Subcon’s concrete block mattresses have been rigorously tank tested to optimise the their on-bottom stability by refining their lift and drag coefficients. Having a larger block coefficient ensures that there is greater volume to area ratio providing enhanced stability characteristics.
Our mattresses can be manufactured with the following features;
- A unique staggered block design to reduce current flow through the mattress and reduces scour under mattress.
- Production as close to your loadout site as possible to minimise transportation costs.
- UV stabilised polypropylene rope and high strength concrete to ensure the required design life for the mattresses is exceeded.
- High density concrete for improved weight to volume ratio and mattress performance.
