Diamond drilling is a quiet, non-percussive way of forming holes and openings. The result is free from bursting or spoiling and requires little or no reinstatement work. Water and dust control attachments can be used where clean environment is being worked in.
There are two main types of diamond drilling used: wet drilling and dry drilling – both techniques providing precise holes through all types of base materials such as mass concrete, reinforced concrete, brick masonry, and block work.
Different attachments range from trailer mounted rigs, hand-held drill motors, twin column assemblies, and automated rigs, all of which are used and specified to suit all drilling environments.Having the right drill rig and set-up can be the difference between a successful and non–successful operation being carried out.
Dust Controlled Chasing
Chasing is often associated with Mechanical & Electrical trades where chases for conduits and pipework are required in a wall, floor, or ceiling of masonry or concrete structures.
We carry out chasing using hand held equipment with a blade attached. Two slots are cut at a predetermined depth and then the centre of the channel is removed using a lightweight hand held breaker.
By attaching vacuum equipment, dust is controlled and contained before it reaches sensitive areas or other trade people working adjacently.
Floor chasing is often done using electric or petrol driven floor saws that are more compatible with this type of application. The extra power that the saws generate makes the cutting of larger volumes of work easier, especially when dealing with hard material like concrete. Once cut, the material in-between can be removed using percussive or less disruptive methods.
Percussion and Rock Drilling
Percussion and rock drilling use rotary percussion or compressed air drills for forming holes. This equipment can be hand held or a frame-mounted machine is commonly used when drilling non-reinforced concrete or brickwork.
Unlike diamond drilling, percussion and rock drilling is a hammer action technique which vibrates the material loose with its tungsten carbide tips, clearing the hole as it proceeds. It is commonly used for dowel bar insertion and resin anchors due to the rough sidewalls that are left once drilled.
Structural engineers prefer this method of drilling as epoxy resins adhere / grip more thoroughly to textured / roughened surfaces.
