A flexible liner impregnated with resin is pushed through the drain, whilst an airbag is also pushed through to mould the resin to the pipe. The liner is heated, and once cooled will mould exactly to the sides of the original pipe. Once the airbag is removed, it leaves behind a smooth new pipe inside the original.

That is a sleeve installed in existing pipe. Some sleeves are a moldable compound and injected and others are rigid.
