Description
Cromwell walling from Marshalls provides the appearance of natural stone walling at an affordable price. Using Yorkstone aggregates quarried from the same natural sources as those used for natural stone walling to closely replicate the visual and textured characteristics of natural stone.
Features and benefits:
- The hydraulic press manufacturing process results in low water absorption, ensuring the high-quality appearance is maintained over a long-term period.
- The pressing process also delivers dimensional accuracy for time savings on site, while still achieving the visual impact of random and variably sized natural stone walling.
- Available in three distinct styles – Pitched Face, Split Face or Rustic.
- Rough effect, with each block displaying a distinctive raised centre.
- Hydraulically pressed concrete.
- Manufactured in accordance to BS EN 771-5 : 2011 + A1 : 2015.
