What inceased maintenace could have prevented the slipway failure?

 

 

 

 

Possibly making sure shrubs/trees don't grow between the concrete slabs allowing water to wash away the earth below?

I would struggle to believe that the slipway was originally constructed with a void underneath it, if there was a void there all the time

If you lay concrete onto soil then a void will occur over time as the soil will dry out and naturally compact, add gaps in joints to allow water and the void will only get bigger unless the water is contained and then you have swelling, but that is not happening here.

I don't know how this dam was built but I cannot imagine there are no supporting pillars or walls beneath the slabs as they would have sagged or moved along time ago without something supporting them other than soil. 

With the thickness of the concrete and lack of re-bar there must be something other than soil holding that span of concrete up??

The pictures you posted on Sunday don't appear to show any supporting pillars or walls in the area of the collapse.

I cannot find any decent pictures of supports but this one may show something ??

Just a vaguely connected thought since we’re on the subject of water. If we as a country didn’t use seven litres of drinking water to flush a quarter litre of piss away ten times a day, perhaps we wouldn’t need to store so much water.

Eggs will prob know if its true but when I was laying drainage a few years ago I was told due to minimum fall levels n that...that pipes full of turds and wet wipes need the piss water to help move em along ...if you just flushed the solids and there was no rain then you may get problems? Also the water must dilute the raw sewage flowing around the system and help control gases and smells?
