Paver Installation on Mercer Island

Almost always because it was laid pack by pack rather than mixed as it went down. A blended range is manufactured with deliberate colour variation across the whole production run, and any individual pallet contains only part of that range — so laying one pallet out before opening the next produces bands of colour across the surface rather than a blend. The correct method is to draw from three or more packs simultaneously and mix as you lay, which distributes the variation evenly. It is a laying discipline that costs nothing and cannot be corrected afterwards without lifting and relaying the affected area.

A more exacting one, yes. A small unit sitting on a slightly uneven bedding course will bed down and find its level under compaction; a large one bridges the same imperfection and rocks, because there is no give in a big rigid slab. That makes the screed accuracy and the consistency of the bedding layer far more important than with a conventional size, and it means large formats are usually laid individually onto a properly prepared bed rather than compacted down as a field. They also need more people to handle, which is a labour consideration rather than an aesthetic one.

Thickness variation, mainly, and it is what separates a good stone installation from a poor one. Concrete units are manufactured to a consistent depth so a screeded bed produces a level surface automatically. Natural stone is split or sawn and varies within the same pallet, sometimes considerably — so laying it to a single bedding depth guarantees an uneven surface. Each piece has to be individually bedded to bring its top face to the correct level, which is slower and requires a different technique. Stone also frequently needs sorting and dry-laying before it is fixed, so the sizes and tones distribute properly across the area rather than clustering.

From the edge you will look at most, working the cuts to the edge you will not. Every paved area of a fixed size will produce cut units somewhere, and the only real decision is where they land. Setting out from the house, from a doorway or from the principal sightline puts full units where the eye goes and pushes the cuts to a boundary, a planting bed or a corner. Setting out from a convenient starting point instead — which is faster — frequently leaves narrow slivers along the most visible edge. It is a ten-minute decision at the start of the laying and it is visible for the life of the surface.
