Concrete Block Foundation Earthquake Resistent

It is a must that your concrete block foundation be earthquake resistant because observations on the performance of buildings during dangerous earthquakes have proved to be a time tested method of educating builders on proper and improper construction methods. To help fix this problem there are earthquake load resisting systems . The damaging potential of strong earthquakes is well known and is accepted as the underlying foundation by most design codes.

The main deficiency of the widely used concrete buildings is their inability to resist lateral earthquake forces. Beam-column joints fail usually at the first storey column level. This is due to their inability to sustain high stresses the joints were subjected to during an earthquake.

A concrete block foundation must have rebar (reinforcing bar) laid both horizontally (up and down the walls) and vertically (along the walls) so that the structure is well grounded. Special blocks commonly known bond beam blocks are placed every few courses to allow the rebar to run the length of the foundation. The goal is to maintain the foundation in one piece in the event of an earthquake. Once properly placed and all the proper rebar is run up and along the foundation, you will have a permanent, cost effective block foundation that is fully earthquake proof.

Note: Adding rebar to concrete blocks is an effective, time-tested method. However, it can be tricky. If you are a concrete novice, it is highly recommended to consult with a licensed contractor who has experience pouring this type of foundation. It will save you time and money, and you will definitely learn something.

Key Benefits of making your block foundation earthquake proof:

• Strengthen your Home or Building

• Prevents injury

• Economical

• Adds Value

• Add safety and piece of mind
