MOT Type 1 Sub Base Loose Load Tonne

Product Overview

MOT type 1 sub base supplied in a loose load format. This material is a crushed granular aggregate composed of limestone, granite, or recycled concrete, graded to comply with the Department of Transport Specification for Highway Works (Clause 803). 

It provides a stable and well-compacted foundation layer for driveways, access roads, paths, and construction platforms. The material forms a dense load-bearing layer when compacted, supporting overlying tarmac, concrete, or paving. 

Supplied as a bulk loose load, it allows direct tipping for large-scale groundwork or surfacing projects where efficiency and volume delivery are essential. 

Features & Benefits

• High Load Capacity: Forms a durable and stable base layer capable of supporting heavy vehicular or structural loads.
• Uniform Compaction: Graded composition ensures excellent interlock and compaction for long-term structural integrity.
• Specification Compliant: Manufactured and graded to Clause 803 of the Specification for Highway Works.
• Bulk loose format: Delivered without packaging to allow for direct tipping and immediate use on large-scale groundwork areas.
• Tipping vehicle delivery: Supplied on a specialised lorry designed to offload the material by tipping directly onto the ground.

Applications

• Driveway and Road Foundations: Provides a compacted sub-base suitable for tarmac, block paving, or concrete surfacing.
• Car Parks and Access Routes: Forms a stable structural layer for heavy-use vehicular areas.
• Construction Platforms: Offers a level and load-bearing base for plant and machinery.
• Hard Landscaping Works: Used beneath patios, pathways, and garden structures.
• Large-Scale Groundworks: Suited to developments where bulk quantities are required for uniform surface preparation.

Installation Guidance

• Ground Preparation: Excavate and level the subgrade before laying the material.
• Layer Thickness: Spread in uniform layers, typically 100–150 mm thick, depending on design requirements.
• Compaction: Compact each layer thoroughly using a roller or vibrating plate until maximum density is achieved.
• Moisture Control: Lightly dampen material if required to aid compaction and reduce dust.
• Final Surface Check: Ensure even surface levels and firm compaction before applying surfacing materials.

Compliance & Performance

• Specification Standard: Conforms to the Department of Transport Specification for Highway Works, Clause 803.
• Material Composition: Blend of crushed rock or concrete aggregate typically ranging from 40mm down to dust.
• Load-Bearing Performance: Designed for use beneath highways, driveways, and heavy-duty paved surfaces.
• Delivery method: Supplied loose via a tipping lorry and discharged directly onto a clear, hard-standing area.
• Non-returnable status: This product cannot be returned or refunded once it has been offloaded from the delivery vehicle.
• Important note: Ensure the tipping area is clear of overhead cables and has sufficient space for a large HGV to manoeuvre safely.
