Waffle Slab Inspection

Join me for an inspection of a waffle slab before it is poured.

Check out our inspection of this waffle slab before it is poured. Give it a thumbs up if you’d like to know the 10 most important things to look for when inspecting a waffle slab.

Don’t forget to head over and sign up for your very own copy of our Protect Your Waffle Slab from Slab Heave manual.

And finally, don’t forget to post a comment on any one of our pages. We’d love to hear your ideas and questions

 

Stairway to Heaven

There’s a grad engineer who’s sure
All that external steel is hot dip gal
And he’s designing a stairway to heaven

Steel stairs to roof of warehouse

Jed was singing a song as he went about checking the recently constructed Stairway to Heaven at the brand new Sigma Pharmaceutical Distribution Centre in Berrinba today.

Well actually, it’s a permanent stair access onto the roof of the pharmaceutical giant’s new warehouse where solar panels and air-conditioning units will need regular maintenance and full time access.

We modelled it using SpaceGass before preparing a set of design drawings, checking some shop drawings and then a site inspection to make sure it was built to specification.

The whole facility (including the stair)  was built by big project specialist FK Gardner.

Stunning piece of engineering design by Jed from our Brisbane office and very nice fabrication. by FK Gardner. Great work team!

 

 

Termites And Cracked Slabs

Are you worried that termites could enter your house through cracks in the slab?

Well, it’s a possibility but according to research by the Cement and Concrete Association of Australia, a concrete slab designed and built in accordance with our current footing and slab standard AS2870 should keep the little critters out.

According to the CCAA data sheet, termites can’t get through cracks less than 1.4mm wide. Even though termites are smaller than that, they don’t like the rough concrete edges and have to mud line the crack to make it through.
