We deliver clear, compliant, and site-specific strategies to manage surface water and flood risk
Our services include:
Flood Risk Assessment
We provide Flood Risk Assessments which assess flood risk from all relevant sources —fluvial or tidal, surface water, groundwater, and reservoir—using the latest data and national policy guidance.
Drainage Schemes
We specialise in management of surface water (SuDS) and flood risk, providing drainage schemes for residential new builds and extensions over 25 square metres to meet planning requirements.
We deliver innovative solutions that meet the unique needs of our clients as well as prioritising sustainability.
We assist in making diversion and new connection applications to water companies.
Independent Technical Review & Assurance
Third-party review of civil engineering designs and construction activities for major infrastructure and public-sector projects.
We provide independent technical review and assurance for complex infrastructure projects, supporting clients in managing risk, governance, and long-term asset performance.
Logistics & Major Infrastructure
HydroGround Civils Ltd provides civil engineering and independent technical review services for logistics and industrial infrastructure, including large hardstanding areas, intermodal environments, and flood-sensitive sites. Our work places particular emphasis on drainage performance, resilience, and constructability at both design and construction stages.
Feasibility Study & Advice
We help you to make informed, confident decisions early in the design and planning process to avoid delays and higher costs down the line.
We work closely with architects, planners, and developers to ensure that drainage and flood risk strategies are considered early and aligned with sustainable, practical outcomes.
BRE365 Soakage Test
We carry out soakage testing across the South East of the UK.
A BRE365 soakage test may be required to be carried out as part of your planning application. This test is a crucial aspect of design for any project that intends to use infiltration to manage surface water on site.
We will carry out the test at a time that suits you and provide you with a detailed report.
Other Services
We use AutoDesk Civil 3D to deliver a comprehensive range of bespoke civil engineering design services for our clients. Our expertise includes:
Cut and Fill – Accurate earthworks calculations, ensuring efficient material balance and optimized construction planning.
Swept Path Analysis – Professional vehicle movement simulations—ideal for understanding turning circles and verifying safe manoeuvring for all types of vehicles.
3D Modelling – We create clear and detailed digital models of the site, which help illustrate ground levels, key design concepts, and engineering decisions. These are especially useful for communicating proposals to planning authorities and other stakeholders.
Car Parking and Hard Landscaping Design – Tailored layouts including parking bays, circulation patterns, and hard landscaping schemes, complete with detailed specifications for road make-up and finishes.

At HGC, we strive for excellence in the quality of our services using engineering and mathematical principles, environmental sustainability, and commercial awareness.
