STACKWALL SEISMIC LOAD RATING

Seismic Rating Seal

Seismic Load Rating Overview

StackWall is engineered to stay upright & safe in a California earthquake. Even if the ground shakes, your wall won't.

How StackWaII Performs Under Seismic Loads

  • Designed to Meet All Seismic Categories:
    Calculations are based on typical California soil conditions (calculations will vary depending on location). StackWall can meet code requirements for all Seismic Design Categories for residential & commercial.
  • Engineered for Earthquake Forces:
    Withstood lateral seismic loads up to 1.892 kips with minimal deflection (only -0.16 inches).
    This level of force is similar to what you'd see in a strong California quake (around Magnitude 6.5 to 7.0) depending on the location & soil. StackWall is designed to withstand this kind of intense shaking.
  • Strong Foundation System:
    StackWaIl uses deep, reinforced footings designed to resist sliding, overturning, & uplift.
  • Code-Compliant Across California:
    Meets or exceeds seismic requirements under the California Building Code (CBC 2022) & IBC standards.

Seismic Load Ratings Overview for Exterior Walls

SEISMIC DESIGN CATEGORY SEISMIC RISK LEVEL TYPICAL USE CASE WALL REQUIREMENTS
A Very Low Areas with minimal seismic risk Basic wall design; little or no seismic detailing
B Low Light residential zones Minor reinforcement; standard footings
C Moderate General U.S. building zones Requires lateral load analysis
D High Most of California Reinforced design; deep footings; engineered system
E / F very High / Special Soils Near major fault zones, soft soil Specialized structural design; strict oversight
