GRIZ... Looks GREAT.....

Pardon my ignorence.... but could you explain that assembly to me...

looks like 3/4 solid (obviously not prefinished).... and if it's floating it must be a TnG "glue-up"... so how do you keep your TnG tight... raw unfinished can't come that true, can it.

What type of underlayment/cushion did you use.

Thanks.... My flooring is limited to naildown solids and floating/glue-down engineereds...

Merry Xmas

How many on the crew, how long did 8800 take ya?????

Hey Peter,

The floor sets on top of 7/16 OSB which in turn sets on top of 2"x3"x4' sleepers. with cushion pads attached, that float on the slab (on top of vapor barrier).

Three guys put this down in 4 days.

One question, I remember you saying a bunch of time and money was spent leveling and grinding that slab, couldn't all the variations of been fixed with the subfloor material?

No. Manufacturers spec, 1/8" in 10', because it is a floating floor. Bad slab on a floating Gym floor makes a nasty thud when a BB bounces off of it.

Is it really possible to get a floor 1/8" in ten feet with a screed alone?

It's possible, but difficult.

Takes a real pro concrete crew.

Laser screed & nominal grind/fill seems to work best.

only 1 layer 7/16 OSB?

what sport system is this?

it wasn't a double offset layer?

every suspended sport floor ive done required 2 offsetting layers.1 strait 1 45 over the top.

I cant any system utilizing only one layer 7/16..

were the screeds fastened to the OSB prior to install?

No, they float. Runners laid out then OSB installed.
