Waterproofing Systems / System 300

Waterbars, Waterstops & Waterplugs

A range of products used to waterproof construction joints and movement joints of retained concrete structures so that they become integrally waterproof – defined within BS8102:2009 as Type B waterproofing.

  • Newton 301 EasyProof (SX301)

    Metal Construction Joint Water Bar

    Newton 301 EasyProof is a coated metal water bar system used for the sealing of construction joints within retained concrete structures. It features an adhesive, reactive polymer coating on one of its sides. The coating creates a permanent watertight seal with the surrounding concrete to create a water bar that works immediately.

  • Newton 303 PolyProof

    High Grade Hydrophilic Waterbar

    Newton 303 PolyProof is a hydrophilic, thermoplastic elastomer water bar, which swells when activated by moisture. It is characterised by high elasticity and high tensile strength. 

  • Newton 306 SwellMastic

    Swelling Adhesive Mastic

    Newton 306 SwellMastic is a high quality, fast-curing, swellable, single-component, polymeric adhesive sealant. The special composition of Newton 306 SwellMastic makes the sealant swell when in contact with water (to about 200% of original size).

  • Newton 307 PipeSeal

    Pipe Collar To Provide Physical Water Bar

    Newton 307 PipeSeal is an advanced EPDM pipe collar that provides a physical waterbar for the waterproofing of pipes penetrating though earth-retained structures and to prevent water ingress around pipes and gullies to flat roofs and decks.

  • Newton 308 Stopaq

    Pipe Sealant For Pipes Through Service Duct Sleeves

    Newton 308 Stopaq is a single-component, highly flexible compound used for the sealing of conduits and pipes through service duct sleeves. The product is incredibly effective at sealing around numerous services within the sleeve, even where significant water ingress exists.

  • Newton 309-M Adhesive

    Elastic Adhesive Mastic

    Newton 309-M Adhesive is an MS polymer-based, durable and fast-curing elastic adhesive. It has a very high initial strength and bonds without primer on almost all materials used in the construction industry, including aluminium, galvanized and stainless steel, zinc, copper, natural stone, concrete, brick, cement-based cover sheeting, HPL panels,treated wood, gypsum, glass, glazing, and various synthetic materials.

  • Newton 313-WP WaterPlug

    Fast Setting Polymer Compound to Seal Leaks

    Newton 313-WP WaterPlug is a fast setting, polymer compound that instantly stops running water or seepage through masonry or concrete substrates.

  • Newton 314-BP Bentonite Powder

    Swelling Detailing Powder

    Newton 314-BP Bentonite Powder is a naturally occurring sodium bentonite powder used for detailing to the Newton HydroBondTM System, specifically where Newton 403 HydroBond terminates to otherwise difficult to detail building elements, such as piled walls, support piles, pile caps, and protrusions through the membrane.

  • Newton 315 Polymer-Waterbar

    High Grade Hydrophilic Waterbar

    Newton 315 Polymer-Waterbar is a hydrophilic, acrylate polymer waterbar, which swells when activated by moisture. It is characterised by high elasticity and high tensile strength. Newton 315 Polymer-Waterbar can be used to seal the structure against water leaks to both cast-in-place concrete and precast construction joints.
