JinXing Waterproofing & the Dong'an Watchtower

The Dong'an Watchtower,as the only ancient-style structure among the Olympic venues,is the first stage of the 12th scenic area of Beijing, serving as the core auxiliary building of the Beijing Olympics. It hosts major functions such as athlete accommodations and VIP viewing, plays a vital role in international diplomatic events, and showcases China's cultural depth to the world.

And this landmark of Beijing city’s new skyline,

the Olympic 'Star' building’s waterproofing project,

was completed in 2020 by JinXing Waterproofing Group!

Waterproofing Design

The Dong'an Watchtower waterproofing project strictly follows ecological priority and green development principles, aiming to maximize scenic resource utilization. By leveraging and improving natural mountain and water landscapes, it provides an exquisite viewing experience for people worldwide and supports Beijing’s vision of creating a 'park within the city'.

Main Waterproof Materials

Dong'an Watchtower ProjectBasement floor uses 1.5mm JX HDPE High-Density Polyethylene Self-Adhesive Waterproof Membrane (double-sided adhesive) + 1.5mm JX Reactive Type High-Strength Cross-Linked Membrane (single-sided adhesive)..

JX HDPE High-Density Polyethylene Self-Adhesive Waterproof Membrane is an eco-friendly, environmentally sustainable waterproof membrane developed and produced by our company. This membrane can seamlessly bond with clean or mixed mortar and soil base layers, forming a self-adhesive polymer modified asphalt waterproof membrane with excellent adhesion properties.

JX Reactive Type High-Strength Cross-Linked Membrane is a high-performance, cold-applied, self-adhesive composite membrane made from specially processed high-density polyethylene (HDPE) reinforced membranes combined with premium high-polymer self-adhesive felt. It features outstanding dimensional stability, thermal stability, UV resistance, and bidirectional tensile strength.

Auxiliary Materials

Waterproof coatings, sealants, joint tapes, gaskets, etc.

Construction Techniques

Construction Methods

This project adoptsHDPE Method, effectively achieving full-seam bonding between the waterproof membrane and the structural body.

Construction Process

Base preparation → Primer application → Additional layer and detail treatment → Layout alignment → Large-area HDPE membrane laying → Seam lapping → Self-inspection & quality protection → Final inspection & acceptance.

Project Features, Challenges & Innovations

Dong'an Lake Park Aerial View

The Dong'an Watchtower project demonstrates deep insight, unique design concepts, and abundant professional expertise in ancient architecture design, imitation ancient design, historical relic planning, and tourism planning.To ensure construction quality, JinXing Waterproofing has fully promoted standardized construction practices across all Olympic auxiliary buildings, including:Standardized on-site management, standardized work processes, standardized construction techniques, and modernized equipment use.. At the same time, using industry-leading materials, through one-time construction and two-layer waterproofing, we achieve broad market recognition. Not only do we strictly enforce standardization in construction and management, avoiding leakage risks caused by human factors, but we also guarantee project quality, successfully realizing both aesthetic appeal and practical durability!
