Alternatively specifiers often require the wall engineering plans to be provided as part of the retaining wall construction package design build.
Retaining wall engineering plans.
Retaining wall designs must prevent the pooling of water above or below the wall.
In such a case the specifier provides the retaining wall product type location layout grading and soils information.
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.
Provide swales above and below the retaining wall as required to accommodate water movement.
To determine if an engineering plan is needed for your retaining wall project take the time to evaluate the following.
Divert sources of concentrated water flow from the wall.
Develop a grading plan that routes water around the retaining walls as much as the site will allow.
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.
How tall is your wall.
Fortunately working with retaining wall blocks makes it incredibly easy to achieve.
Design and build your retaining wall to slope at a minimum rate of one inch for every one foot of rise height.
