VEDAG

What VEDAG does

VEDAG is a waterproofing product manufacturer and system solution provider, with a brand heritage dating to 1846 in Leipzig, Germany, and China operations established in 1999 through Deweida (Shanghai) Building Technology Co., Ltd. The company's core technology centers on SBS modified bitumen waterproofing membranes, including surface and base layer membranes, root-resistant membranes (FLL-certified), vapor barriers (SD≥1500m, DIN EN 13970 compliant), and the proprietary dry-method construction system that eliminates wet mortar layers. Value-added product lines include the Noxite air-purifying membrane (CNRS-validated 81% NOx reduction under UV), VEDAPOINT steam channel membranes, and the PHI-certified passive house roof waterproofing insulation system (4LDU), making VEDAG China's first PHI-certified roof waterproofing company. The company operates a 100-acre manufacturing base in Yangzhou established in 2011 with a $7 million USD investment.

Revenue is generated through two streams: sale of waterproofing products (membranes, coatings, accessories, and home decoration products including tile adhesives, primers, putties, and art coatings) and integrated waterproofing system services (design, technical consultation, and professional construction). The go-to-market is project-driven direct enterprise sales targeting real estate developers, contractors, government entities, and infrastructure projects, with landmark references including the National Centre for the Performing Arts, Beijing Olympics underground facilities, Beijing Metro Line 7, Hangzhou Olympic Expo Centre, and Shanghai Expo's Hamburg House. Pricing is quote-based and project-specific, with no publicly disclosed tiers. The company is privately held, with no disclosed funding rounds or public listing, and operates a lean organizational structure with reported 1-10 employees (likely reflecting the Shanghai headquarters only). Distribution relies entirely on direct sales via the Shanghai office and Yangzhou production base, with no intermediaries or third-party distributors mentioned.

Scale indicators6 records

Recent moves8 records

Expansion highlights5 records

Broad incumbents

• Sika AG: Swiss global specialty chemicals and construction materials company offering waterproofing membranes, coatings, sealants, and roofing systems alongside adhesives and concrete admixtures. Sika competes with VEDAG in liquid waterproofing, roofing, and tunnel/infra waterproofing, and represents the diversified global benchmark for premium waterproofing.
• GAF Materials Corporation: North America's largest roofing manufacturer, offering modified bitumen membranes, TPO, and integrated commercial roofing systems. GAF is a scaled incumbent comparable on product breadth, system-solution positioning, and code/standards development participation.
• Bostik (Arkema): Global adhesives and sealants business of Arkema, with significant waterproofing, roofing, and construction sealant product lines. Bostik overlaps with VEDAG in modified bitumen adhesives, sealants, and construction chemical systems, representing a broader specialty chemicals incumbent rather than a pure-play waterproofing peer.
• Carlisle Construction Materials: US-based broad manufacturer of single-ply EPDM, TPO, and PVC membranes plus modified bitumen systems for commercial roofing. Carlisle is a scaled incumbent in waterproofing/roofing globally and a relevant comparable for VEDAG's commercial project-based sales motion and membrane product portfolio.

Direct peers

• Soprema Group: French-headquartered global manufacturer of SBS and APP modified bitumen waterproofing membranes, single-ply systems, and liquid-applied waterproofing. Soprema is the closest direct competitor to VEDAG in modified bitumen membranes, green roof systems, and integrated waterproofing solutions for commercial and passive/green buildings.
• Bauder GmbH & Co. KG: German manufacturer of SBS modified bitumen and single-ply waterproofing membranes with strong expertise in green roofs, passive house systems, and integrated roof build-ups. Bauder is the most direct European counterpart to VEDAG given shared German engineering heritage and similar premium green-roof and energy-efficient building positioning.
• IKO Industries: Canadian manufacturer of modified bitumen roofing membranes, self-adhesive membranes, and waterproofing systems. IKO is comparable to VEDAG in SBS modified bitumen technology, self-adhesive innovations, and project-based commercial roofing sales, with a strong export footprint including Asia.
• Oriental Yuhong (东方雨虹): China's largest waterproofing manufacturer, producing SBS/APP modified bitumen membranes, TPO/PVC membranes, coatings, and integrated systems. Yuhong is VEDAG's primary direct competitor in the Chinese waterproofing market, with broader product range and deeper domestic distribution but a less premium positioning.
• Keshun Waterproof Technology (科顺防水): Major Chinese waterproofing manufacturer offering SBS modified bitumen membranes, self-adhesive membranes, waterproof coatings, and integrated waterproofing systems. Competes with VEDAG across the same Chinese project-based customer segments.

Regional players

• Hongyuan Waterproof Technology (宏源防水): Established Chinese waterproofing manufacturer focused on SBS modified bitumen membranes and coatings for the domestic market. A regional direct competitor to VEDAG's standard SBS membrane offerings in China.
