Davco® K11 Moisture Barrier

An alkali-reactive waterproofing product based on alkali resistant synthetically modified cement. The Davco Lanko K11 waterproofing concept is based on the crystallisation process. Davco Lanko K11 compounds combine with free water and other elements in the substrate to produce a waterproof membrane. The unique and highly effective components of the Davco Lanko K11 systems chemically react within the pores and capillaries upon exposure to the moisture and the elements. This chemical reaction initiates the formation of the crystalline structure within the pores and capillaries, to become an integral part of the structure and block the passage of water. Davco Lanko K11 is a brush or roller applied, Portland cement based system for waterproofing concrete and masonry through the crystallisation process. Davco Lanko K11 waterproofs the positive side or the negative side of the substrate. Following proper application, active water pressures force the crystal forming chemicals deeper into the sub-surface capillaries and pores to form a monolithic bond and become an integral part of the structure.

Usage

Davco Lanko K11 is applied to interior or exterior below grade surfaces and between horizontal structural slabs and toppings to protect against hydrostatic water pressure. These surfaces include concrete, concrete block, brick and shotcrete. Davco Lanko K11 Can be used in a variety of installations, some examples being: subway Stations; swimming pools; mines; fish hatcheries; tunnels; solar water tanks; aquariums; cooling tower basins; elevator pits; basements; planters; floors; manholes; sewage treatment. Davco Lanko K11 is approved as a mineral waterproofing layer for the protection of buildings against ground moisture, i.e. ground water under pressure (rising damp etc.) and against surface water, rainfall, seepage, and in general against water under a low hydrostatic pressure. It is also approved for the internal coating of potable water containers up to a height of 5m, on all sound mineral substrates.
