Good luck. Even with the right kit diamond core drilling can be hard work. Trying to go through my garage foundations and this bad boy packed up: Still got a way to go 🙁

Thanks. Any pointers as to what that coverage criteria is? Cheers.

Any thoughts on service layout in a 9" wide trench: 20 or 25mm mains water 63mm cable duct 110mm waste I'd have said water at 750mm, electric at 600mm but where to put the 110 waste? All in pea shingle with cable tape etc.

Here's an off the wall idea, vacuum excavation. Spendy I bet but if you don't ask etc. You could be their poster girl for domestic work and get a discount! 😀 https://vacukltd.co.uk/news/everything-you-wanted-to-know-about-vacuum-excavation-but-were-afraid-to-ask/

Wrong forum! 😉

Here's an off the wall idea, vacuum excavation. Spendy I bet but if you don't ask... https://vacukltd.co.uk/news/everything-you-wanted-to-know-about-vacuum-excavation-but-were-afraid-to-ask/

Careful you don't lower or raise your garden to the point of it causing issues on the boundary. We've had walls leaning and gardens slipping on here and it gets very acrimonious.

Why no side access? Does the property go the full width? No possiblity of taking down a bit of the conservatory by that wall and going through there. It's doable narrowing through the house just slow. Cheaper than the gym mind.

Well passive submissive...

I made my daughter's staircase: https://flic.kr/p/tR4AM1

About 48hrs according to @Pocster ...

That folded back neutral, sat against the terminal... Can't get much "looser" than that. The epitome of a high resistance joint. I would have expected to see it seriously burnt and crispy. But it's not...doesn't add up. I had some MK light switches that were terrible for binding up.

But hot to trot I bet! 😉

Fixed it by fitting a non return valve where the red dot is. I need at some point to ditch the dead end mind.

I'm not sure but think there's something about an SBR mix drying quicker than a mix without? Edit: As in it's not useable for as long

Some interesting mix info here ref using SBR: "P.R. EPOXY - SBR POLYMER SYSTEM TECHNICAL DATA SHEET USES. P.R. Epoxy - SBR Polymer System is used for screeds, floor repairs, waterproof renders, waterproof fine concretes and bonding. DESCRIPTION P.R. Epoxy - SBR Polymer System has been formulated to enhance the physical and chemical properties of cement mortars and concretes. It is compatible with most forms of cement, sands and aggregates. Together with the cement, it forms a powerful adhesive to bond the aggregates together, producing a tougher, waterproof and more impact and abrasion resistant floor, repair mix, render or bonding primer. PROPERTIES The properties of the cured mix will vary depending on the type of cement, sand and aggregates used. COMPRESSION AGE. N/mm² 1 day 14 – 18 28 days 40 – 50 (Strength is dependent on mix design) PREPARATION Surfaces to which P.R. Epoxy - SBR Polymer System mixes are to be applied must be clean, strong and free from oil, grease and with a rough profile. Best preparation is with a scabbler or power washer. If metal surfaces area to be covered they must be rust free and wire brushed or grit blasted. Cement based substrates must be damped with clean water and excess water removed. A primer coat of 1:1 P.R. Epoxy - SBR Polymer System/cement is brush applied to the prepared surface. Refer to relevant standards and codes of practice. MIXING & APPLICATION Hand mix or use a forced action mixer. The components of the selected mix are measured by weight or volume and dry mixed. The P.R. Epoxy - SBR Polymer System and water is added to give the desired consistency. In an efficient mechanical mixer, mixing should continue for 2-3 minutes. When hand mixing, mix the cement, aggregate and sand dry then add sufficient of the P.R. Epoxy - SBR Polymer System/water until a homogeneous consistency is achieved. The mixed mortar is applied to the prepared and primed surface whilst the primer is still wet/tacky, using conventional screeding, rendering and concreting techniques. Apply as required on to wet or tacky primer, compact well and finish. If the primer dries, crosshatch scratch and reapply. If necessary apply mortar in multiple layers to achieve total thickness, priming between layers with P.R. Epoxy - SBR Polymer System :cement primer. STORAGE P.R. Epoxy - SBR Polymer System must be stored unopened in dry warehouse conditions between +5°C and 25°C and out of direct heat and sunlight. In these conditions P.R. Epoxy - SBR Polymer System should have a shelf life of approximately 12 months. PACKAGING P.R. Epoxy - SBR Polymer System is available in 5, 25 and 240.0litre containers. HEALTH & SAFETY There are no emissions of noxious or offensive fumes, P.R. Epoxy - SBR Polymer System is alkaline when mixed with cement and sand; do not allow prolonged contact with skin. Health & Safety information is available. OTHER INFORMATION Mix Design’s 1.

I considered sand and cement screed but in the end I did 100 mm wet concrete with A142 mesh in. Wetted with Everbuild Waterproofing additive. I levelled it using screed rails.

Buy more black stuff!

Print one in TPU.

Pooling water will find the weak point. If you can get rid of it, as the low point is "filling up", it can only help. In winter water can expand in a crack making it bigger.

A water cooler, filing cabinets and a fax machine would complete the retro look. Maybe a prominent fire exit sign too?

I see the kneeling pad's getting some use still.

You know it! 😉

Sort that crack which has the veg growing in it! Rake it out, vac / clean etc.
