What happens here
Smaller limestone chips, designated as the 'bedding course', are carefully spread over the compacted structural stone. Workers utilize straight metal pipes as screed rails, placing them at the desired grade. A long screed board is then pulled across these pipes, ensuring a consistent depth and a precise pitch for the bedding course. The narrator emphasizes the importance of this slight slope, often imperceptible to the eye, to ensure effective drainage of stormwater away from the house, preventing water pooling and potential foundation issues.
Goal: Establish a level, pitched surface for paver installation with proper drainage.
Tools and materials
- Metal Pipes — Serving as screed rails to guide the screed board and establish the correct grade
- Screed Board — Leveling and smoothing the bedding course
- Shovels — Spreading the limestone chips evenly
- Tape Measure — Measuring depth and spacing of screed rails
- Wheelbarrows — Transporting the limestone chips for the bedding course
- Limestone Chips — The bedding course upon which pavers will be laid
