Raising the concrete wall

Two weeks ago we had to reconstruct and existing road. Along the whole road there was also an existing concrete wall that was on one part (20 meters) too low for us to be able to make a good looking road (and safe). So there was only one way to make this right: raising the concrete wall so we can raise the whole road. Unfortunately I don't have any other pictures of the road when was finished so for now I can show you just the ones on which can be seemed how we did that "project" of raising the wall =)

1st: cleaning
2nd: drilling the holes for steel reinforcement
3rd: installing steel reinforcement

Another look from the other angle =)

Then we had to install the formwork

 Unfortunately I don't have the pictures of concreting the wall so let's skip that step and go on the finish:

Finished and raised concrete wall

 

Another angle...

... and from the other side ...

... and this one for the end.

We drilled fi14 holes so we could put in fi12 steel reinforcement. The depth of holes was about 20 cm and we were installing the steel bars with a help of Sika AnchorFix-1 that is made for anchoring the steel reinforcement into the concrete (or many other materials). We used a concrete C25/30 0-16 with a hardening accelerating admixture with antifreeze affect (TKK Cementol B Novi) because the temperature at the time of concreting was a bit low. Besides, I was worried about the temperatures at night (when they got to low for a concrete to dry nice) so I didn't want to take risk.

So that's all for now ;=) Questions and comments are highly recommended. Bye!
