SAB Cristal 410 ConcentrateDescription

SAB 410 Cristal Concentrate is a waterproofing and protection system for concrete constructions. SAB 410 Cristal Concentrate works through internal crystallization based on special chemicals, cement and sand. SAB 410 Cristal Concentrate penetrates deep into the pores, the capillaries and shrinkage cracks and forms crystals who block the penetration of water. Independent of a negative or positive water pressure on the treated surface, SAB 410 Cristal Concentrate forms crystals and blocks the penetration of water.

In the absence of water, there is no reaction and the chemicals remain present in a “sleeping” state. When contact with water occurs, the reaction starts again and the chemicals penetrate further. This process continues until all active ingredients of SAB 410 Cristal Concentrate have participated in the crystallization process.

Applications

SAB 410 Cristal Concentrate is applied to concrete and cement structures where liquidwater needs to be kept in or kept out.

Examples: reservoirs, water treatment plants, aquariums, tunnels, foundations, underground structures, sewers, industrial processing plants, parking decks, road decks and all structures to be waterproofed and protected against chemical degradation.

Properties of SAB 410 Cristal Concentrate

• Barely reduces vapour permeability.• Penetrates in depth and makes capillary ducts and shrinkage cracks (up to 0.25 mm wide) watertight.• Can be applied to the water or facing side (e.g. exteriors of swimming pools, cellar interiors).• The water-tightness and chemical resistance remain, even where there is damage to the surface.• Easy to apply.• No protection needed for the application of filler or other products• Can be applied both to fresh and old concrete.

• Water-tightness: concrete with two layers of SAB 410 Cristal Concentrate (0,8 kg/m²/layer) is completely watertight after4 days (Magnel Laboratory report for 2001/056 – KA/MS concrete study).• SAB 410 Cristal Concentrate is resistant to frost-thaw cycles in accordance with NBN B05-203 (Magnel Laboratory report for 2000/630 – KA/CM concrete study).• Chemical protection: the SAB 410 Cristal Concentrate layer is resistant to thawing salts, sulphuric acid and hydrochloric acid for at least 35 days (Magnel Laboratory report for 2000/630 – KA/CM concrete study).• Concrete treated with SAB 410 Cristal Concentrate bridges over cracks (BECETEL expert’s report n° 5247).• No special after-care required except in the event of extremely high temperatures and low humidity.• Non-toxic (compatible with potable water applications).• Consumption: 1,6 kg/m² in two layers.• Minimum processing temperature: 5°C.• Shelf life: 12 months after production date in original, unopened and undamaged packaging, stored in a dry place with temperatures between +10°C and +30°C.

General instructions for the application of SAB 410 Cristal Concentrate

1 Preparation of the surface• The surfaces to be treated (concrete, concrete blocks, cement plaster) must be in good condition and free of dirt, earth, concrete milk and other products which could adversely affect the SAB 410 Cristal Concentrate adhesion, penetration or effect.• Roughen very slippery concrete surfaces with sand or water jets. The surface must be porous.• Grind cracks, bigger than 0,25 mm, to a depth of 2 to 2,5 cm.• Remove poor concrete until sound concrete is reached.• Slightly wet the surface before applying SAB 410 Cristal Concentrate.Water must be present in the concrete for the

SAB 410 Cristal Concentrate chemicals to penetrate well.

2 Mixing of SAB 410 Cristal ConcentrateApplication with a brush: Mix 7 to 8 litres of water with 25 kg ofSAB 410 Cristal Concentrate Application with a spray-gun: Mix 8 litres of water with 25 kg of SAB 410 Cristal Concentrate (depending on temperature and device) SAB 410 Cristal Concentrate has to be mixed to the consistency of a thick latex paint. Mix the substance frequently during the processing. Only prepare as much material as can be processed in 35 minutes.3 Applying SAB 410 Cristal Concentrate• Apply SAB 410 Cristal Concentrate using a brush or spray-gun.• Apply SAB 410 Cristal Concentrate to wet concrete in two layers

with a consumption of approximately 1,6 kg/m².

Hardening

No measures are required to promote hardening, except in the event ofhigh temperatures and low humidity. In the latter case, after applicationof SAB 410 Cristal Concentrate the surface has to be slightly wetted assoon as the SAB 410 Cristal Concentrate is sufficiently hard. Wetting thesurface once to three times on the first day is usually adequate.

PackagingSacs of 25 kg.

Precautionary measures and safety recommendations

• SAB 410 Cristal Concentrate is alkaline.• Long-term contact can irritate the skin, therefore use rubber gloves, boots and protective clothing when mixing and applying.• Use safety glasses when spraying and applying above the head.• SAB 410 Cristal Concentrate’s effect on the skin can beneutralized by washing the skin with household vinegar thinned with water.• In the event of contact with the eyes: rinse thoroughly for at least 10 minutes and consult a doctor.• Protect the fresh SAB 410 Cristal Concentrate layer against being dried out too quickly by the sun and wind.• SAB 410 Cristal Concentrate is not toxic
