Crystalline Waterproofing Compound

Crystalline Waterproofing Compound

KR CWC Crystalline Waterproofing Compound is capillary waterproofing formulations of possessive mixtures of quartz sand, chemicals and cement. The chemicals contained available in crystalline waterproofing materials need the presence of moisture in order to set off a chemical response from within the concrete matrix. When combined along with "free lime", these chemicals type long sequenced complexes that penetrate and crystallize deep into the capillaries of the concrete removing the migration of water. Independent checks present penetration up to 50mm in 28 days. The crystalline procedure is incessant as long as moisture is available in the concrete, significantly eliminating the natural porosity of concretes by filling small cracks and voids generated by shrinkage. The concrete is yet able to breathe as the crystalline doesn't produce a vapor barrier. If no dampness is available, the crystals will lie inactive until humidity reappears and then will reactivate so as to seal the cause of the leakage.

KR CWC is a premium, rapid-setting repair and plugging material specifically designed to stop leaks in concrete walls, pre-cast concrete, floors, cisterns, bulkheads, etc.

KR CWC is applied as a slurry coat on vertical interior or exterior (CIP) concrete or (CMU) block structures to create a waterproofing barrier from within the substrate. It can be applied by "broadcasting" the dry powder onto horizontal concrete surfaces at the time of initial set and power or hand floating the powder into the green concrete. Once the reaction has taken place and the formulation has crystallized, these coatings are highly resistant to salts, alkalis and seawater. Because of the density of the crystalline chain, the concrete is able to withstand mildly acidic conditions to provide protection in waste-water treatment plants as well as superior protection against frost damage and may also be used in sealing the joint between new and existing concrete.

KR CWC is applied in mortar consistency to make coves and for filling reglets at construction joints. It is also used to repair honeycombing, cracks, filling of form tie holes and cold joints and is used in conjunction with

KR CWC is used as a rendering for brick masonry and stonewalls. It is supplied as a ready-mixed material, adding only water to make the material ready for use.

Basic Uses :-

Few products in the waterproofing industry offer the total protection to the concrete itself that KR CWC. Waterproofing Systems provide. Where moisture is present, there is always the danger of damage not only to the concrete but to the steel as well as interior finishes. Crystalline products, when applied to inside or outside surfaces, integrate and combine with the concrete from within thus forming a barrier which cannot easily be damaged. No special below-grade protection is necessary. The crystalline products tolerate water so there is no need to continually dry the surface before application, unlike most asphaltic, bitumen or solvent based resin systems. Crystalline Waterproofing Systems provide fast, economical waterproofing for foundation walls and floor slabs, suspended or in-ground pools, and protect against spalling due to oil, salt and freeze/thaw action in parking garage floor applications.

Packaging : 25 kg bag.
Colour : Grey

Installation

All surfaces to receive KR CWC products must be clean and free from oil, grease, paint, loose dust and Laitance. Horizontal surfaces should not have curing agents or hardeners applied prior to the crystalline product application. Rout out and repair all cracks larger than 1mm in width.Ensure all vertical concrete surfaces are waterblasted as moisture must be present in the capillaries prior to the crystalline waterproofing application. Dry broadcast KR CWC on horizontal surfaces. Mix one part of KR CWC to one part water by volume to produce a mixture suitable for brushing or spraying. The mixture should be used up within half an hour, after which time it starts to thicken. On no account add extra water to restore workability. Install slurry coats in two passes with the second being applied while the first is still tacky. Intermittent fogging with water the day after application is recommended. Surfaces may be backfilled 24 hours after application. Backfilling material should be wet down adjacent to the walls.

KR CWC Crystalline Waterproofing Products can also be used to completely stop leaks from the inside of any concrete or block structure, even against extremely high water pressure. All concrete deficiencies such as faulty and leaking construction joints and cracks, cold joints and honeycombing must be routed out and cleaned thoroughly. If necessary, a plastic or rubber tube may be inserted to control the flow of water. The routed out area is then coated with KR CWC slurry. Fill the remainder of the cavity with (1:1) cement: sand, mortar, coating the final surface with KR CWC. Small areas can be filled with KR CWC.
