Questions and Answers

Q. Do I need all this heavy equipment for a 600mm tall wall?

A. Generally for walls under 1.0m tall on firm ground; all you need to do is remove the first 100mm of topsoil and replace with gravel.

 

Q. How much base coarse do I need?

A. Large walls on a soft sub base may need 300mm or more, while a small wall on a firm sub base may only need 25mm .

 

Q. Do I need a concrete foundation?

A. Most gabion walls can be built without a concrete foundation, however some supported walls and special engineer designed walls may require a concrete foundation.

 

Q. How test if my sub base is strong enough?

A. Engineers use a scala penetrometer to do foundation testing. A simple soil stenght test is to hammer a 12mm steel rod 500mm into the sub base, if you can do this easily your base needs to be replaced with base coarse.
