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

Question

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

Answer from Interlock IQ

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 narrow chisel or oscillating multi-tool. Then lift the damaged paver with flat pry bars or specialized paver pullers — you may need to remove 2-3 adjacent pavers to access the broken one if it's in the middle of the installation. Once the broken paver is out, inspect the bedding sand beneath for low spots or contamination and add or remove sand as needed to restore proper level and grade.

Finding matching pavers is usually straightforward if the installation is less than 10 years old. Most major paver manufacturers (Expocrete, Barkman, Belgard, Techo-Bloc, Mutual Materials) maintain consistent product lines, and local suppliers typically stock popular colours and styles. Bring a sample of your existing paver to the supplier for the best colour match — concrete pavers can fade slightly over time, so a brand-new paver may appear slightly darker than your weathered installation initially. The colour difference typically evens out within 6-12 months of weathering. For installations over 15 years old, you may need to check with specialty suppliers or architectural salvage yards, or consider replacing a small section with a complementary accent colour.

Metro Vancouver's wet climate makes proper joint sand replacement critical after paver replacement. Once the new paver is installed and leveled, sweep polymeric sand into all the joints around the repair area and activate it according to manufacturer instructions. Standard play sand will wash out during the first heavy rainfall, leaving the repaired area vulnerable to shifting. The persistent moisture in our climate means that any gaps in the joint sand become pathways for moss and weed growth within weeks.

Common causes of paver breakage in Metro Vancouver include tree root pressure, settling from inadequate base preparation, and impact damage from heavy objects. If you're replacing pavers due to root heave, address the root issue with root barriers or consider that periodic maintenance may be needed. If pavers are breaking due to settling or base failure, the underlying problem needs correction — simply replacing the broken units without fixing the base will result in repeated breakage.

When to hire a professional: Single paver replacement is a reasonable DIY project for most homeowners. However, if multiple pavers are broken in the same area, if the base appears saturated or contaminated, or if the repair involves edge restraints or drainage issues, hire an experienced interlock contractor. Widespread paver breakage often indicates base failure that requires professional assessment and correction.

The repair typically costs $150-$400 depending on the number of pavers, accessibility, and whether base correction is needed — far less expensive than replacing an entire section.
