How deep should footings be for a retaining wall?
All footings should be a minimum of 150mm (6″) in depth, with the bottom 350 – 400mm (14-16″) below ground level on most soils. For clay soil however, thicker and deeper footings should be used.
Do retaining walls require footings?
A buried structural footing is usually required for larger retaining walls. To create this, a landscaper pours concrete below frost level (the depth to which the ground will freeze during the winter). Footings poured too shallow are prone to shifting and moving if moisture in the soil freezes and heaves.
How thick should concrete footings be?
Wall Footing Thickness. For masonry or concrete construction, the minimum foundation wall will be 6 inches. The minimum reinforced concrete footing thickness will be 6 inches or 1-1/2 times the length of the footing projection from the foundation wall, whichever is greater.
Can I mix my own concrete for footings?
For foundations, a mix of 1 part cement to 3 parts sand to 6 parts aggregates can be used. Measure around half of the cement, sand and aggregates (for a concrete mix only) you’re going to mix. Using half now will prevent the mix from drying out before you get chance to use all of it – you can mix the other half later.
Which wall needs to be stronger A or B?
The total bearing area of three 2x4s is 15 3/4 square inches; two 2x6s have a bearing area of 16 square inches. In bending, however, such as from a wind load, a 2×6 wall is considerably stronger. In tall walls, where column buckling might be a factor, a 2×6 wall would be stronger if a structural sheathing was used.

How deep should concrete footings be?
Depth of Footings Footings should extend to a minimum depth of 12 inches below previously undisturbed soil. Footings also must extend at least 12 inches below the frost line (the depth to which the ground freezes in winter) or must be frost-protected.

How does a unilock retaining wall system work?
All Unilock’s retaining wall systems have been engineered to work on the basic premise that the mass of the concrete units will counter the force of the soils being retained. To achieve this, units are simply stacked on top of each other using a runner bond pattern. The locking mechanism on each of the units interlocks with the units below.
