• Why the new product? In response to our Clients looking for an
alternative to a UHPC but ‘better than’ an OPC
The evolving offshore foundation market –ie. new foundations requiring different specialist materials
Particularly well suited to the bolted/grouted flange MP/TP where no structural requirement but anticorrosion packing
Mass filling of the SBJ where inexpensive product with low wastage is important
Ducorit® OC (Offshore Concrete)

• The Ducorit®OC has evolved from
on onshore product – the A2G
• It has been used as structural
grout in concrete tower joints
• It is very easy to mix and pump
(we have pumped 120 meter up)
• Max aggregate size 1 mm
• Potential for silo technology
