Driveway sub-base and drainage
A lasting driveway needs a proper sub-base and drainage. The sub-base distributes load and prevents settlement; drainage prevents water pooling and damage. This guide covers typical construction layers and how we build driveways to resist frost and traffic.
The commercial value of resolving driveway sub-base and drainage early is fewer delays, clearer budgeting, and reduced repeat disruption.

When you might need this
Teams usually investigate driveway sub-base and drainage when early warning signs start affecting reliability, compliance, or project timelines. This is often the point where decision makers move from observation into scoped technical action.
What often triggers action
The symptoms below are the most common triggers we see before diagnosis and repair planning.
- Type 1 or similar sub-base compacted in layers
- Adequate fall for surface water
- Drainage to soakaway or main drain where needed
- Membrane to separate sub-base from subsoil
- Correct depth for vehicle loads
What to expect from the work
We assess the existing ground and any drainage constraints, then specify sub-base depth and drainage. We follow best practice and building control where applicable.
Think you might have driveway sub-base and drainage? A professional inspection will confirm the diagnosis.
How this gets resolved
We excavate, install sub-base and drainage, and prepare the formation for your chosen surface (block, tarmac, resin, etc.). We work with surfacing contractors or deliver a complete package.
Cost and complexity factors
Cost and complexity usually depend on access constraints, total scope, existing condition, and whether related works need to be coordinated in the same programme window.
What the process looks like
We keep delivery structured so scope, sequencing, and sign-off remain clear.
Step 1: Initial assessment
What this step delivers: Root cause and scope are confirmed.
Step 2: Method planning
What this step delivers: Practical repair strategy is agreed.
Step 3: Delivery and verification
What this step delivers: Work is completed and validated.
