The interactive workshop on the latest trends and appropriate

use of waterproofing and construction chemicals

Basement waterproofing Joint waterproofing Roof waterproofing

Basically they have given emphasize on following 3 areas

A- The Ground Conditions of basements:-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. A part or partial waterproofing treatment can also be achieved with drainage or porous screeds that are laid to falls on horizontal surfaces to drain off any water.

Material Specification Or details

Rigid Waterproofing (Grades 1 to 3)  Flexible Waterproofing (Grades 2 to 4) 

Waterproof concrete/waterproof rendering and joint sealing systems

Loose laid and welded sheet membranes 

To seal structures against groundwater ingress, where some limited moisture presence or damp patches are tolerable. Note: Can be used for Grades 3 and 4 with additional Sika jointing, waterproofing and other technologies.

To waterproof all types of structures in all different ground conditions against all types of groundwater ingress including high water levels with strong hydrostatic pressure even where the internal environment must be totally dry (i.e. Grade 4 in areas with a totally controlled environment or other special requirements).

Apply procedure

This membrane can be simply putted on PCC and seam overlaps of the membranes should securely and homogeneously welded with electric heat welding machines; this can be done manually with hand welding guns, or automatically with self-propelled machines.

A compartmental waterstopping system with Sika® Waterbars and welded double layer Sikaplan® sheet membranes is combined with Sika® injectable pipes and ports cast into the concrete structure, to provide the security of complete watertightness control, allowing fast location, then fast and easy repairs using Sika® injection resins, if this is ever required at any time during the construction period or during the entire service life of the structure.

EFFECTS

Leaks through damaged membrane are easily detected as water appears in the Sika® Control pipes and injection portsPossible Reasons for Membrane Waterproofing System Leaks- Membrane perforated during

construction works Welded seam overlaps not

professionally welded and tested to be watertight

Torn membrane after excessive settlement or other structural movement

 Repairing the waterproofing by the injection of Sika® Injection-305 resin through the Sika®

Control pipe and injection port.

 Sika® Injection-305 A flexible, very low-viscous and fast-reacting polyacrylate injection gel for the permanent watertight seal ing of damaged membrane waterproofing installations (both single and double layer systems). The material reacts to form a waterproof, flexible but solid gel with good adhesion to both dry and wet substrates.

 Two-Component Sika® Injection Pump for Polyacrylate Gels The Sika® Injection Pump PN-2C is specially designed for full curtain injection watertight sealing. A two-component pump is required, for the fast-reacting polyacrylate gels to the individual components are introduced sepa rately and mixed at the gun. The actual mixing takes place in a static mixer in the head. Suitable injection packers are inserted into the Sika® Control system injection ports.

Injection Pump

As per our site condition most of seepage or leakage occurs where we cross services line through structures. For packing this we do micro concreting, water proofing chemicals mixing in concrete or some other means but after taking care of all these things we finds seepage or leakage at some points.so for protection of this sika has suggested a material called sika swell s-2 a water swellable sealant

Sika Swell S-2 is one component polyurethane sealant which swells in contact with water.

JOINT WATERPROOFINGMATERIAL-SikaSwell® S-2 Sealant(Water swellable Sealant for

Construction Joints and Penetrations)

UsesSikaSwell S-2 is suitable for sealing watertight concrete construction

joints, penetrations

Sealing of Day work Joints No mechanical fixing required No jointing required No mechanical protection

required Suitable for vertical and

horizontal joints Not suitable for expansion joints

Connecting new to existing Construction No influence on finished external

appearance Simple preparation of existing

concrete surface; clean from dust, oil, cement laitance

Sealing of PVC Water bar Overlaps For sealing PVC water bar overlaps

Sealing of Cracks Excellent sealing properties Non-visible on external surfaces Little preparation/breakout Quick solution Works in mat moist conditions

Between different Construction Materials Excellent adhesion on many

common materials Easy to use

What is MTC System- SikaRoof® MTC (Moisture Triggered Chemistry) Systems incorporate a unique technology that allows the material to use atmospheric moisture to trigger the curing process. This means the waterproof membranes are capable of curing in a wide range of conditions including extreme temperature ranges and humidity variations. Unlike traditional polyurethane systems they do not release CO2, which often causes gassing, and application is not delayed by adverse weather conditions. It is not recommended to install the SikaRoof® MTC systems .when rain is imminent, as rainfall could affect the appearance of the product. However, once applied the membranes are waterproof and will not show an adverse
