RETAINING WALL INSIDE 101 2 TWO COATS OF CRYSTALGUARD @ 1.

(NEGATIVE SIDE) that is to be treated should be minimum 7 days old.

1 RETAINING WALL INSIDE TWO COATS OF 1.5 Kg/m RETAINING WALL OUT IN CRYSTALGUARD FIRST COATING CRYSTALGUARD SECOND COATING RETAINING WALL INSIDE (NEGATIVE SIDE) - PREREQUISITE FOR WATERPROOFING TREATMENT l The RETAINING WALL INSIDE (NEGATIVE SIDE) that is to be treated should be minimum 7 days old. SPECIFICATION AND APPLICATION METHODOLOGY Concrete Substrate Provide, mix and brush apply two coats of CRYSTALGUARD, single compound Deep Penetrating Capillary (DPC) waterproofing system that generates a non-soluble crystalline formation of dendritic fibers within the pores and capillary tracts of the 1.5 Kg/m² for two coats on the inside of the retaining wall (Negative Side). Application Methodology 1) Surface preparation - The concrete substrate that is to be applied with CRYSTALGUARD must be free from foreign materials and to be micro cleaned by mechanical means like wire brushing or vacuum cleaning. 2) Pre-wetting - Concrete surface must be thoroughly saturated with clean water prior to the coating to ensure moisture presence inside the pores and capillaries and remove any excess water and ensure surface is touch dry while coating. 3) Mixing of CRYSTALGUARD - Mix CRYSTALGUARD powder with clean water to form a slurry consistency with 5 parts of powder and 2 parts of water. 4) Application of CRYSTALGUARD - Apply the first coat of CRYSTALGUARD as a slurry consistency on the concrete surface.

2 RETAINING WALL INSIDE TWO COATS OF 1.5 Kg/m 5) Second coat of CRYSTALGUARD - Apply the second coat of CRYSTALGUARD as a slurry consistency on the first coat after a minimum of 4 hours gap. Curing l The CRYSTALGUARD coating should be cured with a misty fog spray of clean water, 24 hours after the application and to be kept moist for minimum 3 days. Watch Points Cracks, horizontal, vertical joint sealing, tie hole, pipe penetrations, construction joints, expansion joints and other defects in the concrete that is to be waterproofed should be treated as per the specification and application methodology. Performance Criteria Crystalline waterproofing system should meet or exceed the performance requirements as specified herein. l Crystalline Penetration : Crystallizing capability of waterproofing material shall be evidenced by l independent SEM (Scanning Electron Microscope) photographs documenting penetration of needle like crystal formation deep within concrete. l Self-healing capability and permeability resistance : Independent testing performed according to U.S. Army Corps of Engineers CRD-C48-73 "Permeability of Concrete". l Testing on the effectiveness of coating from negative side of concrete : Independent testing that demonstrates the capability of the coating to seal the leakage/dampness from negative side. l Resistance to chloride ion penetration : Independent testing performed according to ASTM C should exhibit a resistance of 100% better than that of the untreated specimen. l Potable Water Approval : Independent testing shall be performed according to EN or NSF Standard 61, and approval for use of waterproofing material on structures holding potable water shall be evidenced. Quality Assurance A) Manufacturer : Manufacturer should publish a third party product quality assurance certificate from a notified body with continuous surveillance audit or CE certificate with FPC (Factory Production Control) as per the harmonized standard EN to prove that the facility from where the material is produced for the project has undergone the required testing and extensive inspection and is under continuous surveillance by a notified body appointed by the European Union as per the European norms for the system. Manufacturers who cannot provide the performance test data specified herein and FPC certificate shall not be considered for the project. B) Applicator : Waterproofing applicator shall be experienced in the installation of cementitious crystalline waterproofing materials and shall be approved by the manufacturer in writing.

B) Applicator's Warranty : Applicator shall warrant the waterproofing installation against defects caused by faulty workmanship or materials for a period of (specify term) years from Date of Substantial Completion. The warranty will cover the surfaces treated and will bind the applicator to repair, at his expense, any and all leaks through the treated surfaces which are not due to structural weaknesses or other causes beyond applicator's control such as fire, earthquake and cyclone.

SPECIFICATION AND APPLICATION METHODOLOGY Concrete Substrate Provide, mix and brush apply one coat of CRYSTALGUARD, single compound Deep Penetrating Capillary (DPC) waterproofing 0.75 Kg/m² and one coat of CRYSTALGUARD ULTIMA, single compound highly concentrated crystalline coating as a top coat that generates a non-soluble crystalline formation of dendritic fibers within the pores and capillary tracts of the concrete with hard surface 0.75 Kg/m² on the inside of the retaining wall inside (Negative Side). Application Methodology 1) Surface preparation - The concrete substrate that is to be applied with CRYSTALGUARD /ULTIMA must be free from foreign materials and to be micro cleaned by mechanical means like wire brushing or vacuum cleaning. 2) Pre-wetting - Concrete surface must be thoroughly saturated with clean water prior to the coating to ensure moisture presence inside the pores and capillaries and remove any excess water to ensure surface is touch dry while coating. 3) Mixing of CRYSTALGUARD - Mix CRYSTALGUARD powder with clean water to form a slurry consistency with 5 parts of powder and 2 parts of water.
