Xypex Megamix II + Bio-San is a resurfacing mortar specifically designed for the restoration of deteriorated concrete surfaces caused by microbial induced corrosion, abrasion/erosion and chemical attack. It is formulated for ease of application, superior bond, low shrinkage, high strength and resistance to microbial, acid and sulphate attack.

Megamix II + Bio-San contains bioactive mineral solids which fix permanently within the repair mortar matrix impairing bio-film formation, thus limiting microbial induced corrosion of the repaired surface in sewer environments.

It significantly extends the life of sewer and waste water infrastructure by inhibiting the growth of acid causing sewer bacteria such as Thiobacillus that cause MIC (microbial induced corrosion).

In most applications, such as manhole resurfacing, Megamix II + Bio-San can be used to replace epoxy linings and calcium aluminate repair mortars.
