Hydrotrench® drainage mats are a sustainable modular drainage system for landscapes, gardens, hard standings, paved areas, pathways and edges.
Civil Water Management is a specialist in whole system approaches to integrated drainage engineering solutions for rail, highways, civil engineering, public spaces and government agencies.
Its sustainable modular drainage systems have been developed, engineered, tested and trialled with rigour to deliver exceptional performance and reliability.
The company brings together the specialist expertise of its supply chain partners, polymeric scientists, transport authorities, senior engineers, principal designers and contractors from countries across the world.
Advantages
Increased workforce safety
Optimising safety by design in drainage construction by reducing trench excavation requirements, and through the replacement of heavy materials such as filter stone and concrete.
Major cost savings
The streamlined design of sustainable modular drainage systems minimises filter stone and trench depth requirements to overcome costs and constraints while the durable characteristics of rubber / polymeric materials increase asset resilience for enhanced long-term performance.
An exceptional infiltration rate is presented to persistently remove water with increased efficacy, uphold drainage functionality and reduce the maintenance burden associated with conventional 'piped drainage' and concrete systems.
Modular design benefits
The consistency of the drainage materials deployed, firmly delivers on safety by design principles, while enabling significant efficiencies in drainage asset construction to be achieved.
Durability
System lifespan is prolonged through the use of rubber / polymeric materials that ensure long-term durability and resilience are achieved. The UV and chemical resistance of the composites provides resistance to degradation and common chemicals such as petrol, diesel, de-icer, and salt.
Recycled material composition
Conventional materials, such as filter stone and concrete are carbon heavy.
The company supports environmental sustainability by replacing such materials with recycled rubber / polymeric materials.
Reduce carbon footprint CO2e
Civil Water Management takes a firm stance on the drive to net zero and fight against climate change.
End-of-life tyres are a global issue with up to 50% still being incinerated.
It is essential that incineration, landfill and other harmful forms of end of life disposal are dramatically reduced in order that significantly less CO2 is emitted to the atmosphere, and to prevent damage being caused to the environment.
Sustainable modular drainage systems provide an invaluable alternative to harmful forms of end of life disposal, by using a minimum of 90% waste materials in production of drainage units, which in turn enables projects to actively reduce their carbon footprint and environmental impact.
Environmental compliance
Environmental safety is confirmed complying with environmental safety standards.
Heavy metals. Pass.
NF P 90-112:2016 for recycled rubber polymeric materials is free from harmful PAHs.
Temperature resistance
Performance is maintained in both hot and cold environments.
Flexibility
Minor ground movements are accommodated, reducing the risk of system failure.
Load-bearing capacity
Sustainable modular drainage systems are designed to handle standard loading conditions in drainage applications.
