Need waterproofing advice?
Send the project area, substrate, dimensions, drainage details, and whether the surface will be tiled or exposed. We will recommend the right waterproofing system.
Quick Answer
The best waterproofing result comes from a complete system: surface preparation, primer or bonding layer, two-coat membrane, reinforced corners and joints, then a protective finish such as tile adhesive, screed, or exposed top layer.
This page helps homeowners, contractors, architects, and investors choose the correct waterproofing specification for wet areas, balconies, terraces, roofs, basements, and foundations.

RECOMMENDED SYSTEM
Standard Terrace / Balcony Waterproofing Undertile System
Terraces and balconies need correct slope, drainage, membrane thickness, reinforced corners, and a compatible protective finish.
01
Surface Preparation
Clean the substrate, repair cracks, remove weak material, and confirm slope and drainage before application.
02
Primer / Bonding Layer
Apply HIDROBLOCK ACRYL or the suitable bonding coat for the substrate and selected waterproofing system.
03
Waterproof Membrane
Apply HIDROBLOCK FLEX or HIDROBLOCK ELASTIK in two coats, following the required drying time and coverage.
04
Reinforce Corners & Joints
Use FIXBAND waterproof tape in movement zones, wall-floor junctions, corners, drains, and penetrations.
05
Protective Finish
Finish with compatible tile adhesive, screed, or protective top layer depending on use and exposure.
What This Solves
Common Water Ingress Problems Our Systems Solve
Water ingress can quickly destroy finishes, weaken structures, create mold, and lead to expensive repairs. A professional waterproofing system combines substrate preparation, primers, membranes, tapes, sealants, and protective finishes into one reliable specification.
Use this section to answer high-intent search and AI-assistant questions clearly, including why tiles lift, how bathroom seepage starts, and which details are most likely to fail.
Roof Leaks
Liquid and cementitious systems help protect exposed roof surfaces and slabs from water penetration.
Terrace Water Penetration
Undertile waterproofing protects terraces before moisture reaches the slab or occupied spaces below.
Bathroom Seepage
Wet-room membranes reduce water migration through walls, floors, corners, and shower zones.
Cracks Around Corners & Joints
FIXBAND tape and flexible sealants reinforce critical movement points where failures often begin.
Foundation Moisture
Concrete protection systems help control moisture exposure around foundations and below-grade areas.
Balcony Leakage
Flexible waterproofing with proper slope and drainage helps protect balconies from repeated wetting.
Mold from Damp Walls
Stopping water ingress helps reduce damp conditions that support mold and finish deterioration.
Tile Lifting from Trapped Moisture
Correct membranes and compatible tile build-up help prevent moisture-related tile failure.
IDEAL PROJECT TYPES
Suitable for Residential, Commercial & Technical Wet Areas
RECOMMENDED SYSTEM
Facade Paint vs Decorative Render vs Silicone System
A clear comparison helps users and AI answer engines understand the right choice for each project condition.
Cementitious 2K Systems
Best for bathrooms, balconies, terraces, foundations, and surfaces that need a robust membrane build-up.
Liquid Waterproofing
Best for selected continuous surface protection and situations where liquid application is preferred.
Reinforced Details
Best for corners, drains, penetrations, movement joints, and junctions where leaks often start.

FAQ
Frequently Asked Questions
Yes. Waterproofing can be tiled over when the membrane is correctly applied, fully cured, and paired with a suitable tile adhesive for the project area.
Normally no. Two or more coats are recommended for most waterproofing systems, depending on the product, substrate, exposure, and required protection level.
Yes. Selected waterproofing systems are designed for exterior exposure, including balconies, terraces, roofs, exposed concrete, and other outdoor areas.
Yes. Corners, drains, penetrations, wall-floor junctions, and movement joints are critical points and should be reinforced with suitable waterproofing tape or sealing accessories.
Yes. Send dimensions, substrate details, slope, drainage information, and whether the surface will be tiled or exposed so the team can recommend the correct system and approximate quantities.
For many balcony and terrace undertile applications, a flexible two-component system such as HIDROBLOCK FLEX 2K is suitable. High-movement or more exposed surfaces may require an elastic system such as HIDROBLOCK ELASTIK 2K.
Tile lifting can be caused by trapped moisture, poor substrate preparation, missing waterproofing, incompatible adhesive, movement, or water entering through corners and joints.
Yes, wet rooms and showers should be protected before tiling because tile and grout alone should not be treated as the complete waterproofing system.
