Some of the integrally colored concrete at this Snohomish County residence was left to weather before it was sealed in order to create a visual effect.

Hewlett residence

Location: Snohomish County

Owner/developer: Tony Hewlett

Project team: Promark Decorative Concrete, general and concrete contractor; Smokey Point Concrete, ready-mix supplier

The Hewlett residence is situated in a parklike setting overlooking the Pilchuck River in Snohomish County.

Creating a hardscape on its well-established grounds required a product that could be shaped, textured and enhanced to complement the site.

Eleven-thousand square feet of integrally colored concrete was placed and imprinted with roman slate texture.

The border work is a purely decorative tooling application with no separation values and is monolithic in design. This process allows the use of design elements that were previously thought too difficult to carry out without compromising structural integrity. The cost and time needed to pour separate borders were eliminated, and in the process a more durable, longer-lasting product was created.

The contractor initially sealed only the field portions of the project, leaving the borders and other specific areas exposed to the weather. After a predetermined time the weathered borders and other areas were sealed, producing a warm and flowing picture-framing scheme.

The compass rose, shown in the photo, is an example of the effect that can be achieved with the seal/no-seal process.

The contractor took an aggressive approach to prevent random cracking. Due to proper placement and finishing techniques, sub-grade profiling and advanced crack management, this project currently has zero random cracks.
