For a resin bound driveway, a permeable tarmac base is highly recommended over concrete. Here’s why:
Permeability: Permeable tarmac allows water to drain through the surface, preventing puddles and reducing the risk of flooding. Concrete, being non-permeable, can cause water to pool and lead to cracks and surface damage over time.
Flexibility: Tarmac possesses a degree of flexibility that helps it absorb and distribute loads more effectively, reducing the likelihood of cracks under pressure. Concrete, on the other hand, is rigid and can crack under heavy loads or ground movement.
While concrete may be chosen for its lower cost and easier installation, most Resin Manufacturers recommend a permeable tarmac base for its superior drainage, flexibility, and durability. Remember, resin bound surfaces are typically only 20mm thick, so a robust base is essential for optimal driveway performance and longevity, particularly in areas like Northumberland, Tyneside, and Newcastle upon Tyne.
