Abbotsford, B.C. 
Roof surface was treated with the Xypex Concentrate DS-1 (by hand). 

DS-1 is a special dry shake formulation of Xypex Concentrate designed specifically for horizontal concrete surfaces such as parking decks and floor slabs.  Applied by hand or by mechanical spreader, DS-1 is trowelled into fresh concrete prior to finishing. 

DS-2 is used for concrete structures where increased abrasion resistance is required.

DS-1 and DS-2 must be bull floated into surface for maximum benefit.
Finish with regular finishing blades and trowels.
Aeration tank walls were pressure washed with a 2500 p.s.i. machine to proper profile and coated with one coat of Xypex Concentrate and one coat of Xypex Modified at 1.5 pounds per square yard.
