It has been around 35 years since WP Metals developed the bottom driven mini pile casing. We achieved this by working closely with key players in the piling sector and coming up with a product that fulfilled our customers’ needs. We are market leaders and work hard to maintain our position as a reliable and consistent supplier for a large proportion of piling contractors in the UK

WP’s casings are used in a wide variety of applications. Bottom driven is the main application but increasingly we see our larger diameters being used with  various drill systems as sacrificial lining for the pile. Water well drilling and boreholes is another area where WP have seen demand increase.

From the largest ground engineering companies to the sole trader with years of experience; our customers place their trust in us because they know we will deliver a quality product straight to site with minimum interruption to the program of work.
