What Intermountain Slurry Seal does

Intermountain Slurry Seal is a U.S. pavement preservation contractor that delivers preventive asphalt surface treatments to public-sector and, to a lesser extent, private clients. The company applies nine service-line treatments — slurry seal, micro surfacing, chip seal, scrub seal, asphalt rubber (field-blended with recycled tires), cape seal, fog seal, crack seal, and highway striping — using specialized equipment, proprietary asphalt emulsion formulations, and mineral aggregates. Treatments are matched to pavement condition to extend service life, restore skid resistance, seal moisture intrusion, and arrest oxidation, functioning as a lower-cost alternative to full-depth pavement reconstruction. Operations are organized around five regional offices (Salt Lake City UT as headquarters, Lewisville TX, Sacramento CA, Vancouver WA, and Reno NV) covering 21 western and central states.

The company's customer base is anchored by 21 state departments of transportation, hundreds of municipalities, and federal highway agencies accessed via Multiple Award Task Order Contracts, with smaller private-sector and HOA accounts (driveways, parking lots, community streets) rounding out the book. Commercial engagement is project-based: clients request professional pavement evaluations, the firm bids competitively on public works RFPs, and multi-year partnerships are common — testimonial evidence names multi-year engagements with the cities of Midland, San Antonio, Sioux Falls, Amarillo, Baytown, Weatherford, and Kirkland. Free or low-cost pavement evaluations are used as a funnel-into-project-entry-point commercial motion rather than digital marketing.

Intermountain Slurry Seal has been in continuous operation since 1978 (originally founded under Gibbons Companies), was acquired by Granite Construction, Inc. in 1995 as a wholly-owned subsidiary, and currently operates with 51-100 employees. Its competitive position rests on multi-decade technical talent (including a former ISSA president), federal/state specification experience, the multi-state office network, and brand association with Granite Construction's ethical-standards reputation, rather than proprietary software or AI capabilities. The company's industry recognition includes the 2021 ISSA President's Award for Excellence for a Glacier National Park preservation project.

Core offering

Intermountain Slurry Seal is a project-based pavement preservation contractor that applies specialized asphalt surface treatments — including slurry seal, micro surfacing, chip seal, scrub seal, asphalt rubber, cape seal, fog seal, crack seal, and highway striping — to extend the life of asphalt roads, runways, parking lots, and driveways. Services are delivered through company-owned equipment and crews to state DOTs, municipalities, federal agencies, and private clients across 21 western and central U.S. states via five regional offices.

Product overview

Intermountain Slurry Seal is a pavement preservation service company offering a portfolio of asphalt treatment services rather than a unified software platform. The company provides nine distinct treatment products: Slurry Seal, Micro Surfacing, Chip Seal, Scrub Seal, Asphalt Rubber, Highway Striping, Cape Seal, Fog Seal, and Crack Seal. These treatments work both independently and in combination (e.g., Cape Seal combines chip/scrub seal with slurry/micro surfacing) to preserve, protect, and extend the life of asphalt surfaces ranging from driveways to highways, runways, and parking lots. The company operates across 21 states in the western and central United States through five regional offices (Utah, Texas, Nevada, Washington, and California).
