As a pre-requisite for the main Orange Bastion contract, Stonehouse were requested to waterproof one of the adjacent series of smaller vaults within Chatham Counterguard. Her Majesty’s Government of Gibraltar had a plan to upgrade all vaults into commercial space and public facilities.

We installed a full cavity drain membrane system to walls, floors and arched ceiling. The floor was screeded and all surfaces were dry lined in preparation for tiling, fittings and fixtures.

The success of this installation resulted in the appointment of Stonehouse as contractors for The Orange Bastion the following year.
