Recommend a high strength gap filler please

[custardavenger]

Hi All.

I had a builder build my extension and though he got most of it right he did leave me with a few of his mistakes to fix. One is the edging to the inspection pit in the garage.

The image above shows the problem. When fitting the pit edge the builder didn't put down a bed of mortar first and as such the edge isn't supported. The gap varies with the brick work.

Can anyone recommend a product that I could fill this gap with? it mush be very strong under compression and also easy to apply to such a tight gap.

Thanks in advance

The metal is sitting on the brickwork so the silicon sealant required around to make it water proof will not be under compression.

The metal is not sitting on the brick work. It does sit on the odd high point but not well enough to take the weight of the pit jack and half a car.

So the brickwork is not level?
How is the frame secured to brickwork.?

The metal frame has welded brackets that go into the floor slab. I can take other pictures but you can see that some bricks are slightly high which it rests on and others are 2-5mm lower than the metal.

If that edging has to take the force of a pit jack sliding along it, I do think the frame needs to come up and then be well bedded down on mortar.
Sorry, but any sealants forced in are likely to be compressible to some degree.
Grouts are available for settling large machine beds but on this one I don't think you could rely on going where its needed!

Cheers John.

No way I can take the frame out now. It would ruin the slab and I don't think it's needed. I understand what you are saying but am sure with the right product it can be fixed easily. I am not going to use a sealant. I'm looking for a product that is designed to be good in compression.

Is it possible to use a cementitious grout by Sika.....we used to bed machines down with this as its pourable. I suppose it all depends on if you can pour the stuff in from above, to fill the gaps?
Certainly like most cementing compounds, it is excellent in compression.

The frame should be substantial enough to take the weights involved without buckling or its pointless installing it, a few mm gap is of no consequence, though there is no reason the brickwork should be anything other than level.
There is no magic product that will cure incompetence.

That would be correctly built brickwork.........

Yeah, well Builders eh. He's retired now and I need to find another one for other work on the house. Hope the next one is better but you can never tell until they do some work.

So anyone, know of any products that could help?

I would think something like this http://www.helifix.co.uk/products/remedial-products/concrete-crack-injection-repair-kit/ would work.

Cheers, Will look into that.
