Manhole Cover Cushion

rap-o-home

Also known as Rap-O,  manhole cover cushion is a soft, pliable, round cord, which is impregnated with asphalt and is approximately 1/2″ in diameter. It will silence noisy manhole covers and reduce cover and seat wear. Cut the 96″ length as needed and leave an overlap at the splice joint.  Trowelex offers competitive pricing.  Contact us today for a quote.  Full Data Sheet located here.


Manhole Inserts

Let’s face it.  Water Treatment is not cheap.  During an average rainfall, thousands of litres can infiltrate your Sanitary Sewer System increasing demand on your treatment systems. This unneccessary inflow can cost taxpayers thousands.  Our Manhole inserts can dramatically reduce these costs, allowing you to focus your budget on improvements and upgrades.  In as little as a year, the product can pay for itself, are easy to install, and maintenance free.

Got odour problems? We carry Odour-Eater inserts (pictured) to trap odours caused by Hydrogen Sulphide (H2S) and Methyl Mercaptan (CH4S).  Keep your citizens happy.  Contact us today for more information.
