Concrete Waterproofing and Durability Enhancement Using Supershield DPC Crystalline Technology

www.supershieldglobal.com

ROOF SLAB - PREREQUISITE FOR SUPERSHIELD WATERPROOFING TREATMENT

l The ROOF SLAB that is to be treated should be minimum 7 days old.

l The pipe penetrations through the horizontal brick walls should be packed and plastered to a

minimum thickness of 25 mm with the ratio of 1:3 cement mortar.

l The side walls that are of non-concrete should be plastered to a minimum thickness of 25 mm with the ratio

of 1:3 cement mortar to a height of minimum 6" above the gradient level.

SUPERSHIELD SPECIFICATION AND APPLICATION METHODOLOGY

Provide, mix and brush apply two coats 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 roof slab and the adjacent curb wall

that are of concrete to the height of 6" above the filling level.

Provide, mix and brush apply two coats of SUPERSHIELD FLEXI, two component material that forms seamless

flexible membrane @ 1 .2 Kg/m² on the side walls to height of 6" above the filling level. The coating should

overlap a minimum 1” over the crystalline coating at the junction.

Performance Criteria

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.

Continue with the SUPERSHIELD FLEXI membrane coating on the non-concrete substrate after 8 hours of

crystalline coating.

6) Mixing of FLEXI - Mix SUPERSHIELD FLEXI A component (Powder) with SUPERSHIELD FLEXI B

Component (Liquid) as per the pre-measured packaging.

7) Application of FLEXI - Apply the first coat of SUPERSHIELD FLEXI as a slurry consistency on the non-concrete

plastered side walls, overlapping the crystalline coating for 2" at the junction.

8) Second coat FLEXI – Apply the second coat of SUPERSHIELD FLEXI as a slurry consistency on the first coat

after a minimum of 4 hours gap.

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.

l The SUPERSHIELD FLEXI should be air cured for minimum 3 days and protected from water/ rain for

minimum 18 hours.

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 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.

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.
