Single spalled brick

onthehill

Bear with me on this folks - be prepared for some possibly stupid questions - though I've always believed that such questions are the best way to learn.

Please note that there are several related questions.

A brick at the bottom of my house - second one up from the ground - has "spalled" - I believe this is the correct word.

I think it has been caused by the blockage for a while by leaves of a channel between the edge of the patio and the wall - leaving water against the outside of the house and not allowing it to drain into the adjacent drain.

I now make sure that this never happens.

At the deepest the spalling appears to be 2cm deep but generally less than this. About 1cm or even less.

What do do?

Sika seem to do some good looking repair mortar.

This sort of stuff:

Since it has now been dry for an extensive period can I just put some of this on the spalled surface and then put some bitumen paint on top of that?

Answers on that welcome.

If that is considered not a good idea for some reason (and please say why) can the brick be replaced?

STUPID QUESTION COMING UP - ALERT.

If the brick is removed for replacement will the house move/start to fall? As it's as the bottom - though presumably the entire weight of the house doesn't rest on one brick, even though it's at the bottom (strictly second to bottom).

There I said it was a stupid question

But please answer.

Finally, if the brick has to be replaced, how big a job is this and how much is it likely to cost?


be gentle with me

The one brick can be removed fairly easily ish and replaced also fairly easily. No the whole house won't move or even start to fall.
Its the cost of a brick, some mortar and someone's time. The time will cost more than the brick and mortar.
Eta strictly the brick may seem to be 2nd row up, but there are hopefully several more below as there is usually foundations.
Dunno bout your other questions though.

Eta2 just googled how long to replace a brick. It tells me 1 to 2 hours
