Pattern or a continuous finish?
Monoblock has visible joints and a choice of laying patterns. A herringbone layout can give a frontage structure; a restrained border can make a compact space feel neat.
Resin bound gives a more continuous appearance, with colour coming from the aggregate blend. It can work around curves without the individual cuts and joints associated with blocks. Neither style is inherently better for a Scottish house: compare samples against the actual building.
Think about a future repair
Individual monoblock sections may be lifted and re-laid if the cause of movement is corrected. Matching old blocks can still be difficult, so retaining spare materials can help.
A resin repair may show a difference in colour or texture. Where access to underground services is likely, discuss that before deciding on a continuous surface.
Every surface needs some care
Monoblock cleaning may need to be followed by suitable re-jointing. Resin needs leaves and debris cleared and an appropriate cleaning method. Do not choose either on a promise that it will never need attention.
Sealing is a separate decision, not an automatic improvement. Use guidance specific to the product and the way the driveway was built.
Make the comparison specific to your driveway
Ask for the proposed base construction and drainage approach for each option. Do not compare one surface-only price with another price that includes excavation and a new base.
A good first conversation includes the approximate area, current surface, known drainage issues and the look you prefer. Photographs and real material samples can make the differences clearer.
