Stonework Restoration and Patio Repair

by Dwayne Regehr

Although pavers are generally one of the lowest maintenance options for your yard, they do sometimes fall into disrepair. If your driveway or patio is made from concrete pavers, you are in luck – they are one of the easiest construction materials to fix

Pavers are uniformly sized and shaped bricks. This means a small area of a patio or driveway can be removed and re-installed in a seamless repair. If individual bricks are stained or damaged to the point that they need to be replaced, no problem, just replace them with new bricks. Try that with a poured concrete patio, walkway or driveway!

Let's say your poured concrete driveway has sunk and it's all cracked up. You can hire someone to pump grout under your driveway to level it with your garage slab, but then you are left with dozens of holes in your driveway filled with plugs, and of course cracks will never disappear.

Brick patios rarely fail if installed properly and high quality materials were used. But like proper installation, repair requires an understanding of how the concrete paver system works. Repairs can be as simple as lifting a few bricks and leveling them with additional base material, or in extreme cases, may require a the removal and reconstruction of the patio base.

If your patio needs work, we can help you diagnose the problem and come up with a cost-effective repair plan.

Types of failure

  • Wavy surface
  • Sunken surface
  • Rutting of surface
  • Separation of bricks
  • Sinking edges
  • Loose or broken bricks
  • Discolored or stained bricks

Causes of patio problems

  • Poorly compacted base. Proper compaction is critical. It increases the bearing capacity of the base stone and prevents future settling.
  • Insufficient base depth. The depth of the base stone must match the intended purpose. Patios require 6" base depth, driveways require 12" or more.
  • Wrong base material. A well graded, non-organic material such as 3/4" down limestone is ideal for patios. Other forms of gravel or A-base are less suitable. Pea gravel or other round stones remain fluid and do not compact and so they won't work well at all.
  • Inferior pavers. Pavers that will last are made with a carefully monitored cement/stone mixture. They're built with consistent compressive strength and quality. As a Winnipeg company, we're proud to say that Canadian-made pavers are subject to more rigorous testing than American-made bricks, so be cautious of the "great deals" to be found at big box stores south of the border.
  • Poor installation technique. There are many chances to take shortcuts in the installation of a patio, but unfortunately, not without compromising the final result. At Earthworks, we follow industry best practices, we've refined our construction methods over the last 20 years and can now offer a 5-year guarantee on all patios and retaining walls that we're really proud of.
  • Lack of edge restraints. Since a concrete paver patio is composed of hundreds of small units, a high quality edge restraint is important in keeping the pavers tight. Inferior edge restraints or insufficient spikes to hold it in place will allow pavers to separate over time.
  • Loss of joint sand. Until about 10 years ago, dry sand was used to fill the joints between bricks. Sand between bricks is crucial for creating the interlock between pavers. But the dry sand that was formally the industry standard was vulnerable to wind and rain and needed to be topped up on a regular basis. Fortunately, the switch to polymeric sand in recent years has eliminated the loss of joint sand and has improved resistance to weeds and insects.
  • Freeze/thaw cycle or changes in soil moisture content. Anything that causes the clay sub-soil to move, expand or contract will put stress on brickwork. With proper construction methods we can control that movement and extend the life of your patio, walkway or driveway.

Dwayne and crew have given us a beautiful Roman paving stone front and side walkway and parking pad out back. Graceful curves, a perfectionist's attention to technical issues and every minute detail.Read more … On time, on budget. We couldn't be happier.

On time, on budget as promised. Dwayne and his crew worked hard and left nothing behind. The grass looks great, the deck is amazing. We tested it this weekend with a group of family members,Read more … nobody fell through!

We heard about this company and the good work they do from a family member. We subsequently hired them to do a large interlocking brick patio and raised stone planter at the rear of our house. TheRead more … patio was large, with an intricate design. I was extremely impressed with their work, right from protecting our lawn from damage to the excellent work they did on the patio and planter. The crew was very pleasant and worked hard in very hot weather. We have already had many compliments on our new patio and planter and we will be hiring them to do a stone planter in our front yard next year. Very professional and service oriented, which is a nice trait in this day and age!
