I would imagine you would get it in a builders supplier's yard.

Just out of curiosity why do you need to do this?

Thanks,I'm underpinning a chimmney.

A fair wee bit of work involved with that so.

Try giving this crowd a ring, they seem to have a wide range of products which could suit.

I remember having to glue threaded bar into a mass conrcrete floor at work a few years back, I think it was that crowd we dealt with. I do remember that the outcome was very successful.

What ever you go with do you mind posting back how you got on.

It's very common to see DIY underpinning just a dig and backfill with concrete job instead of making some effort to tie in the existing structure. I think cost wil be big factor when you go price this stuff (glue).

Ta, will do.

won't go wrong with "sika" range,anchorfix-1 is a fast curing two part epoxy for anchoring in brick, block, concrete,stone and solid rock should b available in most good builders providers. also used one called "resicon 5" very heavy duty but costly,think it was special order.

Thanks Do-more and dardevle for pointing me in the right direction. I ended up using a two part epoxy called Anchorset Red. Very handy to use as it is a twin bag system inside a standard sized caulking tube with a very long thin nozzle.

I had a chimmney that appeared to go straight up into the attic ( one story cottage) with an alcove to the right of the chimmney breast and then a bearing wall separating the next room . I needed to remove the bearing wall and create a bigger room. In the attic the chimmney doglegged to the right and was supported by the dividing wall which was built from 3'' solid blocks not 4''). The place was built in the 30's during the Economic War and the oldtimers around here tell me there was a dearth of good building materials.I'd say sea sand was used in the blocks and mortar.

So I built a pier in the alcove that rose up and supported the underside of the chimmney . Then I made up two temporary beams from 7''x2'' x16''s held together with coach bolts. Supported the ceiling on either side of the dividing wall with my beams and Acrows, drilled through this wall into the new pier, epoxied in my threaded rod and bolted this bit of wall to the pier. Cut the wall as deep as I could with my little Aldi Grinder and then stitch drilled the rest. Knocked the wall with a 10lb sledge and a Kango. Next job is to put in a RSJ and remove the Acrows.

Any pics: sounds like a good one to show:)
