Asphaltic plug bridge expansion joint
- UK highways approved
- Polymer modified bitumen binder blended with single sized aggregate
- Installed by our own crews
Our asphaltic plug bridge expansion joint is designed for movement capability up to +/- 25mm and provides a flexible and watertight seal for bridge decks whilst maintaining the ability to withstand heavy traffic loadings without rutting.
- Watertight seal prevents ingress of water and salts
- Quick to install during overnight lane closures to minimise disruption
- Smooth riding surface
- Topping replacement service available for replacing the top of existing joints when resurfacing
- Can be installed in part widths, minimising disruption to one lane at a time
Installation of crack inducers to focus future expected movement at the desired point and induce a controlled crack.
- Mark out on the site the exact location for the crack inducer.
- A saw cut is made to the required dimensions and the gap sealed with a hot poured bitumen based sealant.
- Future movement should be focused at the crack inducer, leaving the surrounding surfacing intact.
Using the adaptable Ironmaster system, we install bridge drainage channels to the high standards of a typical Ironmaster repair.
Using high strength, quick setting mortars our teams of experts are able to install a long lasting finish.
Our experience in finding solutions to difficult problems enabled us to contribute to a solution for removing surface water.
Pavix
Pavix provides concrete & masonry surfaces with permanent protection against moisture penetration and water associated damage, such as winter freeze-thaw cycles, chloride ion penetration and alkali / silica reactions.- Safe to apply & harmless to the environment
- Spray applied in one speedy application
- Unique dual action protection – hydroscopic & hydrophilic
- Seals the surface in the wet, breathes in the dry
- Imbedded crystals repel water and eliminate vegetative growth
- Approved for long term protection of structures
Pavix is a water based, water repelling, and crystal forming chemical. It is the only product that combines a water repelling agent with a crystalline formation in the pores and voids of the concrete, creating a double protection system.
- Reacts with the air to create a water repellent
- Penetrates into the concrete
- Forms crystals that are
- hydroscopic (grow by absorbing water and fill voids in pores)
- hydrophilic (migrate towards water source, effectively sealing it off)
- In the dry, crystals shrink in size to allow concrete to breathe
Pavix protects against:
- water & moisture intrusion
- moisture related problems caused by freeze / thaw cycle
- corrosion caused by chemicals, caustics, jet fuel & oil
- environmental damage caused by dirt & grime
- vegetative growth
A colourless, non-film forming liquid, Pavix is spray applied onto the surface, penetrating deeply into the pore structure in a simple, single application.
Non-toxic and non-hazardous:
- using water as a carrier to get the crystals into the structure
- can be used safely in the vicinity of rivers and water courses
- presents virtually no risk to the applicator
Independent endorsement:
- independently tested as a suitable alternative to Silane for protection of concrete structures
Dual action reaction:
- only product that both repels, and internally blocks water
Repels:
- does not discolour any surface to which it is applied
- repels dirt and grime
- eliminates fungus growth indefinitely
Resists:
- resists aggressive chemicals such as acids, caustics, jet fuel and oils
- reduces surface scaling
- seals cracks up to 1.4mm wide
Protects:
- protects reinforcing steel against the deteriorating effects of oxidation
- resists potentially damaging hydrostatic pressure
