01248 353 595 Yes, pipe bedding should be lightly compacted to remove voids and provide consistent support, but care must be taken not to over-compact, as this could damage the pipe. Proper compaction ensures alignment, stability and long-term performance.

How are Hogan aggregates quality assured?
All Hogan aggregates are sourced from 3 carefully managed sustainable quarries and processed through modern crushing and screening equipment to maintain consistent grading and performance.
Our team tracks quality and gradings continuously, not just at start-up – an ongoing loop of sampling, checking and nudging.
Every load is subject to rigorous quality control, giving contractors confidence in strength, durability and compliance with relevant standards.
What are the different sizes of pipe bedding?
10mm pipe bedding gravel
Fine, close-knit support: 10mm is ideal where you need tight contact around smaller diameter pipes and fittings, giving excellent side support and reducing the risk of voids under the barrel.
Smooth compaction: the smaller stone size knits together quickly, so crews can shape and compact around the pipe without fighting oversized pieces or bridging.
Versatile on tight jobs: perfect for service trenches, shallow runs and locations where you want a neat finish and easy level control around crowded utilities.
14mm pipe bedding gravel
Balanced grading: 14mm strikes a balance between the close support of 10mm and the drainage capacity of 20mm, giving a stable, well-interlocked bed.
Strong support for heavier lines: the slightly larger stone size gives a more robust skeleton in the embedment, ideal for mid–to large-bore pipes needing extra side bearing.
Reliable for deeper covers: where cover depths increase, a quality 14mm aggregate helps distribute load through the bedding, reducing differential settlement around the pipe.
20mm pipe bedding gravel
High drainage capacity: 20mm gravel is widely used for combined bedding and drainage, allowing water to move freely away from the pipe zone.
Robust under load: the coarser particle size creates a strong, interlocked matrix, ideal where pipes sit under trafficked areas or require higher bearing capacity.
Multi-purpose on site: 20mm is equally at home as pipe surround, backfill and general drainage layer, helping you standardise materials across the job.
What is the best gravel for pipe bedding?
Pipe bedding gravel is a free-draining, evenly graded aggregate — typically 10mm & 14mm gravel or crushed stone. It is placed beneath and around pipes to create a uniform, easily compacted base that cushions and stabilises the pipe, prevents voids and misalignment, and allows water to flow away safely.
