i was planning on using a solid concrete base as there is already a small one there (its brand new) and i was just going to add to it i.e lay another slab of concrete next to it.
Self glueing studding sound good though.......never heard of it before, where can you get that from???
Sorry I may have indavertantly called the anchor system by the wrong name .
Look in the Screw Fix site for chemical anchors , the concrete needs to be cured , dry and carefuly drilled if close to the edge .
Because the chemical is absorbed by the concrete the anchor is a tremendously strong stress free way of making the anchor to the concrete .
You can buy the anchors in various quality plated steels or buy one metre lengths of mild steel gav studding fro B&Q or screw fix
Hilti do a very high spec stainless chemical anchors that you can cover the bolt and nut with thick nappy cream ( zinc and castor oil ) so it is easily freeable in years to come .
Some of the anchors work best if they have a fine stainless mesh sleeve over the stud down in the hole ( Hilti )
The glueing can be a dual shyrenge ( sp ) ) type tube set of epoxy glue and hardener that you use as a shyrenge or some times a caluking gun to squirt it down in the hole ..you need all holes drilled and de dusted so you can do the studs in a short time lest the adhesive starts to set in the mix/distribution nozzle.
You " progggle " the stud up down and around in the glue filled hole to get it evenly distributed .
Or you can use :-
Small glass or plastic capsules of pre mixed spirit based quick set glue that you slip in the hole and then push the studding on top and give a sharp tap with a hammer to rupture the capsule .
I prefered the glass capsules as a first choice , then the dual tube epoxy adhesive & caulk gun for the glass crushes to the bottom of the hole .
The plastic tube was my last choice due the the fact of them not totally falling to bits thus sometimes making the stud stand higher or to one side of the hole than you'd want .
You'll need a tube that is smaller than the hole so you can blow the generated concrete dust out, so you get a perfect clean dry surface for absorbtion of the glues .
The glues come at different anchoring strengths in the Hilti range.
