We also have useful downloads available to assist you in the design of stockbay walls and inspecting existing walls.

Important Information

• Wind loading can affect stability of single-skin walls above 4.05m.
• Avoid direct impacts between mobile plants and block walls.
• Strapping top layers can mitigate risks in high-impact areas.
• It is the customer’s responsibility to ensure appropriate structural checks are performed before installation of any precast concrete products.

1. These loading figures are for guidance only – if in doubt consult a structural engineer.
2 The retained material should be allowed to naturally fall against the wall as it is stacked.
3 These loading tables relate to specific materials with a typical density and angle of repose, stacked to specific heights and slopes.
4 The client should ensure that the walls are built on a suitable base.
5 The density and angle of repose of each material shown are typical values only.
