How to Properly Fill a Gap Around a Copper Pipe in Brickwork?

[John9]

Hi everyone,

I recently had a plumber reroute a copper water pipe through a brick wall, and the result left a noticeable gap in the brickwork, as shown in the photo attached. I'm looking for advice on the best way to fill this gap properly.

A few details:

• The gap is fairly large in some areas, and the pipe runs close to the edges of the bricks.
• I want the repair to be sturdy and look neat, while also ensuring the copper pipe is protected from corrosion caused by direct contact with mortar or cement.

What materials and techniques would you recommend for filling this gap and blending the repair with the surrounding wall?

Thanks in advance for your help!

Hi  @John9 

Firstly  the copper pipe wont corrode touching any thing so no stress there. it will colour the same as whats there allready

You need to re lay those bricks  for starters is  the best repairs  so we  need to match your mortar colour as close as possible to your wall colour,

Try find a whole brick replacemrnt for the half brick to fully  close the wall.

Use Off White cement powder x  bag  with a bag of white sand.  Mix   1 part off white cement. to 6 parts sand add water so it is mixed in 100 % in a  tooth brush like consistancy. Color will never  be perfect.

so using gloved hand pull out those  bricks  wet the wall bricks and pulled out bricks to wet.

Now put in 10 mm thick layer of mortar at the first brick  gap including the  sides place the wet brick in place  pushing excess mortar out of the way with the brick until it is flush with the wall tap it level.

Fill the remaining hole and 2 brick spacing with mortar all round  it might on stick to the underside but  try.

Now do the top bricks only before you insert the wet bricks put mortar on the top of the bricks too.

It will be messy but try  get the bricks level with nice 10 mm mortar spacing it may take a coulpe of attempts

once all the bricks in level and flush with the wall  push extra mortar all around the bricks to fill the gaps, 

Now to approximate your Bagged brick look  wipe some more cement on to the replacement bricks if they not the original colors.

So you have a mortar covering all the bricks now .  use the  rag to wipe in some light swirl  marks to try match the  original  wall.

Wash  any excess mortar off the wall with a big sponge dripping with water to your satisfaction.  also the sponge  may aid in swirl  patterns,

the repair wont be perfect but if you  paint  later the whole thing should be blended in.
