Can anyone recommend a product which would assist with the [proative] management of algae on external wooden (& other) walkways. Many of the wooden structures in our parks etc (eg footbridges) are very slippery this time of year due to algae growth. I guess wood offers potnetial alternative options for treating [say] slippery concrete, as it is capapble of being treated with(& absorbing) chemicals to deter algae growth?
Any relevant good practice out there ?

We use chicken wire on our sailing club wooden slipways. Does the trick, but not very aesthetic :-(

Wasn't treated timber used for these structures? Copper chrome arsenate (CCA otherwise known as tanalising) as used in garden decking should do the trick. I don't know if it can be applied once the wood is in use.

Eliminaation - Cordon off "out of use" signs - the most risky - replace with expanded steel.
Control - chicken wire is good eg. on landing (high risk areas of uncontrolled fall) - jetting - (algae grows again!) - sharp sand - treads on stairs can be overlayed with tough granulated material.
information - "use the handrail" signs - eg both ends of bridge.
Regard-Tom

I thought tanalising was only to preserve the timber? I have a deck & path at home (very Groundforce!) which is treacherous at this time of year.
I have to pressure wash it a few times a year to keep it grippy.

Carborundum strips can be retrofitted by routing out grooves and fitting strips of the material. This is the only reasonably permanent solution but is not cheap.

Posted By Andy Beveridge I've used slipgrip from Fibregrid with great success on wooden, metal and concrete areas. Although we leave it screwed in place, it could be lifted during the good weather (whenever that may be!) www.fibregrid.com uk company. Hope this helps.
