Waterproofing services by Wilcon Utama Indonesia

What Is Waterproofing?

Waterproofing is the process of applying a watertight coating to a concrete structure's surface to prevent water from seeping in. Without proper protection, water can damage the building structure, trigger corrosion of steel reinforcement, cause moss and mold, and disrupt your factory or warehouse operations.

Wilcon Utama Indonesia handles waterproofing using genuine Sika products selected to fit each area's characteristics — both for horizontal surfaces like factory roofs and vertical surfaces like ground tank walls.

When Do You Need Waterproofing Services?

  • Factory or warehouse concrete roofs starting to leak or showing seepage signs
  • Damp production facility basements from groundwater seepage
  • Factory ground tanks or water reservoirs that need to stay watertight
  • Wet production areas that need a long-lasting watertight layer
  • Retaining walls in warehouse areas
  • New factory buildings wanting to prevent leak problems from the start

Application Areas

Factory & Warehouse Roofs Production Facility Basements Ground Tanks Wet Production Areas Gutters & Hard-to-Reach Leak Spots Retaining Walls

Waterproofing Systems We Handle

Every area has different characteristics, so the system used is tailored accordingly:

  • Polyurethane membrane — elastic, suited to factory roofs and open areas exposed to weather and structural movement.
  • Cementitious polymer coating — two-component waterproofing mortar for concrete structures like ground tanks and basements.
  • Integral waterproofing additive — mixed directly into mortar/plaster so the result is watertight from within.
  • Quick-repair sealant — for fixing leak spots on roofs, gutters, or areas hard to reach with a full membrane system.
