patios and walkways require a minimum

Question 14

Can you replace a few broken pavers without redoing the whole area?

Accepted Answer

Yes, individual broken pavers can absolutely be replaced without redoing the entire installation. This is one of the major advantages of interlocking pavers over poured concrete — damaged units can be lifted out and replaced while leaving the surrounding pavers undisturbed.

The replacement process involves lifting the damaged paver and surrounding units, correcting any base issues, and reinstalling with a matching paver. Start by removing the polymeric sand from around the broken paver using a

Question 15

What's the cost to re-sand and re-seal an interlock driveway in Vancouver?

The cost varies significantly based on the repair approach required. Minor heaving affecting 50-100 square feet where roots haven't completely destroyed the base runs $1,500-$3,500. This involves lifting the affected pa

Question 17

Is it cheaper to repair or replace an old interlock driveway?

Accepted Answer

The decision between repairing or replacing an old interlock driveway depends on the extent of damage, but repair is typically 50-70% less expensive when the base is still sound. For most Metro Vancouver driveways showing settling, weed growth, or missing joint sand, repair runs $3,000-$8,000 compared to $12,000-$25,000 for complete replacement.

When Repair Makes Financial Sense

If your driveway has isolated sunken areas, widespread weed growth, faded pavers, or missing joint sand but the majo
