Which type of Concrete to Use for a Totem Sign

[Jon Marshall]

I think its called Postcrete.

Hi Dave,

We generally use a GEN 1 or GEN 2 mix (fairly dry mix so it goes off quickly).

This will suffice for most installs, if you are going to bolt into the concrete it will be a different mix, ask your supplier for advice.

As Gil says, it’s "always best to ask the concrete supplier for advice".

Single post signs with something like a 610mm panel on it.
Fast installs of this type of thing, Post mix type bags bought from B&Q and other typical builders merchants will supply you this. you should be looking at about 2.5 – 3 bags per hole to backfill. Postcrete works too, but i dont like the fact it doesn’t have stone chips through it…

we normally prefer to mix the cement ourself as you get a better heavier consistency required for the base.
i.e.
3 bags of chips
two bags of sand
one bag of cement
add water to gain a good mix consistency but not too much water or the pole will move easy before its set.

when you move up the size of signage you really do need to take into account the window load.
wind load has many variables to take into account. the height of sign, size of panels etc etc
when your looking to back fill steel cages your looking at a mixer truck coming in on-site.
you will need to buy/drop cubic square metres of aggregate mixes into the cage. the cage size should give you a good indication of the amount of concrete needed. you’re probably looking at about £90 per square metre of concrete depending on your source it will vary upwards. your mix will combine what i have listed above, and remember not to ask for too wet a mix or it will be runny and take much longer to set.
