Domestic waterproofing is the process of applying specialised, water-resistant barriers to specific sections of a home to prevent water from penetrating structural elements.
In residential construction, water damage is one of the leading causes of structural degradation, toxic mold growth, and expensive renovation bills. Proper waterproofing ensures that water is safely directed down the drain rather than seeping into building materials like timber framework, plasterboard, or concrete slabs.
