Concrete Bridge-Deck Waterproofing underneath hot-rolled Asphalt High performance bridge-deck waterproofing solution under hot-rolled asphalt based on our liquid applied polyurethane and polyurea Sikalastic 800 range.
M-400A is a 70 mil, internally reinforced sheet waterproofing membrane for use on bridge deck structures. Membranes are provided in rolls inter-wound with a release film to prevent self-adhesion to the material in the roll. There is no paper backing to remove. Installation errors can be corrected during application.
Spray applied, seamless bridge deck waterproofing PmB is a two part, spray applied, durable corrosion protection and waterproof material. The high performance system is 100% polyurethane containing no fillers or additives and is VOC free.
Bridge Deck Waterproofing Systems Two types of Bridge deck waterproofing systems are available for use: Sheet Systems These are Polymer Modified Bituminous sheets bonded to the bridge deck, using torch application, hot mopping asphalt, or through self-adhesion.
The world’s first cold, spray applied bridge deck waterproofing system, the ELIMINATOR? membrane revolutionised the waterproofing industry. Airless spray equipment has been specifically developed to meter, mix and apply the product to offer fast, simple and effective sealing, even on complex detailing.
Over 40 years ago, we pioneered the use of cold, fluid applied waterproofing, revolutionizing the industry as Stirling Lloyd. Since then, our bridge deck waterproofing solutions have been continuously developed to meet the most challenging of road and rail bridge projects.
Bridge Deck Membrane? is a rapid setting, 100% solids, two-component polymer product. Bridge Deck Membrane? is used as a waterproof membrane with dielectric properties for protection against typical corrosion conditions that exist on many rail and DOT structures.
4. Asphalt bridge decks are not common. If you encounter one, please call W. R. MEADOWS technical services at (800) 342-5976 for assistance. 5. Steel bridge decks require waterproofing. If the deck is new, the steel surface will require a scratch/ leveling course of asphalt applied to it.
The Ultraseal Waterproofing System is a built up multi-layer system used to protect the pavement surface from chlorides, water penetration and other harmful materials. The system is made up of four parts – Ultraseal Primer, Ultraseal Reinforcing Fabric, Ultraseal Bridge Deck Membrane, and Ultraseal Protection Board.
USL BridgeCare provides Bridge Deck Waterproofing services to combat structural corrosion caused by wear, weathering & water-ingress arising from contact with de-icing. A high performance 100% effective seamless bridge deck waterproofing membrane that is extremely durable & flexible.
The world’s first cold, spray applied bridge deck waterproofing system, the ELIMINATOR? product revolutionized the waterproofing industry. Airless spray equipment has been specifically developed to dispense, mix and apply the product to offer fast, simple and effective sealing, even on complex detailing.
The Bridge Deck Waterproofing Systems, generally consists of 3 main layers viz. the concrete slab/ main deck, the layer of mastic and the final concrete/bitumen road. The mastic is required to bond the final road with the bridge deck.
The waterproofing of bridge decks is widely recognised as a vital and necessary operation to provide a defense barrier against these contaminants which include, water, road de-icing salts and aggressive chemicals which would corrode the steel of the reinforcing bar within the concrete, which would severely damage the structures integrity.
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. 914.07.02.04 Modification of Deck Joint Assemblies of Existing Bridge Decks
TRB’s National Cooperative Highway Research Program (NCHRP) Synthesis 425: 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 1995.
Bridge Deck Application ? Prepare deck ? Primer or Tack Coat (Bonding Adhesive) ? Apply primer to deck by roller, spray, brush, or squeegee ? Application rate of 200-400 Y2 per gallon ? Completely wetted with no puddling ? Place Membrane Bridge Deck Application ? Position & roll out ? Keep material taunt ? Start at curb or gutter
