So on delivery of the various bits and bobs for working on my garden today, I found out from the delivery guy that all the quarries in the country are closed. They're delivering out pre-packed stock, but you can't get tonne bags of sand or gravel, and they're expecting to run out of all aggregates and cements in fairly short order. This stuff doesn't operate on JIT supply chains the way food and commodities does, and has relatively robust stockpiles, but those stockpiles can't last forever. Even with the truncated work schedules and most construction being shut down for the duration, we're looking at probably a good month after the lockdown ends before the supply chain for aggregates and cement gets back into gear again.
