If they do then shipping costs would be horrendous.

Well after much procrastination, pontification, deliberation and hesitation and then running out of more important jobs I finally made a start this morning.

After less than 1 hour with the SDS drill and a few thumps with the hammer and bolster. The SDS is the way to go far less mess and less risk of flying debris. Oh and I wore goggles throughtout :D

The grey stuff is the glue. A whole chunk of glue and concrete is about to come away from that uppermost riser.

If the rest come up so easily I will be very happy, if not a little surprised.

Good job - I love that kind of DIY demolition. If I had done what you have, SWMBO would have strung me up for not moving the plants though!

It helps to sharpen the chisel periodically with a grinder as it will tend to skid off less easily.

The proper scraper attachments take it a step further, but they're ridiculously expensive for what they are. I made my own version in five minutes from a spare breaker steel, a £2 floor scraper blade from eBay and a couple of bolts. It's not pretty, but works well for a bodge.

Thanks Mark. I am not that confident that my Ryobi SDS drill will survive the whole terrace. I may have to buy a dedicated breaker, your scraper looks doable.

If you do buy a dedicated breaker...or one that has drill/hammer+ drill/hammer make sure you get one with reverse. DAMHIKT

Progress. A third of the way there.

A fair few of the tiles are coming up whole or in just one or two pieces. Very satisfying when they lift up with a slight "pop".

Neighbour came over this afternoon and has offered to take away all the old tiles to put down on a property he owns down on the marshes near here. It floods every year so they are constantly looking for hardcore for hard standing.

Just caught up with this thread.

I recognise that old terrace! 8-)

Good work Andy! I bet that's hard going on the back, but well done that man! 8-)

I hope you're rewarding yourself with a lovely cold beer after each session.

Thanks Paul,
I only manage about an hour at a time. Knees are the biggest problem even with knee pads.

Cold beer :o :shock: I'm a room temperature real ale man. :) . I'll have one on Friday to drown the sorrows after what I expect will be a loss to the Netherlands.

If the weather holds should have it finished before Easter.
cheers

Ah yes, after I wrote 'back', I meant knees. :eusa-doh:

A lovely cold Carling Black Label would do the trick. :P

That's a big old terrace.

I think not. These two images show the worst area.

We are having the builder back to re-assess now the bulk of the times are off. My gut feel is that at a vast chunk of the top layer of concrete needs to be replaced perhaps even re-enforced.

Yes and no Roger. It had to be done. I am not at all sure whether the builder was expecting the base to be so bad. Will see next week.

The highest part and the only bit not to have sunk is built above a cave* and I cannot gauge how thick the roof is.

* That's french for wine cellar not an hermit's home :)

Terrace is is now clear of tiles so I moved on to the the steps.

From about the second step down a steady trickle of water oozed out from, I guess, between and around the concrete breeze blocks. These tiles were also far better stuck then any on the terrace.

A lot of the tiles had a build up of stains along the grout joints from what I now realise is water seepage.

Something else to talk to the build about next week. What is the recommended method for sealing steps like these to prevent water ingress between and eventually through the tiles?

Re: Removing tiles from terrace -finished but water problem.

Postby Mike G » 23 Mar 2018, 18:02

Where are the steps, and what is their relationship to the patio?

I'd assume that the water is groundwater, and that the steps are acting as a retaining wall. There are only two good approaches: formalise the route through the steps for the water, or put in a drain behind the steps to take the water away. Relying on the tiles, or the steps, to hold back the water isn't a long term plan.

the top of the steps are to the right of this image.

The second, untiled terrace surrounded by the green fence is about to be resurfaced with 100mm of reinforced concrete and the dwarf wall just visible behind the water butt will be extended around to the top of the steps.

A view from half way up the drive. Steps to the left, main tiled terrace is behind the house away to the right. That wall is a little over 6 foot high.

The last image shows where the wall to the left of the steps will be extended to the left to meet the boundary fence. Exiting and new walls to be rendered to match the house.

Hmmm. I can see a little digging in your future. If you were to run a land drain around from the back of the steps to the bank to the left of them, in the last photo, that should solve the problem.

Groundwater pressure behind a retaining wall or abutment can be quite considerable and to relieve this, a layer of free draining material or porous blockwork is usually constructed behind together with small diameter weep pipes exiting to the front face. This prevents any build up of water behind the back if the wall.

Rod, thanks. That gives me something to discuss further with the builder next week

Thanks Mike,
That bank is going to be walled in so I guess a combination of drain from behind the steps and weep pipes as suggested by Rod are in order. I wonder if 55m2 of broken tiles would surffice for the porous layer behind the wall?
Again I will see what the builder proposes next week.
