At Mack Industries, we manufacture high-quality, precast concrete manholes that are vital components of today’s modern sewer systems. A concrete manhole from us will be fireproof, highly durable and watertight across every application at any job site. With its ultra-high compression strength, concrete is the ideal material for new and replacement manholes. Here’s a quick look at why a precast concrete manhole is superior to brick, cast-in-place and other non-concrete products.
Highly Durable, Long-Lasting
Our precast concrete manholes are made in a controlled environment that produces consistent quality and uniformity. Unlike pour-on-site jobs, we can control the temperature, materials, curing conditions and workmanship to produce a highly durable, long-lasting product.
A Cleaner, Better Worksite
Since we precast our manholes at our facility and deliver them to the job site, there is significantly less noise, dust, truck traffic and mess compared to projects that require concrete to be poured on-site. In addition, precast concrete manholes are standardized and modular so they are easier to install. This helps save time and energy, lower noise levels and minimize emissions released by gas and diesel powered equipment.
Mack precast concrete manholes help lower your costs, simplify your projects and make your timelines more predictable. Regardless of the weather, you can install a precast concrete manhole on the day it’s delivered. Additional key benefits include:
