Drainage Contractors in Hertfordshire
Practical drainage solutions designed around ground conditions, long-term performance, and how the site actually behaves.
Drainage Done Properly
Proper drainage starts with understanding the land, not just installing pipework.
Many drainage problems are caused by systems that were designed without proper consideration for ground conditions, water movement, or long-term performance. When drainage is treated as an afterthought, it often leads to flooding, soft ground, repeated blockages, and failure of surrounding structures.
We take a considered approach to drainage. That means assessing how water behaves across and through the site, understanding the type and condition of the ground, and designing solutions that suit the location rather than forcing a standard system into place.
Whether the work involves new installation, modification of an existing system, or resolving a failure, our focus is on managing water correctly and permanently. When drainage is done properly, it protects buildings, ground stability, and the wider site for years to come.
Understanding Ground Conditions and Water Movement
Every site behaves differently when it comes to water. Ground type, natural fall, existing drainage, and surrounding land all affect how water moves across and through a site.
Before any drainage work is designed or installed, we assess the ground conditions in detail. This includes looking at soil type, compaction, permeability, and how water currently behaves during wet periods. Clay, chalk, made ground, and mixed soils all require different approaches, and treating them the same is a common cause of drainage failure.
We also consider how water enters and leaves the site, whether from rainfall, run-off, or neighbouring land. Understanding these patterns allows us to design drainage that works with the natural movement of water rather than fighting it.
By basing drainage solutions on how the ground actually behaves, we avoid over-engineering, under-performing systems, and repeat problems. The result is drainage that functions reliably and supports the long-term stability of the site.
Surface Water Drainage
Surface water drainage is about controlling rainfall and run-off so it does not collect, cause flooding, or undermine the ground.
Problems often occur where surface water has nowhere to go, falls are incorrect, or systems have been installed without considering the volume of water or the ground’s ability to absorb it. This can lead to standing water, soft ground, and damage to hard landscaping and structures.
We design and install surface water drainage systems based on how water enters the site and how it needs to be managed. This can include channel drainage, pipework, soakaways, and connections to existing systems where appropriate.
All surface water drainage is planned around ground conditions, levels, and long-term performance, ensuring water is managed effectively without creating future issues elsewhere on the site.
Foul Drainage and Private Systems
Foul drainage systems need to be designed and installed correctly to function reliably and remain compliant long-term.
We carry out foul drainage works for residential, commercial, and public sector projects, including new installations, alterations, and repairs. This includes pipework, connections, and integration with existing drainage infrastructure where applicable.
For sites without access to mains drainage, we work with private systems such as septic tanks and wastewater treatment plants. Before any system is installed or modified, we assess ground conditions, available space, access, and discharge routes to ensure the solution is suitable for the site.
By planning foul drainage and private systems properly from the outset, we avoid common issues such as blockages, poor flow, maintenance problems, and system failure, delivering drainage that performs as intended over the long term.
Soakaways and Land Drainage
Soakaways and land drainage are only effective when they are designed around the ground conditions.
Many soakaways fail because they are installed without proper assessment of soil type, permeability, or available space. In unsuitable ground, this can lead to water backing up, flooding, or systems that simply do not function as intended.
Before installing or replacing soakaways, we assess the ground to determine whether infiltration is viable and what type of system is appropriate. Where soakaways are not suitable, we advise on alternative drainage solutions that will perform reliably long-term.
Land drainage is used to manage excess water within the ground, improving stability and preventing prolonged saturation. When designed and installed correctly, it supports healthy ground conditions, protects structures, and reduces ongoing drainage issues across the site.
Drainage Repairs and Failed Systems
Drainage failures are often the result of systems that were poorly designed, incorrectly installed, or never suited to the ground conditions in the first place.
We are regularly called in to investigate drainage problems such as recurring blockages, standing water, soft ground, and systems that have stopped working altogether. Rather than applying temporary fixes, we focus on identifying the underlying cause of the failure.
Our repair work can involve clearing and modifying existing drainage, replacing collapsed or undersized pipework, improving falls, or redesigning parts of the system to suit the site. In many cases, resolving the issue requires excavation and reworking sections of the drainage rather than superficial repairs.
By addressing the root cause, we provide repairs that restore proper function and prevent the same problems from returning.
Working With the Land and Surrounding Environment
Effective drainage works with the land rather than trying to force water against its natural behaviour.
When planning drainage, we consider how the ground, surrounding land, and existing features interact with water. This includes soil structure, natural falls, planting, trees, and how the site responds during prolonged wet periods. Ignoring these factors is a common cause of long-term drainage problems.
Where possible, we design drainage solutions that support healthy ground conditions and integrate with the wider site. This can include protecting soil structure, directing water in a way that benefits planting, and avoiding unnecessary disturbance to established areas.
By taking a considered approach, drainage not only manages water effectively but also supports the long-term stability and function of the site, reducing ongoing issues and maintenance.
Who We Carry Out Drainage Work For
We carry out drainage works for clients who need systems that are planned properly and built to perform long-term.
Our drainage work is undertaken for:
Commercial clients — developers, contractors, and consultants requiring reliable drainage solutions as part of construction or infrastructure projects
Councils and utilities — drainage, wastewater, and ground-related works where compliance, durability, and long-term performance are essential
