FREQUENTLY ASKED QUESTIONS

Aggregate size

Aggregate size is not limited by the use of AKS. The knobs are designed to provide outstanding anchorage, regardless of whether small or large aggregate is used in pre-cast or in-situ cast installations - so long as the mix is dense / well-graded.

Strength of concrete

Concrete should be designed to deal with the structural requirements of the project. AKS will provide excellent pull-off resistance when used in sound concrete, which is free of honey-combing and laid in accordance with generally accepted good practices.

Height of pour

All aspects of normal concrete mix design, placing and vibration apply - except where specifically mentioned.

Curing

A further benefit of using AKS is that it provides a permanent waterproof skin to the concrete, which traps the water in the mix and ensures good hydration behind all lined surfaces.

Cleaning and repairs

A definite advantage of the AKS system is the ease at which it can be repaired and maintained. Cleaning is also not a problem.

Removal of knobs

Wherever necessary, knobs can simply and cleanly be removed with an AKS Lining System knob cutter.

Adhesion to shutterboard

Double side tape offers an excellent method of adhering AKS to timber or steel formwork. Contact AKS Lining Systems for further details.
