BEFORE INSTALLATION BEGINS
1. Confirm lot lines, wall location, wall length, set back requirements and elevations.
2. Confirm the on-site soils. For walls built in clay or poor soils, consult an engineer to confirm the wall
design and the required soil reinforcement. See Midwest Manufacturing Engineering for more details.
3. Call the local utility companies to confirm the location of underground utilities.
4. Obtain all necessary building permits and verify local building code requirements. An approved plan
may be needed to obtain a building permit for walls above a certain height.
5. For walls adjacent to property lines, at some time in the future a surcharge may affect the stability of
the structure. Contact the Engineer of Record to ensure that additional loading has been taken into con-
sideration.
6. Consider drainage and water management to avoid erosion or buildup of water behind the wall.
RETAINING WALL INSTALLATION

BEVELED
The design methodology for conventional gravity walls is based upon the following:
1. There is no slope behind the wall.
2. Surcharge loads applied at the top of the wall are limited to foot traffic where the applied forces will
be between 0-50 PSF.
3. There is good surface and subsurface drainage to prevent hydrostatic pressures at the back of the
wall and the reinforced soil zone.
4. The site soil has adequate strength to support the wall and good draining soils will be used behind
the wall. In addition, the ground water table is assumed to be well below the reinforced zone.
5. The cubic foot weight of the soil is the moist unit weight that includes the weight of water occurring
naturally in the soil.
6. Seismic loading is not considered.
7. The site can support the weight of the wall.
8. The foundation soil will not settle or deform to cause failure.
9. Keep in mind, conventional segmental retaining walls are generally effective as gravity structures for
most non-critical wall applications under 4 feet high, including the block below grade. For walls
exposed 3 feet or more, you must terrace the wall or use geogrid to reinforce the soil. Consult a
professional engineer for design assistance on taller walls. See Midwest Manufacturing Engineering for
more details.
