Fitting swimming pool lights

I,m having a frustrating day everything i touch has a problem. Thinking that getting the workmen to install ducting pipe for the electrical wiring while they are concreting was a good idea,big mistake.

Now i find that there are blockages from the cement, luckily there are only two. Its lucky I,m doing this before the tiles went down

That was yesterday today i will thread the cable and make ready for the 12 volt lights.
