We have been very lucky with the dry weather so far, so progress with block work has continued at a good pace. The main pond is now three courses of block work from completion. It is now at a point where we can see the exact shape and we are really pleased with it. Spirits with the team are very high especially because the block work is perfectly level.
Rather than have a perfectly flat pond bottom we went for a six inch graduation from pond edge down to the bottom drains. In theory this should assist with waste removal and help to prevent dead spots.
Our next project is to level the garden so therefore the height / depth of the pond will be increasing by upto 16 inches based on the current ground level. This has worked out in our favour and we now estimate the overall pond depth to be looking more like six foot three inches at the edges and then down to seven foot by the bottom drains once insulation and glassing is complete.
Four two inch pressure pipe returns have been build into the pond which will ensure we maintain good water movement. The location of the skimmers has been agreed and they will at opposite ends at the widest part of the pond. You can see one in place waiting for the final courses of block work within the picture below.
The filter house also now has its first course of block work down. I have learnt is the most important course because once this is down and level the rest of the rows can be quickly put down. These blocks are being layed on their edge because they don't need to be as solid and supportive as those in the pond. This is good news because this means the walls will need less courses and therefore good fast progress next week.
