S3 Precast

S3 Precast, a division of Tanks-A-Lot, was incorporated in 2018 and is proud to offer a full range of precast drainage products including manholes, catch basins and box culverts. All our products are manufactured in our new, 90,000 sq. ft., state-of-the-art facility located in Sherwood Park, AB. This controlled factory environment allows us to produce quality precast products that adhere to the highest standards as dictated by CSA A257.


Manholes, or maintenance holes, provide access to buried infrastructure like storm and sewer lines. Precast concrete structures offer a superior alternative to traditional cast-in-place structures – both in terms of cost and project scheduling.

Our products can be manufactured in a variety of sizes ranging from 1200mm (48”) up to 3000mm (120”). We also have the ability to provide custom openings to accommodate a variety of pipe sizes and types.

Catch Basins

Catch basins are openings to the storm system that typically includes a grate or curb inlet at street level where stormwater enters the unit and a sump captures sediment, debris and associated pollutants.

S3 Precast manufacture catch basins in 600mm and 900mm sizes, complete with all the required tops to suit any steel frame and cover/grate.

Grade Rings

S3 Precast manufactures grade rings in 525mm, 635mm, 710mm and 910mm diameters and 2”, 3”, 4” and 6” thicknesses.

We also make grade rings specific to K7, DK7 and K3 style of catch basin grates.

Box Culverts

Our Universal Form (UF) allows us to manufacture box culverts in a variety of sizes suitable to your project’s unique needs. Check out some of our past box culvert projects here and here.
