This 7,800 sq. ft., 6” thick industrial warehouse concrete slab is reinforced with a 1’ grid of 10 mm steel rebar. We poured over 140 cubic meters of 32 mpa concrete. Foundation walls we completed 2 weeks ago required 70 cubic meters of concrete. In total, it equates to approximately 22 residential driveways worth of concrete poured!

It is not just the volume of concrete used that pushes this job to the upper scale of our projects line up for 2024. Each phase of this project is subjected to strict engineering specs and inspections.

“We have to pass geotechnical engineering inspection for the slab, structural engineers must sign off on the steel structure portion and civil engineers to inspect and approve all civil works”, says Don Moore, owner of Moore & Sons Contracting.

“Everything has to be precise. Anchor plates that we put into the foundation have a 2mm tolerance, meaning every bolt in the foundation can only be off by 2mms. There are total of 64 bolts that have to be precise, so we had about 3 days worth of surveying done to make sure they are all at right spots. “

Project foreman Trevor Alderstein explains how pacing concrete trucks 15 minutes apart, allowing it be continuous pours through 40-metre pump, results in a final product quality we want.

“When the pour is continuous, we don't get cold joints, which means it results in much stronger slab”, says Alderstein.

The other precision spec we must deliver is 16” slope from the front to the back. With the use of our laser screed, we were able to ensure the whole slab is sloped properly.

This has been about 3 months project from start to finish, from excavation to pour, and our team at Moore & Sons is proudly signing off with before-schedule and under-budget completion.
