Building a raised paver patio takes some experience & expertise to insure a functional and creative paver installation. This particular brick paver patio was installed by a reputable local landscaper that obviously lacked the foresight & experience to accomplish this goal.
As a result of this poor paver capping, the pavers behind the brick caps settled all along the perimeter of the paver patio, paver steps, and sitting walls. The inexperienced landscaper did not use the right size paver to cap with so it would allow them to mitre cut nice & tight. This fear or neglect of cutting has now cost this customer aggravation and money to correct.
We removed all the old brick paver caps and lifted about 16" behind the wall to reset sunken paving stones through out the paver patio. We could NOT use the proper retaining wall cap units because they are 3 1/2" thick and the brick caps were only 2 3/8" thick. For us to install the proper retaining wall caps, we would either have to re lift ALL of the paver patio to reset the height or lower the modular retaining wall blocks. Both these options are more expensive than recapping the raised patio wall with a larger paving stone and cutting them in properly.
Remember to hire an interlocking brick paver specialist for your next brick pavers or retaining wall project.
