Mike Kushy, solo. Took in a bag of postcrete, bung with tap attachment and hose. Dismantled some of the dam and built it back up using the postcrete. Once this was finished I went to the dig face with some empty buckets to grab some sticky mud and give the postcrete time to set. Big puddle at the bottom! (Glad I didn't struggle bringing the drill in). The sticky mud was used to line the dam inside and out. Once this was done I fitted the bung into the pipe work and attached the hose. Need to render the dam up with cement ideally at some stage as there are still a couple of minor leaks. The hose was really effective and a good flow came out, enough that the dam doesn't fill up quick enough, to provide a constant flow. I've left the tap open and managed to put the hose into the boulders to the left. Turned the tap off for a while and then opened again. The water can be heard flowing off down the hose and into the diversion. Recommend leaving the tap open open when not there, then closing on arrival of digging trips ready to use for cleaning or flushing afterwards. 2 hours. Mike.

Mike Kushy, Sam Hill, Mike Wise and Kaz Noiri underground around 1845. Kushy found Kaz at the Wessex and Kaz wanted to see a Mendip dig. After an induction by Sam on what needed moving and what shouldn't be prodded, Kaz moved mud and rocks away from the face to the bucket loading area. Mike W dismantled the dam and rebuilt it to accommodate the 4" pipe and Sam and Mike K tidied up the dumping area before hauling up and dumping some of the filled buckets. Some buckets of nice sticky mud were used in the dam construction.  Some rocks were dismantled using P&F before being hauled out. After clearing up the dig face, Kax experienced an unexpected  (to him perhaps) aspect of digging when the forward part of the left wall collapsed.  This is visible in Sam's second photo.  A great time was had by all. Time down 2.5 hours. Some rocks at the bottom need reducing for hauling out. The dam is higher than previously and the inside of the dam base needs sealing around the pipe. Suggest a pea or smaller gravel concrete mix. It will cure underwater, although if anyone has any 30-minute curing cement, that would be good. Mike Wise.

I left the guys at the 2nd connection to the Boulder Rift Chamber and headed to Tooth Dig. After the initial squeeze down you can traverse straight across to the loop, rather than all the way down and back up. Now with a view to the hauling spot I started clearing the gloop further back. Sam showed up and  started pushing rocks and gloop back to me. Enough space was made to be able to slide small buckets through. Lots of clearing of the hauling spot and spoil from below. Recommend always doing it this way rather than blocking the way again. I then went down to join the others. Kaz and I left out of the old cave exit. Mike Kushy.
