I’ve been inspired by The Build Project and the Cinder Block Ledge by DIY Skate to build a ledge in the stormwater-run-off-turned-bike track (a place I call The Ditch) of a nearby suburb. This blog post documents the process of building my DIY ledge at The Ditch – from inception to implementation.
Identifying a location
This bank was going to be the location for my ledge, building on some concreting put-down by others. I changed my mind after discovering the concrete would somehow need to be made level and smooth for the best foundation. This would require a lot more work and tools that I don’t have. EAsier to choose a new location and start fresh. Besides, I can always build on this section later.
Determining best ledge length, based on cost, available space and materials.
Preparing the area
Excavation for flat bricks on opposite bank. The flat bricks provide a solid foundation for the masonry blocks (in the absence of a concrete foundation).
Excavation in detail. The amount of soil removed from the edge of the bank needs to accommodate the length and height of the flat brick, and the width of the masonry ledge.
Four blocks with caps. Not to low in height and not too high in cost (considering the likelihood of the ledge being demolished).
Length of ledge 1570 mm.
Experimenting with materials – Two masonry blocks (390 x 190 x 190 mm) with cap (390 x 190 x 40 mm).
Experimenting with materials – Three masonry blocks with cap.
