Drilling into a "damproofed"wall?

Im going to be working on a job in a few weeks that has had the external walls of the property tanked with waterproof render, not the bubble wrap type of stuff. I don’t want to compromise the damproofing that has been done but also need to fix the skirting, radiators and a boiler to the same walls.
The surveyor has said to use sika plugs in the holes instead of normal plugs, but I can’t find any more info about these sika plug fixings?

Has anyone on here had any involvement with this before, or better still does anyone work for a damp proofing company that could advice about them.

Thanks

Contact sika?

I have tanking installed and I got told to stick silicone into the drilled holes and make sure it is sealed.

Sika plugs?

There is a company called Sikaflex that do super strong adhesives. It might not be sika plugs, he may mean fill the hole with an appropriate Sikaflex product and then just push the screw in and let it set before bearing a load?!
