Frequently Asked Questions

1. What is the maximum load for a Mega Anchor?

30KN for a single 3 pile Mega Anchorr.


60KN for a 6 pile Double Mega Anchor.

2. Are Mega Anchors certified?


The Mega Anchor products are fully certified in Australia.

You can download the Mega Anchor Design Compliance Certification from the Mega Anchor Technical Information page.

3. Can I build multi storey buildings on Mega Anchors?


The limitation of the Mega Anchors is only limited to the design of the building. As long as there is enough anchors to support the building above, it is fine.

4. How long do the piles need to be?

When installing the anchors, piles are driven to practical refusal. This means they are driven into the ground until they cannot be driven any further.

A pile test is conducted on site prior to determine the length of the piles.

For more information, please download the Mega Anchor Technical Data Pack.

5. Can Mega Anchors be used on sloping sites?


The Mega Anchor is ideal for sloping and uneven sites as the centre riser can be adjusted to the required height easily.

6. Can Mega Anchors be installed into rocks?


In the event that rocks are encountered when installing Mega Anchors, it is possible to drill through the guides of the anchors and into the rocks.

7. How do I brace Mega Anchors?

With the Mega Anchor Bracing System.

A specialised bracing system has been designed to provide the best possible bracing for the Mega Anchor system. 

It consists of universal brackets that connect to the riser and either another riser or the brace anchor. This creates a brace that is much more effective than other methods of bracing.

8. Do I require engineering?

Yes and No.

The Mega Anchor is a pre-engineered product so there is no engineering required for the Mega Anchor itself.

The Mega Anchor installation process is self certifying, removing the need for engineers to specific pile depths.

However, you may require a professional, whether it be an engineer architect or designer to specify the quantity and locations of the anchors to ensure they support the building above.

It is important to include a Mega Anchor stump layout in the planning stages of your project.

For more information on engineering and technical data, please visit the Mega Anchor Technical Information page.

9. Is there a local supplier or installer in my area?


There is a selection of Mega Anchor suppliers and installers scattered throughout Australia. Please click on Find A Supplier page for more details.

10. How much does a Mega Anchor cost?

For pricing on the Mega Anchor manufactured components, please download the Mega Anchor Price List.

For pricing on an installed Mega Anchor, it will vary depending on the project conditions. Factors that will affect the cost include:

Ground  conditions: This will affect the length of the piles and will incur more cost with materials and installation time.

Location: If you are in a remote area, freight and travel time will increase cost.

The number of anchors being installed: Installing small quantities of anchors will end up being more expensive per unit.

Installation into rocks: This is a longer process and more labour intensive, which will add to the cost of overall installation.

Considering the above, the average price for a complete supply and install solution is around $200 - $300 per unit.

11. Do I require any special equipment to install Mega Anchors?


There are 2 main specialised tools required to install Mega Anchors correctly:

1. The Mega Anchor Alignment Tool

2. The Mega Anchor Jack Hammer Dolly

The alignment tool assists with aligning the Mega Anchor during installation to keep the anchor straight and plumb.

The dolly is the attachment that fits into the jack hammer so that the piles can be installed.

12. How long does it take to install a Mega Anchor?

15 - 20 minutes.

The installation time of a Mega Anchor will vary depending on the length of the piles and ground condition. The average time for installing an anchor is around 15-20 minutes with average pile lengths.

14. What is the pile material?

32NB Galvanised Pipe.

Pile material for all Mega Anchors is 32NB Galvanised Pipe (42.4mm OD). This pipe is available in different thicknesses. The thickness of a pile may be different depending on the application and location of the building.

14. What is the expected life span of a Mega Anchor?

50 years+ for the hot dipped galvanised Mega Anchors.

100 years+ for the stainless steel Mega Anchors.

The structural life expectancy of Mega Anchor is designed to comply with the Building code of Australia, to have a design life of not less than 50 years.

For longer term requirements, specialised paints can be applied, or a cathodic protection system can be incorporated.

The life span of a Mega Anchor may vary as it is a galvanised product and the coating will deteriorate at different rates depending on the location and soil type.

The stainless steel Mega Anchor has a structural life expectancy of 100 years+ in standard conditions.

All steel or stanless steel may corrode in extreme conditions or exposed to harsh chemicals.
