Interior Waterproofing
Mechanical Rooms
Waterproofing for plant rooms, wet utility areas and floors that must contain incidental water and resist wear.
ConcreteCementitious surfaces
Why this application fails
Where problems start
- Floors are penetrated by many services
- Incidental water and washdown find unsealed junctions
- Equipment plinths and drains are under-detailed
- Traffic and equipment wear the surface
Conditions to evaluate
- Substrate and moisture
- Penetrations and service routes
- Drainage and containment needs
- Traffic and equipment loads
