DIAMOND DRILLING / SAWING

PEXHURST
Bermondsey

Pexhurst Bermondsey

The Brief

Requirement: Diamond Drilling and Diamond Sawing

An opening 8m x 3m was required through a Brickwork Wall up to 700 mm thick on the ground floor of a 6 storey building leaving clean edges ready to receive new open plan windows. The building also needed to be used at the same time.

The Solution

Project Begins

Diacutt received the instruction to support the building whilst the opening was formed. This was carried out following the design and sequence provided by the Structural Engineer.

Supporting the building

The method required the concrete beams that were bearing on the wall internally to also be supported on Mabey Castellated props as shown on the site photos.

The full building façade also needed to be supported as the opening was being formed.

Wall Sawing

Vertical 400 mm wide slots were formed in the wall by Hydraulic Wall Sawing to avoid vibration and ensure the integrity of the wall in each stage. A vertical cut was made initially plus a horizontal cut with very careful control of the length of horizontal cut to avoid exceeding the capability of span of the brickwork above.

The centre of each section was then removed using Diamond Drilling and Hydraulic Bursting to reduce the noise levels created when using percussive tools. This prepared the openings ready for props to be inserted.

Heavy duty props

The heavy duty mechanical props were then installed as per the photos within the full height slot to support the building above. This sequence was repeated on the adjacent slot until the full width of the opening was fully supported.

Concrete Bursting

Holes are drilled into the structure, and hydraulic pistons Inserted and expanded to form cracks to the exposed edges to minimise the use of percussive tools in reducing the wall to debris.

Vertical Concrete Sawing

The final vertical cut provided a clean line to the full depth of the wall to establish the finished face of the opening.
