Concrete Under Pavers: Yes or No?

Using concrete under pavers is advisable as it provides a stable, long-lasting foundation that prevents shifting and sinking, and enhances safety by reducing tripping hazards. It also helps maintain the aesthetic appearance of paver designs by keeping them well-aligned and secure.

Introduction: The Debate on Concrete Under Pavers

The debate over whether to use concrete under pavers, especially around pool areas, centers on several key considerations. Each material offers distinct advantages and challenges:

  • Pavers: Known for their aesthetic appeal and variety, pavers provide a natural look with many design options. They are durable, slip-resistant, and relatively easy to repair, making them an attractive choice for pool decks. However, pavers can be more costly both in terms of initial installation and ongoing maintenance, as they may need regular upkeep to manage weed and moss growth.
  • Concrete: This is a more budget-friendly option that offers a uniform, stable surface. Concrete can also be styled to mimic more expensive materials and can be treated to enhance slip-resistance. Despite its durability, concrete is prone to cracking and can retain heat, which might make it uncomfortable on hot days.
  • Installation and Maintenance: Both materials require a well-prepared base; pavers use a crushed stone and sand base, while concrete is poured and smoothed over a prepared area. Long-term, concrete may have lower maintenance costs but can incur significant repair expenses if cracking occurs. Pavers, while potentially requiring more frequent maintenance, generally offer simpler, less costly repairs.
  • Safety and Comfort: For pool decks, safety is crucial. Both materials can be treated to increase slip-resistance. Lighter colors or reflective treatments are advisable for both pavers and concrete to reduce heat absorption, enhancing comfort around the pool area.

The choice between pavers and concrete ultimately depends on budget, aesthetic preference, and willingness to engage in maintenance. Working with a reputable contractor who understands these materials’ nuances is vital to ensure a high-quality, durable pool deck.

Benefits of Using Concrete Under Pavers

Concrete provides a reliable foundation for pavers, offering several benefits:

  • Stability: Concrete acts as a solid base, preventing pavers from shifting or sinking. This is crucial in maintaining the structure and appearance of patios, walkways, or driveways.
  • Longevity: A concrete base extends the life of pavers by providing a steady support system. This reduces the risk of cracks and other damages due to uneven settling.
  • Safety: By keeping pavers in place, concrete minimizes tripping hazards, making the surface safer for walking.
  • Aesthetics: Concrete helps maintain the intended design and alignment of pavers, keeping the area visually appealing.

Choosing the right base material is vital for the durability of pavers:

  • Crushed Stone: Offers excellent drainage and stability.
  • Gravel: Suitable for areas with poor drainage or high water flow.
  • Sand: Used with other materials but less durable alone.

Proper installation is key:

  • Preparation: Includes excavation and compacting the ground using tools like plate compactors.
  • Edging: Set up using materials like metal or plastic to contain the pavers.
  • Leveling: Ensures a flat surface using screed boards and string levels.
  • Finishing: Involves filling gaps and sealing pavers for added protection.

Potential Drawbacks and Considerations

  • Concrete pavers are known for their durability and versatility, ideal for driveways and patios. However, they are more expensive than poured concrete, both in material and installation costs.
  • These pavers are heavy, which can make adjustments or repairs challenging. Installation is physically demanding, and weeds can grow between pavers over time.
  • Crushed concrete, also known as recycled concrete aggregate (RCA), serves as an eco-friendly base for pavers. It’s less energy-intensive to produce than crushed stone and reduces the need for mining virgin materials.
  • Base material choices like crushed stone, gravel, sand, stone dust, and compacted soil each have their advantages and disadvantages. For instance, crushed stone offers excellent water drainage, while sand is easier to handle but less durable.
  • Stone dust can trap water, leading to instability, and compacted soil is vulnerable to poor drainage and climate effects. Choosing the right base material is crucial for the longevity of the pavers.
  • Concrete pavers are stronger than standard poured concrete. They require minimal maintenance and are easy to clean and repair. Properly installed and maintained, they can last 25 to 50 years.
  • While offering various design options, concrete pavers might not blend well with older, classic home styles. They are most suitable for modern aesthetic preferences.

Best Practices for Installation

  • Site Preparation: Begin with a clean, stable surface. If using existing concrete, ensure it’s in good condition without cracks or unevenness. For new installations, remove any debris and level the area.
  • Choosing Materials:
  • Base Layer: Opt for a robust base like crushed quarry rock or an open-graded base for better drainage, especially in areas prone to flooding.
  • Bedding Layer: Use sand or a synthetic material to provide a smooth surface for laying pavers.
  • Pavers: Select from various colors, styles, and textures. Consider durable options that resist scuffing and are easy to repair.
  • Installation Techniques:
  • Overlay Method: Clean the concrete base with a pressure washer, glue down border pavers, add a sand layer for drainage, and lay the pavers. Use polymeric sand to fill the joints.
  • Direct Method: For areas without existing concrete, lay the base and bedding layers accordingly before placing the pavers.
  • Finishing: Apply a high-quality sealant to protect the pavers from wear and stains, ensuring a longer-lasting finish.
  • Professional Advice: For complex projects or to guarantee precision, hiring a professional is advised. Visit our expert advice on paver installation for more detailed guidelines.
  • Maintenance: Regularly check and fix any moved or dipped areas, especially in driveways where vehicular traffic is frequent.

These steps will help ensure your paver installation is both aesthetically pleasing and durable.
