Well designed grilles enable the tree to receive natural water, prevent surrounding soil from being compacted and add architectural flair to the paved surface. Designs vary to function best under different circumstances. Fine mesh grilles are offered where minimum change to the surface is needed. They will retain planting material and mulches but allow the free passage of pushchairs, wheelchairs, supermarket and shopping trolleys.
Circular grilles dive a dramatic effect when combined with imaginative blockwork patterns or can be used to break up large areas of angular paving. They may also be used in conjunction with the equivalent square designs.
