To increase the life and improve the stability of concrete Geosynthetic Clay Liners can be installed under all reinforced concrete slabs. They are used extensively for concrete waterproofing in a wide range of commercial and civil applications, including:

• Basement waterproofing
• Wall tanking
• Lift pits – the waterproofing membrane of choice to keep sub-basement lift pits dry
• Grain storage facilities
• Roof decks
• Podium decks
• Tunnels
• Waterproofing utility services

Geosynthetic Clay Liners are widely used to waterproof basements and horizontal foundation surfaces to ensure buildings stay dry. Bentonite clay liners with its special properties of low permeability, high internal shear strength are ideal for waterproofing under slabs, behind concrete walls and underground tunnels. Sodium bentonite’s swelling action self-seals small concrete cracks caused by ground settlement, concrete shrinkage or seismic action.
