Wastewater upkeep and restore specialist Lanes Group has carried out the primary spray lining venture commissioned by Scottish Water to rehabilitate chambers serving a big moist properly.
The revolutionary venture has efficiently strengthened the 2 chambers on the outfall of the moist properly at Decrease Largo, Fife, stopping the property from having to be excavated and changed.
Lanes Group, which is a framework provider for Scottish Water throughout the entire of Scotland, prompt the answer after it was discovered that the chambers wanted to be sealed and strengthened.
The corporate carried out the work for Morrison Building, a framework contractor delivering design, engineering and development companies for Scottish Water.
Matthew Anderson, Connection Supervisor at Morrison Building, mentioned: “We’d wish to thank Lanes Group for making use of the revolutionary Hermes M-Coating system, together with ERGELIT dry mortars to those very deep chambers.
“That they had been badly affected by hydrogen sulphide corrosion. The spray lining work saved us from having to put in short-term works in extra of six metres deep to interchange the asset. The carbon financial savings alone have been enormous.”
David Beveridge, Regional Gross sales Supervisor for Lanes Group, mentioned: “Until an acceptable no-dig rehabilitation resolution was discovered, the one possibility was to think about changing the chambers.
“This may have been a significant engineering job, carried out over many weeks, with vital mitigation in place to make sure continuity of wastewater companies for wastewater clients.
“The answer Lanes supplied, as a substitute, was accomplished over six days, with all required outputs achieved. This was each extremely cost-effective and very sustainable, with no inconvenience for patrons.”
The spray lining was carried out by Lanes Group Sewer Renovation.
One of many chambers was shaped from concrete rings and was 6m deep and 1.2m in diameter. The opposite was a brick-lined sq. chamber that was 6m deep and 2m broad.
Every chamber was first cleaned by a remotely-controlled excessive strain water jetting system. Mortar was then injected into the joints of the concrete ring chamber to seal them.
In a remaining course of, one other remotely-controlled rig was lowered into the chamber to spray-line its partitions with a specialist dry mortar.
The pc-controlled system routinely accomplished 50 coats of every chamber to create a liner 10 millimetres thick, with the coating cured in 24 hours.
Lanes Group Sewer Renovation Technical Supervisor Gary Carey mentioned: “The material of the chambers had been broken by numerous contaminants, together with raised ranges of hydrogen sulphide.
“The mortar we utilized is resistant to those chemical compounds and creates a sealed drainage system with the required structural energy and long-term safety in opposition to water infiltration and leakage.”
Spray lining wastewater property is a way more sustainable than excavation and substitute, offering an answer with a smaller carbon footprint.
Normally, it is usually a lot faster, safer and simpler to hold out, utilizing much less tools and supplies and extra restricted confined house entry.
Gary Carey defined: “On this occasion, the moist properly chambers have been situated simply off a single-track rural highway however have been simple to entry by the small Lanes Group spray lining staff.
“Had the chambers wanted to get replaced, the identical wouldn’t be the case for an excavation staff with the vary of plant and supplies they must deploy.”
