Is it practical to lift the boards and secure timber to the concrete to fix the boards to?

Lift the boards up....insert damp proof membrane and fill void with rapid setting concrete mix...once dry relay the boards and fix the boards to the new concrete to support the edges......then just insert the movement joint at the end of the boards..........

Any particular damp proof membrane and is there a cheap quick setting cement around as it will all come from my quote although i'd rather it be right 1st time than spend more money putting job right after problems.

Thanks steve.

Hi grumpy do you mean pull the boards over and fix to concrete? If so i'll have big height difference which would give me personally a bigger headache than filling in with cement.

Cheers Steve.

No mate, I meant that if you lifted the boards you could then put a supporting piece of timber along the internal side of the concrete and then extend the boards across, level with the concrete surface and secure the ends of the board to the supporting timber. Sort of like putting an extra joist in but only screwed/plugged to the concrete, if you see what I mean.

only option id use would be to lift the boards
stick a baton against the concrete edge and screw it to the concrete using a glue to hold in place also

then re lay the boards and screw to the baton

again using expansion joint where the 2 substrates meet


filler foam is good and sets hard just be careful not to go daft as it does expand but can be cut with a chisel if it goes proud

Bugger already cut boards and started to fill with trumix then was going to fill up and go over with sand cement mix. Saying that the concrete edge was all over the place. Will have to see how it sets.
In the other part of room there are vinyl tiles and stuck solid, cant get them up with my SDS either was wondering whether a clean and slurry coat over would be suffice. Here are some pics.

Thanks Steve.

What do you intend to do with the manhole cover?

 

[quick draw macgraw]

Its flush with the floor and sealed with no movement so was going to use flexi addy over this part only with normal over the rest.

BAL SPF will go straight over secure vinyl tiles. If they are rough you could skim over with BAL Acrybase first.
