Krysta Leakproof

• Crystalline systems use available water/moisture to grow millions of needle like crystals in the micro-cracks/voids/pores/capillaries inside the concrete matrix & closes any pathways for the moisture that can damage the concrete from any directions. It can self-seal hairline cracks up to 0.5mm even after the original construction & makes the concrete itself the water barrier even under high hydrostatic pressure up to 16 bar head.
• It is a permanent waterproofing method & becomes integral part of the concrete. Whenever any form of water/moisture enters the concrete, be it from new cracks or pores, the crystalline technology triggers new crystals to grow and seal the pores inside the concrete & hence water molecules/ moisture & harmful chemicals like chlorides and sulphates cannot penetrate through the concrete & it also protects the concrete against carbonation & reduces chloride diffusion & it also protects reinforcing steel from corrosion, but it allows the concrete to breath.
• Crystalline contains no VOC’s and environmental friendly & can be completely recycled when demolition occurs & waterborne contaminants are not present in the concrete, and petroleum-based materials are not left behind to leach into soil. Since it is non-toxic, it is safe for potable drinking water applications
• Increases the compressive strength of the concrete by 10-12% as it makes the concrete denser by plugging all the micro-pores & capillary tracts by crystal formation.
• When crystalline admixture is added to concrete or mortar, it undergoes chemical reaction that causes long, narrow crystals to form, filling the pores, capillaries and hairline cracks of the concrete mass. As long as moisture remains present, crystals continue to grow throughout the concrete, reaching lengths of many inches over time. Once the concrete has cured, the crystalline chemicals sit dormant until another dose of water (such as through a new crack) causes the chemical reaction to begin again.

For small mixes, add Krysta Leakproof compound to the aggregates and mix for 2-3 minutes prior to adding cement and water.

For plant mixed material add Krysta Leakproof compound to 65-75% of the pre-batches water and mixing for 2-3 minutes prior to adding the remaining batched ingredients and mix 4-6 min in accordance with standard practice.

In transit mixer, Krysta Leakproof compound is dispersed in water and add to transit mixers on site just prior to placing. The minimum mixing time is 4-6 minutes at agitating speed.

The crystalline system for concrete waterproofing is substantially different from traditional barrier products (cementitious membrane, bitumen, acrylic, siloxane, etc).

• It creates a crystalline structure deep within the pores and capillary tracts of the concrete mass to prevent the penetration of water and aggressive chemicals.
• It is not dependent on surface adhesion to achieve its waterproofing effect. It is resistant to extreme hydrostatic pressure.
• It will seal hairline cracks up to 0.5 mm.
• It is not subject to the deterioration problems encountered by membranes.
• It is permanent and reactivates whenever water is present.

• It does not require a dry surface; in fact, a wet surface is necessary.
• It does not require dry weather to be applied.
• It does not require costly surface printing or levelling prior to application.
• It cannot puncture, tear or come apart.
• It does not require protection during backfilling or during placement of steel, wire mesh or other materials.
• It can be applied on either side of a concrete surface - the negative or the positive (water pressure) side.
• It does not require sealing, lapping and finishing of seams at corners, edges or between members.
• It is less costly to apply than most other methods.
• It seals the penetration of the water from every direction unlike membranes, which are basically pore blockers that block the pore structure of the concrete and keep water from penetrating via the top surface.
