Interlock Pavers Guide
Everything you need to know about choosing and installing pavers in Northumberland County
Interlock pavers are one of the most versatile and durable hardscaping materials available for Northumberland County homeowners. Unlike poured concrete or asphalt, pavers offer flexibility, easy repairs, and endless design possibilities. This comprehensive guide will help you understand your options and make informed decisions for your patio, driveway, or walkway project.
Why Choose Interlock Pavers?
Easy Repairs
Individual pavers can be lifted and replaced if damaged, unlike concrete that requires complete replacement.
Freeze-Thaw Resistant
Pavers flex with ground movement during Ontario's freeze-thaw cycles, preventing cracks common in concrete.
Design Flexibility
Hundreds of colors, shapes, and patterns allow truly custom designs that complement your home.
Long-Term Value
While initial cost is higher than asphalt, pavers last 30+ years with minimal maintenance.
Permeable Options
Permeable pavers reduce runoff and help manage stormwater on your property.

Permeable Pavers
Permeable pavers are an eco-friendly solution that allows rainwater to pass through the surface and into the ground below. They're increasingly popular in Northumberland County for environmentally conscious homeowners and for managing stormwater runoff.
How They Work:
Permeable pavers have larger joints filled with small stones rather than sand. Water flows through these joints and into a specially designed aggregate base that stores and slowly releases water into the soil.
Benefits:
- Reduces stormwater runoff
- Replenishes groundwater
- Filters pollutants from water
- May qualify for municipal incentives
- Reduces ice formation in winter
Installation Requirements
Permeable pavers require a deeper base installation than standard pavers:
- Excavation: 12-18" minimum depth
- Base Layer: 8-12" of clear stone (no fines)
- Bedding: 2" of smaller clear stone
- Pavers: Permeable-rated units with spacers
- Joint Fill: 1/4" clear stone (not sand)
Paver Type Comparison
Installation Overview
1. Planning & Design
Measure your space accurately and create a design. Consider drainage patterns, sun exposure, and how the space will be used. Check if permits are required for your project in Northumberland County.
2. Excavation
Remove existing material to the required depth (typically 8-12" for patios, 12-15" for driveways). Ensure proper slope away from structures (1/4" per foot minimum).
3. Base Preparation
Install geotextile fabric, then add and compact aggregate base in 4" lifts. Proper compaction is critical for longevity - use a plate compactor for best results.
4. Bedding Layer
Add 1" of bedding sand (or HPB for better drainage). Screed to create a perfectly level surface. This layer compensates for minor base imperfections.
5. Laying Pavers
Start from a straight edge and work outward. Maintain consistent joint spacing using manufacturer spacers or eye. Cut pavers as needed using a wet saw or splitter.
6. Edging & Restraint
Install edge restraints to prevent paver spreading. Plastic, aluminum, or concrete edging options are available depending on your application.
7. Compaction & Joint Sand
Compact the surface to set pavers into the bedding layer. Sweep in joint sand (polymeric sand recommended) and compact again. Activate polymeric sand with water per manufacturer instructions.
Maintenance & Care
Regular Maintenance
- Sweep regularly to remove debris
- Pressure wash annually to remove stains and algae
- Refill joints every 2-3 years if using regular sand
- Remove weeds promptly if they appear
- Seal every 3-5 years (optional but recommended)
Winter Care in Northumberland
- Use plastic shovels or snow blowers (no metal blades)
- Apply sand for traction, not salt
- Remove snow promptly to prevent ice formation
- Avoid de-icing chemicals - they can damage pavers
- Repair shifting caused by frost heave in spring
Common Issues & Solutions
Sunken Areas
Usually caused by insufficient base compaction. Lift pavers, add base material, recompact, and reinstall.
Weeds in Joints
Prevent with polymeric sand. Treat existing weeds, remove, and refill joints properly.
Stains
Most stains can be removed with pressure washing. Oil stains may require commercial degreaser.
Efflorescence
White powdery residue from salts. Usually disappears naturally; can be cleaned with specialized cleaner if persistent.
