Drainage and Soakaway Shingle & Aggregates

Effective drainage is essential for preventing water build-up, protecting structures, and maintaining ground stability. At Smiths Bletchington, we supply high-quality shingle for drainage and soakaway systems for a wide range of construction, landscaping, and groundworks applications.

Our drainage aggregates are available in multiple sizes and supplied in bulk bags or loose tipped loads, providing a practical and cost-effective solution for both trade and domestic projects.

Shingle for Drainage Applications

Shingle is widely used in drainage systems due to its free-draining properties and rounded stone shape, allowing water to flow efficiently through the material.

It is commonly used for:

• Land drainage systems

• Stormwater and surface water drainage

• Pipe bedding and trench drainage

• Ground stabilisation

Using the correct drainage shingle helps prevent blockages, reduce water retention, and improve long-term system performance.

Shingle for Soakaways

Shingle is commonly used in soakaway systems to help manage excess water and support ground permeability. Clean, washed aggregates with minimal fines are important to ensure effective water dispersal.

Our Pea Shingle and Oxford Shingle products are well suited for soakaways, offering consistent grading and reliable performance.

Best Shingle Sizes for Drainage

Choosing the correct shingle size is important to ensure effective water flow and system performance.

• 6mm and 10mm Shingle -suitable for pipe bedding, finer drainage layers, and smaller installations

• 20mm Shingle - a versatile option for general drainage, soakaways, and trench systems

• 40mm Shingle - ideal for larger soakaways and land drainage applications where increased void space is required

• 75-40mm Crushed Limestone - used for heavy-duty drainage and large-scale soakaway systems

Installation Overview

Drainage systems typically follow a straightforward process:

• A trench is excavated and levelled to a suitable discharge point

• A base layer of shingle is placed in the trench

• Drainage pipes are installed and aligned

• Additional shingle is added around and over the pipes

• The trench is backfilled and compacted

In some cases, a geotextile membrane may be used to prevent fine materials from entering the system.
