    Product Offering


    Type A - Barrier protection against water ingress
    • MasterSeal 754 – Pre-applied FPO waterproofing membrane with MasterSeal 934 Waterproofing tape
    • MasterSeal 754 SB​ – Post-applied FPO waterproofing membrane for below ground concrete structures​​
    Type B - Structurally integral protection against water ingress

    Grades of Waterproofing

    BS 8102 classifies three grades of waterproofing protection – Grade 1 Basic Utility, Grade 2 Better Utility and Grade 3 Habitable.
    • Grade 1 environments include car parks, plant rooms (excluding electrical equipment) and workshops. BS 8102 defines the performance level of Grade 1 environments as ‘some seepage and damp areas tolerable, dependent on the intended use, local drainage might be necessary to deal with seepage’.
    • Grade 2 environments include plant rooms and workshops that require a drier environment than that of Grade 1. The performance level of Grade 2 is defined as: ‘no water penetration acceptable, damp areas tolerable; ventilation might be required’.
    • Grade 3 environments include ventilated residential and commercial areas, including offices, restaurants and leisure centres. The performance level Grade 3 is defined as: ‘no water penetration acceptable, dehumidification or air-conditioning necessary, appropriate to the intended use’.

    Types of Waterproofing Protection

    BS 8102 classifies three grades of waterproofing protection.
    • Type A barrier protection against water ingress which is dependent on a separate barrier system, typically bonded sheet membranes, applied to the structure.
    • Type B structurally integral protection against water ingress, which is provided by the structure. This type of waterproofing protection is actually integrated into the concrete structure and typical products used include water resisting admixtures compiling with Table 9 of BS EN 934-2:2009 (Admixtures for concrete, mortar and grout) for watertight concrete combined with appropriate joint sealing systems for connections, construction and movement joints
    • Type C drained protection against water ingress into usable spaces which is provided by the incorporation of an appropriate internal water management system.

    National House Building Council (NHBC) Risk-based Design

    Chapter 5.4 (Waterproofing of basements and other below ground structures) requires that waterproofing design should be appropriate to the risk and generally assume exposure to a full height of water during the design life of the building. Where ‘Grade 3 protection’ is required, and the below ground wall retains more than 600mm, measured from the lowest finished floor level, the waterproofing design should include a combination of two of the Types of waterproofing systems.
    Where Grade 2 waterproofing is required to walls retaining ground greater than 600mm, Type A systems that are not fully bonded should only be used as part of a combined system. combined systems include:
    • Type A and Type B
    • ​Type A and Type C
    • ​Type B and Type C
    Where there is any doubt about use, Grade 3 protection should be provided. Grade 3 structures built with a Type A and Type B waterproofing system would typically be:
    • Storage areas (moisture sensitive goods)
    • Electrical plant rooms
    • Ventilated residential units and offices
    • Restaurants and commercial areas
    • Leisure facilities
    • Residential areas
    • Computer rooms
    • Archive Rooms
    Grade 2 structures built with a Type A and Type B waterproofing system would typically be:
    • Underground car parks
    • Plant rooms
    • Workshops
    • ​Storage areas (moisture unaffected goods)

    Specifications

    Water is the most destructive weathering element for concrete, masonry, steel and stone structures, damaging or destroying more buildings and structures than war or natural disasters. Whether above-ground or below ground, all buildings must be able to resist unwanted water in some respect, in the form of rainwater, moisture or hydrostatic pressure. Hydraulic civil structures face yet more challenges in withstanding the ongoing effects of constant immersion.

    Good waterproofing, or water resistance, can be the key factor in ensuring a structure’s longevity, yet the importance of this facet of structural design is not always given the attention it warrants. The majority of problems with water ingress occur in a relatively small proportion of a structure’s surface area, often where design details meet. Careful consideration at the design stage can limit cracks, leaks and potentially serious structural damage over a structure’s lifecycle, providing that trades work together at the construction stage to implement design details successfully.

    With all this in mind we can offer a specification with a complete range of products to help make your structure BS 8102 compliant.
