This 750x600mm precast concrete top section is designed to complete the construction of a domestic House Inspection Chamber and comes complete with a 695x540x60mm concrete cover slab

This section can be quickly and easily jointed on top of a main chamber section with bituminous or butyl compounds, providing a watertight seal without the use of a concrete surround.

Manufacturer’s Advice: For depths in excess of 1.5m the use of a concrete surround is still recommended.

House Inspection Chambers provide a flexible solution to the demands of domestic drainage access installations. Each section features tongue and groove detailing, which allows for a more accurate build and helps with on-site placement. They are designed to be easy to handle and install, keeping the necessary below ground excavation level to a minimum.

Top Sections designed for metal cover and frames are also available as an alternative to finishing with a concrete slab.

The Marshalls CPM range of precast concrete inspection chambers are available in a variety of depths and are manufactured to BS EN1917 / BS 5911-4.

Key Features of CPM Concrete Products:

  • Quality - Precast concrete drainage products are manufactured in accordance with the relevant BS EN 1916/7, BS EN 5911 and CE marked where applicable. Goods are certified by Quality Assessment under the Kitemark Scheme and ISO 9001:2015.
  • Sustainability - Concrete pipeline systems are one of the most sustainable options available, they are manufactured from responsibly sourced materials, and can be made using recycled aggregates and cement replacements.
  • Proven Strength - They have a proven life of over 120 years, in normal groundwater conditions, are not weakened by fire or moisture and do not lose their shape. They are resistant to DC4 and impacts such as jetting, so blockages can be cleared easily.
  • Installed Cost Savings - Precast concrete pipes are rigid structural elements that do not always require a full granular surround, saving time in bedding and compaction. Excavated material can be reused and imported granular material can be reduced to a minimum.
  • Durability - Due to the inherent strength and durability of the Marshalls CPM precast concrete products, they are highly abrasion and corrosion resistant and don't lose strength over time.
  • Design Flexibility - Precast concrete drainage products can be used for a number of purposes, including sewerage and sustainable urban drainage systems (SuDS) applications such as stormwater attenuation and storage.
  • Water Tightness - Concrete pipes and manholes are designed to be watertight and are tested to pressure levels equivalent to a 5 metre head of water.
  • Fire Resistant - Concrete is naturally fire resistant.
