Many homeowners are looking to expand their living space by focusing underneath their homes to add a basement level as well as, or sometimes instead of, adding levels above.

In response, a number of specialist contractors have emerged who have geared up to meet the challenges presented by sub-floor excavation. As well having to get equipment to the site, spoil also needs to be removed that may comprise concrete or hard rock.  One of these contractors is Melbourne’s SLE Excavations.

"There are times when it’s not desirable or practical to use a rock hammer for the removal of hard material," SLE Excavation’s Shane Lindsay explains. "Apart from excessive noise, transmitted vibration can be an issue for adjoining residents and in meeting noise and vibration limits imposed by local councils.

"These issues were solved when we purchased a Rokla model D10 Rockwheel. We have found this extremely powerful cutting unit to be robust, reliable and versatile."

The Rockwheel enables them to significantly reduce noise when excavating rock in sensitive urban areas where even the operational hours of noise suppressed hammers may be restricted.

"The D10 Rockwheel is lighter in weight than most other twin-headers on the market. We find it can   deliver powerful performance, even when attached to a smaller excavators. We have noticed it has a high-torque hydraulic engine and picks are mounted on the drums at an angle that gives maximum power to penetrate tough material.

"We have also found the design enables picks to grip strongly and hardly ever bounce, enabling the cutting heads to rotate at a speed that achieves outstanding excavation that ensures a clean profile."

Rokla attachments are available from Semco’s sales and service centres in Sydney, Melbourne, Newcastle and Queanbeyan, as well as via Semco’s national dealer network.
