Selecting the correct class of cover is crucial to ensure safety and prevent damage.

Replacement Manhole Covers Made Easy 
We often receive inquiries from customers needing replacement manhole covers due to damage from vehicles or wear and tear. It's essential to choose a replacement lid that matches the frame to maintain structural integrity and weight loading capacity. If the lid needs replacing, it's likely the entire cover and frame will require replacement unless the lid was recently installed.

Measuring and Installing the Right Cover
When replacing a manhole cover, it's crucial to measure the size of the manhole or inspection chamber below, rather than the frame or lid size. Proper installation involves removing the old frame, leveling and bedding in the new frame, backfilling around it, and then installing the cover. For plastic inspection chambers deeper than 1.2m, a reducing ring may be needed to comply with building regulations.

Enhance Aesthetics with Recessed Manhole Covers 
Recessed chamber covers offer a sleek solution for maintaining access to drainage systems without sacrificing aesthetics. They can be used internally or externally to create a continuous floor finish while ensuring easy access to the drainage system.
