Description

🏗️ Screened Pit Run for Strong Foundation Bases, Driveways & Site Preparation

 

Thrifty Alberta’s Screened Pit Run is a durable, cost-effective aggregate engineered for foundational strength and compaction. Sourced from natural deposits and processed to remove oversized debris, this material features a reliable blend of sand, gravel, and small stones ideal for roadbeds, staging areas, rural driveways, and heavy equipment pads.

Whether you’re building infrastructure in Calgary, setting up driveways in Red Deer, or prepping sites around Edmonton, Screened Pit Run is trusted for consistent performance and wide availability across Alberta.

🪨 What Is Screened Pit Run?

 

Screened Pit Run is raw pit material that has undergone mechanical screening to ensure uniformity in particle size and eliminate large rocks, roots, and foreign debris. The result is a clean, well-graded aggregate perfect for compaction and foundational support.

It bridges the gap between loose Pit Run and processed gravel by offering a naturally strong, yet more predictable base layer. It can be placed beneath road crush, asphalt, or concrete to provide volume and strength while enhancing drainage and surface stability.

🚧 Primary Applications

 

This material is commonly used in:

• Rural driveways – Strong enough to support regular traffic without rapid breakdown

• Construction pads – Preps areas for equipment staging and long-term use

• Road construction – Acts as the sub-base layer beneath crushed gravel and asphalt

• Foundation build-ups – Supports commercial and residential footings and grade adjustments

• Temporary roads or detours – Durable enough for utility and construction traffic

✅ Advantages of Screened Pit Run

 

• Cost-effective – Provides mass coverage at a lower cost than crushed stone

• Uniform grading – Screens out large rocks for better compaction

• Excellent drainage – Prevents pooling under roads and pads

• High load capacity – Withstands heavy equipment and long-term compression

• Bulk availability – Stocked year-round and deliverable across Alberta

🛠️ Installation Tips

 

• Always compact in 4–6 inch lifts to maximize strength

• Water lightly during placement to activate fines for better binding

• Layer with finer aggregate or Road Crush for top surfaces

• Use geotextile fabric underneath for added separation and stability in soft soils

 

Combine it with Limestone Base Coarse for engineered structural layering or follow it with Road Crush to create a compactable final grade.
