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.
How many 25kg bags would I need per m2 and at what depth should I apply the aggregates?
You will need to apply 2 x 25kg bag per m2 at a depth of 1-2 inches deep.
Should I use weed control fabric underneath the aggregates?
If you have a heavy infestation of perennial weeds such as docks and convolvulus, it is recommended to fit a weed control fabric underneath before applying aggregates. However, if the area is relatively clean from weeds or only has a light infestation of annual weeds a fabric may not be required. For the best results a fabric is recommended.
