Most materials come in standard pack sizes, so quantities of things like insulation, bricks and blocks need to be rounded up. Contractors know that an allowance needs to be made for breakage, both in delivery and on site. Reclaimed materials for renovation projects have an even higher wastage factor. You may need to over-order by up to 20 per cent on second-hand bricks, slates and tiles compared to around five per cent for new. Better order too much than not enough. Any surplus can usually be sold or returned. Renovation work always costs more than you expect. This is because some problems are not revealed until you start work and uncover them, but mostly because items are forgotten from the budget, or because you change your mind and alter the design or specification.

If the wall runs up a hill, continue each base course into the hill until the top of the second course is level with the grade, and then start your second base course at that point. If you have the option, it can be easier to excavate and lay the lowest course before excavating the trench for the next step, especially if you have to step up several times. Save yourself some money and install the cheapest style/color that matches the wall style (usually the gray ones) on the bottom course since it won’t be seen.DON’T lay blocks on an unlevel surface. The first course (or row of blocks) sets the stage for the rest of the wall, so it’s vital that you make it perfectly level. If it isn’t, subsequent rows won’t be level either, resulting in a retaining wall that’s lopsided and unattractive. Use a four-foot carpenter’s level to ensure that the gravel layer below the first course of blocks is level before you start setting the blocks. Any discrepancies here will show up higher in the wall. DO stack blocks at a slight backward slope.
If the block Retaining wall is more substantial as in a metre high or more then the fence would have to be behind the wall instead of through or on top. Most Segmental Retaining Wall blocks do not have a big enough cavity or void for the fence post to be directly concreted inside them and would lack the strength to hold the weight of a fence. Generally, most walls are built using an aggregate (Gravel) backfill or in some circumstances No Fines Concrete (NFC). Because of this, an allowance has to be made for the fence post at the early construction stage such as installing PVC Piping as a sleave for the fence post to fit into, this would require some forethought and good planning.
