I recommend a multi-layered approach to foundation waterproofing for Bali villas and hotels. Start with a heavy-duty HDPE geomembrane under the slab, add crystalline admixtures to the concrete, and seal exterior walls with a cementitious membrane such as SikaTop-107. Also install a damp-proof course and PVC waterstops at joints, and include sub-soil drainage around the perimeter to manage the high water table.
These steps reduce rising damp, prevent concrete corrosion, and minimise mould risk — protecting both structure and guest health. If you’re investing in Bali or Ubud, I can help integrate these measures into your project plan, coordinate materials and contractors, and ensure quality control through to handover.

In Bali, waterproofing your villa's foundation isn't just a "good idea"—it is a structural necessity. The island’s high water table, porous volcanic soil, and intense monsoon seasons create a constant threat of rising damp and hydrostatic pressure.1. Why Waterproofing is Critical in Bali • Ris...
