Filling void/cavity by bifold

Customer has a new bi fold door fitted.

New sand and cement screed fitted about 6 inch short upto the brick by the bi fold.

Can see black plastic between the new screed and the brick, but its been cut short. So no dpm.

Best way of filling this void?

I would imagine the concrete would need a suppressant anyway after the laitance as been removed.

Am I able to use a46 to fill the void, then go over the entire floor with mvs95?

Thanks guys

 

Take out the bricks. Add a visqueen sheet and fill back up with ardex na and granno chips

 

Thanks mate

Will overlapping the visqueen be enough?

 

I’d overlap them and tape them together with vapour tape.
