Paver sand is primarily used to fill the joints or gaps between pavers, creating a stable and interlocked surface.
Key Use of Paver Sand
The main function of paver sand, particularly when referring to the type that hardens, is joint stabilization. According to referenced information, when mixed with water, it forms a strong binding agent that can be used to fill spaces between pavers, tiles, and more. This process is crucial for several reasons:
- Stabilization: It locks the individual pavers together, preventing shifting, wobbling, and movement over time.
- Weed Prevention: A well-filled joint makes it difficult for weeds to grow through the gaps.
- Insect Deterrent: It helps prevent ants and other insects from burrowing under the pavers.
- Drainage: While binding, it still allows for some water permeability, aiding drainage depending on the base layers used.
Application in Paving Projects
This type of sand, which forms a binding agent, is typically applied after the pavers have been laid. This type of sand is often used at the end of a landscape paving project with concrete, brick, or stone pavers.
Here's a general overview of its application:
- Sweeping: The sand is spread over the paved area and swept into the joints using a broom.
- Compaction: The area is often compacted again using a plate compactor to help the sand settle deeply into the joints.
- Wetting: The sand is then wet down following the manufacturer's instructions. This activates the binding agents within the sand.
- Curing: The sand is allowed to dry and cure, forming a hard, durable joint filler.
Using paver sand effectively ensures the longevity and structural integrity of paved surfaces like walkways, patios, and driveways. It provides a clean, finished look while protecting the underlying base layers from erosion through the joints.
