staying alive
I use square cabling trunking to try keeping my point wiring tidy. have tried
using silicon sealent to stick this to a concrete base but it keeps unsticking.
the concrete is too hard to drill screw holes
anyone got ideas on a permnant, waterproof adhesive ? cutting channels is not an option.
 
Concrete shouldn't be that hard to drill. Use a good masonary bit and a hammer drill.

I just drilled six concrete fence posts, two holes apiece, no problems.
 
i use a silicone based glue Called CT 1

one word,,,,,, awesome,,

the trade stand has a 450x450 slab stuck on to its side with four blobs and it just hangs there, no slippage

once you use this you will always have a tube handy, not cheap but worth every
penny,,, i pay about 13 pounds a tube and it comes in all colours
 
oh and if you want to drill concreate the blue granite range of drills from bosch
are fandabbydozy

i now use nothing else
 
problem with drilling concrete is the agregate content
if you hit granite pebbles its game over for a tidy job
 
I had never heard of 'gorilla glue' , and thought it was a joke until
I checked on 'net. bought it from a chap in cheddar, somerset.
quite right, ross, It not only sticks s*** to blanket, also trunking to concrete !
Many thanks for advice

POLYURETHANE GLUE (GORILLA GLUE). Boat builders (full size) use it.
See a Screwfix Catalogue.

Yep sold in Au as "Vyse" its a foaming gap filling glue. Exceptional stuff but does need to be kept cool once opened as it will self cure in the bottle if its not stored under 20c...

I used to test adhesives for work and though it was 11 years ago now I remember testing this stuff on aluminium angle in various joint configurations. In Lap joins the Aluminium failed before the polyurethane glue and in butt joints it was far superior to any of the other adhesives available.

Believe it ive drilled everything in my life but the lintals in my 1953 built house are something else ive been here 25 years and not once suceeded past the plasterwork it was only when i removed one did i realize they are 50% flint 40% rebar stuck together with a cement that you can not chip with a sledgehammer they are the pits and there is not a drill made that will penitrate them Until no nails came out The only way we ever got curtain poles to stay up were to screw a rail above the lintal near to the ceiling sorry for the drift but your post gave me shivers thinking about it

yes sometimes its beyond the scope of the normal tools and you need specialist equipment,,,,
yours is a cheeky one tony,,,
but glues have come a long way and as stated above gorilla glue, ct1, evodes wet grab
and even expanding foam have made my life much easier,,,
even the copper glue for glueing plumbing fittings is great and get you around a problem
but nothing is undrillable,,, just comes down to cost
