Basement Tanking & Internal Waterproofing

Platinum Lime Inhibitor is specifically formulated for the control of primary and secondary efflorescence in concrete mixes.

Platinum Lime Inhibitor is applied to concrete surfaces prior to the installation of a 'Type C' Cavity Drain Membrane System to prevent the ‘leaching’ of free lime from the concrete.

Primarily designed to be used on new concrete structures, Platinum Lime Inhibitor should also be used to treat cut recesses in existing concrete slabs.

Typical Applications

Concrete floors newer than 12 months. The whole of the concrete slab or raft as well as the recess formed ready for Drainage Conduits / Channels.

Walls - 200mm up the wall from the floor, or where a ‘kicker’ has been formed to a concrete wall, apply from the floor up to 200mm above the kicker.

Concrete floors older than 12 months - The recess cut into the concrete ready for Drainage Conduits / Channels as well as 200mm either side of floor construction or movement joints.

Underpinned properties require application to 200mm either side of the joints. Dry-packed areas should be sealed with a cement-based tanking product and then the tanking treated with Platinum Lime Inhibitor
