Okay – Just when you thought you were going to pour another grey concrete patio and walkway or pool deck for a client, they inform you that they want their concrete to glow with glow stone.

At this point, some of you will get a little tense about placing something into your client’s concrete that you’ve never played with before… We understand your hesitation but rest assured – IF you have ever done any decorative concrete work in the past where you’ve seeded/broadcasted seashells or colored glass onto the surface of a setting slab and then exposed it – this will be a walk in the park!


Who is Ambient Glow Technology and Why AGT™?

We are the world leader in high performance glow aggregates for concrete. Since developing the current industry-standard – AGT™ Commercial-Grade glow stone in 2008, Ambient Glow Technology remains on the cutting edge of glow stone manufacturing technology.

In order to ensure that clients have access to the most state-of-the-art glow aggregates in the world, we created our R&D division – AGT™ Glow Labs. Since 2008, this department has developed a number of new photoluminescent aggregates and coatings. Most notably in mid 2015, we unveiled the world’s first DIN67510 Part 1 compliant super-luminosity glow aggregate AGT ULTRA™ – which boasts the longest and brightest afterglow in the industry.¨


Our reputation is as important to us as yours is to you…!

If it was tricky to apply AGT™ glow stone or required special skills and the moon had to be aligned with a certain star constellation… We probably wouldn’t be enjoying such international success. Over the past 7+ years, thousands of concrete contractors in over 38 countries and on all 5 continents have worked with and mastered the basic process of powering concrete with AGT™ glow stone.

Give us a call TOLL-FREE at 1 877 248 8641 and our dedicated AGT™ Applications Team will be more than happy to share their 10+ years of real, hands-on experience applying AGT™ glow stone in concrete and other substrates.

Non-Radioactive AGT™ is non-toxic and safe for use in all types of environments.
Outstanding Luminosity Exposure to sunlight for 10 minutes produces an afterglow of over 10+ hrs. Exposure to artificial light such as Halogen, Florescent etc. for approx. 20-30 minutes produces an afterglow of over 12+ hrs.
Performance The luminosity of the AGT™ line of ULTRA and COMMERCIAL-GRADE Glow Stone is dependent on grade and glow color. For example, Emerald Yellow ULTRA grade 12mm glow stone exhibit an initial burst intensity of 12 510 3612 mcd/m2 @ 1min. and then begins to degrade over time once removed from a light source. For more information, please refer to AGT TECH DATA SHEET #003 & #004.
Stability of Physical And Chemical Properties AGT™ works perfectly between +500ºC and -20º C. It is also resistant to high and/or extended exposure to ultraviolet radiation and does not discolor under 300-watt high mercury lamp for 1000 hours at 35ºC – 40ºC, 80% humidity. AGT™ is unaffected by most chemicals and performs exceptionally even in the worst outdoor conditions. AGT Glow Stones are not affected by extreme climates such as high heat, sub zero cold or wet environments. AGT Glow Stone DO NOT expand or contract in concrete or any other substrate.
Fine Particles
The AGT™ line of high performance glow aggregates range in particle size from 350 mesh sand to 12mm Glow Stone.
