John Newton & Co have been protecting buildings from the effects of water ingress for more than 160 years and have now included into their portfolio a range of concrete waterproofing solutions using the latest technologies offering the specifier the ability to protect the entire envelope of the structure from below ground base slab, earth retained walls to concrete deck waterproofing solutions, all from a single source.
The innovative and proven new Newton System 300 Waterproofing of Concrete Structures range which has been installed throughout Europe and worldwide, includes:
■Newton 301 Aquaproof coated metal water bar which gives instant protection to construction joints against water ingress
■Newton 302 Injection Hose maintainable injection water bar system
■Newton 303/4 Polyproof hydrophilic and re-injectable waterbars
■Newton 308 Stopaq a unique swelling sealant for pipe penetrations
■Newton 403 Hydrobond externally applied bonded membrane
■Flexproof X1 - external construction joint compound
Benefits Of A Combined Waterproofing Approach
BS8102:2009: The Implications
When tasked to waterproof retaining structures in accordance with BS8102:2009 Code of Practice for Protection of Below Ground Structures Against Water from the Ground, professional waterproofing designers should now consider using more than one type of waterproofing to provide enhanced protection of the structure to achieve the necessary environmental grade.
Newton provide waterproofing products for all three types of waterproofing as defined within BS8102:2009:
■Type A (barrier) protection Newton System 100 Cementitious Products, Newton System 200 Deck and Roofing and Newton System 400 External Waterproofing
■Type B (structurally integral) protection Newton System 300 Waterproofing of Concrete Structures
■Type C (drained) protection Newton System 500 Cavity Drain Waterproofing
Combination strategies provide increased waterproofing protection to the structure. The provision of a maintainable waterproofing system is recommended within BS8102:2009 and Newton can provide maintainable options for all three types of waterproofing defined by the British Standard.
Installation of Newton 302 InjectionHose or Newton 304 PolyProof-Inject allows for re-grouting and resin sealing of defects that may appear post construction and Newton System 500, incorporating Newton Basedrain, provides a maintainable waterproofing system that can be accessed without detriment to internal finishes.
