Removal of Old Oil Spot Stain From Asphalt – Gallery

Removal of oil spot stain on asphalt, bitumen. This work shop driveway had decades of oil drips in the vehicle storage driveway area. Here we used Terminator-HSD Concrete Cleaner, so that is would show up more on the images. Over a 5 week period and four applications. Each application a week apart the stain was fully remediated. Leaving a clean unblemished area. What’s more, it’s completely safe for the water run off catchment.

Remediation of Oil From Gravel – Gallery

Onsite bioremediation of an overflow diesel spill onto gravel surface. This is the first application of Terminator-HSD gravel and soil cleaner. The product allows for on-site remediation of engine oil, diesel, petrol and hydraulic fluid from soil, and rocky surfaces. What’s more, once applied the bacteria go to work on preventing seepage into surrounding water systems.

Commercial Indoor Oil Stain Remediation – Gallery

Indoor remediation of machine oils, hydraulic fluids helps to provide a safer work environment. The images below relate to the early stages of area testing for machine that had a constant leak. Terminator-HSD manages to remediate the surrounding area and fresh oil as it leaked. Preventing the oil from seeping beyond the machine base.  Where there are decades of build up, it is expected to take mofre time. However, it will happen.

Service Station Forecourt Cleaning – Gallery

Onsite bioremediation of oil, petrol and diesel form service station forecourts. The images are over a one month period of application on high traffic areas. The remdiation process was focused on the pump base and one vehicle car width from the pump base.

Frequently Asked Questions

Our most common questions are around old stain removal, how long does it take and is it safe to handle.

There are many stain types and environmental situations where Terminator-HSD (T-HSD) will successfully bio-remediate the problem. As T-HSD is a non-chemical product is requires moisture to remain active and effective. Initially T-HSD will draw on the moisture in the stain / spill to quickly multiply the oil munching microbes. T-HSD will continue to work until the unwanted compounds are remediated.


Removing old stains?

Yes, T-HSD concrete and asphalt cleaners will fully remove old stains. However, if the stain has been caked on with layers of oil and grease etc. The top layer will need to be chipped away allowing the microbes access to the pores of the concrete.

How long does it take?

Most stains, even very old ones, are fully remediated within four to six weeks. Some hydraulic fluid stains require additional time as to fully breakdown the hydrocarbon chains.

Is it safe to handle?

T-HSD is a seaweed based product with 4 strands of bacteria (3 are proprietary) bonded to the seaweed. When the microbes are finished with their work they leave a fine sand which is easily disposed. With a net positive environmental gain. See MSDS for PPE.
