Hi, what can I do for you?

Cause?

External water seepage could be due to a variety of reasons including cracks on external wall, honey comb concrete, defective sealant at window, defective waterproofing membrane at roof, defective external water and drainage pipes, etc.

How to handle?

Total replacement of aged waterproofing construction is the most reliable method in dealing with roof leakage problems. The most reliable approach of solving roof water seepage problem is to replace all aging or damaged waterproof layer. Waterproofing materials commonly used in Hong Kong according to their method of construction are divided into two types: paint (liquid type) and coating (membranous type).

To tackle water seepage of the exterior wall, the first step is to replace/remove the leakage part, such as bore hole, honeycomb concrete, dust and other impurities and cracks. Next, suitable waterproofing material should be applied.

 

Legislation?

Public Health and Municipal Services Ordinance (Cap. 132)

- Food & Environmental Hygiene Department (FEHD)

Notice may be served under the ordinance for the abatement of sanitary nuisance arising from water seepage in private premises.
