New wooden floor - need to worry about DPC?

[keithk]

I am looking to lay a new wooden floor (oak t&g boards on 3" x 2"timber joists) on top of a solid concrete floor.

I was planning to screw the new joists to the floor but was a little worried about going through any DPC membrane that is likely to be under the screed.

Is this a problem or should I look to fix in another way.

Advice welcome

why not just glue direct to the subfloor

I nned to raise the level of the floor to meet with stone slabs laid in adjacent rooms.

what is the height difference can you get away with using a ramp from the stone down to the floor

 

[keithk]

Don't wamt to have a ramp

the way your are talking the difference in height is abot 100mm 75mm for the timber and 22mm for the solid oak the screed sould be atleast 100mm thick so if you want drill and plug the floor then screw the batons down I dont see a problem
