SANI-TRED sealing solution extends manhole lifespan in recent infrastructure project
(UI) – Manholes serve as access points to underground sewer systems, allowing for inspection, maintenance, and repair works. However, if left unsealed or improperly sealed, they can become a source of numerous problems.
Unsealed manholes are susceptible to infiltration of groundwater, which can overload the wastewater system, leading to increased treatment costs and potential environmental contamination. Additionally, unsealed manholes may release foul odors, attract pests, and pose safety hazards to both workers and the public.
Sealing solutions such as SANI-TRED can be applied to various manhole materials, including concrete, brick, and metal, making it a versatile solution for different infrastructure projects. It adheres strongly to the substrate and can accommodate structural movements, ensuring long-lasting performance.
The application process of such solutions is straightforward. It eliminates the need for complex equipment or multiple layers, reducing labor costs and project timelines.
For example, SANI-TRED’s Fusion to the concrete surface allows SANI-TRED PERMAFLEX to retain negative hydrostatic pressure at the microscopic level to eliminate “weeping” before the water pressure has an opportunity to reach the Permaflex coating membrane surface, accumulate behind the main sealing membrane surface, create blisters and eventually fail as experienced with other coatings that have attempted to retain negative hydrostatic waterproofing or “TANKING”. These “tentacles” work like small, high-pressure O-rings for a manhole cover seal. The tentacles anchor, lock to the concrete and protect the actual PERMAFLEX from ever delaminating or blistering.
In a recent infrastructure project, SANI-TRED was implemented to seal a series of deteriorated manholes. The project involved cleaning and preparing the manholes, followed by the application of SANI-TRED products. The liquid rubber technology seamlessly sealed the manholes, providing an impermeable barrier against water infiltration. The project’s success showcased SANI-TRED’s ability to extend the lifespan of manholes while minimizing maintenance requirements.
