Divert sources of concentrated water flow from the wall.
Retaining wall engineering plans.
Bidding contractors estimate the materials labor and final engineering costs.
How tall is your wall.
The cost of proper engineering for a retaining wall is inconsequential when compared with the cost of repair and replacement of a deficient wall and the collateral damage that may result from it.
Retaining wall designs must prevent the pooling of water above or below the wall.
Develop a grading plan that routes water around the retaining walls as much as the site will allow.
If you have your retaining wall built figure about 15 per square face foot for a timber wall 20 for an interlocking block system or poured concrete and 25 for a natural stone wall.
Fortunately working with retaining wall blocks makes it incredibly easy to achieve.
Preparing a troublesome site one that includes clay soil or a natural spring for example can raise costs substantially.
The cost of a replacement wall could be on the order of 1 000 to 2 000 per foot plus the cost to repair any structure or paving adjacent to the wall.
Design and build your retaining wall to slope at a minimum rate of one inch for every one foot of rise height.
Provide swales above and below the retaining wall as required to accommodate water movement.
Alternatively specifiers often require the wall engineering plans to be provided as part of the retaining wall construction package design build.
