fixing to areated block walls

frankie

Just moved into a house that has thermalite type blocks covered with dab and plaster.

Any recommendations of what fixings to use for securing wall cupboards. There seems no holding capacity on this type of wall construction, wall plugs just pull out, plasterboard plugs not strong enough to hold cupboards. frame fixings just come lose as block seems to disintegrate. Do I need to go through the resin injection route?

I real PITA!

Chemical fixing are the best in my opinion for high load fixings such as fitted wall units, but you could try some form of expanding bolt rawlbolt/screws or similar.

As an aside an awful lot of the actual load of a kitchen unit is directly downwards, securely fixing a decorative timber batten under the unit takes the load off the actual fixing bolts.
Can then be used to hang utensils etc. I've always done mine this way regardless of wall type.;)

I've just installed a large wall mounted TV for my son into exactly that type of wall construction. Previously we fixed several wall cupboards in the kitchen, using the same expanding fittings. Absolutely no problem at all with the security of the fixings.
However, I would make the point that cupboards full of crockery are extremely heavy and this should be borne in mind when fixing. The batten idea is a good one, I have used it myself on other occasions. It also ensures that the cupboards are aligned correctly.

There is another point though that I failed to mention;

You need to be pulling into the blockwork rather than pulling out of it.

By that I mean that most fixing fail because the lift a chunk of block from the wall.

If you fix in the back 1/2 of the wall. in effect you are trying to pull the whole wall over, and that's the idea, ;):D
