How the Crushed Stone Footing Works
The physics of the crushed stone footing are simple:
1. The purpose of any wall footing is to distribute the wall’s load over a sufficiently large area of soil so that the weight-bearing capacity of the soil is not exceeded.
2. The load of the building is carried by the Superior Wall and is transferred to the crushed stone. 3. The load distribution path through the crushed stone is at an angle approximately 60 degrees
from the horizontal. 4. As the depth of the crushed stone layer increases, the effective bearing width on the underlying
soil also increases (see drawing below). 5. The tables in this booklet identify the required depth of the crushed stone footing for various wall
loads and soil bearing capacities.

Site Preparation Soils Verification 1. Determine your soil type from Table 1 on this page and stone depth requirements from Table 2 on
page 6. For assistance identifying your soil type consult with: • Building Department • County Agricultural Extension Service • County Conservation District Officer • Soils Technician / Engineer • Excavator
2. Determine allowable foundation pressure and drainage characteristics (see Table 1). This will affect the required depth of the crushed stone / gravel footing.
3. Establish combined footing load per linear foot. (Consider dead load, live load, snow and wind load.) Acquire loading from building designer or engineer.
4. Determine required depth of crushed stone / gravel footing. (From Table 2. Remember to allow for this depth when determining excavation depth.)

Excavation Excavate a typical basement.
• Be sure to confirm that you are working from the approved drawing prior to digging.
• See Figure 2 on page 8 • Allow a 2’-0” overdig at base of
excavation. • Ensure compliance with OSHA
regulations. • Slope grade a minimum of 6” fall within
the first 10’-0” to divert ground water from the foundation area.
• Remember to dig for sump pit.
R401.3 Drainage. Surface drainage shall be diverted to a storm sewer conveyance or other approved point of collection so as to not create a hazard. Lots shall be graded so as to drain surface water away from foundation walls. The grade away from foundation walls shall fall a minimum of 6 inches (152 mm) within the first 10 feet (3048 mm). Exception: Where lot lines, walls, slopes or other physical barriers prohibit 6 inches (152 mm) of fall within 10 feet (3048 mm), drains or swales shall be provided to ensure drainage away from structure.
R404.1.6 Height above finished grade. Concrete and masonry
foundation walls shall extend above the finished grade adjacent to the foundation at all points a minimum of 4 inches (102 mm) where masonry veneer is used and a minimum of 6 inches (152 mm) elsewhere.

Drain System / Sump Pit Install auxiliary drain pipe.
• Use 4” perforated pipe, see Figure 1 on page 6. • Locate pipe according to Table 3 on page 7. • Direct pipe to sump or daylight drain.
a) Sump Pump, supplied by others, must be checked regularly to ensure proper working order.
b) If a daylight drain is used, install a trap to prevent the backflow of moist air into the stone footing area, which will reduce the likelihood of excessive interior humidity. (See illustration below)
• Install filter membrane prior to backfilling. Install Sump Pit
• For large foundations and in areas where you expect a high water table, you should consider using a second sump pit. (or a second outlet to daylight)
R405.1 Concrete or masonry foundations. Drains shall be provided around all concrete or masonry foundations that retain earth and enclose habitable or usable spaces located below grade. Drainage tiles, gravel or crushed stone drains, perforated pipe or other approved systems or materials shall be installed at or below the area to be protected and shall discharge by gravity or mechanical means into an approved drainage system. Gravel or crushed stone drains shall extend at least 1 foot (305 mm) beyond the outside edge of the footing and 6 inches (153 mm) above the top of the footing and be covered with an approved filter membrane material. The top of open joints of drain tiles shall be protected with strips of building paper, and the drainage tiles or perforated pipe shall be placed on a minimum of 2 inches (51 mm) of washed gravel or crushed rock at least one sieve size larger than the tile joint opening or perforation and covered with not less than 6 inches (153 mm) of the same material. Exception: A drainage system is not required when the foundation is installed on well-drained ground or sand-gravel mixture soils according to the Unified Soil Classification System, Group I Soils, as detailed in Table R405.1. Flow Direction
Code Reference: 2003 IRC Section R405.1
Note: Section R405.1 requires a drain around concrete foundations. It notes that gravel or crushed stone drains are permitted (see reference at right). The Superior Walls system utilizes the crushed stone footing as part of the code identified drain and also requires an auxiliary drainage pipe for redundancy. This auxiliary drain pipe should be permitted either inside or outside the wall. Consult your local code official for clarification.
Superior Walls does not permit the utilization of this exception.
Example of a Backflow Trap

Crushed Stone Footings Place the crushed stone footing.
• Depth of stone was determined on page 5 using Table 2 on page 6.
• Use clean crushed stone, washed gravel or coarse sand. • Superior Walls recommends clean crushed 1/2”
AASHTO #8 or smaller. • If crushed stone footing is deeper than 8”, place in 8” lifts
and consolidate each lift with a plate vibrator. • Evenly grade the stone to +/- 1 inch of level. • Be sure to have enough material on hand for use in final
grading by the wall installation crew. • See Figure 1 on page 6.
R401.2 Requirements. Foundation construction shall be capable of accommodating all loads according to Section R301 and of transmitting the resulting loads to the supporting soil. Fill soils that support footings and foundations shall be designed, installed and tested in accordance with accepted engineering practice. Gravel fill used as footings for wood and precast concrete foundations shall comply with Section R403.
R402.3 Precast concrete. Approved precast concrete foundations shall be designed and installed in accordance with the provisions of this code and the manufacturer’s installation instructions.
R403.2 Footings for wood foundations. Footings for wood foundations shall be in accordance with figures R403.1 (2) and R403.1 (3). Gravel shall be washed and well graded. The maximum size stone shall not exceed 3/4 inch (19.1 mm). Gravel shall be free from organic, clayey or silty soils. Sand shall be coarse, not smaller than 1/16 inch (1.6 mm) grains and shall be free from organic, clayey or silty soils. Crushed stone shall have a maximum size of 1/2 inch (12.7mm).
Cold Weather Practice
• Do not excavate the site too far in advance of the scheduled set date. Do not place footing on frozen soil. • After the site has been excavated, insulate the area where walls are to be set and protect this area with a
waterproof covering. • Mixing calcium chloride into the stone footing and then covering it will help prevent frost infiltration. (Do not
forget to treat the “extra” stone pile – you may need it to fill-in low spaces in footing.) • Note that 6 inches of straw has approximately the same “R” value as 3 ½” of fiberglass insulation (see chart
below).
Insulating Values of Common Building Insulation Materials Insulation Material Approximate “R” Values
1” of Straw 2.0 ½” of Plywood 0.6 1” of Fiberglass Batt 3.3 1” of Extruded Polystyrene 5.0 Insulated Blankets or Tarps Per Blanket Manufacturer
These recommendations are compiled from a variety of industry sources.

Corner Pin and Benchmark Placement • Establish a benchmark to identify your required top-of-
wall elevation. (Clearly communicate the elevation requirements to your Superior Walls supplier.)
• Set pins that define the building corners. • Pins should represent the exterior face of the Superior
Walls foundation. • Check with your Superior Walls supplier or sales
representative for specific requirements. Road Accessibility / Overhead Obstructions
• The driveway must be wide enough to allow for trailer and crane access.
• The driveway surface and any culverts or bridges must be able to accommodate the weight of the vehicles.
• 9’-0” and 10’-0” walls are delivered on a drop deck trailer and have limited ground clearance.
• The Builder / Homeowner is responsible for any additional equipment or costs necessary to provide access to work area. Consult with your Superior Walls supplier or sales representative for specific details for your jobsite.
• Verify that trees, wires and other overhead obstructions do not block site access.
Crane Accessibility
• Access to the foundation area should be prepared so the crane can be positioned in a location that allows it to reach to either side of the foundation or as specified on the drawing.
• Prepare a level crane pad area with a solid base, free of overhead obstructions (trees, wires, etc.) next to the foundation.
• Provide a level area for the trailer to be parked near the crane.
• Consult with your Superior Walls supplier or sales representative concerning specific details for your jobsite.

Backfilling Recommendations WARNING: To comply with building code requirements, the framing / decking connection at the top of the Superior Wall and the floor slab at the bottom of the Superior Wall MUST be completed prior to backfilling! • It is the builder’s responsibility to insure proper site
conditions. • Do not use expansive soil or topsoil for backfill. See soil
chart Table 1 on page 5. • Backfill must not exceed 60 pounds per cubic foot
(PCF) equivalent fluid pressure (EFP) for any Superior Walls application.
• Maximum allowed height of backfill is 6” below the top of the Superior Wall.
• Always slope ground away from the foundation according to local code or not less than 6” fall within the first 10 feet. Provide functioning rain gutters, downspouts, and run-outs.
• Allowing heavy equipment to operate near backfilled walls may adversely affect your Superior Wall installation.
• In a condition where there is more backfill inside than outside, never exceed a 36” differential in fill heights.

HOMEOWNER GUIDE Rev: 11/23/05 Additional copies of this Homeowner Guide are available for download at www.superiorwalls.com. Controlling Humidity and Condensation Modern construction methods have resulted in tighter, more energy-efficient homes that require planning for the control of humidity and condensation. Because a Superior Walls wall panel is constructed with a high-performance concrete mix and lined with closed-cell foam insulation, it prevents the free flow of moisture through the wall panel. Though this is a good thing when seeking to keep ground water out of your basement; it also acts to keep moisture vapor inside the house. In certain conditions of high interior humidity and low exterior temperatures, it is possible that condensation may form on the interior surface of the Superior Walls panel. Condensation can occur anytime moist air contacts a surface that has a temperature less than the dew-point of the air. Condensation may be controlled in a number of ways:
1. By reducing the amount of moisture in the air: a. Limit moisture-producing sources or activities like non-vented clothes dryers, space heaters or hot-tubs. b. Use a dehumidifier.
2. By preventing the moisture from reaching the cold wall surface: a. Use a vapor barrier (vapor retarder). b. Remove the moist air with an exhaust fan or other ventilation.
3. By increasing the temperature of the room: a. Add heat and the air will hold more moisture. b. Increase the room temperature and you will also increase the temperature of the wall surface.
It is usually most effective to use more than one of these methods in order to effectively control condensation.
“Original Equipment” Foam Insulation All Superior Walls products are tested to the UL1715 fire test standard and comply with the requirements of the 2003 International Residential Code - Section R314 (Foam Plastic) and Section R315 (Flame Spread and Smoke Density). No additional thermal barrier is required UNLESS additional foam insulation has been added after the panel was manufactured. Superior walls are delivered to your job site with either 1” or 2½” foam insulation installed as a part of the system. This gives the walls an R-5 or R-12.5 rating respectively.
Exterior Helpful Hints ● Grade – Slope the ground away from the home a minimum of 6 inches within the first 10 feet from the wall (additional slope may be required by your local building code). ● Gutters and Downspouts - Keep gutters and downspouts free of leaves and debris. Splash blocks or down spout extensions should be used to divert water away from the foundation.
Interior Finishing of Superior Walls • Corner Studs and Blocking – Always use preservative-treated lumber for corner studs and nailers placed against
the concrete. For areas where there will be objects fastened to the finished walls between existing studs, install appropriate wood blocking. (i.e. For curtain rods, cabinets, doorstops, or electrical and plumbing fixture locations.)
• Wiring and Plumbing – Using the pre-cast holes in the studs, install all electrical wiring and small plumbing lines according to local codes. Holes may be drilled through the top bond beam for wiring and plumbing drops.
• Drywall and Interior Finishes – After the corner studs and all blocking are in place, the Superior Walls are ready for drywall. Regular ½” drywall is recommended to span the stud spacing. It is best to leave a ½” gap between the concrete floor and the bottom of the drywall to prevent moisture absorption into the drywall. This moisture can cause

drywall deterioration and paint finish problems. Attach the drywall using 1” drywall screws. A solid bead of construction adhesive should be applied to the top bond beam and the face of the stud. The use of paneling or other similar products should still be backed with a layer of drywall.
• Exterior Holes in Superior Wall Panels – Any exterior holes that may be required for such things as sanitary soil lines, electrical service entrance cables, or chimney flues, should be made following these simple procedures: 1. Mark-out the location and size of the hole required. 2. Use a masonry hole saw or a hammer drill with a small bit (to drill a series of holes around the perimeter of the
hole). With a hammer and chisel start to work the area inside the small holes until the hole is the required size and shape.
3. After the pipe is installed, completely seal the entire area around it with a flexible sealant to prevent water penetration. A one part urethane or polyurethane is recommended. (Do not use Acytoxy-cure silicones.)
Adding Insulation to a Superior Walls Panel When adding insulation to a Superior Walls wall panel, it is important to consider two factors to ensure that water vapor does not condense within the wall cavity: 1. Controlling the moisture content of the air trapped in the cavity while adding the insulation. (It may be necessary to use a
dehumidifier.) 2. Restricting moisture-laden air from entering the cavity from the living space or from the earth beneath the wall. (This may
be accomplished through the use of vapor barriers, sealants, and spray foams. Daylight drains require a trap on the drain line to prevent a back-flow of moist air.)
The essential issue is that you must stop moisture from entering the stud cavity.
• Fiberglass batt, cellulose, Icynene®, or other materials may perform satisfactorily if the considerations noted above are properly dealt with.
There are two other methods that will consistently yield satisfactory results and prohibit condensation from forming within the wall cavity:
• Spray-on 2-part polyurethane foam. This is a closed cell material and completely closes off the cavity from moisture
penetration. It can be obtained both professionally and as a DIY kit. Several DIY kits are available on the internet. • Add extruded/expanded polystyrene foam board between the studs, and seal between the foam board and studs with
a (“great stuff-type”) canned polyurethane. The polystyrene foam board is closed cell; moisture cannot pass through, and when used in conjunction with the canned foam, completely closes off the cavity from moisture penetration. Foam board is readily available for the DIY market, as is the canned polyurethane foam.
Generally speaking, after adding any type of exposed foam insulation to the interior of a wall assembly, the building code requires that you cover the insulation with a thermal barrier to protect the insulation from fire - see your local building code for details. NOTE: This information is general in nature and may not be applicable in every situation. Your design professional (i.e. builder, architect, engineer, or supplier) can assist you in special conditions. When in doubt, please ask for guidance concerning your particular application.
