In today’s construction and infrastructure landscape, effective stormwater management is no longer optional—it’s a necessity. Attenuation tanks have become essential in the design of resilient and sustainable developments. For civil engineers tasked with ensuring these systems are fit for purpose, Enviroseal stands out as the trusted partner across the UK and Europe.
A Trusted Partner in Stormwater Management
Civil engineers face growing pressure to deliver drainage systems that are both high-performing and compliant with stringent environmental standards. At Enviroseal, we work in close collaboration with engineers from the earliest stages of each project. Our ability to design and install tailored attenuation tank solutions gives engineers the peace of mind that their specifications will be met, both technically and practically. We assess every site individually, considering ground conditions, hydrological data, catchment area size and planning constraints. This allows us to propose systems that are not only effective, but also aligned with the unique demands of the project from both a technical and regulatory perspective.
Proven Material Quality and Technical Assurance
One of the primary reasons civil engineers recommend Enviroseal is our use of high-performance materials from globally recognised manufacturers. Whether working with modular crates, concrete tanks or HDPE-lined systems, we prioritise durability, environmental resilience and product traceability. These are not off-the-shelf solutions—they are engineered to perform reliably for decades. Engineers appreciate that each component we use comes with full certification and performance data, allowing them to sign off on systems with confidence. This attention to quality translates directly into long-term operational reliability.
Expert Installation by Certified Technicians
Enviroseal installations are carried out by highly trained, in-house technicians, many of whom are CSWIP-certified by TWI. This means every liner, joint and outlet structure is installed to an exacting standard. Engineers trust our teams to execute installations that meet specifications precisely—reducing risk, avoiding delays and eliminating the need for rework. Our teams work quickly, safely and professionally in a range of environments, from active construction sites to constrained urban developments. For engineers managing timelines, safety protocols and contractor coordination, this professionalism makes all the difference.
Streamlined Project Delivery That Engineers Rely On
We understand how important coordination and timing are on civil engineering projects. Enviroseal’s project managers ensure that logistics, materials and equipment are planned and delivered efficiently to avoid site congestion or scheduling conflicts. Our team proactively communicates with contractors, consultants and local authorities, ensuring that everything aligns before ground is broken. This attention to logistical detail allows civil engineers to focus on the bigger picture, knowing that stormwater installation is being managed with care and precision.
Rigorous Testing and Compliance Documentation
Before handover, each system undergoes a comprehensive round of testing and commissioning. Civil engineers rely on us to deliver not just an installed system—but one that performs exactly as intended. From watertightness verification to hydraulic performance testing, we ensure that every attenuation tank is 100% functional, compliant and documented. We provide detailed quality assurance records, test results, maintenance guides and warranty documentation, so engineers can meet client expectations and regulatory requirements with ease.
Backed by a 25-Year Warranty
Enviroseal offers a 25-year warranty on both materials and workmanship for all attenuation tank projects. This gives civil engineers additional assurance that the systems they specify will perform for the long term and be supported by a provider with a strong track record of accountability.
Supporting Sustainable, Resilient Infrastructure
Attenuation tanks are central to modern sustainable drainage systems and Enviroseal’s solutions support long-term goals for resilience, climate adaptation and environmental protection. Engineers who work with us know they are contributing to infrastructure that meets today’s challenges while anticipating tomorrow’s needs. With a broad portfolio of successful projects—from residential developments to major infrastructure—Enviroseal continues to be the provider that engineers turn to for reliability, quality and results.
