From Drawings to Execution

At Gurtex® Waterproofing, we believe the strength of a project lies not only in its design but also in the precision and accountability of its technical execution. We collaborate closely with architects, design consultants, contractors, and developers to ensure that our waterproofing systems are implemented exactly as planned — right down to the smallest detail.

Responsible Technical Drawings

Before any project begins, our team carefully reviews all architectural and structural drawings. If drawings are incomplete or unavailable, we conduct detailed site inspections and generate custom technical drawings based on actual conditions. These become reliable reference points for all stakeholders during the execution phase.

Examples of Working Drawings & Implementation Details

Our role extends beyond simply following instructions — we actively enrich the process by producing detailed working drawings for every critical area of waterproofing application. All drawings are verified in collaboration with the lead architect to ensure full alignment with the original design vision.

Examples include:
• Roof-to-wall waterproof junctions
• Balcony leak prevention systems
• Drainage designs for basements and rooftops

Project Highlight: Outer Wall Waterproofing

Gurtex was entrusted with the design and application of a full-scale waterproofing system for the outer walls of a high-end structure. This project demanded precision due to:
Full exposure of vertical surfaces to Bali’s tropical climate, uneven and inconsistent existing concrete finishes, and limited accessibility, requiring the use of scaffolding.

Our Solution & Execution Strategy

Site Inspection & Mapping: Our technical team performed detailed on-site measurements and evaluations to assess exposure risks and drainage flow patterns.

Development of Custom Working Drawings: We produced dedicated shop drawings that included:
Defined application zones for SG368 (3-layer system), Geofabric reinforcement at all structural corners, and accurate surface area calculations and installation sequences.

On-Site Installation Process:
Surfaces cleaned using high-pressure washing equipment, irregular surfaces leveled with bonding slurry mix, Geofabric installed at internal corners and transition points, SG368 applied in three layers as per working drawings, and SG168 applied for UV resistance and final sealing.

Project Highlight: Bathroom Waterproofing

Bathrooms are continuously exposed to moisture and water. Without proper protection, water can seep through tile joints, floor-to-wall intersections, and drain edges—causing mold, odors, and eventual structural damage beneath the tiles.

Our Solution & Execution Strategy

Site Assessment & Moisture Mapping: We identified high-risk wet zones including shower corners, wall-to-floor junctions, pipe penetrations, and drain edges. These were mapped for reinforced waterproofing application.

Preparation of Technical Scope: Based on the layout, we outlined waterproofing boundaries for each substrate, material specifications, reinforcement zones, and planning for a 24-hour water retention test (if required).

Installation Procedure:
Surface cleaning and contaminant neutralization, application of primer for optimal adhesion, flexible waterproof membrane applied to floors and vertical surfaces, additional geofabric reinforcement at corners, joints, and around drains, and optional 24-hour ponding test before handover to tilers.

Design Alignment: Our system is designed to be fully compatible with ceramic tile installation, ensuring no lifting, bubbling, or delamination. Waterproofing layers remain completely hidden but fully functional beneath visible surface finishes.
