A friend has asked me to install a security post at the end of his
driveway, the sort that lay down flat and lock. The problem is his
drve is block paving right up to the tarmac footpath apart from a
drainage channel. I have explained to him that the pavers are only
a few inches thick and that the post will act as a very good lever
if somebody wanted to remove it (and the pavers it will be bolted
to)!! He says it is only really as a visual deterrent. My question
is are pavers hard to drill and will they split under the pressure
from a rawlbolt. The post has come with a tube of No Nonsense
Injection Resin and four 12mm x 100mm self cutting bolts. I presume
the resin will be a waste of time in this application and that the
bolts are too long, would this type of bolt (but shorter) be better
than a Rawlbolt. How thick are pavers 2 1/2" or so?

Cheers

Attaching a post to a block paviour is a waste of time, as has been
said. You can either lift some and get concrete down, or you can buy
posts specfically designed for paviours. These have a long metal
tongue that lies on the paving, thus they bolt to several blocks. I
doubt theyre at all secure though, could just be lifted off the ground
I expect.

You might be able to whack some steel bar into the ground instead of
digging, concreting and relaying the blocks, but I dunno how you'd
connect it to the post, nor how vandal proof it would be. I'd go with
a big heavy lump of concrete.

The other main drawback with this is plastic gas and water mains which are
easily punctured, not to mention electricity mains.
