All variations of the Admix C-Series contain the same amount of reactive chemicals at their prescribed dosage rates and provide the same waterproofing and durability performance characteristics.
Xypex Admix is blended into the concrete mix at the time of batching to waterproof and protect concrete from the start. It outperforms other methods because of its unique ability to become a truly integral part of the concrete matrix. The Admix C-Series has been specially formulated to meet varying project and temperature conditions.
Xypex Admix C-Series is available in regular or no-fines grades (NF):
Admix C-500/C-500 NF is formulated to have minimal or no effect on setting time. Admix C-1000/C-1000 NF is formulated for concrete mix designs where a normal or mildly delayed set is desired. Admix C-2000/C-2000 NF is designed for warmer climates and projects where a slower hydration rate is typically required.
See Setting Time and Strength for more details. Consult with a Xypex Technical Services Representative for the most appropriate Xypex Admix for your project.
For ease of use, Xypex Admix is available in pails, bags or soluble bags.
PART 1 - GENERAL
A. Section Includes: Furnishing of all labor, materials, services and equipment necessary for the supply and installation of cementitious crystalline waterproofing to concrete substrates, above-grade or below-grade, on either dry or wet side of substrates, as indicated on drawings and as specified herein.
B. Related Sections:
1. Section 031000 - Concrete Forming and Accessories
2. Section 079000 - Joint Protection
3. Section 099000 - Paints and Coatings
A. Applicable Standards: The following standards are referenced herein.
1. American Society for Testing and Materials (ASTM)
2. Army Corps of Engineers (CRD)
3. American National Standards Institute (ANSI)
4. NSF International
5. European Standards (EN)
7. Drinking Water Inspectorate (DWI)
1.03 System Description
A. Cementitious Crystalline Waterproofing: Concrete waterproofing and protection system shall be of the crystalline type that is a blend of Portland cement, fine treated silica sand and active proprietary chemicals. When mixed with water and applied as a cementitious coating, the active chemicals diffuse into the concrete and cause a catalytic reaction which generates a non-soluble crystalline structure within the pores and capillary tracts of concrete. This crystalline system causes the concrete to become sealed against the penetration of liquids from any direction, and protects the concrete from deterioration due to harsh environmental conditions. The system is used for above or below-grade walls and slabs, including liquid retaining structures and where enhanced chemical resistance is required.
1.04 System Performance Requirements
A. Testing Requirements: Crystalline waterproofing system shall have been tested in accordance with the following standards and conditions, and the testing results shall meet or exceed the performance requirements as specified herein.
B. Independent Laboratory: Testing shall have been performed by an accredited independent laboratory meeting the requirements of ASTM E 329 or other applicable international standard for certification of testing laboratories. Testing laboratory shall have obtained all control and treated concrete samples.
C. Crystalline Penetration: Crystallizing capability of waterproofing material shall be evidenced by independent SEM (Scanning Electron Microscope) photographs. Crystal growth 12 inches (30 cm) from the surface of the coating shall be evident with 1000X magnification 1 year after application of the coating and exposure of the sample to normal weathering.
D. Permeability: Independent testing shall be performed according to U.S. Army Corps of Engineers CRD C48 “Permeability of Concrete”. Concrete samples shall have design strength of 2000 psi (14 MPa) and thickness of 2 inches (50 mm). Treated samples shall have two coats of crystalline waterproofing applied per manufacturer’s directions. Samples to be pressure tested to 175 psi (405 foot head of water) or 1.2 MPa (123.4 m head of water). Control samples shall leak and treated samples, after crystalline growth has occurred, shall exhibit no measurable leakage.
E. Permeability - Negative Side Application: Independent testing shall be performed according to EN 12390–8 or other recognized direct pressure test. Concrete samples shall have a design strength of 25 MPa (3600 psi). Treated samples shall be exposed to water pressure on the side opposite to the crystalline coating. Coated samples shall exhibit a greater than 90% reduction in depth of water penetration as compared to the control samples.
F. Chemical Resistance: Independent testing shall be performed according to ASTM C 267 “Chemical Resistance of Mortars” and ASTM C 39 “Compressive Strength of Cylindrical Concrete Specimens”. Concrete samples (treated and untreated) shall have design strength of 4000 psi (27.6 MPa). Treated samples shall have two coats of crystalline waterproofing applied per manufacturer’s directions. Untreated and treated specimens must be immersed for a minimum of 84 days in following chemical solutions: hydrochloric acid (3.5 pH), brake fluid, transformer oil, ethylene glycol, toluene, caustic soda. Treated specimens shall exhibit no detrimental effects after exposure, and shall have an average of 17% increase in compressive strength versus untreated control specimens.
G. Acid Resistance: Independent testing shall be performed to determine “Sulfuric Acid Resistance of Concrete Specimens”. Treated concrete samples shall be tested against untreated control samples. All samples shall be immersed in 5% sulfuric acid and weighed weekly for 10 weeks. Untreated samples shall exhibit at least 8 times more mass loss than treated samples.
H. Carbonation Resistance Testing: Independent testing shall be performed according to RILEM CPC-18 or other recognized accelerated carbonation test. Concrete samples shall have a 0.5 w/cm ratio or be approximately 30 MPa (4500 psi) in strength. Coated samples shall have crystalline coating applied one day after casting and all samples to be cured for 7 days prior to carbonation. After 91 days exposure to CO2 the coated samples shall show a 35% or greater reduction in carbonation depth as compared to the control samples.
I. Potable Water Approval: Waterproof material shall have a current, valid approval certificate from NSF (NSF 61), DWI, or other recognized certification agency.
A. General: Submit listed submittals in accordance with conditions of the Contract and with Division 1 Submittal Procedures Section.
B. Product Data: Submit product data, including manufacturer’s specifications, installation instructions, and general recommendations for waterproofing applications.
C. Test Reports: Submit for acceptance, complete test reports from approved independent testing laboratories certifying that waterproofing system conforms to performance characteristics and testing requirements specified herein.
D. Manufacturer’s Certification: Provide document signed by manufacturer or manufacturer’s representative certifying that the materials to be installed comply with the requirements of this specification.
E. Manufacturer’s Field Report: Provide copy of report from manufacturer’s representative confirming that the surfaces to which waterproofing material is to be applied are in a condition suitable to receive same.
1.06 Quality Assurance
A. Manufacturer Qualifications: Manufacturer shall be ISO 9001 registered, and shall have no less than 10 years experience in manufacturing the cementitious crystalline waterproofing materials for the required work. Manufacturer must be capable of providing field service representation during construction phase. Manufacturers who cannot provide ongoing field support or the performance test data specified herein will not be considered for the project.
