Choosing the right aggregate is vital for the appearance, durability, and performance of any terrazzo or resin-bound floor. There are a range of materials available, each suited to different applications and design aims.
Popular Aggregate Types
For resin and terrazzo floors, natural washed pebbles are a popular option due to their versatility and visual appeal. Marble and granite chips are also commonly used for their durability and range of colours. When aiming for good drainage, rounded pebbles or porous stones can help ensure water passes through, making them excellent for outdoor settings. These aggregates can be combined to customise both the style and the function of your floor.
Mixing and Practical Selection
Aggregates typically range from 4 to 8 mm in diameter for optimal stability and permeability. When preparing your mix, always use clean, washed stones to promote strong resin bonding and prevent unwanted residues. For outdoor areas like patios and driveways, combining washed pebbles—such as the Washed Pebbles for Permeable Floors—with decorative marble or granite can deliver both resilience and aesthetics. For resin-bound systems, use a compatible binder designed for your chosen aggregate to ensure a stable, lasting surface.
When Aggregate Choice Matters Most
Aggregate selection is especially important if your project needs water drainage, such as in garden paths, driveways, or permeable patios. Using the right mix helps prevent puddling and keeps surfaces safe underfoot. In busy or shared spaces, opt for durable stones that can handle regular footfall while maintaining their appearance.
