Megamix I
Megamix II
Megamix II + Bio-San

Megamix I & II is a repairing mortar specifically for the waterproofing and resurfacing of deteriorated concrete surfaces, whereas Megamix II + Bio-San is specifically formulated for restoration of concrete damaged by microbial induced corrosion, abrasion/erosion and chemical attack.

Xypex Megamix I is a thin parge coat for the waterproofing and resurfacing of vertical masonry or concrete surfaces, as a cap coat for Xypex Concentrate, or as an architectural rendering. Megamix I is a unique blend of Portland cement, treated silica sand, fibers and proprietary chemicals. It is mixed with Xycrylic Admix to produce enhanced bond. Megamix I is applied by brush or trowel up to a thickness of 3/8 in. (10 mm).

Xypex Megamix II is a thick repair mortar for the patching and resurfacing of deteriorated concrete. Megamix II has been specifically formulated to produce superior bond, low shrinkage, chemical durability and high strength. It is a one component mortar and can be either sprayed or trowel applied at a thickness of 3/8" - 2" (10 - 50 mm).

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.
