What are hardscapes and hardscaping?

For us, hardscape design and hardscaping is the expert integration of a variety of materials such as stone, pavers, and wall block into something aesthetically pleasing. Patios, paver driveways, walkways and walls are designed and installed not only for function, but fashion as well.

New Builds:

It starts with the design process. Please click here to go to our Project Management page.

Once designed, we install for the long term. We have ICPI (Interlocking Concrete Pavement Institute) certified paver installers, and NCMA (National Concrete Masonry Association) certified Segmental Retaining wall installers. Their standards insure we do it right the first time. The real work is in what you don’t see – the proper excavation, sub base, base, and drainage.

Because of our quality and attention to detail, we are Authorized Installer Contractors for several Paver and Wall manufacturing companies, including Techo-Bloc, Unilock, and Belgard.

Here are some frequently asked questions:

Why not seal right away?

Polymeric sand needs to cure and pavers need to age to limit efflorescence problems.

What is the expected life of sand joints in new paving surfaces?

Depending on site conditions, 3-5 years can be expected.

How often will I need to reseal?

Depending on site conditions, every 3-5 years.

What should I expect from my old pavers when newly cleaned?

Paver color will be brightened and some aggregate in pavers may be exposed when debris is removed.

Will sealing prevent moss and mildew?

Sealing, along with routine annual maintenance, will slow down and limit moss and mildew build up, but not eliminate moss or mildew.

What is the best time to clean and seal?

Cleaning and sealing is best done in warmer temperatures to allow for adequate drying, summer months of June-September are best.

Will sealing make my pavers slippery?

There are two main types of sealers, film forming and penetrating, and each have their specific applications. As a general rule, where slip hazards are a concern, penetrating sealers are applied.

Joint and Sealing Options:

New Paver Option

(For pavers installed within past 3-4 years)

  • Starts with installation of Techniseal RG+ or HP2 polymeric sand at paver installation followed by at least 15 days curing period for sand joint and 90 day paver aging period.

  • If needed stains will be removed with appropriate product.
  • Pavers will be primed with Paver Primer of Efflorescence Cleaner.
  • Application of appropriate Techniseal Protector which PA Landscape Group Inc. will work with customer to select and sample.

Older Paver Installations

(For pavers installed over fiver years ago)

  • Polymeric sand is removed from paver joint to depth of approximately 1.5″ with pressure washer. This process also cleans dirt and debris from the surface of pavers, brightening them up.
  • After appropriate drying time (24 to 48 hours) Techniseal RG+ or HP2 polymeric sand will be installed and allowed to cure for 15 days.
  • Pavers will be primed with Paver Primer or Efflorescence Cleaner.
  • Application of appropriate Techniseal Protector which PA Landscape Group Inc. will work with customer to select and sample.
  • PA Landscape does not warranty new polymeric sand joint.

Annual Paver Maintenance

(1-2 times yearly)

  • Apply Techniseal Hardscape Cleaner to pavers.
  • Scrub solution onto pavers with stiff bristle broom.
  • Rinse with light pressure from hose.


The combination of sealing and routine cleaning of pavers and sand joints will help to prevent discoloration from moss, mildew and other organic stains protecting your paver investment.
