Frequently Asked Questions
How do I determine the correct anchor block weight?
Weight selection depends on load demand and environmental conditions.
Are your anchor blocks suitable for tidal and marine exposure?
Yes. Our concrete mixes are suitable for aggressive exposure classifications, including coastal and tidal environments.
Can lifting points be incorporated?
Yes. We can cast in lifting anchors or eyes to suit safe handling and installation requirements.
Are these suitable for pontoon anchoring?
Yes. Precast anchor blocks are widely used for securing floating pontoons in rivers and marinas.
Can they be used for temporary works?
Yes. Many contractors use them for temporary installations where recovery is required.
Do you offer custom sizes?
Yes. Blocks can be manufactured to suit required weight, footprint or connection detail.
