Interventions in sewers, canals, and stormwater networks
Works
Resisting aggressive waters and ensuring long-lasting interventions
Sewers and wastewater treatment plants can undergo physical and chemical aggressions that damage the concrete of the pipes and water treatment reservoirs. For example, concrete corrosion is a significant issue that can have multiple causes, such as sulfuric acid created by bacteria present in the sludge formed in the pipes.
The presence of other organisms, such as fungi, which also degrade concrete, can also be noted. As for sewage, it becomes increasingly aggressive over time, impacting the quality and lifespan of sewage pipes and treatment plants. This phenomenon is due to modern drainage systems that separate rainwater from wastewater. This increases the concentration of aggressive substances in wastewater, leading to the corrosion of pipes and increasing the risk of clogging, leaks, environmental pollution, and even pipe collapse. Therefore, it is important to protect the concrete with a coating capable of resisting these various aggressions and that can be applied in a humid environment.
Solution
Natural cement PROMPT Vicat has the particularity of adapting to numerous water and sanitation works.
How ?
Thanks to its quick execution and excellent adhesion, which allows for effective intervention and good waterproofing. Indeed, natural cement PROMPT can resist up to pH=4 to acidic and sulfate waters, an ideal resistance for aggressive waters. Thanks to its fineness, it can be used on all types of construction materials. Adhesion varies depending on the dosage implemented. The higher the dosage, the greater the adhesion.
Technique
The advantage of this technique is to achieve a result with a single product but for multiple uses. Indeed, natural cement PROMPT can be used in pure paste for waterway blindings, in mortar for waterproofing plaster, or even in concrete if a large volume is required.
It should be noted that the required qualities of waterproofing and resistance to aggressive waters or seawater will imply a high dosage of natural cement PROMPT, particularly in the case of mortar.
Fields of application
Natural PROMPT Vicat cement can be used for various water and sanitation projects, including repair work involving mortars and concrete in sewers, stormwater networks, channels, drains, manholes, canals, sluices, and even leveling under waterproof membranes.
Benefits of its application
PROMPT natural cement offers numerous advantages. One of its properties is its waterproofing function, making it suitable for water and sanitation projects, whether for urgent small sealings, larger sealings, roadworks, or protection against seawater.
Additionally, PROMPT natural cement demonstrates good resistance to pure water, acidic conditions (pH=4), sulfates, and even seawater (NF P 15-314). It also allows for rapid return to service, exhibits excellent adhesion on various surfaces, and boasts outstanding durability due to its mineralogical composition.
Lastly, it provides an economical and long-lasting solution.
Advices
The setting time can be adjusted using the TEMPO retarder. Depending on the temperature and dosage, the setting time can be adjusted from a few minutes to over an hour.
