Base for generator

[Taiaut]

My plan is to mount my standby generator on two four foot long pieces of 6 X 6 treated lumber. What would be the best way to attach the beams to a concrete pad
that is already there ? Would a liberal amount of Liquid Nails or Black Mastic be as good or better than drilling and installing anchors ?

Not a good idea to mount to a combustible

why are you not mounting it directly to the concrete pad? if for some reason the answer is that you need it to be slightly elevated, I think a few of the small concrete / cinder bricks used in sewage / drainage work, or a couple pieces of lightweight channel iron or I-beam would be better than wood.

"Ike" got within a foot vertically of the pad. And another foot above that puts it at house slab level. Figure if house floods I won't need the generator anyway. Was hoping the
wood would dampen a lot of vibration thus cutting down some on the noise. Large piece of wood out in the open is most difficult to set on fire. Using Natural Gas so no chance of fuel leaking and soaking into the wood.

Drill holes in the concreted, epoxy threaded rod into hole, put the 6x6 over the rod. Use a post base for a stand off to get the wood off the concrete like linked below. Bolt the whole thing down. How big is the generator?

You could build a simply cinder block and mortar structure and use anti-vibration material under the generator's feet, too.

Wood is within my skill level. Cinder blocks and mortar mix are not. Thanks for the first suggestion. I guess it would be smart to get the beam off the pad.

if you're concerned about vibration, these are used to mount airplane engines. I'm sure you could find the right size or something similar that would work.

Not a wise decision to install to a combustible

Get some concrete anchors from home depot. Threaded inserts that you drill a hole and drive them in. Then use threaded rod thought the wood. 3/8 would be plenty big enough. I would use steel and rubber pads for vibration instead of wood.
