Clean paving stones in Saskatoon. Concrete paving stone, brick paving stone, poured concrete, and natural paving stone all need to be cleaned thoroughly before a sealer can be applied. We use specialized cleaning equipment in conjunction with our specially formulated cleaners to penetrate deep inside the surface pores releasing ground-in dirt and contaminants. The process works without damaging or discolouring the pavers. It also brightens colours and enables the sealer to better penetrate the paver. Remove dirt, grime, grease, rust, paint, leaf stains & more.
