Flexible Waterproofing with Sika Membrane Technologies
SIKA SOLUTIONS THE SINGLE LARGEST CAUSE OF DAMAGE to the building envelope is commonly accepted to be attributed to water ingress.a clear understanding of the building environment including its application requirements, as well as current and future surrounds, is crucial to establishing a strong set of waterproofing requirements. Requirements analysis is the crucial first stage in the development of a robust waterproofing specification that will allow a construction that provides optimal longevity, as well as low operation and maintenance costs. A holistic life cycle approach is recommended to achieve this goal. This same approach is also recommended when remedial works are required. Sika Flexible Membrane Technologies, in concert with White Box Technologies, (see Watertight Concrete Brochure) allow for the design and construction of totally watertight structures. Sika waterproofing technologies are available to meet all requirements for waterproofing of a structure.

SUB-GRADE SYSTEMS When selecting a sub-grade waterproofing system the following should be considered; Ground water pressure Ground water or soil contaminants Geological stability Construction methodology Allowable water ingress or dampness Life expectancy requirement THE GROUND CONDITIONS Basements are immersed in differing levels of groundwater, and aggressive influences including damp soil contact, percolating water, water under hydrostatic pressure plus aggressive chemicals in solution, different soil, gravel and rock, etc. These all require different and often specific waterproofing treatments to be applied to the structure. SIKALASTIC -1K Flexible cementitious based membrane Potable water certified Provides anti-carbonation protection to concrete Simple to use. Just add to water Suitable for use on various substrates can be applied to damp substrates Recommended for protection of structures subject to flexural loads SIKALASTIC POLYUREA Plural component, liquid applied membrane Very fast cure Rapid application Suitable for use on various substrates Good elongation and tensile strengths Low VOC, 100% solids UV stable SIKAPROOF A-12 Biological Attack Dynamic Force Condensation Percolating Water Frost Flexible Polyolefin (FPO) Based fully bonded membrane Rapid and simple application [no welding required] Third party tested watertight integrity for all detailing / termina tions (to 5 bar [50m] head of water pressure) Very good elongation characteristics [>450%] and tensile strength Grid Seal Technology to eliminate lateral flow of water in the event of damage to 7 bar (70m) Rising capillary Water Statical Pressure Uplifting Force Gas (Methane, radon) SIKAPLAN Chemically aggressive groundwater Chemically aggressive groundwater Polymeric based membrane, available in PVC or TPO, are well proven in construction globally. Offers design life performance of more than 100 years Used in the most demanding of waterproofing applications Quality assurance systems to provide surety in watertight integrity Can offer Totally Dry waterproofing when combined with Sika waterbar, and Sika Control systems Offers the most cost effective long term waterproofing solution All sub-grade systems can be optionally interfaced with SikaDur Combiflex SG, Sika waterbars, SikaSwell and SikaFuko injection hoses to provide the highest levels of watertight integrity, as well as provide redundancy to the primary waterproofing system.
