Patching a concrete wall.
Hello all,
I have a small leak in the concrete wall in the cellar. The rain is making it a bit of nuisance. I have tried to fix the issue by finding the hole, drilling it out and filling with some silicone sealant (done when there was no rain and no water ingress). This, surprisingly, worked to some extent, but water (as it does) finds its way in. I suspect that the drilled hole wasn't as clean or dry as was necessary for the sealant to work properly. I am now thinking that perhaps a larger hole should be drilled and filled with a cement mix. Is this in principle something that could work? I know nothing about cement / concrete, hence my query. Does new cement bond with old cement to form a watertight seal, or will another product have to be used? Or an additive in the cement / mortar. Thank you in advance for any help, David Paste. |
