Get the low down from HB Tunnelling

Article: Heading Down to Kensington High St

Holland Green is a prestigious development of 3 new apartment buildings, grouped around the proposed new home of the Design Museum at the south of Holland Park. The buildings are grouped around the new Design Museum (former Commonwealth Institute exhibition hall). The 62 flats will comprise 9 x 1-bedroom, 13 x 2-bedroom, 28 x 3-bedroom, 11 x 4-bedroom and 1 x 5-bedroom units. The new buildings are arranged parallel with the exhibition hall, creating strong cubic shapes in a park setting. They range from 7 to 9 storeys high, together with a secure basement car park, a spa and entertainment rooms.




HB Tunnelling were approached by the Client/Consulting Engineers to look at the best approach to connect an 300mm foul line from the site to the existing foul sewer located within the new prestigious residential development of Holland Park Kensington High Street. After viewing the requirements of the client and site constraints, HBT were able to offer a timber heading from the site to the existing foul sewer as this offered the least disruption to local residents & road users. HBT commenced works with the temporary works design for steel framed shaft & timber heading.

Shaft was completed with 1 week, once the shaft was down into position then works could commence on the timber heading towards the existing foul sewer.

The timber heading was undertaken in dry gravel conditions, which where ideal for the timber heading tunnelling technique.




Once the existing main sewer was reached, the connection was undertaken & the new 300mm pipe was
connected, works then comprised on the lay & backfilling of the timber heading with dry lean mix concrete surrounding the new 300mm pipe.




The client said “Working with HBT was a breath of fresh air, the work was truly top class”.
