best decking fitting over concrete foundation?

Question

is it best to lay decking over an existing concrete foundation?

Nicu · Accepted Answer

Yes definitely, that makes the decking safer, but I suggested the frame be built on top of the plastic pins, to protect the timber from water.

Marc · Answer

Hi, yes it is on bearers so water can drain away from it

Samuel · Answer

No decking should belaid on 4 by 2 timbers not straight on top of concrete also a hammer drill is needed to drill holes in the concrete to secure timbers

Chris · Answer

It's not the correct way to lay decking at all, its best to pull the slabs up and start again from scratch.

Mandy · Answer

You shouldn't get weeds coming through but just getting the supports secure could be a problem

Gordon · Answer

Presuming the concrete base is level, then I see no problem with building your decking over it, should help your level of decking to be honest. 
Just make sure you don't have any dips in the concrete or the water will pull. If you do rescreed and drag a straight edge over it.

Gary · Answer

It can be a tricky job if the concrete is not a level base or at different levels but can be overcome.

Edward · Answer

Yes you can do that but obviously, you would build your frame as normal

Gavin · Answer

No, lay fresh concrete for better foundations for the decking

Jason · Answer

Yes but you would still be required to build a frame first
