Brick Paver Patio Cleaning

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!

Brick Paver Sealing is for the Brick, NOT the sand in the joints!

After completing a brick paver sealing of a paver patio today, the customer said while handing me my check, "so I will not get any weeds, right?". It drives me crazy that customers are only concerned with the sand in the joints being sealed and not the patio stones. Sealing pavers is for the brick, NOT the sand!

Today's customer never commented on the enhanced color and appearance of the brick paver patio. They never asked any questions regarding the long term performance of the paving stones surface or protection from natural elements. They were never concerned about the cost or frequency of an approved brick paver sealer application. They were only concerned during my estimate and my completion of services about a 100% guarantee of NO WEEDS!

I usually have to slowly explain to potential clients that sealing of pavers is for the enhanced appearance and performance of the concrete paver. But as predictable, customers only hone in on the sand in the joints. They believe that the brick paver sealer is for sealing the joints, therefore making the sand permanently hard like mortar so weeds can not grow. It is true that the paver sealer will typically flow into the joints and temporarily harden the sand. But as the interlocking brick pavers expand or heave due to winter frost, these joints will absorb the pressure and loosen. Snow, ice, rain, and wind will eventually erode the sand and create opportunities for weed seeds to germinate.

I could have saved this customer 100's of dollars if the paver joints were their only concern. I could have simply used some brick paver polymeric sand in all the paver joints to harden for the season. Simple touch ups of paver joint sweeping each Spring will keep joints filled and hardened to deter any chance for a weed seed to establish. I always tell customers that the number one reason to seal brick pavers is for aestheitc values of the paving stones, NOT for the sand in the joints!
