Experience.
When it comes to civil concrete projects, reliability, consistency and speed matter. At Graham’s Precast Concrete Products, we manufacture and supply durable, precast components built to meet the demands of construction and infrastructure works across QLD and NSW.
Whether you’re managing drainage, roadworks or site access, our concrete products help reduce delays, simplify installation and support long-term performance on site. Our civil range includes precast headwalls—available in single-cell, double-cell and sloping configurations—designed to suit both concrete and plastic pipes from 300mm to 675mm.
Built off-site to strict standards, each unit arrives ready to install with no need for formwork, weather-dependent curing or excess labour. It’s a smarter way to build, backed by over 40 years of industry knowledge.

What We Do
Alongside our civil products, we supply a full range of precast concrete solutions designed to support rural properties, plumbing systems, livestock infrastructure and more.
Concrete Septic Tanks
Designed for longevity and built to national standards, these tanks are a smart choice for wastewater management. They’re watertight, durable, and ready for backfill from the day they're delivered.
Septic Tank Installation
Our installation-friendly tanks reduce time on site. With crane-compatible delivery and support available, it’s easy to get your system in the ground quickly, without sacrificing compliance or reliability.
Concrete Reed Beds
Used after septic tanks, reed beds naturally filter wastewater with minimal maintenance. They're ideal for off-grid properties or eco-conscious projects looking for a sustainable finishing stage in treatment systems.
Concrete Cattle Grids
From rural driveways to council roads, our concrete grids keep stock contained and traffic flowing. Built without steel, they resist rust and stand up to daily wear and weather extremes.
Concrete Feed Troughs
Feeding livestock is simpler with our stable, easy-to-use troughs. They’re built to withstand kicks, pressure, and exposure, making them a great fit for busy farms and grazing setups.
Concrete Water Troughs
Reliable hydration for animals starts here. Our precast water troughs are strong, weather-tolerant, and suitable for a wide range of livestock, helping you reduce refills and manage water efficiently.
