• 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

History of the Ducorit® onshore to offshore

• The Ducorit® OC brings a greater versatility to

the Densit® brand
