ROAD CONSTRUCTION & INFRASTRUCTURE
Drainage Construction
Road drainage construction helps move rainwater away from the pavement, access routes and adjoining site areas.
Overview
Standing water can affect road safety, surface condition and the underlying layers. A drainage scheme considers where water arrives, how it flows and where it can be discharged. Jay Ambe offers road-edge and site drainage work alongside new road construction, repairs and infrastructure projects. Levels, outlets and connections are coordinated with the finished road surface.
Explore our Road Construction & Bitumen Work Specification for material and layer details, and see Our Equipment for the machinery behind the work.
Key capabilities
- Surface-water routes considered with road levels

Frequently asked questions
Often yes, but the available levels and a suitable discharge point need to be checked.
Surface falls, blocked outlets or surrounding site levels can all affect drainage.
Yes. These elements should be set out together so water is directed to the intended outlet.
