Premixing | Can be done by machine | Separation during transportation and installation |
Risk of soil compaction in voids |
Can require special mixing equipment |
Water mixing during installation | Contact between stones is ensured | Can require large volumes of water |
Independent of weather | Most suitable at large aggregate sizes |
Prevents soil compaction | |
Dry mixing during installation | Contact between stones is ensured | Dry weather required |
Prevents soil compaction | Requires dry soil |
Sand mix | Rational mixing with right equipment | Risk of soil compaction to a degree that impedes root growth |
Inexpensive ingredients | The compaction level must be controlled |
Easy to install | Poor load-bearing capacity |
