The Components of Sika ® -1 WaterThe Sika ® -1 Waterproofing System can be designed to“keep water in” or to “keep water out”.With rising groundwater in many areas, coupled with the ever increasingcommercial need to optimise land usage by creating and re-creating habitablebasement areas, there is a need for effective and durable waterproofing in bothnew and refurbishment works.Similarly, with ever stricter controls on water quality, many existing structures,for the retention of potable water or for the protection of ground water fromeffluents, will need upgrading.Applied internally or externally, the cementitious Sika ® -1 WaterproofingSystem has provided the answers for over 90 years. Using neither sumps orpumps the Sika ® -1 Waterproofing System forms an integral part of thestructure to which it is applied, and is designed to last the lifetime of that structure.▲ Keeping Water Out▲ Basements▲ Underground Car Parks▲ Metro Stations and Subways▲ Utility Vaults▲ Marine Structures▲ TunnelsSika ® -1 Mortar TechnologyDense impervious mortar is produced by minimisingcapillaries and using pore blocking techniques.▲ Keeping Water In▲ Reservoirs▲ Water Tanks▲ Waste Water Treatment Plants▲ Secondary Containment Bunds▲ Swimming Pools▲ Sewers and Pipelines2▲ Keeping Water In ▲ Keeping Water Out ▲ Keeping Water In

proofing SystemThe Sika ® -1 Waterproofing Systemconsists of a specialist liquid admixture andpre-bagged quality controlled mortars.Sika ® -1 mortars consist of kiln driedpre-batched precision graded aggregates andcements, in 3 easily identifiable grades withsimple colour striping to ensure site qualitycontrol.Sika ® -1 admixture is a colloidal silicate liquid,diluted and incorporated into the mortar mixproducing a complete waterproofing system.Durability“Under normal conditions of use, theSika ® -1 Structural WaterproofingSystem will provide an effective barrier to thetransmission of liquid water for the life of thebuilding to which it is applied”.As quoted in British Board of Agrément Certificate.

Sika ® -1 Waterproofing SystemNote: Full installation guide and detailing sheets for Sika ® -1 Waterproofing System are available on request1. All materials must be stored inclean dry conditions2. Suitably qualified and experiencedcontractors should be used.3. All surfaces must be thoroughlymechanically prepared.7. Immediately prior to installation ofSika ® -1 Waterproofing System,saturate the surface with clean water.8. The first wall coat of Sika ® -1Spritz Mortar is "cast" vigorouslyonto the wall at 6mm thickness.9. The 2nd and 3rd wall coats ofSika ® -1 Render and FinishingMortar are trowel applied to aminimum 6mm per coat.13. A Sika ® -1 Bonding CoatMortar is brush applied as a slurryto the prepared floors.14. The 2nd and 3rd coats of Sika ® -1Screed Mortar are applied to thefloor by trowel and lapped onto wallfinishes.15. All service entries must be filled withSika ® -1 Waterproofing Systemand sealed using high performancesealants Sikaflex ® -11FC+,SikaSwell ® or SikaDur ® -Combiflex ® System.4▲ Keeping Water In ▲ Keeping Water Out ▲ Keeping Water In

Application Guide4. All joints should be protected bySikaDur ® -Combiflex ® Systemincorporated within the render.5. Sika ® -1 Waterproofing admixtureshould be diluted 1:10 with freshclean water to make up a gaugingsolution.6. Sika ® -1 pre batched Mortars mustbe mixed in forced action mixers usingSika ® -1 gauging solution.10.Keying between trowelled mortars isachieved by application of splattercoats of Sika ® -1 Spritz Mortar.11.Dry joints in wall finishes should belapped by a minimum of 100mm.Similarly wall finishes should belapped onto floors.12. If no SikaDur ® -Combiflex ®System joint is used at floor/wallinterface, a Sika ® -1 RenderMortar corner fillet must be included.16. Fixings must be secured usingSikaDur ® -31, Sika Powerfix ®resin adhesives, or Sikaflex ® -11FC+ polyurethane adhesivesealants.Do Not Drill into system17. Final plaster finishes suitable fordecoration can be produced withSikaMur ® Finish.18. For additional demands such asmechanical and chemical resistance,or crack bridging etc; use compatibleSikaGard ® or Sikafloor ® coatings.Keeping Water Out ▲ Keeping Water In ▲ Keeping Water Out5

Sika ® Vapour Barrier Systems▲ Impermeable Moisture Barriers▲ Solvent Free▲ Fast Track Construction▲ Unique Sika ® Epocem ® TechnologyWhere total vapour impermeability is demanded in addition to structural waterproofingas part of a Grade 4 system under BS 8102, this can be achieved by using a Sika ®Vapour Barrier System.Sika ® Vapour Barrier Systems comprise SikaGard ® -720 EpoCem ® for wallsand Sikafloor ® -81 EpoCem ® for floors sealed with solvent free SikaGard ® andSikafloor ® epoxy resin coatings.SikaGard ® and Sikafloor ® EpoCem ® provide a temporary moisture and vapourbarrier allowing the application of the appropriate SikaGard ® / Sikafloor ® solventfree epoxy resin coating to produce a permanent and moisture vapour resistant finish.Similarly, this system can be used on new concrete structures where residual moisturelevels are too high for the installation of finishes.Alternatively, SikaDur ® Liquid Damp-Proof Membrane can be installedwhere there is no current anticipated water pressure to help achieve a Grade 4installation under BS 8102 – please contact Sika for full technical advice.Excess moisturevapour absorbedby free cement inSikafloor ® ®-81 EpoCemSikaGard ® /SikaDur ®Sikafloor ® coatingKeeping Water Out ▲ Keeping Water In ▲ Keeping Water Out 7
