Priora Aggregate

• Add to project

Marshalls Priora Sub-Base Aggregate has been carefully selected for its superior void ratio and maximum internal angle of friction to ensure optimal performance of your permeable pavement both structurally and hydraulically.

The internal angle of friction has been thoroughly tested to ensure that it exceeds the BS and offers maximum interlock between particles. The aggregate has been graded to provide a void ratio of at least 32% (and up to 40%).

In addition, because our aggregate is supplied by a network of nationally sourced quarries, you can reduce the carbon footprint of your job by using the most local source possible for your aggregate.

Courtesy of our national network and market-leading buying power, we can offer this superior specification product to our customers for a lower rate than most ungraded alternatives.
