The whole of Maderia walk appears to made out of Pullham Rock or Pulhamite an artificial rock manufactured by James Pullham and Sons
One of the most successful creators and suppliers of artificial rockwork and features was the firm of James Pulham who, for over a century from the 1830s to the 1940s, designed and built rockeries, rock gardens and grottoes in parks and gardens all around the UK, using their proprietary artificial cement render, called Pulhamite.
Pulhamite took several forms but is most recognisable as a distinctive pinkish, lime-based cement. This was used by the firm from the 1830s to the 1870s to cover brick-built foundations and was worked to simulate real rocks. Great care was taken to make the rockwork realistic, even copying the local geology and including local rocks in the finished product. Pulhamite was in great demand during this period, with over 170 major projects constructed around the UK.
Pulham prided themselves on the quality of their product and 'Durability guaranteed' was their company slogan. This durability was to be tested to its limit in public parks during the twentieth century, when lack of maintenance allowed weeds and scrub trees to encroach on many of the features and the water was turned off on the waterfalls.
