The Underground Drainage category at Build4Less features a comprehensive range of products designed for effective and efficient soil and waste management. These products are essential in residential, commercial, and industrial settings for ensuring proper drainage and waste disposal. The category includes various types of pipes, fittings, and accessories, each suited to specific applications.

Pipes and Pipe Fittings

  • Ring Seal Soil Pipes and Fittings: These are used for connecting different sections of the drainage system. Available in various angles (like 92.5 degrees), they ensure a tight and secure fit. Their primary use is in creating junctions or turns in the drainage system.
  • Solvent Weld Pipes and Fittings: Designed for a permanent joint, these pipes and fittings are welded together using a solvent. They are ideal for systems where a strong, leak-proof connection is required.
  • Single Socket Underground Pipes: These pipes, often used in lengths of 3m or 4m, are essential for the main drainage lines. They typically feature a single socket end for easy connection.

 

Specialised Fittings

  • Strap Bosses and Boss Adaptors: These components are used to create additional connections to existing pipelines. They come in various sizes and are essential for branching off a main line.
  • Bends and Elbows: Available in different angles (like 87° and 92.5°), these fittings are used to change the direction of the drainage system.
  • Couplings and Connectors: These are used to join sections of pipe together. They come in different types, including straight, double socket, and adjustable variants.

 

Access and Inspection Components

  • Access Pipes and Covers: These provide access points for maintenance and inspection of the underground drainage system. They come with single sockets and in various designs like cast iron effect.
  • Inspection Chambers and Risers: Essential for providing access for inspection and maintenance, these chambers come in various depths with risers to adjust to the required level.

 

Additional Accessories

  • Gully Sets: These include components like silt buckets and iron gating, typically used in yard drainage.
  • Sealing Rings and Clips: These small but vital components ensure a secure and leak-proof drainage system.
  • Soil Pipe Clips and Plugs: Used for securing pipes and closing off unused ends or branches in the system.

 

Material and Colour Variations

  • PVC-U and Cast Iron Effect: Most of these products are available in durable materials like PVC-U, with some also available in a cast iron effect for aesthetic preferences.

 

Usage and Application

The choice of product depends on the specific requirements of your project:

  • For residential projects, standard ring seal soil pipes and fittings are often sufficient.
  • In commercial settings or areas requiring robust connections, solvent weld systems are advisable.
  • For maintenance and inspection purposes, access pipes, covers, and inspection chambers are essential.

 

Choosing the Right Product

Consider the following when selecting products:

  • Compatibility: Ensure the chosen fittings are compatible with existing pipes.
  • Angle and Size: Select the correct angle for bends and the appropriate size for pipes and fittings.
  • Material: Choose materials based on durability needs and environmental conditions.

     

Each product in this category is designed to meet specific needs in the underground drainage system, ensuring efficiency and reliability in soil and waste management.
