Inspection chambers, commonly called manholes, play an important role in our underground drainage systems. They provide an access point for drains to be cleaned, cleared and inspected when required. Inspection chambers are integral to safety and also stop people from entering underground drainage systems without authorisation.
At Cotterill Civils we provide a wide range of inspection chambers to suit your specific needs and budget. Our inspection chambers include adoptable and non-adoptable inspection chambers as well as catchpits, which can take HS®, EN1401 and Twin Wall pipes.
Our inspection chambers and manhole covers also vary in size or shape. So whether you require a round or square manhole cover, internal or external use, a deep or shallow invert, we can help you find the right one.
