FREQUENTLY ASKED QUESTIONS

What about steps in the slab?

These can be incorporated with a competent contractor.

What about surface topping before?

This needs to be looked into, but can sometimes be laid over a topping – with sufficient pull off tests (topping dependent)

What about surface toppings afterwards?

We can advise on how to incorporate toppings

How far does the laminates protrude out from the surface?

Above – Depends on laminate

What about fire rating?

Don’t bother as it is expensive and not needed in 99.9% of times. Consultant should do a Rational Fire Design with min (DL+LL) and structure needs to have enough inherent capacity to withstand fire load case. In 99.9% of the time, this is OK and FRP does not need fire protection.

What about recessing and hitting existing reinforcing?

Reinforcing should be at least 20 mm below the surface- however this can be an issue and has happened in the past – we then liaise with the engineer and come up with a solution.

What happens is there is cracking in the existing structure?

We can rectify this using our specialist contractor experience in crack remedials and injection of a low viscosity resin.
