Weber Waterproofing - Engineered for 50+ years of protection
Weber waterproofing systems deliver documented longevity that sets the standard for UAE construction. The weberdry range combines polymer-modified cementitious membranes and polyurethane liquid systems to address every waterproofing challenge from bathroom wet areas to potable water tanks. With weberdry 110 FX offering a tested useful life expectancy exceeding 50 years, these systems represent long-term value rather than short-term savings. Lapiz Blue supplies the complete Weber waterproofing portfolio with technical guidance for substrate preparation, system selection, and proper application methods.

Why Weber Waterproofing from Lapiz Blue?
- 50+ year useful life expectancy - weberdry 110 FX documented performance for genuine long-term waterproofing
- Potable water tank certification - approved for drinking water reservoirs, cisterns, and water storage facilities
- Dual pressure resistance - handles both positive and negative hydrostatic pressure for versatile applications
- Low VOC formulations - weberdry products contain less than 10 g/l VOC for healthier indoor application
- Crack-bridging capability - elastomeric membranes accommodate substrate movement without failure
- Multiple application methods - brush, roller, or spray application for efficient coverage on any project size
Applications and Best-Fit Scenarios
Potable water tanks and reservoirs - weberdry 110 FX certification for safe drinking water storage
Basement tanking and below-grade walls - negative pressure resistance keeps groundwater out
Bathroom and wet room waterproofing - seamless membrane under tiles prevents moisture migration
Swimming pools and water features - continuous barrier for permanent water contact
Terraces and balconies - flexible membrane handles thermal movement and ponding water
Canal linings and tunnels - industrial-grade protection for infrastructure projects
How to Choose the Right Weber Waterproofing System
Identify water pressure direction - positive pressure (water pushing against membrane) vs negative pressure (water behind membrane) determines product selection
Check potable water requirements - only certified products like weberdry 110 FX should contact drinking water
Evaluate substrate condition - cementitious products bond to concrete; polyurethane handles varied substrates
Consider crack movement - static cracks need different treatment than active movement joints
Assess application access - spray systems cover large areas efficiently; brush/roller for detail work
Factor UV exposure - exposed applications need UV-stable topcoats or covering
Match system to tile finish - cementitious waterproofing under tiles, liquid membranes for exposed applications
Common Mistakes to Avoid
- Applying over damp substrates - most waterproofing requires dry surfaces; check moisture content before application
- Insufficient thickness - thin spots fail first; maintain specified wet film thickness throughout
- Skipping reinforcement at corners - internal corners and pipe penetrations need fabric reinforcement
- Rushing between coats - allow proper cure time between layers for full membrane development
- Using non-certified products for water tanks - potable water contact requires specific certifications

Frequently Asked Questions
Weber documents that weberdry 110 FX has a tested useful life expectancy exceeding 50 years under normal service conditions. This is based on accelerated aging tests and real-world performance data from installations across various climates and applications.
Yes. weberdry 110 FX is certified for contact with potable water, making it suitable for drinking water tanks, reservoirs, cisterns, and water supply infrastructure. Always verify certification requirements for your specific application.
weberdry 110 FX is a two-component polymer-modified cementitious coating ideal for concrete substrates, potable water, and below-grade applications. weberdry 350 PU is a single-component polyurethane membrane that bonds to varied substrates and is excellent for roofs and exposed applications.
weberdry 110 FX can resist both positive and negative hydrostatic pressure. This means it works for tanking applications where groundwater pushes against basement walls from outside, keeping moisture out of the structure.
Fabric reinforcement is required at internal corners, external corners, pipe penetrations, and crack locations. For general field areas on stable substrates, weberdry can be applied without fabric, but corners and details always need reinforcement.
Yes. weberdry 110 FX provides an excellent bonding surface for tile adhesives. Allow the membrane to cure fully (typically 24-48 hours depending on conditions) before applying tile adhesive. Use compatible Weber adhesives for best results.
Low VOC (less than 10 g/l in weberdry products) means safer application in enclosed spaces like basements, bathrooms, and occupied buildings. Applicators experience less exposure to fumes, and there is minimal odor during and after installation.
Substrates must be clean, sound, and free from oil, dust, and loose material. Concrete should be fully cured. Surface defects and honeycombing must be repaired. weber.rep repair mortars can address substrate damage before waterproofing application.
Documented Long-Term Performance
Unlike products that simply claim durability, Weber documents specific useful life expectancy based on testing and field performance. weberdry 110 FX carries a documented 50+ year useful life expectancy, providing genuine confidence in long-term waterproofing performance. This documentation supports lifecycle cost analysis for building owners and developers.
weberdry 110 FX Cementitious System
weberdry 110 FX is a two-component polymer-modified cementitious coating consisting of powder and liquid components. When mixed and applied, it cures to form an elastomeric, waterproof membrane that bonds permanently to concrete and masonry substrates. The system handles both positive and negative hydrostatic pressure, making it versatile for tanking, wet areas, and water storage.
Potable Water Certification
Many waterproofing products cannot safely contact drinking water due to leaching or contamination concerns. weberdry 110 FX carries specific certification for potable water contact, making it suitable for drinking water tanks, reservoirs, and water supply infrastructure where other products would be prohibited.
weberdry 350 PU Polyurethane System
For applications requiring adhesion to varied substrates or exposed membrane systems, weberdry 350 PU delivers single-component convenience. This polyurethane liquid membrane applies by brush, roller, or spray, curing to form a continuous waterproof barrier. It bonds to concrete, metal, bitumen membranes, and acrylic paints.
Low VOC for Indoor Safety
Weber waterproofing products contain less than 10 g/l VOC, significantly below many competing products. This low emission formulation enables safer application in basements, bathrooms, and other enclosed spaces. For projects in occupied buildings or with indoor air quality requirements, Weber products meet stringent environmental standards.
Crack-Bridging and Movement Accommodation
Building substrates move due to thermal expansion, settlement, and structural loading. Weber waterproofing membranes incorporate elastomeric properties that bridge existing cracks and accommodate future movement without failure. This flexibility is essential for long-term waterproofing performance in the UAE climate.
