Best Aggregate Size for Pebble Floor Repairs

Choosing the right aggregate size is essential for repairing or renewing a pebble floor, especially if you want a surface that is both durable and comfortable underfoot. Here’s what you need to know to achieve lasting results.

Ideal Aggregate Size for Resin-Bound Pebble Floors

For most resin-bound pebble floor repairs and installations, aggregates (pebbles) in the 4–8 mm range are widely recommended. This size is a strong all-rounder, balancing good structural strength with enough comfort for walking and effective water drainage. Smaller stones can lead to surfaces that are dense and less permeable, while larger stones can create a rougher finish and may not bind as securely.

When Does Aggregate Size Matter Most?

Aggregate size is especially important for external surfaces exposed to rain, such as driveways and patios, where both slip resistance and puddle prevention are crucial. Using the right size ensures your repaired surface is safe, practical, and visually appealing.
