This is to confirm that the above Company worked together with us on a fuel storage compound in Koniambo, New Caledonia, 2012.

They assisted us in fault finding and re-instating a failed diesel storage facility.

This consisted of designing a new lining system and required using innovative lining techniques to complete the project.

They worked in a professional manner and integrated well with the local crew, despite the language barrier. They showed good health and safety practices and the work was completed to a high standard.

Should you require any further information, please do not hesitate to contact me.

This is to confirm that GR Environmental Lining Services Ltd worked for us on a fuel storage compound in Port Moresby, PNG, 2017.

The work involved, included an under tank “Leak Detection System”. The compound and bund areas were completely lined in HDPE to meet our specifications.

I found the expertise and services of the crew involved to be of a very high standard. They showed excellent knowledge and understanding of works to be undertaken, materials used and always acted in a professional manner.

Should you require any further information, please do not hesitate to contact me.

Hikurangi Forest Farms Ltd – Gisborne

Hi, my name is Warren Payne and I am a Forest Operations Coordinator with Hikurangi Forest Farms Ltd a Forestry Company in Gisborne New Zealand.

Over the last Fifteen years I have installed many Lined Fire Water Reservoirs within our Forest Estate. In 1998 GR Environmental Lining Services supplied and installed onsite our first HDPE Lined Fire Water Reservoir. Previous to this we had used Butanol Rubber and other products that were manufactured in a factory then transported onsite and installed. These were cumbersome labour intensive and generally not that great.

GR Environmental Lining Services were a revelation and in the past 11 years we have gone on to install 20 Lined Fire Water Reservoirs holding on average one Million liters each. At times they are asked to work in challenging situations where access and the weather has not been that great. They are prompt, helpful and deliver a good service and product.

I would recommend Graham and his team along with their product for any lining requirements.
