Pool restoration pt 4

The next step was the epoxy injection.
Basically this is a two part foam which needed to be injected into the cracks, where it would expand into there to fill any deep spaces and fill/prevent any leaks.
The way it works is you cover the surface with a surface seal epoxy, and attach injection ports every so often;

These are the places to inject the foam, so its important to block/seal the rest of the crack and be sure the foam will fill/flow inside.
Also interesting to note how the stale’s epoxy has changed color over the last week as it cured;

Lots of ports mounted, I did this for all the cracks in the pool surface as well as the split at the bondbeam;

Then I injected the foam itself,

I used three kits and did it in several passes,

The foam/epoxy made a big mess, but I think it got everywhere it needed to be (and then some)
This was in the middle of applications, as you can see the top near the bondbeam needed a bit of patching;

More injections!

I also started doing some testing with hydraulic cement; patching over the exterior of minor cosmetic scratches, in gaps near the bond beam, and on exposed gunnite.

After the foam had cured for a week or so, I started removign the ports as well as the surface seal;, first pulling the ports and chipping away large chunks;

This is what I wore while doing that, feeling like a sci-fi character

Then hitting it with the grinder to knock back more of it, and leave a sort of ‘keystone’ shape and roughed up surface so that the plaster/cement over top the epoxy wouldn’t be able to pop/shear off.

It seems like everything near the pool has become covered in dust from the grinding, bit it was starting to look a lot better!
Untitled by bradisdrab, on Flickr
This took way longer than I expected/planned, I’ve now officially lost track of how many bucket loads of debris I’ve carried out of here
Untitled by bradisdrab, on Flickr
I knew better than to do too thick a coat of the hydraulic cement, its more there to provide a non-shrinking plug and seal, rather than structural strength, so I tried to keep it around 1/8 inch, and wet the surrounding area to prevent it drying unevenly
Untitled by bradisdrab, on Flickr
I couldn’t stand thinking of looking at the epoxy for another week, so I worked well into the night, patching and coating it with hydraulic cement.
Untitled by bradisdrab, on Flickr
Ended up using three buckets, about 30lbs of hydraulic cement
Untitled by bradisdrab, on Flickr
Its come a long way!

In case anyone is reading along for knowledge, I should re-state; I’m not a professional, I’m just learning as I go, and doing my research online as well as speaking to a few pool guys while gathering info/estimates…
So I’d left off I here;
Untitled by bradisdrab, on Flickr
Hydraulic cement patch/seal over the cracks and epoxy/foam. I figure the thinness of the cement will futther seep into the cracks and seal it more, and I made sure to leave a rough texture, so that the next layers would have something to grip.
Looking at the surface I started to notice a bit of discoloration;
Untitled by bradisdrab, on Flickr
A bit of a yellowish tint and some hairline cracking in there;
Untitled by bradisdrab, on Flickr
NOT GOOD.
I knew the hydraulic cement wouldn’t be structural, but this isn’t right, and as soon as I started tapping it with the mallet/chisel I could see what was happening as it sheared off and crumbled;
Untitled by bradisdrab, on Flickr
I’ve never heard of this happening before, but the yellow seemed to be oils leached out of the sealing epoxy, which weakened the hydraulic cement, as well as the cement did not bond to the leftover epoxy much at all, so I set about knocking off all the problem spots to grind down the epoxy even more.
Untitled by bradisdrab, on Flickr
Very discouraging, but I kept at it, removing the bad material and going back down to get the surface epoxy off too. Very discouraging, but I keep telling myself, its better to go through this now then later when its filled with water…
Next I repacked it with a portland/sand mix, which should prove to be a lot stronger, and with the epoxy residue ground away it should provide a much stronger patch;
Untitled by bradisdrab, on Flickr
I left the texture pretty rough so the replaster would have something to grip.
Untitled by bradisdrab, on Flickr
Already feeling a bit better about this, and the portland/sand mix is pretty close to what I’ve been thinking of plastering the whole pool with, so I can see how dark it would end up being, also note the root that’d been hiding under the old deck, no wonder this was beginning to crack!;

Now that the plaster was clean, the weak parts removed and cracks exposed I was ready to deal with them. I ordered a few different kits of materials; staples and epoxy.
I went with two kinds of staples, basically to reinforce the areas that I was worried may be weak and eventually crack again.
Carbon fiber from Leaktools

Steel from Torquelock – these ones interest me the most since they are engineered to apply pressure to the crack in addition to holding it.
Untitled by bradisdrab, on Flickr
I planned these out where I thought they could do the most good;

Masonry cutting disks in my angle grinder worked well for the countersink, but after drilling for a solid day and having my hands go numb I realized why a regular drill even with a good masonry bit is not the best way,
Untitled by bradisdrab, on Flickr
So I ran to Harbor freight and picked up a rotary hammer drill, which was AMAZING, so much better! Made the rest of the drilling a breeze in comparison. It was like the difference between when I was chiseling by hand vs when I got the air chisel.
Untitled by bradisdrab, on Flickr
A lot of staples… just cutting, drilling, and plotting them all out first;
Untitled by bradisdrab, on Flickr
Might have been overkill for some places, but figured its better that way, than not doing a spot and having that be where it re-cracks;
Untitled by bradisdrab, on Flickr
The staples were set with a special epoxy;
Untitled by bradisdrab, on Flickr
Starting with all the carbon fiber ones;
Untitled by bradisdrab, on Flickr
Then the steel ones, the epoxy is harder to see since its just on the inside, but it was applied to the posts and face surface, then pressed into place. After that I twisted the cam to apply more pressure by drawing the posts closer together;

Once we got the old tiles knocked off and a couple rounds of pressure washing in it was time to see hom much cleaner it’d get by acid etching the surface.
Here I’ve started the acid wash,
I was just doing it by hand, using a spray bottle and scrub-broom,
this was after the first gallon;
Untitled by bradisdrab, on Flickr
halfway done;
Untitled by bradisdrab, on Flickr
after etching through the dark/black stains I could see more to do, and I found the Anthony Pools tile;
Untitled by bradisdrab, on Flickr
It was in doing the second half that I figured out a better way of applying the acid; using a super soaker!
Untitled by bradisdrab, on Flickr
After acid washing the whole thing, and continuing to remove old/bad/delaminated plaster, basically anything that sounded hollow, was stained/softer than the rest;

Pool restoration, pt1
When I bought my house back in March, I knew it was a foreclosed fixer-upper and there were a lot of things that had deteriorated after years of neglect, but I’m a sculptor at heart, have worked in construction before, and love getting my hands dirty.
In the listings the pool looked like this;
Untitled by bradisdrab, on Flickr
either the previous owner started, or the leak drained it partway, because when I got to it it looked like this;
GOPR1748 by bradisdrab, on Flickr
Note the giant tree, which I suspect was the cause of the cracks;
GOPR1595 by bradisdrab, on Flickr
That and years of bad chemestry had left the plaster in pretty bad shape, a lot of bad staining, and softened corroded areas, especially around the cracks. The areas of blue/green aren’t paint, it was just eaten from the old/bad chemestry I think. That discolored plaster was softer and crumbly.;
Untitled by bradisdrab, on Flickr
So the first thing was the tree, it had to come out;
Untitled by bradisdrab, on Flickr

Sad to see such a cool old tree go, but there was no point to restoring the pool if the tree was just going to continue breaking it up.
I drained it, knocked out the old tiles, and got a better look at the damage. About half the coping had seperated from the bond beam, and some of the cracks went pretty deep, through the gunnite,
Untitled by bradisdrab, on Flickr
Then a couple rounds of pressure washing, my fiance got in on the action as well;
Untitled by bradisdrab, on Flickr
I’d started by hand, but got an air-chisel to chip out the old/bad/delaminated plaster, and open the areas around the cracks;
Untitled by bradisdrab, on Flickr
It took a few solid days to chip out;
Untitled by bradisdrab, on Flickr
After the worst of the plaster was removed and a couple rounds of pressure washing it looked like this;
Untitled by bradisdrab, on Flickr
But I could see that simple patching wasn’t going to cut it, a couple of the crack were pretty bad;
Untitled by bradisdrab, on Flickr
I’d come up with a plan to fix the cracks, but first I needed to finish preparing the rest.
