Form Framing For Stone Column Caps

wallmaxx

I helped my friend set up forms on his porch columns so he can pour 10 degree sloped concrete caps that will cover future stone wrap. I have never seen this before with concrete, but he said it was typical in FL, where he's from. I like the idea of concrete for the cap. Seems very low maintenance. Typically we just build the caps out of wood here.

I just love how downspouts do that over the columns.

It's interesting. It seems fine to me.

Showing off your Makitas are you? I am getting ready to buy the exact same thing. They are nice!

What's the material called you're forming with? Looks like plywood with masonite adhered on each side. Looks like slick stuff for forms.

D.Foster

Its MDO, medium density overlayment. Usually used on ext. applications signs etc.
I think.

?? The only MDO I've seen has more like paper on each face.

EDIT... the only plywood I can find with masonite on each side is something called "Armorboard".

D.Foster

I could be wrong,, is their a HDO, high density overlay??

Armorboard, cool i wonder if that would be a special order deal. Iknow masonite doesnt hold up too well to weather though right?

It'll hold up long enough to get the forms stripped, and there won't be any woodgrain marks.

I've built forms for a concrete cap on a chimney before. It seems like you would want to finish the caps like concrete counter tops when it's right at eye level though.

Nice jobsite radio!!! You guys like to break into a freestyle dance while your working?

"Check it, this form was put on by...... 'the robot'!" LOL.

Hard to tell on this monitor,
Could be HDO (AKA, architectural grade).
Used a lot for form work on
commercial work, especially slip forms,
columns, stuff that is reused a lot.

I wonder what the price diff would be between that and melamine? I'm sure melamine wouldnt hold up as well though for repeat applications.

If you made me guess, I'd guess not much at all. I hope Walmaxx reposts. He might just say it was scraps they had leftover and thought they'd use them up here.

wallmaxx

It's 1" thick (3/4" CDX plywood with 2 layers of the peg board type material laminated on each side.) The HO / builder got them from someone for free. They were all 4' x 5' (and very heavy) Some had circle cut outs along an edge, so I think they were for forms at one time. Maybe you can see the notch outs in this photo.

D.Foster

It looks like good stuff, i'd like to try it.

The music is a must.

I busted my DeWalt radio...so I revived my sound system from my old BOOM car days and power it with a 100 watt RMS per channel Yamaha home receiver into an MTX Terminator box.

A bit loud...but real c-l-e-a-n.

Tom Struble

so your wraping the post in concrete?

wallmaxx

The top gets a kind of Azek but off brand. Then the concrete cap (black dye to match the concrete deck). Then under the caps, wire mesh attached to the PT plywood for the mortar and finally synthetic stone to the mortar base.

The HO is a stone guy...he'll do good work.

We run our downspouts inside. would like to see pics when finished.
