RAFT SLAB WITH FOOTINGS -

l The RAFT SLAB WITH FOOTINGS that is to be treated should be minimum 7 days old.

PREREQUISITE FOR SUPERSHIELD WATERPROOFING TREATMENT

SUPERSHIELD SPECIFICATION AND APPLICATION METHODOLOGY

Provide, mix and brush apply two coat of SUPERSHIELD 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 concrete @ 1.5 Kg/m² for two coats on the RAFT SLAB WITH FOOTINGS.

1) Surface preparation - The concrete substrate that is to be applied with SUPERSHIELD 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 SUPERSHIELD 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 SUPERSHIELD CRYSTALGUARD as a slurry

consistency on the concrete surface.

5) Second coat of CRYSTALGUARD - Apply the second coat of SUPERSHIELD CRYSTALGUARD as a slurry

consistency on the first coat after a minimum of 4 hours gap.

Performance Criteria

Quality Assurance

l The SUPERSHIELD 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.

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 SUPERSHIELD specification

and application methodology.

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

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 1202-03

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 the use of waterproofing material on structures holding potable water shall be evidenced.

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.






Warranty

Submittals

A) Manufacturer's Warranty : Manufacturer shall provide standard product warranty executed by authorised

company official.

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.
