Algae growth - 0n a new retaining wall

[davowolf]

After only three months I've got green algae on my new wall. I've tried to post pictures but 'it' tells me I can't.

This is a new web site I signed up for just to post these pictures here! Here is the link to the site...

Hope you can see the pictures under 'Home Building'.

If anyone can suggest how I can get these pictures up on here I'd be most grateful. And yes I've read the Intro section in Brew Cabin but there's clearly something I don't understand .... both about posting pictures and why I've got green algae.

Any suggestions ?

Nice Bike Davo and nice wall also.

Algae just likes to live where conditions are damp and in the shade.
Diluted bleach will get rid of it for a time.

Hi peter they certainly nailed it in the end
the reason you have that is that there isnt a drip on the sailor course
not a problem per se just the water finds the easiest route

how long did it take them
where are the weepholes? couldnt see them

lovely job though

Thanks for the K-Rend link - I'll get some. My worst fear was/is that after careful design of the retaining wall with all the right things water was still getting through like the old one it replaced.

And yes, those weep-holes are there actually. The builders used oval white plastic electrical conduit pipe about every three bricks. If you look careful at the pictures you can just make out a couple of them.

If the weep hole length is not at an angle through the wall they won't work no matter how good all the other back of wall stuff is. That's my fear with this algae thing. But I'd have preferred copper piping or larger diameter weep holes in retrospect.

How long did it take ? About 7 weeks but the bricklayer did work very 'carefully' and had never attempted the flint work before.
