Tie Down ABS Pad User Manual

ABS Foundation Pads
by TIE DOWN ENGINEERING

• Lighter than concrete,
saves on labor.

• Larger pads to increase spacing,
saving time and material.

• Made from recycled materials.

• Easily stackable for larger pad
area and wider pier spacing.

• Multi stack for 5 sq. ft. & 6 sq. ft.

ABS Foundation Pad Installation Instructions

1. Pier spacing must be in accordance with the
Manufacturers Installation Manual and/or
State or local requirements.

2. Clear all vegetation and debris from area
where pads are to be placed.

3. The ground under the pads must be leveled
and evenly compacted or undisturbed soil.

4. Determine pad size by testing for the soil
bearing capacity, if soil testing not available,
use the 1000 PSF soil column of
the instructions.

5. Place ABS pad with grid side up, smooth side
down. Center blocks or pier on pad and
complete Installation.

General Notes:

1. Any configuration from the chart may be used
to replace a concrete or wood base pad per

3282.312(A)(3).

2. The maximum load at any intermediate soil
value may be interpolated between the next
lower and next higher soil values given in the
pad bearing capacity chart.

3. Pad sizes are shown in nominal dimensions
and may vary slightly.

4. Maximum deflection 3/8”, measured from the
highest point to the lowest point of the top
side of pad.

5. In areas susceptible to frost heave, the pad
must be at the frost line or otherwise
protected from the effects of frost. Refer to
NCSBCS/ANSI A225.1 “Manufactured Home
Installations” Homes set to Standard
24 CFR 3285 should not be susceptible to
frost heave.
