Now on the internet a see that self levelling concrete (SLC) is recommended. However the floor is on a slight slope ~25mm over 2.7m width or the room, the slope is relatively constant/ i.e. in a straight line.
I'm not sure but I think using SLC means I would need to get rid of the slope as well as the relatively minor bumps and dips from linear.
The room is a study so I don't really care about the slope I just want the laminate to not creak and last a while. Is there a way to get rid of the minor deviations without tackling the slope?
I think I will probably move out in a year or two, would it be easiest to just lay the laminate as is?
