What can I retrospectively do to reduce the bounce of block and beam?

[Lal]

Our ground floor has block and beam and it has a noticeable bounce when we walk. Is there anything I can do to retrospectively fix this?

How long's the span? How do you plan on finishing the floor? Screed? If so, what depth?

[Alan Ambrose]

The obvious things would be central supports or screed. Neither should be that big a deal - although if you have not planned for screed it will obviously raise the level. An SE should be able to tell you exactly how much bounce you should have now and how much it will reduce. You’ve grouted it already? That will also make a big difference.

 

p.s. actually you don’t need an SE, an online beam bending calculator will give you some idea.

The weight of the screed will help, as would a full size snooker table. They will have been designed to have a maximum deflection.

have the blocks been grouted and any double beams infilled with concrete ?

Pretty sure the OPs house is finished and lived infor some time. Short of ripping up the floor and spending a fortune, nothing you can do.

Diet and move slowly.

You may be able to have an effect depending on what your surface is to be, depending how far you have gone so far with your structure.

Practically it needs the structure to be dampened or stiffened, or something else stiff being put on top.

 

But it's difficult, and far more fun to suggest alternative strategies:

 

1 - Use a Segway or in-line skates.

 

2 - Learn to love it.

 

 

Wishing you the best.
