Will aggregates discolour?
Most aggregates can discolour over time due to their porous surface and the build up of small particles around them. Westland aggregates are washed before packing to ensure they do not encourage algae and weed growth. If the aggregate is placed in an area protected from rain or in areas where there is rain splash from soil and dirt it is a good idea to hose down the aggregate regularly to eliminate the build up of dirt and soil on the aggregate.
