No, it is not necessary to seal pavers. That being said, sealing can help prevent color fading and does provide some measure of stain protection for your pavers. If you do decide to seal your pavers, the pavers must be clean and dry before sealing and we recommend waiting at least 30 days after initial installation before sealing your pavers. Once sealed, you will need to re-seal approximately every two to three years.

For mortarless brick paving, a flexible base consisting of compacted crushed stone, gravel or coarse sand can be used. A semi-rigid base consisting of asphalt is also suitable for mortarless brick paving, as is a rigid base comprising a reinforced or unreinforced concrete slab on grade.

For mortared brick paving, a rigid base must be used.

Paver installation should always start with the correct base material for the job. At Allied Paver Systems we recommend crushed rock with approximately 1½” of concrete or gunite sand.

Additionally, the installation of proper edge restraints is essential to preventing the spreading of pavers. Failure to follow these installation guidelines can cause pavers to spread over time.

Yes, brick paving can be installed over existing concrete or asphalt, provided it is in reasonably good shape.

To ensure an adequate foundation for the brick, the existing concrete slab or asphalt should be inspected and any cracks, chips, holes, ruts or spalls should be repaired in order to achieve a flat surface prior to installing brick pavers.

Pavers are inherently a more environmentally friendly option than concrete, as well as being much easier to work with when it comes to repairs. To carry out an underground repair, simply remove the pavers in the affected area, complete the repair and re-lay the pavers. The same repair would be a much larger and more difficult job with concrete. Additionally, pavers are a flexible pavement and therefore are not prone to surface cracks that often occur with the use of regular concrete.

As an added bonus, interlocking pavers are aesthetically pleasing, which can add significant value to your property as well as enhancing curb appeal.

The maximum height, including embedded first course, for a gravity (non-reinforced) retaining wall using the following products is:

Vertica Pro: 6 feet 3 inches, including 6” embedment (5 feet 9” above grade)* (10 courses)

Vertica: 3 feet 1 ½ inches, including 6” embedment (2 feet 7.5” above grade)* (5 courses)

Diamond Pro: 3 feet 4 inches, including 6” embedment (34” above grade)* (5 courses)

Highland: 4 feet, including 6” embedment (3 ½ feet above grade)* (7 courses)

Bayfield: 3 feet, including 6” embedment (2 ½ feet above grade)* (6 courses)

Diamond: 4 feet, including 6” embedment (3 ½ feet above grade)* (7 courses)

There are a number of products available that are specifically designed for cleaning pavers. You can use a pressure cleaner on pavers, but we do not recommend using more than 1,000 PSI of pressure as this risks damaging the pavers’ surface.

For serious stains such as tire marks, we would recommend hiring a professional to clean the pavers.

Yes, however, a terraced wall creates a surcharge load on the lower wall. Therefore, the distance between the walls should be greater than two times the height of the first (lower) wall.

EXAMPLE: If the first (lower) wall is 3 feet high, then the second wall must start at least 6 feet behind it. There are some exceptions to this rule, but a higher degree of engineering is required because the walls are no longer considered independent.

The easiest way to control ants, grass, mildew and weeds is to have your pavers professionally sealed and utilize a Belgard Polymeric Sand or Techniseal Joint Sand Stabilizer.

The use of weed killer and insecticide will also help control weeds and insects without staining your pavers.

An integral rear lip or raised locator (Vertica) is manufactured into the blocks. The lip and locator automatically guides each new course; thus ensuring proper alignment and precise setback without the use of pins or mortar.

“Brick” is a common term that generally applies to clay products. Face bricks are typically cored (which means they have holes in them) and are commonly used for vertical applications such as walls.

Pavers can be made out of either clay or concrete, are available in a wide variety of different sizes and thicknesses and are used for horizontal applications such as driveways, patios, poll decks and walkways.

Our deliveries are made via semi-trucks that are equipped with a special forklift called a moffet on the back. This forklift detaches from the truck and can place materials near the work area, provided there is an opening at least 10’ wide and 10’ tall for the forklift to get through. These are very heavy machines and we ask customers to take this into consideration when deciding where materials should be placed so as to avoid damaging things such as sprinkler heads.

The minimum radius is measured to the face of the blocks:

Vertica Pro (Bev & Str) 7 feet outside, 7 feet inside

Vertica Beveled: 4 feet outside, 7 feet inside

Vertica Straight: 7 feet outside, 7 feet inside

Diamond Pro Bev: 2 feet outside, 4 feet inside

Diamond Pro Str: 4 feet outside, 8 feet inside

Diamond Beveled: 2 feet outside, 4 feet inside

Diamond Straight: 4 feet outside, 8 feet inside

Highland: 4 feet outside, 8 feet inside

Bayfield: 4 feet outside, 8 feet inside

Aspen: 2 feet outside, 4 feet inside
