Small Raised Paver Patio & Steps Restored in Ann Arbor

Brick Paver Patio is Rebuilt to Restore Original Beauty & Function


On a weekly basis, we are rebuilding Brick Paver Patios to restore the original beauty & function that they were intended to provide.  This small raised pavers patio in Ann Arbor needed a complete rebuild restoration.

When giving an estimate on a paver patio restoration, we always provide cost options for the customer to consider.  In this particular project, a total patio rebuild restoration made the best sense for the homeowner.


The homeowner admitted to never performing any seasonal maintenance or addressing the settling of the wall blocks and paving stones the last few years.  Had the homeowner performed some simple routine maintenance and addressed the first signs of settling, they would not have the current cost for a total rebuild of this raised pavers patio.


My very experienced crew attacked this neglected raised pavers patio with precision and resolve.  The paver steps where re-leveled & re-glued. The raised patio wall blocks & caps were totally torn down and re-installed. Lastly, the paving stones where removed, cleaned, and re-installed in the same dimensions, shape, & design that the customer enjoyed so many years ago in the past. It takes alot more expertise to rebuild a pavers patio then to originally install from scratch.

With routine seasonal maintenance and attention to any settling in future years, this raised pavers patio will last a lifetime of enjoyment & function.  When we witness brick paver patios in this condition the major factor contributing to their demise is homeowner neglect.  Treat your brick pavers like any other outside maintenance need or project you address each Spring and the results will be spectacular.

Retaining Wall Repair needed quickly in Ann Arbor


Repair of Landscape Wall



We were needed recently to repair a Retaining Wall in Ann Arbor that was beginning to collapse. The corner of this retaining wall was beginning to separate and slide off it's bottom foundation. The homeowner had recently noticed further gapping of the blocks and leaning of the wall towards his front walk.  Time was of the essence and the modular retaining wall needed total reconstruction.

The homeowner was frustrated because the original landscape architect & contractor would not properly address the issues regarding this landscape retaining wall.  Because of my 27 years experience constructing & repairing modular retaining wall systems, I had some theories as to the reason this block wall had drastically settled.

From my visual inspection, I had noticed that the 90 degree corner of this retaining wall had failed miserably and some lower modular blocks had "slid" off the ones below them. This particular retaining wall system is Fendt's Keystone Old World Country Manor and requires a fiberglass pin system to hold the structure together.  These modular retaining wall blocks also have a hollow center that requires to be filled with gravel.

I had concluded from my visual inspection that these  2 key factors contributed to the failure of this retaining wall system.  As we disassemble this landscape wall, my conclusions were accurate. See the pictures to the right to see the poor installation of these retaining wall blocks.

The corners of modular retaining wall systems are the most important part of any large landscape walls.  They require extra reinforcement because the brunt of hydro static pressure & gravity can compromise the weakest part of any retaining wall construction. This retaining wall lacked the basic requirement of fiberglass pins to help secure the blocks in place. The landscape contractor choose to just "glue" the corner blocks. The result was a lower landscape block "sliding" off the foundation block below and allowing the pressure to push the retaining wall out.

As we tore down the complete wall due to excessive gapping, leaning, & settling, we also observed that none of the block's hollow centers & gaps were filled with gravel.  Filling all voids in a modular retaining wall system is required to give the wall additional mass.  Landscape wall systems are engineered with minimum specifications to help insure long-term performance. This particular retaining wall failed to meet 2 key installation specifications.

We disassembled the entire retaining wall from the top down. We re-leveled and recompacted the gravel base, reinstalled the bottom blocks to the correct level, and reconstructed the modular retaining wall blocks one-by-one, using the correct number & location of fiberglass pins and filled all voids with gravel. The finishing touch was to re-cap the wall and touch up the surrounding landscape.

We paid special attention to the corner of this retaining wall.  We replaced the small blocks the past contractor used and used the larger blocks in the retaining wall system so we could properly pin the units. We also constructed the corner using the "log cabin" method of overlapping the corner units as each row was stacked, pinned, filled, and backfilled. 

This retaining wall repair situation is very common in Ann Arbor. The landscape architect & contractor had a good design and good use of product, but the execution of installing was poor.  It does take some expertise & experience installing modular retaining wall systems properly. This particular landscape wall construction should have started and constructed from the corner out. It only took "one" block to slide out and destroy the performance of this very popular retaining wall application.

Small Brick Paver Jobs

Interlocking Paver Pad

We installed this small brick paver pad for a condo in Ann Arbor this week. I am often asked if we do small brick paver jobs....the answer is.. "We love small paver jobs!"

This brick paver customer just needed a small paver pad out his condo patio screen door to keep mulch & dirt from being tracked into his patio. We installed this 25sq.ft paver pad in about 2 hours. When you factor in loading time, drive time, and clean up. the whole project was about 3 hours worth of work.

There are several factors to keep in mind so the price of your small brick paver project will be reasonable. This customer followed my recommendations to keep the price below $300. Most landscape or paver contractors will do your small paver project at an inflated price.

First, I would allow the brick paver contractor to use a new paver they have left over in stock (make sure you are not getting any used pavers unless discussed) . Second, allow the pavers contractor to use any color or a mix of colors. Allow the contractor to lay out the dimensions so the saw cutting of the pavers is minimal or not needed. Allow the paver contractor to lose the excavated soils on-site and finally, allow the contractor to use your job as a "Plug Job". A "plug job" allows the contractor to fit the job in any day or time he has a "gap" in their schedule and they can "plug" you in. Often I will have a guaranteed completion date which may be a month or two out depending on time of year.

If you are flexible and not in an immediate rush, you can often get a good price on a small brick paver project. Most often brick paver contractors are your best choice because they have extra stock of pavers and are more efficient to make the project reasonably profitable.

Small Paver Patio Repair after 5 Years Installed!

This past week in Ann Arbor, I did a small paver patio repair on a raised brick paver patio & brick walkway I installed 5 years ago. I am proud to see the results of this paver patio and the customer is as ecstatic today as the time we installed this project. The client had been frustrated with the constant upkeep & cost of a wooden deck. After years of substantial costs & sweat equity to maintain this wooden deck, the customer searched for a better solution.

The solution was a low maintenance modular retaining wall & paving stone constructed paver patio. I used UNILOCK's Pisa 2 retaining wall system to construct the paver patio frame and steps while laying Olde Greenwich Cobble as the paving stones.

This paver patio was installed in 2005 and after some severe winter climates and frosts in Michigan, it has remained intact and beautiful. The only repair needed was raising the paver soldier course along the back of the modular retaining wall caps. I talk about this paver repair in a previous post called "Top Brick Paver Repairs".

One of the major reasons that this raised paver patio and paver walkway has remained so beautiful and functional is due to the diligence of the homeowner. Each Spring they have swept in paver joint sand. A couple of years ago, they began using polymeric sand which not only aides in preventing weed & grass growth in the joints, it also helps prevent any erosion due to rain & snow. The homeowner also checked the modular retaining wall caps each Spring to make sure they were not loose. I had left them a caulking tube of Paver Bond adhesive so after my warranty they could keep them fastened.

After I completed this brick paver project, I took the time to educate the customer on the yearly maintenance requirements and the signs of possible future paver repair. I talk to them about the pros and cons of sealing pavers, what to do about the landscape around the paver installations, what not to leave on the paver patio in the winter, and when to contact me if certain areas begin to settle.

The most important tip that I gave this client was to contact me when there are signs of the paving stone soldier course settling along the back of the modular retaining wall caps on the raised paver patio area.  It took 5 years but they diligently did.  This $150 paver repair of the soldier course will protect this raised paver patio from excessively settling to avoid wall settling and a more costly repair.

The result of a proper brick paver installation & design, educating the homeowner,the homeowner performing simple maintenance, and a touch-up brick paver repair has been a beautiful & functional paver patio & walkway that this homeowner and contractor can appreciate. I am proud of this homeowner and more brick paver installations would remain this perfect if all involved would take pride in the effort and cost of paving stone installations.
