Treated Wood Retaining Wall

Hello everyone, I am a Scout is about to make life a retaining wall to prevent further pollution of the stream caused by soil erosion and I was wondering the benefits of a wood retaining wall as park, I am associated with has asked me to build the wall using pressure-treated wood against the concrete. Are there advantages to using wood?

Yes, the fact that you can provide the wood for the construction much easier than having concrete delivered or carrying bags of ready-mixed concrete work area.
Woods is also in the park setting is a better product more natural compared to concrete.
You might mention that the wood contains chemicals that can leach into the stream - I bet they have not thought about that. If you build a retaining wall made of wood, I lean back into the slope and put your uprights every 4 'buried 4' in the ground and lean back into the slope about 10 degrees. For added strength to a dead man "on each vertical post. It is a steel cable to the highest point on the earth covered with a vertical strain of post buried about 4 feet long. earth fill above the wood Deadman and cable. The dirt keeps the pressure on the buried piece of mail that should pull up and off the field before the vertical position, it is attached, can move.
good project.

Concrete lasts forever. Pressure treated wood

Wood is better at first, but it will not last. pressure-treated wood should be re-processed every time he cuts (The treatment is only outside, cutting it exposes the inner untreated.) Also, the treatment of pressure causes the fastener (nails, bolts, etc. to have a chemical reaction and may damage them. You end up having to use stainless steel or other high quality fasteners to prevent it. Wood is cheaper, but it will not last nearly as long.

If the park really wants to fetch wood, you can go with a plastic wood composite (as Trex), which looks like wood but does not degrade the chemicals, or treated lumber does.

Hope that helps! Good luck. Is this your project eagle?

Concrete should be digging for a foundation that would be big enough for a wall much heavier than a timber .. the wooden wall, should you dig deep, but only the post will be .. reinforced concrete, it would bar and building forms for concrete .. timber should not require that. consider what you would possibly try to remember, and then if your number is going to need a dam, or whether something less will suffice.

It depends on how long you want it to last .. Concrete will last longer than the .. wood, but ugly and against nature .. But this is not true that if you cut wood tannilised he will need in retirement .. tanilised green (light in True Colours) .. will last at least twenty years under all conditions for wood .. tannilised you put in a sealed .. remove all the air in a vacuum .. then introduce chemicals .... This way, you get total saturation ... its use in the United Kingdom for most jobs fences etc.
