This past week we performed a brick paver patio repair, cleaning and polymeric sanding on a paving stone patio in Ann Arbor. As you can see in this pic, the paver patio was in an extreme need of cleaning. The abundance of moss was the direct result of moisture and shade.
We performed a brick paver repair by lowering the paver edge restraint that had raised from frost. The raised edge restraint was not only unsightly but it created a dam around the paver patio and did not allow water to run off the paving stones. Therefore creating a lot of moisture on the paver patio and allowing moss to thrive combined with the shade in this area.
Reinstalling the plastic edge restraint is not easy. Grass & roots grow around the edge restraint and the spikes rust and make it very hard to remove. We removed @18" of sod around the paver patio so the client could install enviro mulch or stone mulch. We reinstalled the paver edge restraint properly by making sure the top lip was at least 1" below the top edge of the paving stone border.
The cleaning of this paver patio required an aggressive approach to power washing. We spent over 2 hours at a high PSI blowing out ALL the paver joints freeing them of dirt, moss, and weeds. There is a need to be careful not to wash out the bedding course under the paving stones. This may result in paving stones sinking. After the paver joints where free of debris, we widen our spray nozzle and cleaned the individual paving stones to remove dirt, stains, and mold.
When the paving stones and paver joints were dry, we returned to sweep in polymeric sand in all the paver joints. Keeping up each Spring season with polymeric sand will almost eliminate future accumulation of dirt in the paver joints which allows weeds to fester. Moss on the other hand can still grow on top of paver joints and paving stones. Moss can be easily controlled by keeping a spray bottle mix of clorox bleach & water. Also, moss can be sprayed off fairly easy with a traditional hose & spray nozzle on jet stream.
Brick Doctor Bill was able to help this brick paver patio regain its function and luster. We spent the time to educate the homeowner on the easy & timely brick paver maintenance steps to keep their paver patio at it's best. Another satisfied client in Ann Arbor!
