Have a water leakage problem with a wall shared with a neighbour in a landed double-storey link property .


Houses in the row are 20 years old and have air wells originally, exposing the space to the rain and heat.


I have covered mine up and made it an extended part of the dining area. But noticed the wall was leaking.....damp after a rainfall. Plaster ceiling was partly spoiled by the leakage.

My new water pipes in the wall were not leaking. My contractor traced it to my neighbours's airwell which is uncovered.....so when rain comes and pools on his side of the wall, it seeps into my side and travels upwards.


Contractor has done his best to go over to their side of the wall, clear the drainage hole and try to "waterproof" and seal cracks as much as possible, saying if it works, it may only last 2-3 years.....I need a permanent solution otherwise my paintwork and plaster ceiling will be spoiled again with dark spots indicating fungal growth.


Will be calling up waterproof specialist JS Star Construction for advice. BTW, has anyone use this JS Star before (apparently named after business owner Jacob Soon), and how is his work? Another company I was referred to was GreenSeal (https://www.greenseal.com.my/). Anyone with experience with both companies, pls share your experience before I hired anyone of them to do the job.
