Hi,
Thanks Barry; I'm confident I've put the problem to bed once and for all; it's not the kind of work I enjoy but I never ever take the easy option. I've found a few of the pictures and also a few pictures of drain repairs I carried out. Whenever I do anything I always think back to my apprentice days where I was taught to think for myself never accepting anything just because its been done a certain way for 100 years; take it back to basics and see if it can be improved upon; I applied this to both the garage water ingress and the drain repairs dreaming up new ideas. The use of perforated plastic conduit placed in the wall cavity bottom is my idea and should any water enter the cavity it will discharge harmlessly onto our driveway.
The drain repairs are to the rear of our bungalow; we were fed up of the open drain hoppers collecting debris and slugs also they tended to smell. The old drains were the heavy clay ware kind. Applying a lot of thought I came up with the idea of disposing of both hoppers and install a sealed system as seen below in the pictures; inside the bungalow we have an automatic vent to the 4" dia soil pipe.
Both these jobs were hard graft; the garage floor slopes so this caused bricklaying problems; I ended up buying a diamond disk for my big angle grinder allowing me to slice through the dense engineering bricks. I'm not smart or clever I was just taught by top engineers whom I owe so much to.
Later we suffered water ingress under the bungalow and I cured this the hard way installing underground flood defences which proved to be another big job; for this I bought a brand new cement mixer; kept the mixer for six weeks then sold it on after completing the work only losing about £30 making it much cheaper and more convenient than hiring which I never do.
Hope it's of interest.
Kind regards, Colin.
New drain by rear door.
Both new drains fully sealed; kitchen outlets into single drain; much better than the original open smelly drains. I laid the big paving flags when I retired; leaving a wide mortar joint allows individual flags to be lifted if ever needed. It pays to give a great deal of thought to any job trying to improve for the better.
It's not difficult to improve on this but requires quite a bit of thought coming up with new ideas. Definitely not a job for a novice to tackle it could prove hugely expensive if it went wrong.
New into old; please note old clay pipe end removed with angle grinder and new black rubber coupler. Pipe end sealed during work using old towel to prevent debris entering and blocking it.
The old hopper by the rear door designed to collect lots of smelly debris and slugs.
Garage water ingress work under way to resolve it. Please note bricks left in place to support the wall; these were removed once the new engineering bricks were in place and had a couple of days for the mortar to harden; waterproof mortar was used.
Engineering bricks going in; please note end of white plastic conduit to cavity bottom this leading to the driveway. The 15mm copper discharge pipe connected to the conduit still remains dry; it's a job I only ever want to do once.
Removing more bricks at a time would be asking for trouble.
Resorting to solid dense engineering bricks needing cutting to accommodate floor slope. New DPC also going in.
It doesn't take much to improve on this sorry state of affairs. I hadn't realized how bad it was until I pulled the benches away from the wall. The bricks were absolutely saturated being porous.
