Hi there,

Does anyone know if MDPE under ground pipe has to be protected in some way when being buried in concrete?

Thanks in advance 🙂

if it was me and the concrete was permanent eg under a house/building i would make a duct out of 4" soil pipe so you could always replace the mdpe at a later date if you had to

Yeh always protect the pipe through concrete by using ribbed ducting same as new builds , or drainage , how much length will be in concrete, ?

Hi Kris,

Yes, it's for mains water. The pipe would be roughly 15 meters under a patio going to an outside tap. Thanks for the quick reply!

How deep is it? I mean 700 to 900mm is a lot of concrete? Usually through founds it's a sleeve . But sounds to me like your going to need more protection from frost than concrete. Concrete may destroy it in 5 years
Frost could do it by end of the year!

Yes, I have made the customer aware of potential cold weather damage as it's only about 12 inches underground, but he says he is willing to take the risk. Customers - what can you do!

bit overkill if you ask me but have you had a price on Uponor Thermo?

Sleeve it in 6" duct use 19mm armourflex or external wet rated lagging and pull it in. Pull in a spare draw rope too

Be blooming expensive for an outside tap mate!

yes but once you add up duct, Armour flex etc wont be too far off

dig a deeper trench and do it right so it wont freeze, as you will get the blame down the line, when they throw the regs back at you

As said id do the job properly the first time, it might be a bit of work digging between 750mm -1300mm deep but the headache when it comes back to you a few years down the line wont be fun, and the customer will blame you as your the professional
