What is Glass Fiber-Reinforced Concrete (GFRC)?

GFRC is a composite material consisting of Portland cement, fine aggregate, water, alkali-resistant glass fibers and additives which, when mixed in exact proportions and manufactured under controlled conditions with special equipment, achieves construction-grade physical properties that allow it to be used for numerous applications, especially those where weight is a significant factor in the design.

GFRC was first introduced to the world's building industry more than 25 years ago starting in the United Kingdom and Europe. It's popularity among architects, engineers and construction firms soon spread to the USA, Middle East, and South East Asia.

In recent years, contractors in the landscape and pool & spa industries have discovered the benefits of learning how to use GFRC boulders and rock cliff panels for custom waterfalls and other water features at residential and commercial projects which--when designed, installed and colored properly--appear as if they were carved by erosion a thousand years ago.

The material is frequently specified by architects and engineers in historical landmark restoration projects and used to replicate deteriorated stone, cast stone, and even architectural terra cotta.

GFRC Offers Excellent Strength-To-Weight Ratio

One of the biggest advantages of GFRC is it's relative strength to weight ratio, which is far greater than that of ordinary hard rock precast concrete.

Our exclusive GFRC mixture exceeds standard industry formulations that have been tested to achieve a tensile strength of up to 9000psi, compressive strength up to 1300psi, flexural strength up to 5000psi, and a permeability of 1200 coulombs in addition to having earned an "excellent" rating in freeze thaw resistance after withstanding over 300 rapid freeze thaw cycles considered to be the equivalent of 100 or more North East winters.

Landmark's One Year Warranty

Our GFRC boulders and rock cliff panels are manufactured to exceed industry standards and have a one year warranty against proven defects in material or workmanship from the original date of purchase (or installation if used for one of our design-build projects).
