Prior to waterproofing, all existing waterproofing material shall be removed and all concrete surfaces prepared according to the New Concrete Bridge Decks and Concrete Deck Overlays clause. Modification of Deck Joint Assemblies of Existing Bridge Decks. Wasser’s innovative Polyflex Bridge Deck System, has been specifically engineered to provide lasting protection to concrete and steel bridge decks. In its NCHRP Synthesis report, the National Cooperative Highway Research Program states that: “ concrete bridge deterioration is one of the most extensive bridge maintenance problems.
Salt and water can be a dangerous combination that can corrode concrete and weaken a bridge’s structure. Whether we’re rehabilitating an old bridge, or applying the first waterproofing on a new bridge, our skill and experience in bridge deck waterproofing will ensure the job gets done properly.

TRB’s National Cooperative Highway Research Program (NCHRP) Synthesis Waterproofing Membranes for Concrete Bridge Decks documents information on materials, specification requirements, design details, application Waterproofing membranes for concrete bridge decks book, system performance, and costs of waterproofing membranes used on new and existing bridge decks since SUMMARY WATERPROOFING MEMBRANES FOR CONCRETE BRIDGE DECKS Concrete bridge deck deterioration is one of the most extensive bridge maintenance prob- lems affecting the service life of bridges.
One cause of the deterioration is the penetration of moisture and chlorides into the concrete with subsequent corrosion of the steel rein- forcement.

To increase the durability of reinforced concrete bridges, all concrete movement and construction joints, plus the bridge decks have to be waterproofed to prevent serious damage to the concrete, or to the embedded.
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis Waterproofing Membranes for Concrete Bridge Decks documents information on materials, specification requirements, design details, application methods, system performance, and costs of waterproofing membranes used on new and existing bridge decks since This synthesis describes the state of the practice with respect to the development and present status of waterproofing membranes for concrete bridge decks.
This report of the Transportation Research Board describes the use of waterproofing systems applied to new bridge decks and the rehabilitation of deteriorated concrete bridge decks. The waterproofing of bridge decks is recognized in many European countries as a vital and necessary operation to enhance the durability and longevity of the life of bridge.
It represents the first line of defense and prevents the ingress of water, road de-icing salts, and aggressive chemicals which would corrode the steel reinforcing bars in. TRB’s National Cooperative Highway Research Program (NCHRP) Synthesis Waterproofing Membranes for Concrete Bridge Decks documents information on materials, specification requirements, design details, application methods, system performance, and costs of waterproofing membranes used on new and existing bridge decks since The synthesis focuses on North American practices.
THE USE OF WATERPROOFING MEMBRANES. ON CONCRETE BRIDGE DECKS. Background. The precast segmental bridge construction method was introduced to Hong Kong in the late eighties and has subsequently gained popularity.
Since water may seep through the joints between segments giving rise to corrosion of the steel elements.

concrete waterproofing system provides an excellent waterproofing membrane for bridges, parking decks or other vehicular traffic structures to be overlaid with an asphaltic concrete wearing course.
It is ideal for repair, maintenance or new construction applications. IntelliDeck is ideal for waterproofing elevated and rooftop decks. Our vinyl membranes (which is a code approved roofing material) are designed to be placed on new or existing decks shielding the area underneath against the weather and expanding your living space.
the concrete substrate and corroding the embedded steel reinforcement. The systems normally used consist of either sheet materials or a liquid coating bonded to the deck surface to form a waterproof membrane.
In the waterproofing of bridge decks became mandatory for. Dex-O-Tex waterproofing products offer protection for a wide range of residential and commercial surfaces from pedestrian walkways, to parking garages, to residential decks and balconies.
Our waterproofing products are specially designed to protect exterior concrete and decking surfaces against weather damage, UV radiation, and general wear and. WATERPROOFING OF CONCRETE BRIDGE DECKS [(Road Research)] on *FREE* shipping on qualifying offers.
Paris OECD. 4to., 89pp., printed wraps. Ex Author: (Road Research). Item Waterproofing Membranes for Structures 1. DESCRIPTION Furnish and place waterproofing membranes on concrete and steel bridge decks of railroad and other types of structures.

Parise. Bridge Decks No matter whether you’re working on a brand-new project or racing against time to finish refurbishment, there’s no room for compromise on waterproofing a bridge deck. Both the concrete itself and any embedded steel supports need to be protected with a versatile, flexible system which stands up to the rigours of everyday use.
Prior to waterproofing, all concrete surfaces shall be treated in accordance with the New Concrete Bridge Decks and Concrete Deck Overlays clause. Modification of Deck Joint Assemblies of Existing Bridge Decks Modifications to the expansion joint assemblies involving welding or File Size: KB.
ArmourBridge 45 Bridge, Deck and Waterproofing Membrane is composed of a tough non-woven reinforced polyester mat strengthened with select glass fiber strands. It is then coated with select SBS polymers and premium asphalt to a superior thickness of approximately mm ( mils).
This article describes an alternative method of waterproofing bridge decks using an acrylic or polyurethane spray rather than bituminous based sheet materials.
The spray systems consist of three basic elements (1) the primer which is applied direct to the substrate to provide a strong bond between the bridge deck and membrane; (2) the membrane Author: J Batchelor.Waterproofing materials like membranes are applied on top of bridge deck surface because: (i) Vehicular traffic (e.g.
tanker) may carry dangerous chemicals and the leakage of such chemicals in the absence of waterproofing materials may endanger the life of bridges. The chemicals easily penetrate and cause the deterioration of concrete bridge decks.Waterproofing. Water kills bridges.
Water seeps through the pavement eroding the structure and corroding interior metal supports. Waterproofing the bridge deck, can prevent water, chemicals, and debris from reaching the bridge structure.
