Preparation

• Check the wall closely before making the decision to remove it if this is more than a cosmetic issue. Small cracks and a little amount of ground sinking and frost heave can be repaired. However, it is when these issues develop into large problems that the need for removal and destruction becomes necessary. Prior to beginning the removal, it is necessary to contact utility companies, such as gas, electricity, telephone, water and cable, in case of obstructing or buried wires or cables.
  
  

Demolition Permit

• Whenever a structure is demolished, regardless of the size, generally local building codes require a permit for the destruction. Check with your regional governmental office for any required permits. These are generally needed to keep the public apprised of any construction zone areas to monitor safety issues. There usually is a small fee for the permit and may be some additional charges in connection with the utilities.
  
  

Removal Methods

• If you are attempting to break up a small wall constructed of concrete block and mortar and do not wish to save the block, a chisel and sledge hammer may be all the method you need. However, if you are tackling something a little more complex, contacting a professional is recommended because most methods include using types of heavy equipment. Removal methods for concrete walls and other structures are classified as crushing, impacting, blasting, cutting, pre-splitting or milling. This is not a job for the amateur.
  
  

Tools

• Some of the tools that are used when removing concrete walls are classified as heavy construction equipment to be operated by trained professionals. A number of different hammers are utilized, such as a pneumatic, rotary, demolition, hydraulic and chipping. Of these, the chipping hammer comes in sizes that weigh from 5 to 30 lbs. Other tools that may be used include a hydraulic splitter, hydraulic concrete crusher, pavement breaker and a diamond wire saw. Again, demolition of concrete on a larger scale is better left to the professionals.
