07160 <\/strong>| CEMENTITIOUS CRYSTALLINE<\/strong><\/p>\n Concrete Waterproofing[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_column_text]Xypex is a unique chemical treatment for the waterproof-ing, protection and repair of concrete. XYPEX CONCEN-TRATE is the most chemically active product within the Xypex Crystalline Waterproofing System. When mixed with water, this light grey powder is applied as a cemen-titious slurry coat to above-grade or below-grade con-crete, either as a single coat or as the first of a two-coat application. It is also mixed in Dry-Pac form for sealing strips at construction joints, or for the repairing of cracks, faulty construction joints and honeycombs. Xypex pre-vents the penetration of water and other liquids from any direction by causing a catalytic reaction that produces a non-soluble crystalline formation within the pores and capillary tracts of concrete and cement-based materials.[\/vc_column_text][vc_row_inner][vc_column_inner width=”1\/2″][vc_column_text]Recommended for:<\/p>\n \u2022 Reservoirs Advantages<\/p>\n \u2022 Resists extreme hydrostatic pressure Packaging<\/p>\n \u2022 Xypex Concentrate is packaged in various sizes.

As a cementitious powder or mixture, Xypex may cause significant skin and eye irritation. Direc-tions for treating these problems are clearly detailed on all Xypex pails and packaging. The Manufacturer also maintains comprehensive and up-to-date Material Safety Data Sheets on all its products. Each sheet contains health and safety information for the protection of work-ers and customers. The Manufacturer recommends you contact Xypex Chemical Corporation or your local Xypex representative to obtain copies of Material Safety Data Sheets prior to product storage or use.<\/p>\n Warranty<\/strong><\/p>\n The Manufacturer warrants that the products manufac-tured by it shall be free from material defects and will be consistent with its normal high quality. Should any of the products be proven defective, the liability to the Manu-facturer shall be limited to replacement of the product ex factory. The Manufacturer makes no warranty as to merchantability or fitness for a particular purpose and this warranty is in lieu of all other warranties expressed or implied. The user shall determine the suitability of the product for his intended use and assume all risks and liability in connection therewith[\/vc_column_text][vc_column_text]Application Procedures<\/p>\n 1. SURFACE PREPARATION Concrete surfaces to be treated must be clean and free of laitance, dirt, film, paint, coating or other foreign matter. Surfaces must also have an open capillary system to provide \u201ctooth and suction\u201d for the Xypex treatment. If surface is too smooth (e.g. where steel forms are used) or covered with excess form oil or other foreign matter, the concrete should be lightly sand-blasted, waterblasted, or etched with muriatic (HCL) acid.<\/p>\n 2. STRUCTURAL REPAIR Rout out cracks, faulty con-struction joints and other structural defects to a depth of 37 mm and a width of 25 mm. Apply a brush coat of Xypex Concentrate as described in steps 5 & 6 and allow to dry for 10 minutes. Fill cavity by tightly compressing Dry-Pac into the groove with pneumatic packing tool or with hammer and wood block. Dry-Pac is prepared by mixing six parts Xypex Concentrate powder with one part water to a dry, lumpy consistency.<\/p>\n NOTE: 3. WETTING CONCRETE Xypex requires a saturated substrate and a damp surface. Concrete surfaces must be thoroughly saturated with clean water prior to the application so as to aid the proper curing of the treatment and to ensure the growth of the crystalline formation deep within the pores of the concrete. Remove excess surface water before the application. If concrete surface dries out before application, it must be re-wetted. When a second coat (Xypex Concentrate or Xypex<\/p>\n Modified) is required, it should be applied after the first coat has reached an initial set but while it is still \u201cgreen\u201d (less than 48 hours). Light pre-watering between coats may be required due to drying. The Xypex treatment must not be applied under rainy conditions or when ambient temperature is below 4\u00baC. For recommended equipment, contact Xypex Chemical Corporation or your local Xypex representative.<\/p>\n 6. CURING A misty fog spray of clean water must be used for curing the Xypex treatment. Curing should begin as soon as the Xypex has set to the point where it will not be damaged by a fine spray of water. Under normal conditions, it is sufficient to spray Xypex-treated surfaces three times per day for two to three days. In hot or arid climates, spraying may be required more frequently. During the curing period, the coating must be protected from rainfall, frost, wind, the puddling of water and tem-peratures below 2\u00baC for a period of not less than 48 hours after application. If plastic sheeting is used as protec-tion, it must be raised off the Xypex to allow the coating to breathe. Xypex Gamma Cure may be used in lieu of water curing for certain applications (consult with Xypex<\/p>\n Chemical Corporation or your local Xypex representative).

\n\u2022 Xypex-treated concrete samples were pressure tested to a maximum 7 bars (230 ft.\/70 m water head) for 10 days. Test revealed that while 25 ml of water had penetrated the untreated concrete samples, zero ml had penetrated the Xypex-treated samples. Test specimens were then broken and showed water penetration to a depth of 15 mm on untreated samples but no measurable water penetration on the Xypex-treated samples.
\n\u2022 CSN 1209\/1321, \u201cImpermeability and Resistance to Pressurized Water\u201d, Institute of Civil Engineering, Technology and Testing, Bratislava, Slovak Republic
\n\u2022 Xypex-treated and untreated concrete samples were exposed to 1.2 MPa of pressure to determine water permeability. Results showed the Xypex-treated samples provided effective protection against hydrostatic water pressure. Treated and untreated samples were also sub-jected to contact with silage juices and various petroleum products (e.g. diesel oil, transformer oil, gasoline) at 14 kPa for 28 days. The Xypex-treated samples significantly reduced the penetration of these solutions.<\/p>\n
\n\u2022 Xypex-treated cylinders and untreated cylinders were ex-posed to hydrochloric acid, caustic soda, toluene, mineral oil, ethelyne glycol, pool chlorine and brake fluid and other chemicals. Results indicated that chemical expo-sure did not have any detrimental effects on the Xypex coating. Tests following chemical exposure measured an average 17% higher compressive strength in the Xypex-treated specimens over the untreated control samples.

\n\u2022 Against a direct flow of water (leakage) or where there is excess moisture due to seepage, use Xypex Patch\u2019n Plug then Xypex Dry-Pac followed by a brush coat of Xypex Concentrate. (Refer to Xypex Specification and Application Manual for full details.)
\n\u2022 For expansion joints or chronic moving cracks, flexible materials such as expansion joint sealants should be used.<\/p>\n
\n4. MIXING FOR SLURRY COAT Mix Xypex powder with clean water to a creamy consistency in the following proportions:
\n\u2022 For Brush Application
\n\u2022 0.65 – 0.8 kg\/m2
\n\u2022 5 parts powder to 2 parts water
\n\u2022 kg\/m2
\n\u2022 3 parts powder to 1 part water
\n\u2022 For Spray Application
\n\u2022 0.65 – 0.8 kg\/m2
\n\u2022 5 parts powder to 3 parts water (ratio may vary with equipment type)
\n\u2022 Do not mix more Xypex material than can be applied in 20 minutes. Do not add water once mix starts to harden. Protect hands with rubber gloves.
\n5. APPLYING XYPEX Apply Xypex with a semi-stiff nylon bristle brush, push broom (for large horizontal surfaces) or specialized spray equipment. The coating must be uniformly applied and should be just under 1.25 mm.<\/p>\n
\nNOTE: For concrete structures that hold liquids (e.g. reservoirs, swimming pools, tanks, etc.), Xypex should be cured for three days and allowed to set for 12 days before filling the structure with liquid.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row]<\/p>\n","protected":false},"excerpt":{"rendered":"
