How Much Aggregate Do I Need for My Project?

← Back to Should I choose permeable paving for my driveway?

Getting the right amount of aggregate is key to a smooth resin driveway or permeable path project. Accurate calculation ensures a durable and consistent finish, avoiding costly excess or shortages.

Calculating Aggregate Requirements

For most resin-bound, permeable driveways or paths, you’ll need one 25kg bag of aggregate per square metre of surface. This guidance works when following standard application techniques for ResinPro’s systems. For example, if your driveway covers 20m², you’ll require 20 bags of aggregate.

• Accurately measure your total surface area
• Round up to ensure full coverage, especially for awkward shapes

Choosing Suitable Aggregate

Your choice of aggregate plays a vital role in the permeability and look of your finished surface. Pre-washed pebbles, like the Washed Pebbles for Permeable Floors, are ideal for both drainage and appearance. These can also be blended with marble or granite granules for a custom finish.

When This Matters

Using the correct aggregate quantity really matters if you want to maintain even strength and water drainage across the whole driveway. Underestimating can leave patches thin, reducing durability and risking uneven water flow.
