This method is straightforward and can yield impressive results when done correctly. Additionally, ensuring a proper installation of a paver base is crucial to avoid future issues like cracking and shifting.
Adhesive Application Technique
Choosing the right adhesive application technique is crucial for successfully laying pavers over a concrete driveway. Start by selecting suitable adhesive types, such as construction adhesives or landscape block adhesive, ensuring they’re compatible with your concrete and paver materials.
Thoroughly clean the concrete surface to remove all dirt and debris, as this promotes a strong bond. Use a notched trowel to apply a consistent layer of adhesive, focusing only on the areas that will contact the pavers to reduce waste.
For edges, a caulking gun can provide a more precise application. Press each paver firmly into the adhesive to ensure full contact.
Always follow the manufacturer’s instructions regarding application thickness and curing time; proper bonding techniques are essential for durability.
Compaction for Stability
To ensure your pavers are stable and long-lasting, proper compaction of the base material is crucial before installation.
Begin by excavating the subsoil to establish a solid foundation. Use a mechanical compactor to compact any loose subsoil, which helps prevent settlement that could displace your pavers.
For the aggregate base, opt for crushed gravel, maintaining a thickness of 200-300mm for driveways and 100-150mm for patios. Use compaction techniques such as making at least three passes with a plate compactor for each layer of gravel. This maximises density and improves paver stability.
Finally, do a surface compaction after laying the pavers to secure them into the bedding sand, ensuring optimal interlock and durability for your installation.
