Question 4

Are there height restrictions when building a retaining wall?

Accepted Answer

If you are building a retaining wall to hold up a load, such as a driveway or a swimming pool, or any wall over 3 feet in height, the wall must be engineered by a professional engineer. Always make sure to observe local building codes, and if you have any questions, please consult your Unilock Authorized Contractor.

Question 5

When installing interlocking stones, what do you place between the stones to hold them in place?

Accepted Answer

The best insurance against shifting stones is the proper installation of polymeric joint sands and a stablizing sealer. Additionally, adding edge restraints around the border of your paver installation will ensure pavers don’t shift out of place. Permeable pavers come with special spacer bars at the side of units to provide additional lockup to stabilize the pattern and allow water to flow through.

Question 7

What should I clean my pavers with?

Accepted Answer

All Unilock Dealers carry general cleaning solutions and specialized ones designed for oil and grease, efflorescence, etc. Many customers simply use regular dish soap & water. The main thing is not to use a wire brush (the pieces of wire can become dislodged and promote rust) and to be gentle with the sand.

Question 8

I am planning to power wash my Unilock pavers, do you have any pointers before I do it?

Accepted Answer

There are a few general guidelines when power washing your pavers. Do not use the pressure washer on high power when rinsing, or you risk damaging the surface. Always keep the nozzle at a 30° angle 12″ away from the surface and use the fanned nozzle setting. If some jointing sand washes out, you may need to sweep in some new sand.

Question 9

How do I get rid of moss between my pavers?

Accepted Answer

Moss generally develops in the shaded areas that are slow to dry up after rain. If you want to remove it, it is recommended that you simply pressure wash the surface after applying a solution of 20% dish soap and 80% water to the surface. It is important to remember to not use the pressure washer on high power or too close to the surface when rinsing, or you risk damaging the surface. Always keep the nozzle at a 30° angle, 12’’ away from the surface and use the fanned nozzle setting.

Question 10

Where do weeds come from? How do I prevent them?

Accepted Answer

Weeds do not come from underneath the pavers, they come from seeds that blow in from adjacent properties and fall into the joints and germinate. The best way to prevent weed growth is to put Polymeric Sand into the joints between pavers. Never put plastic underneath the pavers, this will keep the joints wet and only make weeds grow faster.

Question 11

Question 15

Are Unilock wall products safe to use for a fire pit?

Accepted Answer

Our wall products can been used to build fire pits but our stones are not fire rated. If you choose to build a fire pit with our stones you would need to line it with fire brick to withstand the high heat.

Question 16

Are the dimensions advertised in the catalog the best dimensions to use? I do understand that these are nominal dimensions. Do these dimensions include the edge spacing tabs?

Accepted Answer

Our measurements are nominal because there can be small variances in dimensions when forming concrete pavers. Our recommendation is to measure several sample pavers and work from those measurements. One way to confirm measurements is to measure an area of the product laid out at a local Unilock Dealer or Unilock Idea Center. The dimensions do include spacing tabs but we would not use them as a definitive measurement. Areas can also vary due to installation. The size of an area is also dependent on how tightly the pavers are laid.

No, your concrete surfaces should be dry prior to gluing.
