The Ideal Pipe for Alkali Soils and Erosive Environments

Contech’s CORLIX aluminum pipe provides a predictable service life of more than 75 years. It is the ideal pipe for municipal storm sewers, underground storm water detention systems or any standard drainage project that must withstand alkali soils and erosive environments. In addition to its long design life, CORLIX is an economical alternative to reinforced concrete pipe.

CORLIX weighs only 1/35 as much as reinforced concrete. Lighter weight means easier installation. Trench width (and depth) are reduced due to the smaller outside diameter, resulting in time and cost savings for both excavation and backfill.

Single lengths up to 40 feet ensure more accurate pipe alignment at time of placement and through the life of the system. Longer lengths save installation time with fewer joints.

Easy, fast pipe cutting on the job is simple with standard tools. Since there are no riveted joints, CORLIX can be cut at any point. Cuts and welds need no protective treatment. Wide availability of fittings saves installation time in the field. Fabricated elbows, manholes and catch basins minimize hydraulic losses at junction structures.

CMP for Culverts, Canals and Ditch Enclosures

Our corrugated steel pipe is the most durable, economic, and widely chosen material for most culverts.

ULTRA FLO for Storm Sewers

No other type of drainage structure offers the range of structural strength that’s available with ULTRA FLO - which continues to perform where rigid pipe fails. We offer coatings and linings that will provide a minimum of 75-year service life for most soil/water conditions. ULTRA FLO provides a Manning’s “n” = 0.012, equal to concrete pipe and other smooth wall drainage products. There are custom fittings and coatings to meet your project needs.

CMP Stormwater Detention Systems

CMP stormwater detention systems store stormwater runoff exceeding a site’s allowable discharge rate and release it slowly over time. Installed below grade, stormwater detention systems maximize land usage and help meet water quantity requirements.

CMP and PVC Pipe for Pipe Reline

Lining inadequate or failing structures with corrugated metal material or plastic pipe uses little of the available area, thereby preserving the maximum amount of the original opening. Due to the hydraulic efficiency of Contech products, often a smaller structure provides the same hydraulic capacity as the original because of the low Manning “n” factors of A-2000 and A2 Liner PVC pipes and HEL-COR and ULTRA FLO CMP pipes. Existing pipes and arches are generally lined with structures of the same shape, though slightly smaller in size. Rectangular openings can be lined with round, elliptical or pipe arch structures. Corrugated metal structures can fit almost any existing shape.

CMP and PVC Pipe for Rehabilitating Storm, Sanitary Sewers and Small Culverts

Reline drainage structures with hydraulically efficient corrugated steel, aluminum or PVC pipe. ULTRA FLO and HEL-COR are CMP Pipes available in standard diameters through 120” and 144" respectively. Special diameters are also available in both products. The PVC pipe systems, A-2000 and A2 Liner Pipe—used for both drainage structures and sanitary sewers—are available through 36” diameter.
