From the manhole 600mm pipe rocker I installed into the rear garden manhole I clean and grease the rubber collar to a 100mm, 33 degree bend coulping sleeve and slide cleanly the sleeve over the pipe.
From the bend the appropriate length pipe work is install on sand to the appropriate falls to the base of the bespoke overflow system channel.
You see from above that all cut pipework for the landscaping pond overflow system must be chamfered with a file to 45 degrees, should a pipe be inserted into any collar with out the chamfer or grease the rubber is likely to fail on your pipe test and not hold the required air tight seal.
On the concrete footings two parallel courses of brick work form my over flow channel from the slightly falling natural roofing slate reflection pond slot, I then bench the inside of the channel and allow to set for the day
Marshalls reflection pond
The Marshalls landscaping garden refection pond is built from 225mm 7N concrete block to the required height of 70mm below FFL, finish floor level, allowing 50mm full mortar bed and 22mm Marshalls fairstone caramel cream paving unit.
Marshalls bullnose speaker ledge
Using the end caps to Marshalls fairstone bullnose steps I have created a simple, yet effective, garden walling ledge
Reflection pond over flow
The interior to the pond overflow channel is rubbed with a sponge to create a seal and smooth free flowing water channel, I will later install a durable cap
