The Ultimate Guide to Reinforced Concrete Pipes

Reinforced Concrete Pipes are one of our most popular products. Used primarily for stormwater drainage, Reinforced Concrete Pipes are a key building block in almost any subdivision, roadway or major infrastructure project. Before ordering, it’s important to understand different pipe types, sizes and configurations, to ensure you get the right product for the right job. As one of our most popular products, we are tried and true experts in Reinforced Concrete Pipe. Let us share our knowledge with you in this ultimate guide to Reinforced Concrete Pipes!

What is a Reinforced Concrete Pipe (RCP)?

A Reinforced Concrete Pipe (RCP) is a type of piping made from precast concrete, reinforced with steel rebar for added strength and durability. Available in an array of sizes, ranging from 300mm to 2100mm in diameter, Reinforced Concrete Pipes are used to direct the flow of stormwater runoff (and other liquids) beneath the surface of the earth. Most commonly used as in stormwater or sewer settings, RCP can also be used for large-scale irrigation projects, as culverts or in a range of other pipeline projects.

Why Reinforced Concrete Pipes?

Reinforced Concrete Pipe is the most common and most trusted product for pipelines and water transportation projects. It has been used for centuries in this role, alternatives have sprung up more recently that have caused some debate over which product is best.

High-Density Polyethylene (HDPE) pipes are made from high-grade, strength-tested plastic material and has been used in stormwater settings in recent times. HDPE pipes are considered to be a low-cost alternative to RCP given their price point at purchase. Given the additional costs involved in on-site installation however, including structural integrity tests, engineered backfill, on-site inspections and post-installation laser testing, total cost for HDPE pipes quickly adds up. 

In addition to price, Reinforced Concrete Pipe has been trusted for centuries and has a proven 100-year lifespan. This reduces the need for infrastructure rehabilitation projects, further reducing the ongoing costs of choosing RCP. HDPE pipe is a much more recent product that simply does not have the raw data available to guarantee lifespan claims.

RCP Joint Configurations

There are three main types of joint configurations for reinforced concrete pipe; Flush Joint, Spigot-to-Spigot and Rubber Ring Joint. Typically, Flush Joint pipes are used for heavy-duty stormwater applications, Rubber Ring Joints are used for irrigation, and Spigot-to-Spigot pipes are used at the end of pipelines, to be installed into a precast concrete headwall.

Precast Concrete Classifications

Reinforced Concrete Pipe can be offered in a variety of “classes”. When discussing precast concrete, “class” refers to the finish of the concrete. Class 1 concrete is highest standard with the most rigorous specification and is only recommended for use in very special features of buildings of a monumental nature. When it comes to underground piping, where visual quality is unimportant, Class 1 finish is not required and is generally not offered.

Civilmart offer Reinforced Concrete Pipe in Classes 2, 3 & 4. This allows customers the choice and flexibility of having lower class finishes on purely underground piping, while having higher class finishes on piping that is above-ground or in general view.
