EXCAVATION
Excavation Techniques
Depending on the specific project requirements Codmah can employ’s either one or both of its two excavation methods;
- Excavators inc backhoes
- Trenchers inc large Rock Trenchers
Excavators
Codmah have at its disposal a range of excavators (5 to 25 t) that can be selected to meet the individual construction demands.
Our excavators offer flexibility by the range of attachments that can be fitted, including;
- Different bucket types inc
- Rock hammer
- Rock saw
Benefits of excavators include;
- Compact design allowing flexibility in tight / confined worksites (inc inner city)
- Attachment / bucket changes are quickly completed
- Can be utilized to lift, position & lower pipe strings into trenches
- Ability to rotate boom / cabin within track area
- Rubber padded tracks for inner city operations
Trenchers
Codmah have a comprehensive selection of trenchers including units that can be used for placing small diameter pipelines into private properties or rock trenchers that will allow large diameter pipelines to be laid through residential (city - rural) and or industrial / commercial areas.
Our large Vermeer Rock trenchers offer the unique benefit of being able to cut trenches of various widths because the chain & boom assembly can be changed.
Benefits of trenchers include;
- Greater trench depth & width accuracy
- Trenches can be opened more quickly when compared to an excavator
- Easily mobilized within tight residential areas
- Opening trenches in bitumen roadways without the need for saw cutting
- Spoil removal via either ground level side exit or a above ground conveyor belt system to the rear of the unit
