QuantiCast is a two-component epoxy chocking or grouting system. It consists of resin and hardener and is widely used for the installation of various machinery and equipment on board ships and in industrial plants. Due to its advanced formula, QuantiCast achieves 100% surface profile coverage, maintains precise equipment alignment and exhibits high compressive strength and long-term durability.
QuantiCast is very competitively priced and is type approved for marine use by DNV-GL and by Lloyds Register. It is globally available in bin sizes of 6.2 litres (9.8 kg / 21.5 lbs weight) through the QuantiServ organization.
QuantiCast has been specifically developed for chocking precisely aligned equipment such as marine main propulsion machinery. QuantiCast is suitable to withstand the harshest of environments. It is characterised by high impact and compressive strength and is resistant to a wide range of chemicals such as fuel and lubricating oils.
The ideal thickness of the poured epoxy is 10 – 70 mm. This makes QuantiCast the material of choice for a wide range of applications.
Typical marine applications include foundations of main and auxilliary engines, gear boxes, alternators, thrusters, steering gears, pumps and winches/windlasses. Further common applications include the fixation of stern tube and strut bearings as well as pintle and rudder bearings.
QuantiCast is suitable for a very wide range of industrial applications, both indoors and outdoors. Examples include various machinery sole plate and skid foundations and the fixation of crane rails.
Advantages of QuantiCast
The QuantiCast epoxy chocking compound has many advantages compared with traditional cast iron chocks:
- No need for precise surface (in-situ) machining and preparation
- No shrinkage or creep, maintains precise alignment
- Ease of application, short construction time
- Excellent adhesion on various substrates (concrete, steel, …)
- High compressive and impact strength
- Highly resistant to chemicals, solvents and moisture
- Tough, durable and very corrosion resistant
- Decreases operating machine noise and shock considerably
- Low total cost

The packaging of QuantiCast is such that one bottle of hardener matches one bin of resin. This ensures the correct mix ratio and applies to the great majority of situations.
On rare occasions, however, the profile of the pour is such that the ratio of the epoxy’s exposed surfaces to its total volume is very low. In such cases the heat that is generated during the exothermic curing reaction – when the resin molecules are cross-linking – cannot be dissipated quickly enough. When the heat cannot escape from the pour, then it builds up and leads the pour to cure ever faster as epoxy cures faster at higher temperature. The result is known as an uncontrolled exothermic reaction. It must always be avoided as it can lead to cracks in the resin and to curled surfaces.
Some advanced materials provide for the possibility to vary the resin/hardener mix ratio to control the curing temperature according to pour volume and ambient temperature. QuantiCast provides for this. The following table serves as a general guide.
All our epoxy resin technicians are experienced and certified to work with QuantiCast. But they can work equally well with other common brands of epoxy material. Our offering includes any, or all, of the following:
- supply of epoxy resin, hardener and consumables (damming material, cleaner, …)
- devising of a chocking plan
- calculating the correct tightening torques of the foundation bolts
- assisting the customer to get classification approval, if any is required
- executing the work at site (preparation, pouring, post-pouring work)
