Waterproofing systems for sealing of pressurised and non-pressurised water, horizontal water barriers, anti-mould-system


3.01 - KÖSTER KD 1 Base

Fast setting, mineral sealing slurry with high resistance to aggressive ground moisture and pressurised water. Used in combination with KÖSTER KD 2 and KÖSTER KD 3 Sealer against pressurised, flowing water.


3.01 - KÖSTER KD 2 Blitz Powder

Highly reactive powder with extremely short setting time. Active leaks are stopped within a few seconds with the dry powder. Used in combination with KÖSTER KD 1 Base and KÖSTER KD 3 Sealer for waterproofing against pressurised water.


3.01 - KÖSTER KD 3 Sealer

Water-thin silicifying liquid. The active ingredients penetrate deeply into the substrate and form water insoluble compounds. Thus, the pores are plugged and permanently waterproofed by the continuing mineralization. Used in combination with KÖSTER KD 1 Base and KÖSTER KD 2 for waterproofing areas against pressurised water.


3.01 - KÖSTER KD System

The complete KÖSTER KD System in one package.


3.02 - KÖSTER NB 1 "Fast"

Fast setting, deep crystallizing, mineral surface coating for waterproofing mineral substrates, resistant to pressurised water, can be used for positive and negative side waterproofing on masonry and concrete as fast waterproofing system.


3.02 - KÖSTER NB 1 Flex

KÖSTER NB 1 Flex is a latex based dispersion which is intended as a mixing liquid for KÖSTER NB sealing slurries. It has an elastifying effect, it improves the adhesion to the substrate and it prevents the premature drying out of the fresh slurry.


3.02 - KÖSTER NB 1 Grey

Watertight (>130 m water head), mineral surface coating with subsequently crystallising agents. Waterproofing layers made of KÖSTER NB 1 Grey possess excellent pressure and abrasion resistance. Approved by the building authorities and tested in accordance to the potable water guidelines. For waterproofing of areas in new buildings and in restoration.


3.02 - KÖSTER NB 2 White

Mineral surface coating for waterproofing mineral substrates which is resistant to pressurised water. Waterproofing layers made of KÖSTER NB 2 possess a high pressure and abrasion resistance. For waterproofing areas in new building and in restoration.


3.02 - KÖSTER Restoration Slurry

Surface coating, resistant to sulphates and pressurised water. The material possesses high mechanical strength and is resistant to chemical and mechanical stresses. For waterproofing basements from the inside.


3.03 - KÖSTER NB Elastic 1C White

Single component, light coloured, elastic coating which is resistant to pressurised water. KÖSTER NB Elastic 1C White is crack bridging and abrasion-proof. It is suited for abrasion proof waterproofing of areas in danger of cracking.


3.03 - KÖSTER NB Elastic Grey

2-component, elastic coating, resistant to pressurised water. KÖSTER NB Elastic Grey is crack bridging up to 2 mm and abrasion proof. For wear resistant waterproofing of areas at risk of cracking.


3.03 - KÖSTER NB Elastic White

White, 2-component, elastic coating, resistant to pressurised water. Ideal for waterproofing visible surfaces. KÖSTER NB Elastic White is crack bridging, abrasion-proof and suitable for wear resistant waterproofing of areas at risk of cracking. Radonproof.


3.038 - KÖSTER Elastic Roof

KÖSTER Elastic Roof is an elastic, crack bridging, and solvent-free waterproofing material for dry and slightly damp substrates. It is free of VOCs (Volatile Organic Compounds), free of Polyurethanes, and free of Isocyanates. The fast drying foil-like coating is highly flexible, watertight and water vapour permeable. The foil is resistant against ageing, hydrolysis, UV-rays, frost and de-icing salts. The white color reflects heat. Since KÖSTER Elastic Roof sticks to itself, the application is easy and seamless.


3.04 - KÖSTER Mautrol® Liquid Sealant

Very thin fluid, deeply penetrating silicifying concentrate for waterproofing against rising damp. It reacts to water insoluble and water-repelling compounds which also have a solidifying effect on the building material.


3.04 - KÖSTER Mautrol® Liquid Sealant Cartridges

Silicifying concentrate in ready to use cartridges for waterproofing against rising damp. For pressureless injection into masonry.


3.05 - KÖSTER Mautrol® Borehole Suspension

Sulphate-resistant, solidifying mortar with silicifying properties. The mortar is low viscous and capable of flowing. It can penetrate into the finest voids and cracks.


3.06 - KÖSTER Mautrol® 2C

Two-component, building material solidifying, solvent-free, low viscous injection fluid on the basis of siliconates and esters. It can be applied in strongly moisture penetrated construction ­members for waterproofing against rising damp without ­previous drying. The material is applied by pressurised injection.


3.06 - KÖSTER Mautrol® Flex 2C

2-component, solvent-free, water dilutable injection liquid on acrylic basis on acrylic against rising damp. Suitable for application even in very damp construction members without draining them beforehand.


3.08 - KÖSTER Crisin® 76

Very thin-fluid synthetic resin for waterproofing against rising damp even in case of high moisture and salt contents of the masonry. Due to its very low density and due to its surface tension which is considerably lower than that of water, KÖSTER Crisin 76 displaces the water from the capillaries. After full cure, KÖSTER Crisin 76 remains elastic and it does not rot. Density: 0.76 g/cm3, viscosity 1.2 mPa · s. KÖSTER Crisin 76 is resistant to all aggressive media which are usually encountered in masonry such as acids, alkalis and salts, during application as well as after full cure. Tested according to WTA guidelines.


3.08 - KÖSTER Crisin® 76 cartridge

Dissolved synthetic resin in a cartridge for waterproofing against rising damp even in case of high moisture and salt contents.


3.14 - KÖSTER Waterstop

Fast setting, swellable plug and repair mortar. An intensive contact between existing substrate and the mortar is achieved. It is suited to plug active water leakages.


3.15 - KÖSTER AMS Liquid Film

Solvent-free dispersion coating that reduces vapour transmission. Component 1 of the KÖSTER Anti Mould System for combatting and preventing mould infestation in living areas on a purely physical basis, free of fungicidal poisons.


3.15 - KÖSTER AMS Special Plaster

Condensate-reducing capillary-inactive special plaster. Component 2 of the KÖSTER Anti Mould System for combatting and preventing mould infestation in living areas on a purely physical basis, free of fungicidal poisons.Consumption


3.15 - KÖSTER AMS System Pack

System for combatting and preventing mould infestation in living areas on a purely physical basis, free of fungicidal poisons.
