Design and materials

The Infinity model is cast in UHPC to achieve thin profiles, tight edges, and consistent durability without adding unnecessary bulk. The matte artisan finish is applied by hand and can be ordered in any Kujira color to complement modern backyard decor or a minimalist patio warmth scheme. Because the unit is UHPC-based, it supports a smooth, low-porosity surface that performs well in outdoor fireplace applications while maintaining the look of a custom artisan exterior.


Burner, fuel, and operation

The included HPC Match Light Tornado burner is specified for a bold linear flame, acting as a large gas burner suited for both natural gas and liquid propane installations. The rectangular gas feature is supplied ready for connection by a qualified technician; tumbled Mexican lava rock is included to visually fill the burner trough and moderate heat radiation for patio comfort. Use as a propane patio heater alternative where local codes and supply permit.


Installation and placement

At 120 inches long and weighing 585 lbs, the Infinity requires a stable, level foundation and clearances that meet local code. Its long rectangular hearth form is intended to serve as a commercial lounge focal or a striking centerpiece for residential entertaining areas. Position the unit on a noncombustible surface and consult local professionals for gas hookups and siting to preserve warranty eligibility.


Care and warranty

Routine care consists of removing debris from the lava rock and rinsing the concrete surface with mild soap and water when needed; avoid harsh acids or abrasive cleaners to protect the matte artisan finish. The unit ships with a 1-Year Limited Warranty covering manufacturing defects; please register with Kujira Concrete for warranty details.

The Nature of Concrete


KUJIRA products are handcrafted one at a time using a custom concrete formulation designed to endure. Because concrete is a living material, each piece carries its own distinct character—soft tonal shifts, organic texture, and natural variation. This individuality is intentional, embracing the material’s honesty and making every KUJIRA piece truly one of a kind.

Holes & Pock Marks

Naturally occurring air pockets formed during casting.

Color Variation

Subtle shifts in tone are inherent to concrete and vary from piece to piece.

Texture & Flow Lines

Organic movement created as the material settles and cures.

Connection Seam

A visible line where molds meet — intentional, honest, and structural.
