As explained in the FAQ , geo-membranes are optional but if there is any query regarding the competence of the sub-grade, they are a good investment.
Block Laying
- Laying of all full blocks continues, with the operatives working from the already laid paving, not from the screeded laying course. The bricks (blocks) are randomised prior to laying by selecting them from at least three open packs. this helps prevent blotching or banding of colours and allows the paving to show off the full range of hues to best effect.

This is a matter of personal choice as it is perfectly acceptable to use a splitter for clay pavers and it would be the first choice tool for most concrete pavers.
