During wall layout it is important to evaluate the entire site to determine if water will drain into the area where the walls will be constructed. Using simple berms and swales to divert the water around the wall can be easily done. Since walls are often built before the site is completely graded to its final configuration, temporary grading must be in place to ensure water will not be draining towards the construction area. Contact the local engineer of record and the site civil engineer for directions prior to proceeding with construction of the wall.

Ground water can be defined as water that occurs within the soil. Sources include surface infiltration, water table fluctuation and layers of permeable soils. Ground water movement must be prevented from coming in contact with the retaining wall structure, including the reinforced soil mass.
Construction details to prevent subsurface water from coming in contact with the retaining wall structure should be defined on the approved plans. Use blanket and chimney drains to intercept ground water from potentially infiltrating the reinforced mass. When ground water is encountered during construction work with the engineer of record to ensure that the water has been accounted for in the design.
Extra care must be employed to prevent water from entering the reinforced zone when non-permeable infill soils are used in wall construction.
Drain pipes used in toe or heel drain applications must be properly vented a minimum of every 50 ft (15 m). Methods to accomplish this include having drain pipes draining into the storm sewer system or vented to a lower elevation on the site. See approved plans for locations.
When venting to a lower elevation, it is important that all drain locations are properly marked during the construction phase and protected during and after the completion of the project to ensure that the drain pipe is not damaged or plugged. Rodent screens and concrete collars are examples of details employed to allow for water to flow through the outlet pipes and keep the pathway clear of debris. If details are not identified on the plans, request guidance from the local engineer or the site civil engineer.
Concentrated Water Sources
Prior to constructing the wall, review drainage plans and details with the general contractor or site civil engineer to identify all potential sources of concentrated water.
Examples that must be accounted for are:
Below grade storm sewer pipes
Water lines, mains or fire hydrants
Grading of site
Catch basin to storm sewer system
Roof down spouts
Slopes above walls
