Precast Concrete Grease Interceptors

Mixed reports and different types of materials available for interceptors can result in confusion. Which type of grease interceptor or oil separator should you include in your design or should you consider purchasing? Precast concrete interceptors have the advantages you are looking for, regardless of the false claims made by other material manufacturers. Don't believe the myth. Save yourself time and money. Our precast concrete interceptors comply with the plumbing code, and we have third party certification.

With a specific gravity of 2.40, concrete structures resist buoyancy in water table applications, unlike other materials used for detention tanks. In comparison, fiberglass has a specific gravity of 1.86 and high density polyethylene (HDPE) has a specific gravity of only .097. Setting precast concrete grease interceptors is easier than those materials because they do not require special rigging to avoid structural damage. Fiberglass or HDPE can suffer structural damage during compaction, and is more susceptible to vibratory damage while surrounding soil is backfilled. Consequently, backfilling operations can usually proceed much faster around precast structures. You don't have to pour a slab over the top of our interceptors and separators - they are built to meet AASHTO H-20 loading on their own. Why pay extra??? We stock most size interceptors, so can service your job in two weeks or less. Sometimes we can deliver the day after you call. Why wait longer???

Why Precast Concrete?

  • Superior Strength and Durability
  • Modern Concrete Mix Designs Resist Corrosion
  • Concrete Mass Resists Bouyancy Unlike Plastic or Fiberglass Materials
  • Quick Availability
  • Environmentally Friendly (concrete is one of the most Green construction materials you can buy).
  • Maintenance Ease and Accountability
  • High Degree of Quality Control
  • Support of Local Manufacturers
  • Most Economical Choice

Our precast concrete grease interceptors comply with applicable sections of the 2018 Michigan and International Plumbing Code.

Advance Concrete Products Co. routinely sends highly trained, experienced drivers that can set your grease interceptor or oil and water separator in your prepared excavation with our trailer mounted crane. We don't merely put your interceptor on a flatbed common carrier and then send you a bill. We follow through from design to installation. You get personal service.

Concrete Grease Interceptors - Tried, Trusted, True

Some suppliers of fiberglass and HDPE grease interceptor products, which can be significantly more expensive than concrete, have asserted that precast concrete grease interceptors fail to meet code and have called into question the quality, reliability, durability and longevity of concrete grease interceptors. These claims – and others made by these fiberglass suppliers – are quite simply false and misleading. The National Precast Concrete Association combats every one of these claims with the facts.
