What we know today as MDPE was first given the commercial name of alkathene, introduced in the 1930’s. It’s used in a range of applications and because it’s not prone to stress cracking, rotting or corrosion and is inert (so it doesn’t support the growth of  fungi and bacteria), it’s the material used to transport water.

If you’re reading this, it’s likely you’ve had an unpleasant discovery while carrying out landscaping or groundworks recently – Black MDPE. Plastic pipes aren’t always covered on surveys which means you can sometimes find yourself in a challenging situation having broken through an old water pipe.

To make matters more frustrating, the diameter is often slightly different to the more commonly known blue MDPE which makes finding the fittings, couplings & adaptors can be a challenge.
