They have used this technology for over 10 years in States already including many commercial structures. They are also very helpful in converting your traditional engineering design into HelixSteel Alternative Design and provide you accurate cost estimates. I am strongly considering to give them a try on my ground slab and retaining wall.

This approach saves time (mainly steelworkers labour) and also creates more durable structures. Re: HelixSteel - 3D concrete reinforcement 4Nov 23, 2018 5:49 am Here's the irony, It would be useless alone in a Helix concrete stair case FYI Steel fixers charge $700 per Tonne (Perth) flat slab OT, That is a $1m Staircase in a $25m house BTW clients can't see your Helix..... it's .buried in concrete...get it.

Control joints may reduce ugly cracking during periods of soil… 3 9830 Hi all I need a guidance on how far I need to space expansion joints in the concrete driveway and its type (keyway/foam.) Contraction joints are at 3m max for a 125 slab. Thanks 0 10926 |
