Should I seal my paving?

Marshalls as a company believe it is not necessary to seal our paving. This is due to many factors, the reasons being amongst others that:

  1. Sealants have to be applied to a surface which is clean, dry & free from dust.
  2. Sealants may affect the appearance of the units and wear unevenly.

Which flags are slip resistant?

All our paving is slip resistant provided that the units are maintained at the required intervals to prevent them from potentially becoming slippy with a surface build up of dirt, detritus and algae for example.

Which flags are suitable to be laid around a swimming pool?

Pressed Concrete paving and Natural Stone Paving are suitable to use around a swimming pool. Avoid Wet Cast units (such as Coach House and Heritage) as these will be affected by chemicals in the pool water such as chlorine for example and will suffer from surface crumbling.

What is the difference between concrete and clay block paving?

Besides one being made from clay and one from concrete there are a number of differences between the two.

As clay is a natural material the colour is inherent within it, consequently exposure to Ultra Violet light will not have an effect on the vibrancy of the colour over time.

Concrete however, is a pigmented material and over time and exposure to UV light there will be a reduction in the intensity of colour, this will not be a noticeable change due to the length of time it will take.
