ACO is an acronym of Ahlmann Company.  The Ahlmann family started ACO and the 3rd generation still runs it.

 Approximately 4000 employees worldwide.

In 1946 Josef-Severin Ahlmann (1924-2006) set up his new company, ACO, on the site of the Carlshutte Foundry in Budelsdorf, near Rendsburg, Northern Germany.  Initial products were concrete with polymer contrete channels being added in the late 1960s.

In 1972 ACO set up a company in Switzerland, followed by France in 1976 and the United States of America in 1978.  Since then the ACO Group has expanded globally and today has companies worldwide.

It is understood that standing water in and around facilities can cause severe structural damage.  Potential problems include cracked foundations due to static water pressure buildup on the walls, degradation of adjoining building materials and freeze-thaw issues.  Similarly, ponding (i.e. water collection) and hydroplaning on roads, highways and bridges are possible safety hazards that can be avoided.

Effectively handling and transporting away rainfall during and after storms is a prime component in facility and road construction planning.

Surface drainage can be accomplished using three different systems - catch basins, open swales or grated trench drains.  Cost comparisons have shown modular trench drains to have lower total installed costs when labor, excavation, pipework, grading, etc. are taken into account.

Polymer concrete is a durable material which is resistant to road salts and common chemicals.  It is made from polyester resin reinforced with mineral aggregates and fillers.
