Innospec’s MILLIFOAM® CLS foaming agents create controlled, stable foams for lightweight & aerated cementitious materials (mortar, concrete, grout), with a focus on improving Controlled Low Strength Materials.

Controlled Low Strength Materials (CLSM) are a kind of self-compacting and self-levelling concrete which can be applied quickly, efficiently and cost-effectively within a range of construction areas (backfilling, pavement bases, void filling, utility bedding).

MILLIFOAM® CLS are anionic, foaming and air-entraining agents specially formulated for CLSM, but which can also be used in other lightweight concretes.

The choice between MILLIFOAM® CLS 100, 200, and 380 affords the user several benefits, summarised below. These include excellent foaming properties, high workability and tolerance to hard water and electrolytes.
