A real environmental example
The following demonstrates the comparison of concrete and ground screws to create the foundations for a 4.0m x 5.0m timber building installed in a plot of relatively flat land with good ground conditions. The impact on the environment of using concrete versus screw piles is clear.
A traditional base made of 16 x 0.125m3 concrete piers would use 2m3 or 4.8 tonnes of concrete - and requires a lot of digging!
The average embodied carbon in concrete is 358kg per 1m3, therefore the average CO2e = 716kg 1.
Alternatively, 16 RDX PRO 76mm x 1250m ground screws, each weighing 10kg or 160kg total, will produce a solid foundation without digging or damage.
The average embodied carbon in steel is 1850kg per tonne*, therefore the average CO2e = 296kg 2
Concrete Alternative Foundations
Overcoming challenging ground with minimal impact on our planet
Projects being installed in more challenging locations, with areas of sloping or soft ground, will require heavier excavations and significantly more concrete. In many instances, the project might not be possible at all.
Ground screws and screw piles can access remote and hard-to-access locations and bring up levels quickly with minimal impact by simply selecting longer screws.
They can also be built on immediately after installation, so they not only save the environment, they will save you time.
