HEX Concrete Earth Pit Chambers – Ready-Made Square & Round, Load Bearing up to 5 Tonnes

HEX concrete earth pit chambers are ready-to-use, robust chambers that replace the tedious brick-and-cement pits built on site. They are made with a proprietary mortar formulation of prime materials and additives that keep them relatively light for concrete, give water resistance (low porosity) and good insulation, and remain stable under all weather conditions. An earth bar for multiple connections can be fitted diagonally across the slots provided. Made by HEX, the brand of Brass Copper & Alloy (I) Ltd., Mumbai — an ISO 9001 company whose products are tested by CPRI (India), UL (USA), KEMA (Netherlands) and SIRIM (Malaysia).

At a glance

• Construction: precast proprietary mortar with additives; low porosity
• Shapes: square (concrete or metal cover) and round (metal cover)
• Load-bearing capacity: 5 tonnes (square range); 3 tonnes (round HCEPR-CI)
• Weight: 25 to 130 kg
• Tested: load-bearing capacity to IEC 62561-5 (TCR Engineering Services) on the 310 mm square chamber

Why choose a HEX concrete pit

• No site masonry — drop in a finished chamber instead of building one in brick and cement.
• Water resistant and insulating — low porosity mortar with additives.
• 5-tonne rating across the square range.
• Ready for an earth bar — slots take a copper bar diagonally for several connections.

Frequently asked questions

Why use a precast concrete earth pit instead of building one?

It saves the time and labour of a brick-and-cement pit on site, and the proprietary mortar gives water resistance, insulation and a tested load rating.

What load can it take?

The square HCEP range is rated at 5 tonnes; the round HCEPR-CI at 3 tonnes.

Can I fit an earth bar inside?

Yes — an earth bar can be fitted diagonally across the slots provided; HEX copper earth bars are listed on the earth pit accessories page.

Is there a version with a metal cover?

Yes — HCEP-M (square) and HCEPR-CI (round).
