As you know, we have been awaiting the delivery of more potting material to seal the joints and hopefully get them all gas tight.
To this end, today, we headed off and received a generous donation of new potting material from Robnor Resinlab based in Swindon. They have supported our project and had already transmitted details of the innovative canal syphon application over their global intranet.
When conditions are right, preferably a fine mild winters day, we will continue the encapsulation. Hopefully this will be some time over the holiday period.
