How to fix rotting raised garden bed posts?

Hi Team

 

Our raised garden bed posts have started to rot and last night I came home to this.  

My question is what’s the best way to try and salvage what we have as a sort term fix until we can afford to complete a full renovation of our outdoor space.

Re: How to fix rotting raised garden bed posts?

Good morning @nikitacorry 

I have seen so many retaining walls deciding to have a rest day like yours. Strangely I have always sat there trying to figure out how I would do so.

First step is to actually dig out the width of a shovel blade (straight shovel) from behind the wall (Brick or timber) down to tthe same level as the ground.

Second step Is to imagine a large T (Long piece of timber and a shorter one at the end of it) lieing down with the crossbar away from you and the bottom of the T lining up with a post. 

Third step is to then dig this T shape out down by about 2 foot (say 60cm)

Once the T trench is dug the I would try bringing the wall ost back to being verticle and attaching it to the base of the T. Then back fill the T and then backfill the wall (make sure you have rocks or something porous for the first part of the backfill of the retaining wall to allow water to seep out.)

 

I have seen people suggest this way and it is the most logical way I cant think of. Once a wall has gotten to that point of relaxing  there is no easy fix. 

That said maybe a star post on the outside rammed into the ground with the timber behind it may work for a few weeks. Just to keep it out of the way. Make sure you dont spear a drian or anything with it tho.... Not that I have... lol (yes I have)

Hello @nikitacorry 

 

It's great that you've received excellent advice and a fantastic diagram from @Dave-1. Just to add to the suggestions made, I recommend using Saxon 170cm Black T Steel Fence Post on either end of the round sleepers. 

 

I propose putting the fallen pieces back into position and driving the fence posts into the ground to hold the sleepers in place. The fence post is specifically designed to be hammered into the ground with no need for a concrete base. Please keep in mind that movement will eventually occur as this is a temporary repair.

 

Here is a handy step-by-step guide:  How to build a retaining wall by @Adam_W.

 

Before you begin your retaining wall renovation, please remember to check with your local council on the rules and regulations regarding building a retaining wall in your property.

 

If you need further assistance, please let us know,

 

Eric
