Detonating cord has a variety of uses in quarrying, mining, civil engineering and other specialist applications. Low strength detonating cords are typically used for the initiation of shock tube in both quarrying and demolition. Higher strength cord is typically used in pre-splitting applications or as a main charge in demolition.
The multilayer construction of the cord ensures a high resistance to tension and abrasion whilst in use.
EPC-UK supply Daveycord and Seicord with the following core loadings and reel lengths:
Daveycord 5g – 200m reel.
Daveycord 12g – 125m reel.
Daveycord 20g, 40g and 70g – 100m reel.
Seicord 100g – 50m reel.

|Use of the Product||Recommended use: the product is generally used in excavation and demolition work and in the mining industry.
It can also be used as a linear charge explosive whenever allowed by the current state of the art, for example to produce isolated blocks of rock, for controlled demolitions, for contour and preliminary cutting, and detonation transmission.
Never use in the presence of firedamp.
Not recommended use: the intended use is specified above. Other uses are not recommended unless an evaluation is conducted before starting use, which provides evidence that the associated risks are being monitored.
