McBreen Enviro UK Tackle Infiltration Challenges with K-Prema Internal Pipe Seal.

S1E support McBreen Enviro UK to successfully address ground water infiltration with K-Prema Mechanical Seal.

In Gloucester, McBreen Enviro UK faced an issue involving groundwater infiltration into a newly installed, unconnected sewer network. This network, comprising 120-meter-long sections of 1500mm diameter concrete pipes, was experiencing rapid water ingress, threatening the new drainage systems integrity and functionality.

A comprehensive CCTV drain survey, confirmed groundwater infiltration at several joints along the network. This was communicated to the Client. 

The challenge was to find a cost-effective repair method as traditional non dig repair techniques involving extensive machinery were too expensive, as well as a repair to suit a large diameter pipe and suitable for operations to be carried out in a confined space.

Collaborating with S1E Ltd:Specialist Suppliers of Trenchless Technology, it was recommended to use mechanical pipe seals from the K-Prema range. The K-Prema Internal Pipe Seal System includes a large EPDM rubber sleeve and retaining clamping bands made of high-grade 304 stainless steel, suitable for a range of applications, including sewage, water, oil, and air.

Following a meticulously clean and preparation of the pipe, the dedicated technicians from McBreen Enviro UK, undertook a challenging 60m ascend to the infiltration points within a massive 1,500mm diameter concrete pipe. Their commitment to efficiency and safety was evident at every stage of the project, with a rescue team on site and risks efficiently assessed.

Despite the large pipe diameter and long lengths of the pipe, the team installed six 1,500mm internal mechanical pipe seals, with each pipe seal. The K-Prema solution minimised disruption to the system and avoided extensive excavation, as well being significantly more cost-effective than traditional repair methods, meeting the client’s budget constraints.

Even with the challenges posed, the efforts from McBreen Enviro UK team, ensured a successful project completion, with a second phase due to commence in the following weeks.

Features and benefits of K-Prema Mechanical Internal Pipe Seal include:

• Versatility:Suitable for a range of large diameter pipes; the K-Prema mechanical seal can be used on an array of pipe materials, including concrete, steel, cast iron, PE, glass fibre, and others.
• Durability:Manufactured from WRAS-approved material, the K-Prema seal ensures long-lasting performance, even in challenging environmental conditions.
• Reliability:Withstanding internal pressures of up to 20 bar, the K-Prema seal provides a reliable solution for sealing infiltration points and preventing future leaks.

McBreen Enviro UK commented:“The decision to choose the K-Prema mechanical seal was a strategic one; for its cost-effectiveness, ease of installation, and compliance with the Water Authority specification. S1E’s support throughout the project was invaluable, from their expertise in the product and the seamless supply.”

They continued, “The success of this project was down to how simple and easy it was for the team to install the K-Prema seals. When you’re up against tight deadlines it’s important to be using solutions that are efficient as well as reliable.”

In conclusion, the collaborative effort between S1E Ltd and McBreen Enviro UK demonstrates how innovative solutions and a commitment to excellent service can overcome complex infiltration.
