Alder Bau AG (Herisau)

Today, the construction company is still a 100% family business. In 1992, Markus Alder replaced the second generation in the management. According to Markus Alder, the company stands on a healthy foundation.
He cites the motivated employees and the versatile machinery as the company's main plus points.

The company's loyal customer base includes cantons, various municipalities, all utilities (supply and disposal), companies, land cooperatives and private individuals. "We always strive to find customer-oriented solutions that offer the best possible cost-benefit ratio. We attach great importance to early and expert advice."

As a result, the company is often involved in the planning phase, and the managing director says, "There has never been a road construction problem that we couldn't have solved." The company carries out large and small orders.

The range of services related to road construction is diverse. Among the specialties are: bituminous pavements, whether black or even colored, natural and concrete stone paving, embankment construction, environmental works, sewerage systems, works pipelines, as well as drainage. In any case, says the managing director, Alder Bau AG is on the right track - and has been for almost 90 years.
