WATERPROOFING COMPOUNDS
Hind Crystal Seal
CRYSTALLINE CAPILLARY WATERPROOFING FOR CONCRETE AND MORTAR.
DESCRIPTION
Hind Crystal Seal is a capillary waterproofing formulation of proprietary blends of moisture active chemicals, quartz, sand and cement. The chemical contained in Hind Crystal Seal formulations requires the presence of moisture for the chemical reaction to take place and in combination with the “free lime”, the chemical in Hind Crystal Seal forms long chain complexes which crystallizes in the capillaries. It conforms to IS: 2645-2003 & ACI 212.3R -2010.
USES
Hind Crystal Seal protects concrete and mortar making it 100% waterproof. It improves the adhesion between top coat and concrete or mortar. It is used for waterproofing of water reservoir, water tower, tunnels, dams, canals, concrete pipes, water treatment plant, sea wall, bridges and decks etc.
ADVANTAGES
- Ready for use only by mixing with water.
- Can be applied on damp concrete surface with no standing water.
- Non-toxic and can be applied on Concrete storage tank used for potable water.
- Cost effective waterproofing system.
- The crystallization reaction between Hind Crystal Seal with free lime and Calcium hydroxide in cement will form crystal to fully block the capillary in the concrete and mortar. It gives a total and permanent waterproofing to concrete structures in the presence of moisture.
- Can be applied to both positive and negative side protection of water retaining and underground structures.
APPLICATION
It has to be ensured before application that all concrete and mortar surfaces are clean free from dust, laitance, oil and grease. The surfaces to be pre-wetted, so that it is completely saturated. Hind Crystal Seal is to be applied on damp surfaces and there should be no standing water. Hind Crystal Seal 10kg (One bag) is to be mixed with 3-3.5 Litre of clean water for 3 (three) minutes using a slow speed mechanical mixer (60 rpm) until a uniform homogenous mix is obtained. Use brush or roller for application. We recommend 2 coats to be applied in interval of 3-4 hours to give better results. Hind Crystal Seal is a cementitious based products, and the treated surface with Hind Crystal Seal is to be properly cured by covering it with damp cover or moist curing for at least 5-7 days. Hind Crystal Seal can be applied immediately on new concrete surface as soon as the formwork has been removed.

Hind Crystal Seal (I)
CRYSTALLINE INTREGRAL WATERPROOFING ADDITIVE FOR CONCRETE AND MORTAR
DESCRIPTION
Hind Crystal Seal (I) is an unique formulation of crystalline powder additive for concrete & mortar. The active chemicals in the compound reacts with the moisture in fresh concrete and by products of cement hydration resulting to catalytic reaction to yield non-soluble crystalline formation sealing the pores and capillary tracts of the concrete permanently and also prevents ingress of water and other liquids from all direction. It conforms to IS: 2645-2003 & ACI 212.3R – 10.
USES
Hind Crystal Seal (I) protects concrete making it 100% waterproof. It is used for waterproofing of water reservoir, basements, foundations, water tower, tunnels, subways, swimming pools, parking lot, dams, canals, concrete pipes, water treatment plant, sea wall, bridges, decks and any concrete mix requiring waterproofing.
ADVANTAGES
- Ready for use only to be added to concrete at the time of batching.
- It is non-toxic and free from chloride.
- Protects concrete from water penetration under hydrostatic pressure or capillary absorption.
- Possess crack sealing characteristics
- Reduces Sulphate attack.
- Effective from both positive and negative water pressure.
- Cost effective waterproofing system.
- When added to concrete the compressive strength is not reduced.
- Low Dosage and economical.
APPLICATION
Hind Crystal Seal (I) should be added to concrete at the time of batching subject to the various type of the batching plant and operation. The following process is recommended for best results. After batching of Coarse aggregates, Fine aggregate, Cement and mineral admixture, Hind Crystal Seal (I) is sprinkled and dry mixing is carried out to get an uniform dry mixture. Finally gauging water with plasticizer is added and mixing is continued to get even consistency of the mix. Hind Crystal Seal (I) should not be added to gauging water and it is not recommended.
It is always advisable to carry out trial mixes to produce concrete and properties such as workability, setting time and compressive strength is achieved as per requirement. In hot weather conditions, addition of Hind Crystal Seal (I) into concrete accelerates the setting time of concrete. Curing to be carried out as per standard practice for concrete produced by addition of Hind Crystal Seal (I) .
