Ground Cover for Pavers in Construction
In modern construction and landscaping projects, ground cover for pavers plays a vital role in enhancing aesthetics, improving functionality, and ensuring durability. Pavers are commonly used in driveways, patios, walkways, and outdoor living spaces, but the material that fills the gaps between them—known as ground cover—is equally important. Choosing the right ground cover not only prevents weeds and erosion but also elevates the overall look of the paved surface.
This article explores the types of ground cover for pavers, their importance in construction, installation techniques, and cost considerations.
Why Ground Cover Matters for Pavers
When pavers are laid for construction projects, the spaces between them require proper filling to prevent instability and damage. The right ground cover provides several benefits:
- Structural Stability: Keeps pavers in place and prevents shifting.
- Weed Prevention: Minimizes unwanted growth between gaps.
- Drainage: Allows water to flow properly, avoiding puddles and erosion.
- Aesthetics: Enhances the visual appeal of patios, driveways, and pathways.
- Longevity: Reduces maintenance needs and prolongs the life of the paved surface.
Types of Ground Cover for Pavers
1. Polymeric Sand
- Most common choice in construction.
- A mix of fine sand and polymer additives.
- Hardens when wet, locking pavers in place.
- Prevents weed growth and insect infestations.
2. Regular Jointing Sand
- Budget-friendly option.
- Does not harden like polymeric sand, so it may require frequent refilling.
- Provides good drainage but is less effective against weeds.
3. Gravel or Crushed Stone
- Excellent for rustic or natural-looking designs.
- Available in various colors and sizes.
- Provides strong drainage, reducing water damage around pavers.
4. Moss or Ground Cover Plants
- Natural and eco-friendly alternative.
- Adds greenery between pavers for an organic look.
- Popular choices include creeping thyme, Irish moss, and sedum.
- Works best in areas with light foot traffic.
5. Grout or Mortar
- Used in permanent, heavy-duty installations.
- Creates a seamless, stable finish.
- Best suited for patios or pool areas where weeds and shifting need to be avoided.
Choosing the Right Ground Cover
The ideal ground cover depends on the type of construction project and its intended use:
- Driveways → Polymeric sand or mortar for durability.
- Patios → Polymeric sand, gravel, or moss for aesthetics and strength.
- Walkways → Gravel, creeping plants, or sand for flexibility and design appeal.
- Outdoor Living Spaces → Moss or low-maintenance ground covers for a natural finish.
Installation Process for Ground Cover
- Prepare the Paver Base
- Compact gravel or crushed stone to create a stable foundation.
- Lay the Pavers
- Install them evenly, ensuring consistent spacing.
- Apply Ground Cover
- Spread polymeric sand, gravel, or chosen cover across the surface.
- Compact and Seal
- Sweep the ground cover into joints, compact with a plate compactor, and apply water if using polymeric sand.
- Maintenance
- Inspect regularly for weed growth, shifting, or erosion and reapply as needed.
Cost of Ground Cover for Pavers
The cost of ground cover varies depending on material, project size, and location.
| Ground Cover Type | Average Cost (per sq. ft.) | Maintenance Level |
|---|---|---|
| Polymeric Sand | $1 – $2 | Low |
| Regular Jointing Sand | $0.50 – $1 | Medium |
| Gravel/Crushed Stone | $2 – $4 | Medium |
| Moss/Plants | $3 – $6 | Medium–High |
| Grout/Mortar | $4 – $8 | Very Low |
Advantages of Using Ground Cover in Construction
- Prevents structural damage from shifting pavers.
- Improves drainage and prevents pooling water.
- Adds curb appeal by creating clean lines or natural aesthetics.
- Reduces maintenance costs by minimizing weeds and erosion.
- Boosts property value, especially in outdoor living spaces.
Conclusion
Ground cover for pavers is an integral element in construction and landscaping projects. Whether using polymeric sand for strength, gravel for drainage, or moss for a natural touch, the choice directly impacts durability, appearance, and maintenance. By selecting the right ground cover based on the project type—be it a driveway, patio, or walkway—contractors and homeowners can ensure a functional and attractive paved surface that stands the test of time.
FAQs
1. What is the best ground cover for pavers?
Polymeric sand is the most popular choice due to its durability, weed prevention, and ability to lock pavers in place.
2. Can I use plants as ground cover between pavers?
Yes, low-growing plants like creeping thyme, Irish moss, and sedum can add a natural look, but they require regular maintenance.
3. How often should I replace sand between pavers?
With polymeric sand, replacement is needed every 5–10 years. Regular sand may need refilling annually.
4. Is gravel a good choice for ground cover in driveways?
Yes, gravel provides excellent drainage and durability, but it may shift with heavy traffic unless compacted properly.
5. Do I need to seal polymeric sand after installation?
Sealing isn’t always required, but it can help extend the lifespan and improve resistance against stains and erosion.
6. What is the cheapest option for paver ground cover?
Regular jointing sand is the most affordable but requires frequent maintenance compared to polymeric sand.
7. Can grout or mortar be used outdoors?
Yes, grout or mortar is ideal for permanent installations like pool decks and patios, but it is less flexible than sand or gravel.
