Krystol Internal Membrane™ (KIM)

JUMP TO

GENERAL DESCRIPTION

Krystol Internal Membrane (KIM) is a hydrophilic crystalline admixture internationally known for making exceptionally durable and watertight concrete. KIM contains advanced Krystol® technology, which drives a catalytic reaction using cement and water to grow a protective crystalline network throughout the concrete’s pores, capillaries, cracks, and micro-cracks. Long-term reactivity provides adaptive self-sealing and self-healing properties that counteract deterioration and allow concrete to maintain its integrity. KIM is non-toxic and meets all requirements of ACI 212.3R as a Permeability Reducing Admixture for Hydrostatic Conditions (PRAH).

APPLICATIONS & BENEFITS

APPLICATIONS

APPLICATIONS & BENEFITS
Read and distribute Application Instructions 1.11 (Cast-in-place concrete) or 1.21 (Shotcrete) before using this product. A prepour meeting with the general contractor, forming contractor, finisher, concrete supplier and materials testing engineer is strongly recommended. Treat construction joints and penetrations in accordance to Application Instructions 4.11-4.31 (as applicable). Dose KIM up to a maximum of 8 kg/m3 (13.5 lb/yd3) in consultation with an authorized Kryton representative. KIM is compatible with all cement types, supplementary cementitious materials (SCM’s), admixtures and fibers. Trial batches are required to determine actual plastic properties. Allow KIM to thoroughly mix at medium/high speed for minimum 1 minute per cubic meter/yard in the batch and a minimum of 3 minutes. Place and finish in accordance with ACI guidelines. Cure in accordance with ACI 308.1 guidelines.

Limitations
Concrete structures must be designed to resist all structural loads including all hydrostatic forces. Self-sealing is effective for static (non-moving) cracks. For dynamic (moving) cracks, use a flexible sealant. For moving joints, use an engineered expansion joint
